[PATCH v3 00/14] drm/tidss: dispc: Convert to FIELD_* API
Posted by Maxime Ripard 1 month, 1 week ago
Hi,

The tidss driver rolls its own API equivalent to the FIELD_* API already
provided the kernel.

Since it's an ad-hoc implementation, it also is less convenient and
doesn't provide some useful features like being able to share the field
definitions that will come handy in the future.

Thus, this series converts the driver to that API and drops its own
version.

Let me know what you think,
Maxime

This looks good. I'll push to drm-misc-next.
