Starting BDB version 239, hdr_dpcd_refresh_timeout is introduced to
backlight BDB data. Commit 700034566d ("drm/i915/bios: Define more BDB
contents") updated the backlight BDB data accordingly. This broke the
parsing of backlight BDB data in VBT for versions 236 - 238 (both
inclusive) and hence the backlight controls are not responding on units
with the concerned BDB version.
backlight_control information has been present in backlight BDB data
from at least BDB version 191 onwards, if not before. Hence this patch
extracts the backlight_control information for BDB version 191 or newer.
Tested on Chromebooks using Jasperlake SoC (reports bdb->version = 236).

This reverts commit 8a91b29f1f.
The regulator_disable() added by the original commit solves one kind of
regulator imbalance but adds another one as it allows the regulator to be
disabled one more time than it is enabled in the following scenario:
1. Start video pipeline -> sn65dsi83_atomic_pre_enable -> regulator_enable
2. PLL lock fails -> regulator_disable
3. Stop video pipeline -> sn65dsi83_atomic_disable -> regulator_disable
The reason is clear from the code flow, which looks like this (after
removing unrelated code):
static void sn65dsi83_atomic_pre_enable()
{
regulator_enable(ctx->vcc);
if (PLL failed locking) {
regulator_disable(ctx->vcc); <---- added by patch being reverted
return;
}
}
static void sn65dsi83_atomic_disable()
{
regulator_disable(ctx->vcc);
}
The use case for introducing the additional regulator_disable() was
removing the module for debugging (see link below for the discussion). If
the module is removed after a .atomic_pre_enable, i.e. with an active
pipeline from the DRM point of view, .atomic_disable is not called and thus
the regulator would not be disabled.
According to the discussion however there is no actual use case for
removing the module with an active pipeline, except for
debugging/development.
On the other hand, the occurrence of a PLL lock failure is possible due to
any physical reason (e.g. a temporary hardware failure for electrical
reasons) so handling it gracefully should be supported. As there is no way
for .atomic[_pre]_enable to report an error to the core, the only clean way
to support it is calling regulator_disabled() only in .atomic_disable,
unconditionally, as it was before.

Contrary to i915, in xe ADL-N is kept as a different platform, not a
subplatform of ADL-P. Since the display side doesn't need to
differentiate between P and N, i.e. IS_ALDERLAKE_P_N() is never called,
just fixup the compat header to check for both P and N.
Moving ADL-N to be a subplatform would be more complex as the firmware
loading in xe only handles platforms, not subplatforms, as going forward
the direction is to check on IP version rather than
platforms/subplatforms.

When you create a submenu using the 'menu' syntax, there is no
ambiguity about its end because the code between 'menu' and 'endmenu'
becomes the submenu.
In contrast, 'menuconfig' does not have the corresponding end marker.
Instead, the end of the submenu is inferred from symbol dependencies.
This is detailed in Documentation/kbuild/kconfig-language.rst, starting
line 348. It outlines two methods to place the code under the submenu:
(1) Open an if-block immediately after 'menuconfig', enclosing the
submenu content within it
(2) Add 'depends on' to every symbol intended for the submenu
Many subsystems opt for (1) because it reliably maintains the submenu
structure.
The DRM subsystem adopts (2). The submenu ends when the sequence of
'depends on DRM' breaks. It can be confirmed by running a GUI frontend
such as 'make menuconfig' and visiting the DRM menu:
< > Direct Rendering Manager (XFree86 4.1.0 and higher DRI support) ----
If you toggle this, you will notice most of the DRM-related options
appear below it, not in the submenu.
I highly recommend the approach (1). Obviously, (2) is not reliable,
as the submenu breaks whenever someone forgets to add 'depends on DRM'.
This commit encloses the entire DRM configuration with 'if DRM' and
'endif', except for DRM_PANEL_ORIENTATION_QUIRKS.
Note:
Now, 'depends on DRM' properties inside the if-block are all redundant.
I leave it as follow-up cleanups.

This reverts commit d674858ff9, as helper
code should always be selected by the driver that needs it, for the
convenience of the final user configuring a kernel.
The user who configures a kernel should not need to know which helpers
are needed for the driver he is interested in. Making a driver depend
on helper code means that the user needs to know which helpers to enable
first, which is very user-unfriendly.
