2024-12-01Get rid of 'remove_new' relic from platform driver structLinus Torvalds
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 <torvalds@linux-foundation.org>
2023-11-28drm/bridge: imx93-mipi-dsi: Fix a couple of building warningsLiu Ying
Fix a couple of building warnings on used uninitialized 'best_m' and 'best_n' local variables by initializing 'best_m' to zero and 'best_n' to UINT_MAX. This makes compiler happy only. No functional change.

2023-10-16drm/bridge: imx: Add i.MX93 MIPI DSI supportLiu Ying
Freescale i.MX93 SoC embeds a Synopsys Designware MIPI DSI host controller and a Synopsys Designware MIPI DPHY. Some configurations and extensions to them are controlled by i.MX93 media blk-ctrl. Add a DRM bridge for i.MX93 MIPI DSI by using existing DW MIPI DSI bridge helpers and implementing i.MX93 MIPI DSI specific extensions.
