A compatible string takes the form "vendor,model" and may only contain a single comma, so "waveshare,9.0-dsi-touch-b,4lane" and the other 4-lane entries are not valid. Replace them with the "-4lane" suffix already used by the 8.0" and 10.1" a variants. The missing Waveshare 10.1-DSI-TOUCH-E entry is added at the same time. Signed-off-by: Yu Dukai <646689853@qq.com>
…panels Use a single comma in the compatible strings of the 4-lane panels, as required by the DT specification and as already done for the 8.0" and 10.1" a variants. The old strings are not retained as aliases, since a panel is selected through the overlay parameter rather than the compatible string. Signed-off-by: Yu Dukai <646689853@qq.com>
Update the overlay parameters for the 4-lane panels to the "-4lane" form used by the driver and the binding now. The parameter names are left unchanged, so existing configurations keep working. Signed-off-by: Yu Dukai <646689853@qq.com>
Fix the compatible strings of the Waveshare 4-lane DSI panels: a compatible string takes the form "vendor,model" and may only contain a single comma, so the ",4lane" suffix used by this batch is not valid. This addresses the format noted in raspberrypi#7696 (and the batch that introduced it, raspberrypi#6957): waveshare,12.3-dsi-touch-a,4lane -> waveshare,12.3-dsi-touch-a-4lane waveshare,10.1-dsi-touch-b,4lane -> waveshare,10.1-dsi-touch-b-4lane waveshare,10.1-dsi-touch-e,4lane -> waveshare,10.1-dsi-touch-e-4lane waveshare,9.0-dsi-touch-b,4lane -> waveshare,9.0-dsi-touch-b-4lane The "-4lane" form is the one already used by the 8.0" and 10.1" a variants.

string takes the form "vendor,model" and may only contain a single comma, so
the ",4lane" suffix used by this batch is not valid.
