At the jt240mhqs_hwt_ek_e3 panel, noticeable flickering occurs. This is
addressed by patch 1, which adjusts the vertical timing. Patch 2 and 3 are
two more minor fixes for timing and dimension.

Use the default timing parameters to get a refresh rate of about 60 Hz for
a clock of 6 MHz.

Flickering was observed when using partial mode. Moving the vsync to the
same position as used by the default sitronix-st7789v timing resolves this
issue.

drm/panel: sitronix-st7789v: fix timing
Hi,
Besides dt-bindings, there has been no feedback on this series yet. How
to proceed?
For clarification: Besides adjusting panel parameters, we need the
panel-timing to add a partial display mode later.
Regards,
Gerald

Parse device tree for panel-timing and allow to override the typical
timing. This requires the timing to be defined as display_timing instead
of drm_display_mode.

Use h/v-sync and pixel clock polarity flags for RGB output. For all other
outputs this is already implemented.
