ASoC: Explicitly include correct DT includes The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it was merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

ASoC: sgtl5000: Reset the CHIP_CLK_CTRL reg on remove Since commit bf2aebccddef ("ASoC: sgtl5000: Fix noise on shutdown/remove"), the device power control registers are reset when the driver is removed/shutdown. This is an issue when the device is configured to use the PLL clock. The device will stop responding if it is still configured to use the PLL clock but the PLL clock is powered down. When rebooting linux, the probe function will show: sgtl5000 0-000a: Error reading chip id -11 Make sure that the CHIP_CLK_CTRL is reset to its default value before powering down the device.

i2c: Make remove callback return void The value returned by an i2c driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

This would incorrectly write values to bits 4 and 10, which are defined as RESERVED. It would also not set bits 12 and 14 to their correct RESET values of 0x1, and instead set them to 0x0. While the DAP_AVC module is effectively disabled because the EN bit is 0, this default value is still writing invalid values to registers that are marked as read-only and RESERVED as well as not setting bits 12 and 14 to their correct default values as defined by the datasheet. The correct value that should be written to the DAP_AVC_CTRL register is 0x5100, which configures the register bits to the default values defined by the datasheet, and prevents any writes to bits defined as 'read-only'. Generally speaking, it is best practice to NOT attempt to write values to registers/bits defined as RESERVED, as it generally produces unwanted/undefined behavior, or errors. Also, all credit for this patch should go to my colleague Dan MacDonald <dmacdonald@curbellmedical.com> for finding this error in the first place.

ASoC: sgtl5000: Fix VAG power-on handling As mentioned slightly out of patch context in the code, there is no reset routine for the chip. On boards where the chip is supplied by a fixed regulator, it might not even be resetted during (e.g. watchdog) reboot and can be in any state. If the device is probed with VAG enabled, the driver's probe routine will generate a loud pop sound when ANA_POWER is being programmed. Avoid this by properly disabling just the VAG bit and waiting the required power down time.

ASoC: sgtl5000: add multi endpoint support Support multiple endpoints on SGTL5000 codec port when used in of_graph context. This patch allows to share the codec port between two CPU DAIs. Example: Custom STM32MP157C board uses SGTL5000 audio codec. This codec is connected to two serial audio interfaces, which are configured either as rx or tx. From AsoC point of view the topolgy is the following: // 2 CPU DAIs (SAI2A/B), 1 Codec (SGTL5000) Playback: CPU-A-DAI(slave) -> (master)CODEC-DAI/port0 Record: CPU-B-DAI(slave) <- (master)CODEC-DAI/port0 In the DT two endpoints have to be associated to the codec port: sgtl5000_port: port { sgtl5000_tx_endpoint: endpoint@0 { remote-endpoint = <&sai2a_endpoint>; }; sgtl5000_rx_endpoint: endpoint@1 { remote-endpoint = <&sai2b_endpoint>; }; }; However, when the audio graph card parses the codec nodes, it expects to find DAI interface indexes matching the endpoints indexes. The current patch forces the use of DAI id 0 for both endpoints, which allows to share the codec DAI between the two CPU DAIs for playback and capture streams respectively.

ASoC: sgtl5000: Improve VAG power and mute control VAG power control is improved to fit the manual [1]. This patch fixes as minimum one bug: if customer muxes Headphone to Line-In right after boot, the VAG power remains off that leads to poor sound quality from line-in. I.e. after boot: - Connect sound source to Line-In jack; - Connect headphone to HP jack; - Run following commands: $ amixer set 'Headphone' 80% $ amixer set 'Headphone Mux' LINE_IN Change VAG power on/off control according to the following algorithm: - turn VAG power ON on the 1st incoming event. - keep it ON if there is any active VAG consumer (ADC/DAC/HP/Line-In). - turn VAG power OFF when there is the latest consumer's pre-down event come. - always delay after VAG power OFF to avoid pop. - delay after VAG power ON if the initiative consumer is Line-In, this prevents pop during line-in muxing. According to the data sheet [1], to avoid any pops/clicks, the outputs should be muted during input/output routing changes.

ASoC: sgtl5000: avoid division by zero if lo_vag is zero In the case where lo_vag <= SGTL5000_LINE_OUT_GND_BASE, lo_vag is set to zero and later vol_quot is computed by dividing by lo_vag causing a division by zero error. Fix this by avoiding a zero division and set vol_quot to zero in this specific case so that the lowest setting for i is correctly set.

