The DRM driver most notably, but also out of tree drivers (for now) like
the VPU or GPU drivers, are quite big consumers of large, contiguous memory
buffers. However, the sunxi_defconfig doesn't enable CMA in order to
mitigate that, which makes them almost unusable.
Enable it to make sure it somewhat works.

This branch contains platform updates for 32- and 64-bit ARM,
including defconfig updates to enable new options, drivers and
platforms. There are also a few fixes and cleanups for some existing vendors.
Some of the things worth highlighting here are:
- Enabling new crypt drivers on arm64 defconfig
- QCOM IPQ8074 clocks and pinctrl drivers on arm64 defconfig
- Debug support enabled for Renesas r8a7743
- Various config updates for Renesas platforms (sound, USB, other drivers)
- Platform support (including SMP) for TI dra762
- OMAP cleanups: Move to use generic 8250 debug_ll, removal of stale DMA code

This enables CONFIG_THERMAL_OF by default for sunxi_defconfig. It is
required to get Allwinner SoCs' temperature from the GPADC driver.
The Allwinner SoCs all have an ADC that can also act as a touchscreen
controller and a thermal sensor. The first four channels can be used
either for the ADC or the touchscreen and the fifth channel is used for
the thermal sensor.
The thermal sensor requires the IP to be in touchscreen mode to return
correct values. Therefore, if the user is continuously reading the ADC
channel(s), the thermal framework in which the thermal sensor is
registered will switch the IP in touchscreen mode to get a temperature
value and requires a delay of 100ms (because of the mode switching),
then the ADC will switch back to ADC mode and requires also a delay of
100ms. If the ADC readings are critical to user and the SoC temperature
is not, the GPADC driver is capable of not registering the thermal
sensor in the thermal framework and thus, "quicken" the ADC readings. In
most use cases, the SoC temperature is more critical (for cpu throttling
for example or activating cooling devices) than ADC readings, thus it is
now enabled by default.

As usual, a bunch of commits, mostly adding drivers and other options to

There's an introduction of a pxa_defconfig, since PXA finally will allow
building a shared kernel for all boards. With this, we can hopefully
remove a bunch of individual defconfigs down the road but it requires
a bit of real life testing and transition period.

Commit 69fb4dcada ("power: Add an axp20x-usb-power driver") introduced a new
driver for the USB power supply used on various Allwinner based SBCs. However,
the driver was not added to sunxi_defconfig which breaks USB support for some
boards (e.g. LeMaker BananaPi) as the kernel will now turn off the USB power
supply during boot by default if the driver isn't present. (This was not the
case in linux 4.3 or lower where the USB power was always left on.)
Hence, add the driver to sunxi_defconfig in order to keep USB support working
on those boards that require it.
