Get rid of 'remove_new' relic from platform driver struct

2024-12-01T23:12:43+00:00

The continual trickle of small conversion patches is grating on me, and
is really not helping.  Just get rid of the 'remove_new' member
function, which is just an alias for the plain 'remove', and had a
comment to that effect:

  /*
   * .remove_new() is a relic from a prototype conversion of .remove().
   * New drivers are supposed to implement .remove(). Once all drivers are
   * converted to not use .remove_new any more, it will be dropped.
   */

This was just a tree-wide 'sed' script that replaced '.remove_new' with
'.remove', with some care taken to turn a subsequent tab into two tabs
to make things line up.

I did do some minimal manual whitespace adjustment for places that used
spaces to line things up.

Then I just removed the old (sic) .remove_new member function, and this
is the end result.  No more unnecessary conversion noise.

drm/imx/dcss: include drm/drm_bridge.h header

2024-11-01T03:46:25+00:00

Compile-testing random configurations leads to failures in
dcss-kms.c from a missing declaration:

drivers/gpu/drm/imx/dcss/dcss-kms.c:95:8: error: use of undeclared identifier 'drm_bridge_attach'
   95 |         ret = drm_bridge_attach(encoder, bridge, NULL,

   96 |                                 DRM_BRIDGE_ATTACH_NO_CONNECTOR);
      |                                 ^

Include the header directly.

drm/imx/dcss: Allow build with COMPILE_TEST=y

2024-10-25T07:23:55+00:00

Allow imx/dcss to be built with COMPILE_TEST=y for greater
coverage. Builds fine on x86/x86_64 at least.

drm/imx: parallel-display: add legacy bridge Kconfig dependency

2024-10-22T13:37:19+00:00

The driver now uses the legacy bridge helper code but can be configured
to get built without it:

ERROR: modpost: "devm_imx_drm_legacy_bridge" [drivers/gpu/drm/imx/ipuv3/parallel-display.ko] undefined!

Add the required dependency, same as in the ldb driver.

The dcss driver specifies a preferred color mode of 32. As this
