drm/panel-elida-kd35t133: hold panel in reset for unprepare For devices like the Anbernic RG351M and RG351P the panel is wired to an always on regulator. When the device suspends and wakes up, there are some slight artifacts on the screen that go away over time. If instead we hold the panel in reset status after it is unprepared, this does not happen.

drm/mipi-dsi: Make remove callback return void 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.

drm/panel: kd35t133: allow using non-continuous dsi clock The panel is able to work when dsi clock is non-continuous, thus the system power consumption can be reduced using such feature. Add MIPI_DSI_CLOCK_NON_CONTINUOUS to panel's mode_flags. Also the flag actually becomes necessary after commit c6d94e37bdbb ("drm/bridge/synopsys: dsi: add support for non-continuous HS clock") and without it the panel only emits stripes instead of output.

drm/panel: use mipi_dsi_dcs_write_buffer where possible A few of the new panels create a local macro wrapping around mipi_dsi_dcs_write. At the same time, they don't really care about the command/payload split. mipi_dsi_dcs_write does a kmalloc/memcpy/kfree for payload > 7 bytes. Avoid that all together by using the _buffer function. Aside: panel-xinpeng-xpp055c272.c calls its wrapper "generic" although it should be "dcs". But that for another day/patch.
