Jani Nikula 81b55ef1f4 drm/i915: drop a bunch of superfluous inlines
Remove a number of inlines from .c files, and let the compiler decide
what's best. There's more to do, but need to start somewhere, and need
to start setting the example.

Wambui Karuga 6a9cc4bfb7 drm/i915/gmbus: convert to drm_device based logging,
Conversion instances of printk based drm logging macros to use the
struct drm_device based logging macros in i915/display/intel_gmbus.c.
This was done using the following coccinelle semantic patch that
transforms based on the existence of an existing drm_i915_private
device:

Jani Nikula 83d2bdb6a0 drm/i915: significantly reduce the use of <drm/i915_drm.h>
The #include has been splattered all over the place, but there are
precious few places, all .c files, that actually need it.

v2: remove leftover double newlines

Pankaj Bharadiya f4224a4cb1 drm/i915/display: Make WARN* drm specific where drm_device ptr is available
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.

Jani Nikula d9053b237b drm/i915/gmbus: use intel_de_*() functions for register access
The implicit "dev_priv" local variable use has been a long-standing pain
point in the register access macros I915_READ(), I915_WRITE(),
POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW().

Replace them with the corresponding new display engine register
accessors intel_de_read(), intel_de_write(), intel_de_posting_read(),
intel_de_read_fw(), and intel_de_write_fw().

No functional changes.

Jani Nikula a2b69ea4d2 drm/i915: introduce INTEL_DISPLAY_ENABLED()
Prepare for making a distinction between not having display and having
disabled display. Add INTEL_DISPLAY_ENABLED() and use it where
HAS_DISPLAY() is used after intel_device_info_runtime_init(). This is
initially duplication, as disabling display still leads to ->pipe_mask =
0 and HAS_DISPLAY() being false.

Note that ever since i915.display_disable was introduced, it has not
affected PCH detection even if it uses HAS_DISPLAY(), as display disable
happens after that.

Since INTEL_DISPLAY_ENABLED() will not make sense unless HAS_DISPLAY()
is true, include a warning for catching misuses making decisions on
INTEL_DISPLAY_ENABLED() when HAS_DISPLAY() is false.

v2: Remove INTEL_DISPLAY_ENABLED() check from intel_detect_pch() (Chris)

Matt Roper 5a6b7ef69e drm/i915/gen11: Allow usage of all GPIO pins
Our pin mapping tables for ICP and MCC currently only list the standard
GPIO pins used for various output ports.  Even through ICP's standard
pin usage only utilizes pins 1, 2, and 9-12, and MCC's standard pin
usage only uses pins 1, 2, and 9, these platforms do still have GPIO
registers to address pins in the range 1-3 and 9-14.  OEM's may remap
GPIO usage in non-standard ways (and provide the actual mapping via VBT
settings), so we shouldn't exclude pins on these platforms just because
they aren't part of the standard mappings.

TGP's standard pin tables contains all the possible pins, so let's
rename them to "icp" and use them for all PCH >= PCH_ICP.  This will
prevent intel_gmbus_is_valid_pin from rejecting non-standard pin usage
that an OEM specifies via the VBT.

Note that this will cause pin 9 to be labeled as "tc1" instead of "dpc"
in debug messages on platforms with the MCC PCH, but that may actually
help avoid confusion since the text strings will now be the same on all
gen11+ platforms instead of being different on just EHL.

v2: Drop now-unused MCC_DDC_BUS_DDI_* names.

v3: We want to compare against INTEL_PCH_TYPE, not INTEL_PCH_ID.

Jani Nikula 1d455f8de8 drm/i915: rename intel_drv.h to display/intel_display_types.h
Everything about the file is about display, and mostly about types
related to display. Move under display/ as intel_display_types.h to
reflect the facts.

There's still plenty to clean up, but start off with moving the file
where it logically belongs and naming according to contents.

v2: fix the include guard name in the renamed file

Although EHL introduces a new PCH, the South Display part of the PCH

remapped.  Most notably, Port C is mapped to the pins that ICP uses for
TC Port 1.
