Unbreak BCM2835/RPI-B support by bringing it in line with stable/11 and
head:
- Optimise reading of pending interrupt registers.
- Fix a bug where some DTS layouts could cause the premature ending of the
search (i.e. without returning any result) and you would end up with a
random MAC address.
- Reduce the diff between head and arm_intrng with the bcm2835 interrupt
controller.
- Allow the retrieving of the reserved pins state.
- Add support to the bcm2835 mailbox driver to work before interrupts are
enabled. This will be needed to enable the power on devices early on in the
boot process.
- Add support for enabling the USB on the Raspberry Pi boards when it hasn't
been done by U-Boot. This allows the USB to work when we load the kernel
directly.
- Call config_intrhook_disestablish on failure of the bcm2835 fb and fbd intr
hooks. With this we can get through the boot even if these functions fail.
- Add the structures needed to get/set the power state. These can be used
when, for example, we boot without U-Boot and wish to enable USB, or to
suspend an unneeded device.
- Add a mask to match only the relative base address of BSC controllers.
- Move the code to set the device power to the bcm2835 mailbox driver so it
can be reused by other drivers.
- Add the SOC_BCM2835 and SOC_BCM2836 options for the arm kernel and add the
former to std.bcm2835.
- Add a helper function to read clock frequencies from videocore and use this
to get the default frequency of the sdhci device.
- Add partial support for the Raspberry Pi 2.
- Remove a debug #error from the bcm2835 sdhci driver.
- Fetch the SDHCI frequency from videocore (our prefered source) and only if
it fails, fetch the clock-frequency from DTB. If both methods fail, use the
hardcoded default.
- Pass the supplied buffer length instead of a fixed size.
- Add the routines to query and setup the framebuffer state using the
BCM2835_MBOX_CHAN_PROP channel. The old channel (BCM2835_MBOX_CHAN_FB)
seems deprecated on recent firmware versions and is causing a freeze on
RPi 2.
- Fix DMA on RPi 2. BCM2836 has a different base address for peripherals.
- Enable DMA for sdhci on RPi 2 (BCM2836).
- Add a missing wakeup when releasing ownership of the SPI hardware.
- Fix framebuffer compatibility with new RPi firmware.
- Refactor bcm2835_cpufreq to use bcm2835_mbox_property API.
- Fix the sc(4) framebuffer driver on RPi 2.
- Fix the vt(4) framebuffer driver on RPi 2.
- Remove unused mutex and softc variables.
- Refactor mailbox property API to make it usable for /dev/vcio driver.
- Replace semaphore-base locking with sleep/wait synchronization.
- Fix infinite loop if response from VideoCore never received.
- Set have_message in interrupt to handle "response before READ" case.
- Serialize access to property channel when using bcm2835_mbox_property.
- Force framebuffer virtual viewport to be the same as physical.
- Use proper type of tag in bcm2835_mbox_fb_init.
- bcm2835_cpufreq: Only attach driver if we correcly match on the machine
compatible string.
- Add dev.fb.X.resync sysctl to resync ARM framebuffer with VideoCore.
- Do not use DMA channels used by GPU.
- Define local-intc for BCM2836 platform (RPI2) and make BCM2835 intc
a child of it.
- Fix build for Pi kernels with syscons enabled.
- Use VM_MEMATTR_WRITE_COMBINING memattr for mmap(2) on framebuffer.
- Make intc driver compatible with upstream DTS.
- Make Rapsberry Pi watchdog driver compatible with upstream DTS.
- Make sure intc is attached before interrupt consumers.
- Make framebuffer driver compatible with upstream DT.
- Add one more heuristic to determine MAC address of the SMSC device.
- Add compatibility strings from upstream DT.
- Fix spelling mistake, BCM2835_PASWORD -> BCM2835_PASSWORD.
