drm: drop _mode_ from drm_mode_connector_attach_encoder

2018-07-13T16:40:27Z

Again to align with the usual prefix of just drm_connector_. Again done with sed + manual fixup for indent issues. Reviewed-by: Sean Paul Signed-off-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20180709084016.23750-7-daniel.vetter@ffwll.ch

drm: drop _mode_ from update_edit_property()

2018-07-13T16:40:27Z

Just makes it longer, and for most things in drm_connector.[hc] we just use the drm_connector_ prefix. Done with sed + a bit of manual fixup for the indenting.

drm/tilcdc: Use drm_connector_has_possible_encoder()

2018-07-05T13:52:08Z

Use drm_connector_has_possible_encoder() for checking whether the encoder has an associated connector. v2: Replace the drm_for_each_connector_encoder_ids() loop with a simple drm_connector_has_possible_encoder() call Cc: Jyri Sarha Cc: Tomi Valkeinen Signed-off-by: Ville Syrjälä Link: https://patchwork.freedesktop.org/patch/msgid/20180628131315.14156-10-ville.syrjala@linux.intel.com Reviewed-by: Alex Deucher Acked-by: Jyri Sarha

drm/tilcdc: Defer probe if there are no connectors

2018-07-05T11:06:22Z

During probe there may not be any connectors yet if e.g. the panel failed or hasn't been probed yet. I hitting this in practice the panels probing was being delayed due to using a gpio backlight. Fix this by returning -EPROBE_DEFER so the probing will be retried. Signed-off-by: Sjoerd Simons Signed-off-by: Jyri Sarha

drm/tilcdc: Fix setting clock divider for omap-l138

2018-05-09T16:55:18Z

This fixes setting the clock divider on the TI OMAP-L138 LCDK board. The clock drivers for OMAP-L138 are being covernted to the common clock framework. When this happens, clk_set_rate() will no longer return an error. However, on this SoC, the clock rate cannot actually be changed because the clock has to maintain a fixed ratio to the ARM clock. So after attempting to set the clock rate, we need to check to see if the new rate is actually close enough. If not, then follow the previous error path to adjust the divider in LCDC IP block to compensate for not being able to change the parent clock rate. Tested working on a TI OMAP-L138 LCDK board.

drm/tilcdc: tilcdc_panel: Rename device from "panel" to "tilcdc-panel"

2018-02-28T09:48:25Z

Rename the bundled tilcdc_panel driver from just "panel" to "tilcdc-panel" to avoid noisy error messages from the driver trying to probe all device nodes named "panel". Signed-off-by: Jyri Sarha Reviewed-by: Tomi Valkeinen

drm/tilcdc: Add support for drm panels

2018-02-28T09:48:16Z

Add support for drm panels to tilcdc. Adding the support on top of the existing bridge support needs only couple of lines of code when using using the drm panel bridge helpers. Signed-off-by: Jyri Sarha Reviewed-by: Tomi Valkeinen

drm/tilcdc: panel: Use common error handling code in of_get_panel_info()

2018-02-28T09:25:36Z

Add a jump target so that a bit of exception handling can be better reused at the end of this function. Signed-off-by: Markus Elfring Signed-off-by: Jyri Sarha
