[rft, PATCH v3 00/15] drm/i915/dsi: 2nd attempt to get rid of IOSF GPIO

DSI code for VBT has a set of ugly GPIO hacks, one of which is direct
talking to GPIO IP behind the actual driver's back. A second attempt
to fix that is here.

If I understood correctly, my approach should work in the similar way as
the current IOSF GPIO.

Hans, I believe you have some devices that use this piece of code,
is it possible to give a test run on (one of) them?

In v3:
- incorporated series by Jani
- incorporated couple of precursor patches by Hans
- added Rb tag for used to be first three patches (Andi)
- rebased on top of the above changes
- fixed indexing for multi-community devices, such as Cherry View

In v2:
- added a few cleanup patches
- reworked to use dynamic GPIO lookup tables
- converted CHV as well

Andy Shevchenko (8):
drm/i915/dsi: Replace while(1) with one with clear exit condition
drm/i915/dsi: Get rid of redundant 'else'
drm/i915/dsi: Replace check with a (missing) MIPI sequence name
drm/i915/dsi: Extract common soc_gpio_set_value() helper
drm/i915/dsi: Replace poking of VLV GPIOs behind the driver's back
drm/i915/dsi: Prepare soc_gpio_set_value() to distinguish GPIO
communities
drm/i915/dsi: Replace poking of CHV GPIOs behind the driver's back
drm/i915/iosf: Drop unused APIs

Hans de Goede (2):
drm/i915/dsi: Remove GPIO lookup table at the end of
intel_dsi_vbt_gpio_init()
drm/i915/dsi: Fix wrong initial value for GPIOs in bxt_exec_gpio()

Jani Nikula (5):
drm/i915/dsi: assume BXT gpio works for non-native GPIO
drm/i915/dsi: switch mipi_exec_gpio() from dev_priv to i915
drm/i915/dsi: clarify GPIO exec sequence
drm/i915/dsi: rename platform specific *_exec_gpio() to
*_gpio_set_value()
drm/i915/dsi: bxt/icl GPIO set value do not need gpio source
