drm/stm: ltdc: Remove unnecessary platform_get_resource() error check

2017-12-19T14:23:45Z

devm_ioremap_resource() already checks if the resource is NULL, so remove the unnecessary platform_get_resource() error check.

drm/stm: ltdc: add a 2nd endpoint

2017-11-07T13:47:39Z

ltdc can have up to 2 endpoints: - dpi external gpios: for rgb panels or external bridge ICs. - dpi internal ios: connected internally to dsi. Note: Refer to the reference manual to know if the dsi is present on your device.

drm/stm: ltdc: remove bridge from driver internal structure

With a call to drm_of_panel_bridge_remove() we could remove the bridge without store it in ldtc internal driver structure.

drm: stm: remove dead code and pointless local lut storage

2017-08-04T09:37:00Z

The redundant fb helper .load_lut is no longer used, and can not work right without also providing the fb helpers .gamma_set and .gamma_get thus rendering the code in this driver suspect.

drm: Plumb modifiers through plane init

2017-08-01T16:50:06Z

This is the plumbing for supporting fb modifiers on planes. Modifiers have already been introduced to some extent, but this series will extend this to allow querying modifiers per plane. Based on this, the client to enable optimal modifications for framebuffers. This patch simply allows the DRM drivers to initialize their list of supported modifiers upon initializing the plane. v2: A minor addition from Daniel v3: * Updated commit message * s/INVALID/DRM_FORMAT_MOD_INVALID (Liviu) * Remove some excess newlines (Liviu) * Update comment for > 64 modifiers (Liviu) v4: Minor comment adjustments (Liviu) v5: Some new platforms added due to rebase v6: Add some missed plane inits (or maybe they're new - who knows at this point) (Daniel) Signed-off-by: Ben Widawsky Reviewed-by: Daniel Stone (v2) Reviewed-by: Liviu Dudau Signed-off-by: Daniel Stone

2017-07-26T13:02:00Z

Use devm_reset_control_get_exclusive to avoid resource leakage (based on patch "Convert drivers to explicit reset API" from Philipp Zabel). Also use platform_get_resource, which is more usual and consistent with platform_get_irq called later.
