On Bay Trail devices the MIPI power on/off sequences for DSI LCD panels
do not control the LCD panel- and backlight-enable GPIOs. So far, when
the VBT indicates we should use the SoC for backlight control, we have
been relying on these GPIOs being configured as output and driven high by
the Video BIOS (GOP) when it initializes the panel.
This does not work when the device is booted with a HDMI monitor connected
as then the GOP will initialize the HDMI instead of the panel, leaving the
panel black, even though the i915 driver tries to output an image to it.
Likewise on some device-models when the GOP does not initialize the DSI
panel it also leaves the mux of the PWM0 pin in generic GPIO mode instead
of muxing it to the PWM controller.
This commit makes the DSI code control the SoC GPIOs for panel- and
backlight-enable on BYT, when the VBT indicates the SoC should be used
for backlight control. It also ensures that the PWM0 pin is muxed to the
PWM controller in this case.
This fixes the LCD panel not lighting up on various devices when booted
with a HDMI monitor connected. This has been tested to fix this on the
following devices:

driver
Move the Crystal Cove PMIC panel GPIO lookup-table from
drivers/mfd/intel_soc_pmic_core.c to the i915 driver.
The moved looked-up table is adding a GPIO lookup to the i915 PCI
device and the GPIO subsys allows only one lookup table per device,
The intel_soc_pmic_core.c code only adds lookup-table entries for the
PMIC panel GPIO (as it deals only with the PMIC), but we also need to be
able to access some GPIOs on the SoC itself, which requires entries for
these GPIOs in the lookup-table.
Since the lookup-table is attached to the i915 PCI device it really
should be part of the i915 driver, this will also allow us to extend
it with GPIOs from other sources when necessary.

When the LCD has not been turned on by the firmware/GOP, because e.g. the
device was booted with an external monitor connected over HDMI, we should
not turn on the panel-enable GPIO when we request it.
Turning on the panel-enable GPIO when we request it, means we turn it on
too early in the init-sequence, which causes some panels to not correctly
light up.
This commits adds a panel_is_on parameter to intel_dsi_vbt_gpio_init()
and makes intel_dsi_vbt_gpio_init() set the initial GPIO value accordingly.
This fixes the panel not lighting up on a Thundersoft TST168 tablet when
booted with an external monitor connected over HDMI.
Changes in v2:
- Call intel_dsi_get_hw_state() to check if the panel is on instead of
relying on the current_mode pointer

On some older devices (BYT, CHT) which may use v2 VBT MIPI-sequences,
we need to manually control the panel enable GPIO as v2 sequences do
not do this.
So far we have been carrying the code to do this on BYT/CHT devices
with a Crystal Cove PMIC in vlv_dsi.c, but as this really is a shortcoming
of the VBT MIPI-sequences, intel_dsi_vbt.c is a better place for this,
so move it there.
This is a preparation patch for adding panel-enable and backlight-enable
GPIO support for BYT devices where instead of the PMIC the SoC is used
for backlight control.

Small objects that only occupy a single page are naturally contiguous,
so mark them as such and allow them the special abilities that come with

A more thorough treatment would extend i915_gem_object_pin_map() to
support discontiguous lmem objects, following the example of
ioremap_prot() and use get_vm_area() + remap_io_sg().

without relying on the special header-test-y syntax that was removed in
commit fcbb8461fd23 ("kbuild: remove header compile test").
I excluded some headers from the test coverage. I hope somebody
intrested can take a closer look at them.
Dummy subdir Makefiles can be removed altogether as single target build
use case is now covered by commit 394053f4a4b3 ("kbuild: make single

We use the global device inode, shared amongst all files, and not the
user's device filp to provide the backing storage for the mmap. The
vma->vm_file provides a redundant reference that breaks existing
expected behaviour that closing the user's device fd will release the
resources bound to it, if a mmap persists. (Even without the
vma->vm_file, the mmap will persist past the user's fd as the storage is
bound to the device, i.e. our reference is on the object not file.)

The coarse power gating was disabled as part of commit 2248a28384fe
("drm/i915/gen8+: Add RC6 CTX corruption WA") as a prelude to recover
from the context corruption; the power gating itself has no direct
impact on the RC6 context corruption. However, that recovery scheme was
never implemented due to difficult corner cases, and so we no longer need
to keep the power gating disabled.

Our usual i915 convention is to assume that future platforms will follow
the same behavior as the latest platform of today. The VDBOX/SFC
capabilities described here don't seem like something that should be
specific to TGL, so let's future-proof by making the test apply to all
gen12+ platforms.

A small tweak to flush then invalidate appears to improve the

for transcoder port sync. So in intel_atomic_check() we need to make
sure that we add all the tiles to the modeset and if one of the
tiles needs a full modeset then mark all other tiles for a full modeset.
We also need to force modeset for all synced crtcs after fastset check.

In commit d03b224f4252 ("drm/i915/gt: Apply sanitiization just before
resume") the GT sanitization was pulled into the resume path as we need
to know the backend in order to do a full reset prior to resume.
However, it is still imperative that we scrub existing GPU state before
clobbering in our early setup, so restore a minimal GPU reset at the
start of our init sequence.
