In Chrome OS, a large number of crashes is observed due to corrupted timer
lists. Steven Rostedt pointed out that this usually happens when a timer
is freed while still active, and that the problem is often triggered
by code calling del_timer() instead of del_timer_sync() just before
freeing.
Steven also identified the iwlwifi driver as one of the possible culprits
since it does exactly that.

enable input comes from the CTRLMMR_EPWM_TB_CLKEN register

of 9 clock providers on AM62.

Currently the mpfs clock driver uses a reference clock called the
"msspll", set in the device tree, as the parent for the cpu/axi/ahb
(config) clocks. The frequency of the msspll is determined by the FPGA
bitstream & the bootloader configures the clock to match the bitstream.
The real reference is provided by a 100 or 125 MHz off chip oscillator.
However, the msspll clock is not actually the parent of all clocks on
the system - the reference clock for the rtc/mtimer actually has the
off chip oscillator as its parent.
In order to fix this, add support for reading the configuration of the
msspll & reparent the "config" clocks so that they are derived from
this clock rather than the reference in the device tree.

I made a mistake with the commit a6aaa00324 ("net: ethernet: stmmac:
fix altr_tse_pcs function when using a fixed-link"). I should have
tested against both scenario of having a SGMII interface and one
without.
Without the SGMII PCS TSE adpater, the sgmii_adapter_base address is
NULL, thus a write to this address will fail.

The sequence for IMR boot is essentially the same as normal boot with the
difference that instead of DMA from host the firmware is loaded from IMR.
Re-structure the code to use the existing sequence and also add fallback
handling in case the IMR boot fails.
Introduce a new flag to make the IMR boot support check simpler.

needed. We can instead initialize the NHLT table in the .probe() and
free it in the .remove() callback.

Some boards like the AM335x EVM-SK and AM437x GP EVM provide software
control via a GPIO pin to toggle the DDR VTT regulator to reduce power
consumption in low power states.
The VTT regulator should be disabled after enabling self-refresh on
suspend, and should be enabled before disabling self-refresh on resume.
This is to allow proper self-refresh entry/exit commands to be
transmitted to the memory.
The "ti,vtt-gpio-pin" device tree property in the wkup_m3_ipc node
specifies which GPIO pin to use. This property is communicated to the
Wakeup Cortex M3 co-processor where the actual toggling of the GPIO pin
happens in CM3 firmware [1].
Please note that the GPIO pin must be on the GPIO0 module as that module
is in the wakeup power domain.
