Hi,
This series adds PM support for SAMA7G5. The standby, ulp0, ulp1, and
backup modes are supported.
Thank you,
Claudiu Beznea
Changes in v3:
- drop: status = "okay" in patch 16/24
Changes in v2:
- keep only the generic sama7_dt in patch 22/24 and adapt patch 23/24
- collected tags

The switch to the atomic API goes hand in hand with a few fixes to
previously experienced issues:
- The duty cycle is no longer lost after disable/enable (previously the

Implement .get_state to read-out the current hardware state.
The hardware readout may return slightly different values than those
that were set in apply due to the limited range of possible prescale and
counter register values.
Also note that although the datasheet mentions 200 Hz as default

The chip does not come out of POR in active state but in sleep state.
To be sure (in case the bootloader woke it up) we force it to sleep in
probe.
If runtime PM is disabled, we instead wake the chip in .probe and put it
to sleep in .remove.

If the flag PWM_USAGE_POWER is set on a channel, the PWM driver may
optimize the signal as long as the power output is not changed.
Depending on the specific driver, the optimization could for example
improve EMI (if supported) by phase-shifting the individual channels.

If PWM_USAGE_POWER is set on a PWM, the pca9685 driver will phase shift
the individual channels relative to their channel number. This improves
EMI because the enabled channels no longer turn on at the same time,
while still maintaining the configured duty cycle / power output.

Previously, the last used PWM channel could change the global prescale
setting, even if other channels are already in use.
Fix it by only allowing the first enabled PWM to change the global
chip-wide prescale setting. If there is more than one channel in use,
the prescale settings resulting from t
Regmap operations can fail if the underlying subsystem is not working
properly (e.g. hogged I2C bus, etc.)
As this is useful information for the user, print an error message if it
happens.
Let probe fail if the first regmap_read or the first regmap_write fails.
