Remove try_vesa_interface. This is because we now make VESA Interface
as a fallback mechanism for Panels which needs VESA DPCD AUX backlight
mechanism to work but have a broken VBT indicating otherwise.
While at in sneak in a small comment cleanup too.
Closes: https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/15679

I think lets start with the problem:
- some panels need VESA DPCD Aux backlight but VBT says otherwise
- we try with Intel backlight interface first, then check for
try_vesa_interface flag before trying VESA backlight interface
-this causes blankout on such panels as try_vesa_interface is not set
and VESA backlight is not tried.
- remove try_vesa_interface flag and lets attempt VESA backlight
interface as a fallback mechansim.

This broke the backlight on my VLV chromebook.

Hi Ville can you provide the full logs from boot with debug set to 0x10e and also when you manipulate your backlight
I did have a commit that checks if vesa is actually possible because some panels report vesa support even though they really cannot
0fb03890d182 drm/i915/backlight: Check if VESA backlight is possible
Also what would be the edp Panel model I can try replicate this issue locally after I find a vlv machine

Hi Ville,
Never mind I found the actual issue, slight oversight by me thanks for bringing this to my attention
Went through the eDP spec again
So apparently if we are only relying only on BACKLIGHT_BRIGHTNESS_AUX_SET_CAPABLE
BACKLIGHT_AUX_ENABLE_CAPABLE should also be set. The only case where one is independent of the other
Is when we are using BL_ENABLE bit in which case the brightness is a production function of the level and pwm level.
Let me float a patch.

Just a heads up: I ran into some devices that don't auto select the intel
interface and don't work with the vesa interface, but ran in the return -ENODEV
case before and then still had a working backlight. This patch stops backlight
control working on these devices. So there seems to be another fallback that
this patch overwrites?
Explicitly forcing the intel interface via module property makes the backlight
control work again.
I will do some more research and then write a proper bug report, but just to let
you know that this patch will cause a regression bug in its current form.
Best regards,
Werner

There have been fixes to get this issue resolved. And they are merged. Should be available on latest upstream drm-tip
