Enable PSR on eDP interface using drm self-refresh librabry.
This patch uses a trigger from self-refresh library to enter/exit
into PSR, when there are no updates from framework.

Hi:
fbtft_register_backlight assume backlight is off, get polarity from
current state of pin. but the led gpio is requested by GPIOD_OUT_LOW
flag, which means the gpio state when fbtft_register_backlight is always
low.
Is it a bug?
Thanks
Currently platform_get_irq_byname_optional() returns an error code even
if IRQ resource simply has not been found. It prevents the callers from
being error code agnostic in their error handling:
ret = platform_get_irq_byname_optional(...);
if (ret < 0 && ret != -ENXIO)
Add support for basic panel self refresh (PSR) feature for eDP.
Add a new interface to set PSR state in the sink from DPU.
Program the eDP controller to issue PSR enter and exit SDP to
the sink.

Hi all,
The ongoing merge conflicts between the drm-intel tree and the
drm-intel-gt tree are just a mess, so I am removing the drm-intel-gt
tree from linux-next until you all can come up with a better way of
