drm/panel: raydium-rm67200: Move initialization from enable() to prepare stage

2025-08-20T16:36:10Z

[ Upstream commit 691674a282bdbf8f8bce4094369a2d1e4b5645e9 ] The DSI host has different modes in prepare() and enable() functions, prepare() is in LP command mode and enable() is in HS video mode. >From our experience, generally the initialization sequence needs to be sent in the LP command mode. Move the setup init function from enable() to prepare() to fix a display shift on rk3568 evb. Tested on rk3568/rk3576/rk3588 EVB.

drm/panel/sharp-ls043t1le01: Use _multi variants

2025-06-27T10:13:14Z

[ Upstream commit 20e8219205145e1af3b98b6a0a3cc59568116a05 ] Move away from using deprecated API and use _multi variants if available. Use mipi_dsi_msleep() and mipi_dsi_usleep_range() instead of msleep() and usleep_range() respectively. Used Coccinelle to find the _multi variant APIs,replacing mpi_dsi_msleep() where necessary and for returning dsi_ctx.accum_err in these functions. mipi_dsi_dcs_write() does not have a corresponding _multi() variant. Replacing it with mipi_dsi_dcs_write_seq_multi() instead. This change is manual. The Coccinelle script is the same as the one in commit c8ba07caaecc ("drm/panel/synaptics-r63353: Use _multi variants") v2: Use mipi_dsi_write_buffer_multi() in place of mipi_dsi_dcs_write(). (Dmitry) v3: add commit details where the same coccinelle script is used and remove the actual script from commit log.

drm: panel: jd9365da: fix reset signal polarity in unprepare

2025-04-22T07:42:04Z

commit a8972d5a49b4 ("drm: panel: jd9365da-h3: fix reset signal polarity") fixed reset signal polarity in jadard_dsi_probe() and jadard_prepare(). It was not done in jadard_unprepare() because of an incorrect assumption about reset line handling in power off mode. After looking into the datasheet, it now appears that before disabling regulators, the reset line is deasserted first, and if reset_before_power_off_vcioo is true, then the reset line is asserted. Fix reset polarity by inverting gpiod_set_value() second argument in in jadard_unprepare().
