Unfortunately the SD card power rail VGEN3 got disabled upon boot which
is reported as follows:
VGEN3: disabling
Subsequent SD card operation fails as follows:
mmcblk1: error -110 sending status command, aborting
This commit fixes this by making sure VGEN3 is always powered and
optionally allows that rail to be automatically switched to 1.8 volts
for proper UHS-I operation potentially massively increasing speeds.

Use the RTS(CTS) output to control a RS485 transmitter.
The UART obviously needs RTS/CTS enabled for this to work, e.g.
fsl,uart-has-rtscts must be present in the device tree.
Enable RS485 by either using ioctrl TIOCSRS485 or enable it in
the device tree by setting linux,rs485-enabled-at-boot-time.
e.g.
&uart2 {
status = "okay";
linux,rs485-enabled-at-boot-time;
};

commit 95272c29378ee7dc15f43fa2758cb28a5913a06d upstream.
-ftracer can duplicate asm blocks causing compilation to fail in
noclone functions. For example, KVM declares a global variable
in an asm like
asm("2: ... \n
.pushsection data \n
.global vmx_return \n
vmx_return: .long 2b");
and -ftracer causes a double declaration.

If a valid power regulator or a dummy regulator is used (which
happens to be the case when no regulator is specified), restart_work
is queued no matter whether the device was running or not at suspend
time. Since work queues get initialized in the ndo_open callback,
resuming leads to a NULL pointer exception.
Reverse exactly the steps executed at suspend time:
- Enable the power regulator in any case
- Enable the transceiver regulator if the device was running, even in
case we have a power regulator
- Queue restart_work only in case the device was running

Make provision for a decoder driver to specify clock mode for
progressive in case the decoder provides deinterlaced output.
This is required for ADV7280 decoder where we can use the hardware
deinterlace capabity of ADV7280. Without setting the clock mode
to progressive but having hardware deinterlace on for ADV7280
results in a non working setup.

The main i.MX 7 SoC compatible string is fsl,imx7d. By that compatible
string, the whole machine init in mach-imx7d.c is registered. While
some might not be necessary for i.MX 7Solo (e.g. SMP init), it seems
not to hurt. On the other hand, not using the i.MX 7 machine init
bypasses a lot of low level init such as PM or basic ethernet clocking.
So far it seemed not to have caused negative effects (likely since the
bootloader initialized those stuff already reasonable...).

Commit 619c5719cf ("MLK-11566-7 ARM: imx: support single SOC config")
ifdef'd clock functionality for SoloX only if Cortex-M4 is running.
However, i.MX 7 also provides a Cortex-M4, hence the true branch in
those if statements have been taken. Since the whole block was ifdef'd,
the functions were rendered useless for i.MX 7. Fix this by just
doing the same thing as if Cortex-M4 is not running.

If poweroff takes a bit more time (e.g. due to I2C call), it is
quite likely that another timer interrupt fires. Timer interrupt
get broadcasted through the timer interrupt callback
tick_handle_oneshot_broadcast. This code broadcasts the timer
interrupt to all CPU's in tick_broadcast_oneshot_mask. The only
function which removes CPU from this mask is
tick_shutdown_broadcast_oneshot which ultimately get called by
_cpu_down (in kernel/cpu.c). The function disable_nonboot_cpus
makes sure that the CPU's get properly taken down and _cpu_down
gets called. With that no more broadcasts are sent to CPU's which
are no longer online.

The Colibri iMX7 uses the SNVS_PMIC_ON_REQ signal (connected to the
PMIC's PMIC_ON_EXTIN GPIO) to power off the module. The SNVS RTC
driver provides a poweroff callback which causes that signal to
go low. However, the current PMIC driver registers a poweroff
callback earlier and therefor the kernel uses the PMIC poweroff
instead of the SNVS RTC poweroff callback.
