On some boards the SoC can use one pin "PMIC_STBY_REQ" to notify th PMIC
about state changes. In this case internal state of PMIC must be
preconfigured for upcomming state change.
It works fine with the current regulator framework, except with the
power-off case.
This patch is providing an optional pm_power_off_prepare handler
which will configure standby state of the PMIC to disable all power lines.
In my power consumption test on RIoTBoard, I got the following results:
power off without this patch: 320 mA
power off with this patch: 2 mA
suspend to ram: 40 mA

The shutdown() callback of i2c client device calls for both scenarios,
power off and reboot the system.
In case of rebooting, the PMIC is configured to power off the power rails
when receiveing the PMIC_STBY_REQ request.
It leads to powering the module down and system hanging while suspending
the system after soft reboot.
Remove the shutdown() callback.

Looks like from the very beginning we were missing a proper pinmuxing
for the active state of the HSIC data pin!

The pins which can be used for an external ethernet PHY are powered by
a sepearte LDO. Currently in the device tree this rail is set to 1.8V,
the default apalis functionality of these pins requires 3.3V so change
to that.
If used with an external PHY in addition to add the PHY to the device also
the rail's voltage needs to be adapted.

It’s a limitation that one cannot use native SPI CS & DMA and have a
continuous CS for the whole transfer. The CS is deasserted after each
word sent.
One can either use DMA and GPIO CS or one can use PIO mode.
With this commit we change from using PIO mode to DMA mode and
change the CS used from the IP provided one to GPIO CS on the same pin.
This sync's the SPI configuration with the i.MX 8X based modules which
already uses DMA with GPIO CS.

commit e33a814e772cdc36436c8c188d8c42d019fda639 upstream.
gcc 10 will default to -fno-common, which causes this error at link
time:
(.text+0x0): multiple definition of `yylloc'; dtc-lexer.lex.o (symbol from plugin):(.text+0x0): first defined here
This is because both dtc-lexer as well as dtc-parser define the same
global symbol yyloc. Before with -fcommon those were merged into one
defintion. The proper solution would be to to mark this as "extern",
however that leads to:
dtc-lexer.l:26:16: error: redundant redeclaration of 'yylloc' [-Werror=redundant-decls]
26 | extern YYLTYPE yylloc;
| ^~~~~~
In file included from dtc-lexer.l:24:
dtc-parser.tab.h:127:16: note: previous declaration of 'yylloc' was here
127 | extern YYLTYPE yylloc;
| ^~~~~~
cc1: all warnings being treated as errors
which means the declaration is completely redundant and can just be