When running a stress playback loop test on a mx6dl wandboard channel swap can be noticed on about 10% of the times. While debugging this issue I noticed that when probing the SGTL5000 LRCLK pin with the scope the swap did not happen. After removing the probe the swap started to happen again. After changing the LRCLK pad drive strength to the maximum value the issue is gone. Same fix works on a mx6dl Colibri board as well.

ASoC: sgtl5000: Fix regulator support Regulator support on SGTL5000 is broken because the VDDIO and VDDA and VDDD should be powered on before enabling MCLK as shown in Figure 4 of [1]. This requires moving control of the regulators from the codec block to the I2C block of the driver. The bulk of this patch consists of swapping the codec device with the i2c client. The new field num_supplies in struct sgtl5000_priv is used instead of ARRAY_SIZE(supplies) to handle the special case when the internal LDO is used instead of external VDDD. Note that ER1 in the SGTL5000 Errata document [2] suggests that all designs should use external VDDD. Since the internal LDO can only be enabled after I2C is available, there's no benefit in treating it as a regulator, so this patch removes the regulator structure surrounding it. Instead, a single block of code in sgtl5000_i2c_probe() performs the initialization sequence in section 2.2.1.1 of [3] and page 26 of [1].

ASoC: sgtl5000: Remove MCLK restriction According to the sgtl5000 datasheet the MCLK frequency range restriction of 8 to 27 MHz only applies when the PLL is used - synchronous SYS_MCLK input mode. When running the codec as slave, the master should generate MCLK in the range of 256*fs, 384*fs or 512*fs, which is called asynchronous SYS_MCLK input mode. In asynchronous SYS_MCLK we cannot have the 8 to 27 MHz check because if we want to play a 8KHz sample rate track, with a MCLK of 8k * 512 = 4.096MHz the current check would return -EINVAL, which is not correct. Remove the 8 to 27MHz frequency check, since this only applies to the synchronous SYS_MCLK input case.

ASoC: sgtl5000: Use the preferred form for passing a size of a struct According to Documentation/CodingStyle - Chapter 14: "The preferred form for passing a size of a struct is the following: p = kmalloc(sizeof(*p), ...); The alternative form where struct name is spelled out hurts readability and introduces an opportunity for a bug when the pointer variable type is changed but the corresponding sizeof that is passed to a memory allocator is not."

This makes the code a bit shorter and cleaner. Since the ASoC core now takes care of setting the bias level to SND_SOC_BIAS_OFF when removing the CODEC there is no need to do it manually anymore either. The manual transition to SND_SOC_BIAS_STANDBY at the end of CODEC probe() can also be removed as the core will automatically do this after the CODEC has been probed.

The first stage is when the platform driver is probed, where some resources are found and initialised. The second stage is via the codec driver's probe function, where regulators are found and initialised using the managed resource support. The problem here is that this works fine until the codec driver is unbound. When this occurs, sgtl5000_remove() is called which is a no-op as far as the managed resource code is concerned. The regulators remain allocated, and their pointers in sgtl5000_priv remain valid. If the codec is now re-probed, it will again try and find the regulators, which will now be busy. This will fail. That's not the only problem - if using the LDO regulator, the regulator is unregistered from the regulator core code, but it still has a user. When the user is cleaned up (eg, by removing the module) it hits the free'd regulator, and this can oops the kernel. This bug was originally introduced by 63e54cd9caa3ce ("ASoC: sgtl5000: Use devm_regulator_bulk_get()")." This reverts commit 63e54cd9caa3ce. Tested on a imx53-qsb board.

With the upcoming consolidation of platform and CODEC controls this will change. Prepare for this by introducing the snd_soc_kcontrol_codec() helper function that will hide the implementation details of how the CODEC for a control can be obtained. This will allow us to change this easily in the future. The patch also updates all CODEC drivers to use the new helper function.

