2025-05-12drm/msm/hdmi: wire in hpd_enable/hpd_disable bridge opsDmitry Baryshkov
The HDMI driver already has msm_hdmi_hpd_enable() and msm_hdmi_hpd_disable() functions. Wire them into the msm_hdmi_bridge_funcs, so that HPD can be enabled and disabled dynamically rather than always having HPD events generation enabled.

In order to simplify the driver even further and to remove the boilerplate code, rewrite the audio interface to use the DRM HDMI Audio framework. Audio InfoFames are controlled centrally via the DRM HDMI framework. Correct InfoFrame data is programmed at the atomic_pre_enable() time (if it was set before, drm_atomic_helper_connector_hdmi_update_infoframes() takes care of writing all InfoFrames, including the Audio one.) or during msm_hdmi_bridge_audio_prepare() when the new stream is started.

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>

2024-01-18drm: remove I2C_CLASS_DDC supportHeiner Kallweit
After removal of the legacy EEPROM driver and I2C_CLASS_DDC support in olpc_dcon there's no i2c client driver left supporting I2C_CLASS_DDC. Class-based device auto-detection is a legacy mechanism and shouldn't be used in new code. So we can remove this class completely now.

2023-09-09drm/msm: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert the msm drm drivers from always returning zero in the remove callback to the void returning variant.

2023-07-21drm: Explicitly include correct DT includesRob Herring
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.
