drm/panel-edp: Add override_edid_mode quirk for generic edp

2024-02-05T20:14:26+00:00

[ Upstream commit 9f7843b515811aea6c56527eb195b622e9c01f12 ] Generic edp gets mode from edid. However, some panels report incorrect mode in this way, resulting in glitches on panel. Introduce a new quirk additional_mode to the generic edid to pick a correct hardcoded mode.

drm/panel: samsung-s6d7aa0: drop DRM_BUS_FLAG_DE_HIGH for lsl080al02

[ Upstream commit 62b143b5ec4a14e1ae0dede5aabaf1832e3b0073 ] It turns out that I had misconfigured the device I was using the panel with; the bus data polarity is not high for this panel, I had to change the config on the display controller's side. Fix the panel config to properly reflect its accurate settings.

drm/panel: st7701: Fix AVCL calculation

2024-01-25T23:35:35+00:00

[ Upstream commit 799825aa87200ade1ba21db853d1c2ff720dcfe0 ] The AVCL register, according to the datasheet, comes in increments of -0.2v between -4.4v (represented by 0x0) to -5.0v (represented by 0x3). The current calculation is done by adding the defined AVCL value in mV to -4400 and then dividing by 200 to get the register value. Unfortunately if I subtract -4400 from -4400 I get -8800, which divided by 200 gives me -44. If I instead subtract -4400 from -4400 I get 0, which divided by 200 gives me 0. Based on the datasheet this is the expected register value.
