usb: 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 as 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.

Below is this bit description from RM of iMX8MM "VBUS Valid Comparator Enable: This signal controls the USB OTG PHY VBUS Valid comparator which indicates whether the voltage on the USB_OTG*_VBUS pin is below the VBUS Valid threshold. The VBUS Valid threshold is nominally 4.75V on this USB PHY. The VBUS Valid threshold can be adjusted using the USBNC_OTGn_PHY_CFG1[OTGTUNE0] bit field. Status of the VBUS Valid comparator, when it is enabled, is reported on the USBNC_OTGn_PHY_STATUS[VBUS_VLD] bit. When OTGDISABLE0 (USBNC_USB_OTGx_PHY_CFG2[10])is set to 1'b0 and DRVVBUS0 is set to 1'b1, the Bandgap circuitry and VBUS Valid comparator are powered, even in Suspend or Sleep mode.

usb: chipidea: imx: Fix Battery Charger 1.2 CDP detection i.MX8MM cannot detect certain CDP USB HUBs. usbmisc_imx.c driver is not following CDP timing requirements defined by USB BC 1.2 specification and section 3.2.4 Detection Timing CDP. During Primary Detection the i.MX device should turn on VDP_SRC and IDM_SINK for a minimum of 40ms (TVDPSRC_ON). After a time of TVDPSRC_ON, the i.MX is allowed to check the status of the D- line. Current implementation is waiting between 1ms and 2ms, and certain BC 1.2 complaint USB HUBs cannot be detected. Increase delay to 40ms allowing enough time for primary detection. During secondary detection the i.MX is required to disable VDP_SRC and IDM_SNK, and enable VDM_SRC and IDP_SINK for at least 40ms (TVDMSRC_ON). Current implementation is not disabling VDP_SRC and IDM_SNK, introduce disable sequence in imx7d_charger_secondary_detection() function. VDM_SRC and IDP_SINK should be enabled for at least 40ms (TVDMSRC_ON). Increase delay allowing enough time for detection.

usb: chipidea: imx: support configuring for active low oc signal The status quo on i.MX6 is that if "over-current-active-high" is specified in the device tree this is configured as expected. If the property is missing polarity isn't changed and so the polarity is kept as setup by the bootloader. Reset default is active high, so active low can only be used with help by the bootloader. On i.MX7 it is similar, but there disabling of over current detection has a similar inconsistency. This patch introduces a new property that allows to explicitly configure for active low over current detection and consistently sets this up. In the absence of an explicit configuration the bit is kept as is. On i.MX7 over current detection is used unless disabled in the device tree.

chipidea: usbmisc_imx: Allow USB OTG to work on mx51 The field PLLDIVVALUE of register PHY_CTRL_1 selects the reference clock source for the PHY: 00 = sysclock uses 19.2 MHz 01 = sysclock uses 24 MHz 10 = sysclock uses 26 MHz 11 = sysclock uses 27 MHz The reset value for this field is 10 according to the reference manual, and even though this reset value works for mx53, it does not work for mx51. So instead of relying on the reset value for the PLLDIVVALUE field, explicitly set it to 01 so that a 24MHz clock can be selected for the PHY and allowing both mx51 and mx53 to have USB OTG port functional. Succesfully tested 'g_ether' on a imx51-babbage and on a imx53-qsb boards.

Sascha Hauer <s.hauer@pengutronix.de> |
USB: chipidea: i.MX: simplify usbmisc The chipidea i.MX driver is split into two drivers. The ci_hdrc_imx driver handles the chipidea cores and the usbmisc_imx driver handles the noncore registers common to all chipidea cores (but SoC specific). Current flow is: - usbmisc sets an ops pointer in the ci_hdrc_imx driver during probe - ci_hdrc_imx checks if the pointer is valid during probe, if yes calls the functions in the ops pointer. - usbmisc_imx calls back into the ci_hdrc_imx driver to get additional data This is overly complicated and has problems if the drivers are compiled as modules. In this case the usbmisc_imx driver can be unloaded even if the ci_hdrc_imx driver still needs usbmisc functionality. This patch changes this by letting the ci_hdrc_imx driver calling functions from the usbmisc_imx driver. This way the symbol resolving during module load makes sure the ci_hdrc_imx driver depends on the usbmisc_imx driver. Also instead of letting the usbmisc_imx driver call back into the ci_hdrc_imx driver, pass the needed data in the first place.

Modules with ci13xxx prefix are also renamed accordingly and aliases are added for compatibility. Otherwise, no functional changes.
