2020-08-21drm: panel: simple: Fix bpc for LG LB070WV8 panelLaurent Pinchart
[ Upstream commit a6ae2fe5c9f9fd355a48fb7d21c863e5b20d6c9c ] The LG LB070WV8 panel incorrectly reports a 16 bits per component value, while the panel uses 8 bits per component. Fix it.

[ Upstream commit cd0e0ca69109d025b1a1b6609f70682db62138b0 ] The ARRAY_SIZE() macro is type size_t.

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().

The bus format both specifies the bpc and the way the individual bits get serialized into the 7 LVDS timeslots. While the is only one standard mapping for 6 bpc and so the driver could infer the bit mapping from the bpc alone, there are more options for the 8 bpc case which makes specifiying the bus format mandatory. To keep things consistent across panels and to set a precedent for new panel additions add the proper bus format.

2015-01-28drm/panel: sharp: lq101r1sx01: Respect power timingsThierry Reding
Before shutting down the display using the DCS display_off command, wait for 4 frames according to the datasheet. Furthermore, after enabling the power supply, the supply voltage needs around 10 ms to settle. After that, another 120 ms is required before a DCS exit_sleep_mode command can be sent. While at it, no longer send the DCS soft_reset command. This is totally unnecessary because we've just powered up the display, hence it will be in a reset state already.

2014-11-13drm/dsi: Make mipi_dsi_dcs_{read,write}() symmetricalThierry Reding
Currently the mipi_dsi_dcs_write() function requires the DCS command byte to be embedded within the write buffer whereas mipi_dsi_dcs_read() has a separate parameter. Make them more symmetrical by adding an extra command parameter to mipi_dsi_dcs_write(). The S6E8AA0 driver relies on the old asymmetric API and there's concern that moving to the new API may be less efficient.
