I just realised that this and the select_subconnector property isn't
used by any drivers. Do you plan to use them? Maybe they don't need to
be wired up at all.

Hi drm-misc maintainers,
I don't know who has act on this but the driver came through
drm-misc-next so it's most likely not amd.

Hi,
This patchset adds a driver that will work with most MIPI DBI compatible
SPI panels out there.
One change this time: Fix indentation in the DT binding.
All patches are reviewed now so I will apply this after Rob's bot have
looked at the binding.
Thanks for reviewing!
Noralf.

devm_drm_dev_alloc() can't allocate structures that embed a structure
which then again embeds drm_device. Workaround this by adding a
driver_private pointer to struct mipi_dbi_dev which the driver can use for
its additional state.

It aims to use one driver to cover a
devm_drm_dev_alloc() can't allocate structures that embed a structure
which then again embeds drm_device. Workaround this by adding a
driver_private pointer to struct mipi_dbi_dev which the driver can use for

le32_to_cpu() was put around the wrong operand in the descriptor magic
value check. Fix this and put it around the descriptor value which is the
one that is in little endian format.

Add support for initializing the controller from device properties when
the compatible is "sitronix,st7735r".
The rotation property does not apply in this case since a matching
ADDRESS_MODE/madctl value is necessary.

7fb.yaml binding in describing the attached panel. That
binding prefixes the properties with the vendor name, not sure why that
is and I think it looks strange so I try without it.
