drm/panel: type promotion bug in s6e8aa0_read_mtp_id()

2018-09-26T06:36:40+00:00

[ Upstream commit cd0e0ca69109d025b1a1b6609f70682db62138b0 ] The ARRAY_SIZE() macro is type size_t. If s6e8aa0_dcs_read() returns a negative error code, then "ret < ARRAY_SIZE(id)" is false because the negative error code is type promoted to a high positive value.

drm/panel: simple: Fix the bus format for the Ontat panel

2018-05-30T05:50:46+00:00

[ Upstream commit 5651e5e094591f479adad5830ac1bc45196a39b3 ] This fixes bad color output. When I was first testing the device I had the DPI hardware set to 666 mode, but apparently in the refactor to use the bus_format information from the panel driver, I failed to actually update the panel.

drm/panel: simple: Add missing panel_simple_unprepare() calls

2017-12-05T10:24:34+00:00

commit f3621a8eb59a913612c8e6e37d81f16b649f8b6c upstream. During panel removal or system shutdown panel_simple_disable() is called which disables the panel backlight but the panel is still powered due to missing calls to panel_simple_unprepare().

drm/panel: simple: Check against num_timings when setting preferred for timing

2017-01-19T19:18:06+00:00

commit 230c5b44233ff0543c0b5ccf4ff9400057010fbe upstream. In the loop on .timings, we should check .num_timings to see if it's the only mode specified, not .num_modes, which should be used with .modes.

Taking our cue from commit a42f6e3f8f03 ("drm/panel: simple: Add delay timing for Sharp LQ123P1JX31"), let's add timings: .prepare = t1 + t3 .enable = t7 .unprepare = t11 + 12 Without this, the panel may not be given enough time to come up. Signed-off-by: Brian Norris Signed-off-by: Thierry Reding

drm/panel: simple: Add delay timing for Sharp LQ123P1JX31

2016-08-24T14:19:48+00:00

According to page 16 of the Sharp LQ123P1JX31 datasheet, we need to add the missing delay timing. Panel prepare time should be t1 (0.5 to 10 ms) plus t3 (0 to 100 ms), panel enable time should equal to t7 (0 to 50 ms) and panel unprepare time should be t11 (1 to 50 ms) plus t12 (500 ms).
