Get rid of 'remove_new' relic from platform driver struct

2024-12-01T23:12:43Z

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. Signed-off-by: Linus Torvalds

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

drm/imx/dcss: Run DRM default client setup

2024-09-26T06:28:02Z

Call drm_client_setup() to run the kernel's default client setup for DRM. Set fbdev_probe in struct drm_driver, so that the client setup can start the common fbdev client. The dcss driver specifies a preferred color mode of 32. As this is the default if no format has been given, leave it out entirely. v5: - select DRM_CLIENT_SELECTION Signed-off-by: Thomas Zimmermann Cc: Laurentiu Palcu Cc: Lucas Stach Cc: Shawn Guo Cc: Sascha Hauer Cc: Pengutronix Kernel Team Cc: Fabio Estevam Acked-by: Javier Martinez Canillas Link: https://patchwork.freedesktop.org/patch/msgid/20240924071734.98201-20-tzimmermann@suse.de

drm_bridge_connector is a "leaf" driver, belonging to the display helper, rather than the "CRTC" drm_kms_helper module. Move the driver to the drm/display and add necessary Kconfig selection clauses.

drm/imx/dcss: fix resource size calculation

2024-02-28T09:16:59Z

The resource is inclusive of the ->start and ->end addresses so this calculation is not correct. It should be "res->end - res->start + 1". Use the resource_size() to do the calculation.

drm/imx/dcss: have all init functions use devres

2024-02-02T13:36:21Z

dcss currently allocates and ioremaps quite a few resources in its probe function's call graph. Devres now provides convenient functions which perform the same task but do the cleanup automatically. Port all memory allocations and ioremap() calls to the devres counterparts.
