2020-04-28drm/komeda: use devm_drm_dev_allocDaniel Vetter
Komeda uses the component framework, which does open/close a new devres group around all the bind callbacks. Which means we can use devm_ functions for managing the drm_device cleanup, with leaking stuff in case of deferred probes or other reasons to unbind components, or the component_master. Also note that this fixes a double-free in the probe unroll code, bot drm_dev_put and kfree(kms) result in the kms allocation getting freed. Aside: komeda_bind could be cleaned up a lot, devm_kfree is a bit redundant. Plus I'm not clear on why there's suballocations for mdrv->mdev and mdrv->kms. Plus I'm not sure the lifetimes are correct with all that devm_kzalloc usage ... That structure layout is also the reason why komeda still uses drm_device->dev_private and can't easily be replaced with a proper container_of upcasting. I'm pretty sure that there's endless amounts of hotunplug/hotremove bugs in there with all the unprotected dereferencing of drm_device->dev_private.

2020-03-18drm: convert .debugfs_init() hook to return void.Wambui Karuga
As a result of commit 987d65d01356 (drm: debugfs: make drm_debugfs_create_files() never fail) and changes to various debugfs functions in drm/core and across various drivers, there is no need for the drm_driver.debugfs_init() hook to have a return value. Therefore, declare it as void. This also includes refactoring all users of the .debugfs_init() hook to return void across the subsystem. v2: include changes to the hook and drivers that use it in one patch to prevent driver breakage and enable individual successful compilation of this change.

2020-03-18drm/arm: make hdlcd_debugfs_init() return 0Wambui Karuga
Since commit 987d65d01356 (drm: debugfs: make drm_debugfs_create_files() never fail), drm_debugfs_create_files() never fails and should return void. Therefore, remove its use as the return value of hdlcd_debugfs_init() and have the latter function return 0 directly. v2: make hdlcd_debugfs_init() return 0 instead of void to ensure that each patch compiles individually.

2019-10-01drm/komeda: Workaround for broken FLIP_COMPLETE timestampsMihail Atanassov
When initially turning a crtc on, drm_reset_vblank_timestamp will set the vblank timestamp to 0 for any driver that doesn't provide a ->get_vblank_timestamp() hook. Unfortunately, the FLIP_COMPLETE event depends on that timestamp, and the only way to regenerate a valid one is to have vblank interrupts enabled and have a valid in-ISR call to drm_crtc_handle_vblank. Additionally, if the user doesn't request vblanks but _does_ request FLIP_COMPLETE events, we still don't have a good timestamp: it'll be the same stamp as the last vblank one. Work around the issue by always enabling vblanks when the CRTC is on. Reducing the amount of time that PL0 has to be unmasked would be nice to fix at a later time.

2019-09-27drm/komeda: SW workaround for D71 doesn't flush shadow registersLowry Li (Arm Technology China)
This is a SW workaround for shadow un-flushed when together with the DOU Timing-disable. D71 HW doesn't update shadow registers when display output is turned off. So when we disable all pipeline components together with display output disabling by one flush or one operation, the disable operation updated registers will not be flushed or valid in HW, which may lead problem. To workaround this problem, introduce a two phase disable for pipeline disable. Phase1: Disable components with display is on and flush it, this phase for flushing or validating the shadow registers. Phase2: Turn-off display output.
