Based on previous 5.10 builds

Adds GPU workaround by setting CMA area to 128 M instead of
320 M that we've used in the past:

The driver turns on temperature compensation while operating
with main input power, however there are environments where having
the temperature compentation enabled while the main power is off
and the RTC is on battery power that would be beneficial.

Give a warning if the RTC has detected either the oscillator
has failed, or the RTC has a complete power failure.

RTCF is cleared on a write of the RTC registers, while the datasheet
gives no clear indication of how an OSCF condition can be cleared.

The embeddedTS microcontroller implementation of the ISL12022 RTC
includes oscillator trim support that is able to tie in to RTC
offsets in Linux. Enable these operations when the driver detects
it is talking to an emulated ISL12022, no effect on a real part.

Preparing to move to a common config file for most of embeddedTS
devices.
Remove i.MX SL/SX support, not needed
Added configuration options needed by Docker
Larger features (e.g. nfsv4) moved to modules to reduce kernel size
Added compressed module support
The TS-TPC-7990 has an inverted interrupt system in order to
allow the touchscreen to wake the device. The CPU pin is expecting
a falling IRQ, but the INT pin on the touchscreen controller must
be set to active high output.

This adds invert-int-output property to the devicetree parsing.
If set, it inverts the INT output from the controller, but the
driver remains configured for active low IRQ.

Add initial support of the i.MX6UL based TS-7553-V2 platform.

Signed-off-by: Kris Bahnsen <kris@embeddedTS.com>
Specifically adds IIO drivers, mono LCD driver, adds SNVS power
key as a builtin for compatibility with `keypad-test` demo in
ts7553v2-utils.git.

The framebuffer console is needed for TPC platforms, it causes
some issues in the TS-7553-V2 that will be resolved later.

Also removes drivers that would never be used, moves a few from
builtin to module, adds some other features/drivers in as a
module for potential future support.

The previous name, DIO_FAULT#, was incorrectly matching a net name
that was not connected to that GPIO pin. Renamed to BREAKER_TRIP
for clarity and consistency with other platforms.

Added GPIO backlight control so it is a part of the actual kernel
control and not a loose GPIO pin.

Using linux-serial-test, there is a strange hangup that I've traced
to inside the read loop where its expecting more data to have been
read. However, manually verifying with strace the count of data
write()s and read()s, result in the same sum.

What is odd, however, is under 6.6, linux-serial-test under the same
flags, seems to run just fine. So I am unsure what is going on and
may need to do some comparisons of strace on 6.6 to see what exactly
is going on.
