drm/tilcdc: fix leak & null ref in panel_connector_get_modes

2020-08-19T06:14:50+00:00

[ Upstream commit 3f9c1c872cc97875ddc8d63bc9fe6ee13652b933 ] If videomode_from_timings() returns true, the mode allocated with drm_mode_create will be leaked. Also, the return value of drm_mode_create() is never checked, and thus could cause NULL deref. Fix these two issues.

[ Upstream commit 432973fd3a20102840d5f7e61af9f1a03c217a4c ] Register cpufreq notifier after we have initialized the crtc and unregister it before we remove the ctrc. Receiving a cpufreq notify without crtc causes a crash. Reported-by: Peter Ujfalusi Signed-off-by: Jyri Sarha Signed-off-by: Sasha Levin

drm: drop _mode_ from drm_mode_connector_attach_encoder

drm/tilcdc: Defer probe if there are no connectors

2018-07-05T11:06:22+00:00

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

2018-05-09T16:55:18+00:00

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.

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
