2025-05-19drm/nouveau/gsp: split rpc handling out on its ownBen Skeggs
Later patches in the series add HALs around various RM APIs in order to support a newer version of GSP-RM firmware. In order to do this, begin by splitting the code up into "modules" that roughly represent RM's API boundaries so they can be more easily managed. Aside from moving the RPC function pointers, no code change is indended.

2025-05-19drm/nouveau/gsp: remove gsp-specific chid allocation pathBen Skeggs
In order to specify a channel ID to RM during channel allocation, the channel ID is broken down into a "userd page" index and an index into that page. It was assumed that RM would enforce that the same physical block of memory be used for all CHIDs within a "userd page", and the GSP paths override NVKM's normal CHID allocation to handle this. However, none of that turns out to be necessary. Remove the GSP-specific code and use the regular CHID allocation path.

2025-05-19drm/nouveau/gsp: fix rm shutdown wait conditionBen Skeggs
Though the initial upstreamed GSP-RM version in nouveau was 535.113.01, the code was developed against earlier versions. 535.42.02 modified the mailbox value used by GSP-RM to signal shutdown has completed, which was missed at the time. I'm not aware of any issues caused by this, but noticed the bug while working on GB20x support.

This reverts commit 18d7de823b7150344d242c3677e65d68c5271b04. We cannot use vmap_pfn() in vmap_udmabuf() as it would fail the pfn_valid() check in vmap_pfn_apply(). This is because vmap_pfn() is intended to be used for mapping non-struct-page memory such as PCIe BARs.

2025-05-14drm/mediatek: mtk_drm_drv: Unbind secondary mmsys components on errAngeloGioacchino Del Regno
When calling component_bind_all(), if a component that is included in the list fails, all of those that have been successfully bound will be unbound, but this driver has two components lists for two actual devices, as in, each mmsys instance has its own components list. In case mmsys0 (or actually vdosys0) is able to bind all of its components, but the secondary one fails, all of the components of the first are kept bound, while the ones of mmsys1/vdosys1 are correctly cleaned up. This is not right because, in case of a failure, the components are re-bound for all of the mmsys/vdosys instances without caring about the ones that were previously left in a bound state. Fix that by calling component_unbind_all() on all of the previous component masters that succeeded binding all subdevices when any of the other masters errors out.

2025-05-14drm/mediatek: Fix kobject put for component sub-driversAngeloGioacchino Del Regno
In function mtk_drm_get_all_drm_priv(), this driver is incrementing the refcount for the sub-drivers of mediatek-drm with a call to device_find_child() when taking a reference to all of those child devices. When the component bind fails multiple times this results in a refcount_t overflow, as the reference count is never decremented: fix that by adding a call to put_device() for all of the mmsys devices in a loop, in error cases of mtk_drm_bind() and in the mtk_drm_unbind() callback.
