2023-06-29drm/panel: Fine tune Starry-ili9882t panel HFP and HBPCong Yang
Because the setting of hporch is too small, there will be warning in kernel log[1]. After fine tune the HFP and HBP, this warning can be solved. The actual measurement frame rate is 60.1Hz.

2023-05-16drm/panel: Modify innolux hj110iz panel initial codeCong Yang
There is a problem of screen shake on the old panel. So increase the panel GOP component pull-down circuit size in hardware, and update the initialization code at the same time. The new initialization code mainly modifles the following. a)adjusted for GOP timing. When Display sleep in, raise all GOP signals to VGHO and then drop to GND. b)Increased the Vertical back Porch and Vertical pulse width, so need to update vsync_end and vtotal and CLK in drm_display_mode.

2023-01-31drm/panel: boe-tv101wum-nl6: Ensure DSI writes succeed during disableStephen Boyd
The unprepare sequence has started to fail after moving to panel bridge code in the msm drm driver (commit 007ac0262b0d ("drm/msm/dsi: switch to DRM_PANEL_BRIDGE")). You'll see messages like this in the kernel logs: panel-boe-tv101wum-nl6 ae94000.dsi.0: failed to set panel off: -22 This is because boe_panel_enter_sleep_mode() needs an operating DSI link to set the panel into sleep mode. Performing those writes in the unprepare phase of bridge ops is too late, because the link has already been torn down by the DSI controller in post_disable, i.e. the PHY has been disabled, etc. See dsi_mgr_bridge_post_disable() for more details on the DSI . Split the unprepare function into a disable part and an unprepare part. For now, just the DSI writes to enter sleep mode are put in the disable function. This fixes the panel off routine and keeps the panel happy. My Wormdingler has an integrated touchscreen that stops responding to touch if the panel is only half disabled too. This patch fixes it. And finally, this saves power when the screen is off because without this fix the regulators for the panel are left enabled when nothing is being displayed on the screen.

2022-07-09drm/mipi-dsi: Make remove callback return voidUwe Kleine-König
All implementations return 0 and the return value of mipi_dsi_drv_remove() is ignored anyhow. So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour.
