what's best. There's more to do, but need to start somewhere, and need

Convert various instances of the printk based drm logging macros to the
struct drm_device based logging macros in i915/display/intel_dsi_vbt.c.
This also involves extracting the drm_i915_private device from the
intel_dsi type for use in the logging macros.
This converts DRM_DEBUG/DRM_DEBUG_DRIVER to drm_dbg().

drm specific WARN* calls include device information in the
backtrace, so we know what device the warnings originate from.
Covert all the calls of WARN* with device specific drm_WARN*
variants in functions where drm_device or drm_i915_private struct
pointer is readily available.
The conversion was done automatically with below coccinelle semantic
patch. checkpatch errors/warnings are fixed manually.

Remove the i2c_bus_num >= 0 check from the adapter lookup function
as this would prevent ACPI bus number override. This check was mainly
there to return early if the bus number has already been found but we
anyway return in the next line if the slave address does not match.

Parsing the i2c element is mainly done to transfer the payload from the
MIPI sequence block to the relevant slave device. In some cases, the
commands that are part of the payload can be used to turn on the backlight.
This patch is actually a refactored version of this old patch:
https://lists.freedesktop.org/archives/intel-gfx/2014-December/056897.html
In addition to the refactoring, the original patch is augmented by
looking up the i2c bus from ACPI NS instead of relying on the bus number
provided in the VBT.
This patch was tested on Aava Mobile's Inari 10 tablet. It enabled
turning on the backlight by transferring the payload to the device.
v2:
- Add DRM_DEV_ERROR for invalid adapter and failed transfer and also
drop the DRM_DEBUG that existed originally. (Hans)
- Add two gotos instead of one to clean things up properly.
v3:
- Identify the device on which this patch was tested in the commit
message (Ville)

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.

Everything about the file is about display, and mostly about types
related to display. Move under display/ as intel_display_types.h to