ASoC: sgtl5000: clean up sgtl5000_enable_regulators() Function sgtl5000_enable_regulators() is somehow odd in handling the optional external VDDD supply. The driver can only enable this supply on SGTL5000 chip before revision 0x11, and of course when this external VDDD is present. It currently does something like below. 1. Check if regulator_bulk_get() on VDDA, VDDIO and VDDD will fail. If it fails, VDDD must be absent and it falls on internal LDO by calling sgtl5000_replace_vddd_with_ldo(). Otherwise, VDDD is used. And in either case, regulator_bulk_enable() will be called to enable 3 supplies. 2. In case that SGTL5000 revision is later than 0x11, even if external VDDD is present, it has to roll back the 'enable' and 'get' calls with regulator_bulk_disable() and regulator_bulk_free(), and starts over again by calling sgtl5000_replace_vddd_with_ldo() and regulator_bulk_enable(). Such back and forth calls sequence is complicated and unnecessary. Also, since commit 4ddfebd (regulator: core: Provide a dummy regulator with full constraints), regulator_bulk_get() will always succeeds because of the dummy regulator. Thus the VDDD detection is broken. The patch changes the flow to something like the following, which should be more reasonable and clear, and also fix the VDDD detection breakage. 1. Check if we're running a chip before revision 0x11, on which an external VDDD can possibly be an option. 2. If it is an early revision, call regulator_get_optional() to detect whether an external VDDD supply is available. 3. If external VDDD is present, call sgtl5000_replace_vddd_with_ldo() to update sgtl5000->supplies info. 4. Drop regulator_bulk_get() call in sgtl5000_replace_vddd_with_ldo(), and call it in sgtl5000_enable_regulators() no matter it's an external VDDD or internal LDO. 5. Call regulator_bulk_enable() to enable these 3 regulators. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Signed-off-by: Mark Brown <broonie@linaro.org>

ASoC: sgtl5000: Fix driver probe after reset After a 'reboot' command in Linux or after pressing the system's reset button the sgtl5000 driver fails to probe: sgtl5000 0-000a: Device with ID register ffff is not a sgtl5000 sgtl5000 0-000a: ASoC: failed to probe CODEC -19 imx-sgtl5000 sound.12: ASoC: failed to instantiate card -19 imx-sgtl5000 sound.12: snd_soc_register_card failed (-19) sgtl5000 codec does not have a reset line, nor a reset command in software, so after a system reset the codec does not contain the default register values from sgtl5000_reg_defaults[] anymore, as these are only valid after a power-on-reset cycle. Fix this issue by explicitly reading all the reset register values from sgtl5000_reg_defaults[] and writing them back into sgtl5000 to ensure a sane state.

ASoC: sgtl5000: remove unneeded snd_soc_dapm_new_widgets in probe There's a driver bug that sgtl5000 dapm widget kcontrols do not work. e.g. can not select capture mux with amixer tool(no error info prompted). The root cause is that we still call snd_soc_dapm_new_widgets in codec driver probe function afer converting to table based widgets. This will cause the card dapm widgets are instantiated before the dapm_routes are registered. Then, no available dapm widget pathes can be found during instantiation which finally will cause soc_dapm_mux_update_power to fail(can not find correct path with kcontrol) in snd_soc_dapm_put_enum_double function. Here we remove the unneeded snd_soc_dapm_new_widgets in codec probe and let the soc core to handle the register sequence properly. Then we can fix above issue.

regulator: core: Use a struct to pass in regulator runtime configuration Rather than adding new arguments to regulator_register() every time we want to add a new bit of dynamic information at runtime change the function to take these via a struct. By doing this we avoid needing to do further changes like the recent addition of device tree support which required each regulator driver to be updated to take an additional parameter. The regulator_desc which should (mostly) be static data is still passed separately as most drivers are able to configure this statically at build time.

ASoC: Constify snd_soc_dai_ops structs Commit 1ee46ebd("ASoC: Make the DAI ops constant in the DAI structure") introduced the possibility to have constant DAI ops structures, yet this is barley used in both existing drivers and also new drivers being submitted, although none of them modifies its DAI ops structure. The later is not surprising since existing drivers are often used as templates for new drivers. So this patch just constifies all existing snd_soc_dai_ops structs to eliminate the issue altogether.

ASoC: sgtl5000: fix cache handling Cache handling in this driver is broken. The chip has 16-bit registers, yet the register numbers also increase by 2 per register, i.e. there are only even-numbered registers. The cache in this driver, though, simply increments register numbers, so it does need some mapping as seen in sgtl5000_restore_regs(), note the '>> 1': snd_soc_write(codec, SGTL5000_CHIP_LINREG_CTRL, cache[SGTL5000_CHIP_LINREG_CTRL >> 1]); That, of course, won't work with snd_soc_update_bits(). (Thus, we won't even notice the missing register 0x1c in the default regs which shifted all follwing registers to wrong values.) Noticed on the MX28EVK where enabling the regulators simply locked up the chip. Refactor the routines and use a properly sized default_regs array which matches the register layout of the underlying chip, i.e. create a truly flat cache. This also saves some code which should make up for the bigger array a little. When soc-core will somewhen have another cache type which handles a step size, this conversion will also ease the transition.
