2021-01-25drm/gma500: Get rid of duplicate NULL checksAndy Shevchenko1-12/+6
Since GPIOs are optional we don't need to repeat checks that are done in the GPIO API. Remove them for good. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Acked-by: Patrik Jakobsson <patrik.r.jakobsson@gmail.com> Acked-by: Linus Walleij <linus.walleij@linaro.org>
2021-01-25drm/gma500: Convert to use new SCU IPC APIAndy Shevchenko7-14/+17
Convert the GMA500 driver to use the new SCU IPC API. This allows us to get rid of the duplicate PMC IPC implementation which is now covered in SCU IPC driver.

The main problem with this error handling was that it didn't clean up if i2c_add_numbered_adapter() failed.

Only the following drivers aren't converted: - amdgpu, because of the driver_feature mangling due to virt support. Subsequent patch will address this. - nouveau, because DRIVER_ATOMIC uapi is still not the default on the platforms where it's supported (i.e. again driver_feature mangling) - vc4, again because of driver_feature mangling - qxl, because the ioctl table is somewhere else and moving that is maybe a bit too much, hence the num_ioctls assignment prevents a const driver structure. - arcpgu, because that is stuck behind a pending tiny-fication series from me. - legacy drivers, because legacy requires non-const drm_driver. Note that for armada I also went ahead and made the ioctl array const.

2020-08-19drm: gma500: Convert to GPIO descriptorsLinus Walleij6-29/+49
Finalize he conversion of GMA500 to use only GPIO descriptors. The GPIO look-up-table is associated with the device directly in the GMA500 Medfield chip driver since no explicit platform type device (such as in x86/platform/intel-mid) exists: the GMA500 probes directly from the PCI device. Apparently GPIOs 128 and 34 are used on all of these so just go ahead and register those for resetting the DSI pipes.

2020-05-27drm/gma500: Stop using mode->private_flagsVille Syrjälä2-24/+6
gma500 only uses mode->private_flags to convey the sdvo pixel multiplier from the encoder .mode_fixup() hook to the encoder .mode_set() hook. Those always seems get called as a pair so let's just stuff the pixel multiplier into the encoder itself as there are no state objects we could use in this non-atomic driver. Paves the way for nuking mode->private_flag.

2020-05-19drm/gma500: remove _unlocked suffix in drm_gem_object_put_unlockedEmil Velikov3-5/+5
Spelling out _unlocked for each and every driver is a annoying. Especially if we consider how many drivers, do not know (or need to) about the horror stories involving struct_mutex. Just drop the suffix. It makes the API cleaner. Done via the following script: __from=drm_gem_object_put_unlocked __to=drm_gem_object_put for __file in $(git grep --name-only $__from); do sed -i "s/$__from/$__to/g" $__file; done Cc: Patrik Jakobsson <patrik.r.jakobsson@gmail.com> Cc: David Airlie <airlied@linux.ie> Cc: Daniel Vetter <daniel@ffwll.ch> Signed-off-by: Emil Velikov <emil.velikov@collabora.com> Acked-by: Sam Ravnborg <sam@ravnborg.org> Acked-by: Thomas Zimmermann <tzimmermann@suse.de> Link: https://patchwork.freedesktop.org/patch/msgid/20200515095118.2743122-20-emil.l.velikov@gmail.com
