2022-05-04drm/rockchip: Add VOP2 driverAndy Yan9-1/+3493
The VOP2 unit is found on Rockchip SoCs beginning with rk3566/rk3568. It replaces the VOP unit found in the older Rockchip SoCs. This driver has been derived from the downstream Rockchip Kernel and heavily modified: - All nonstandard DRM properties have been removed - dropped struct vop2_plane_state and pass around less data between functions - Dropped all DRM_FORMAT_* not known on upstream - rework register access to get rid of excessively used macros - Drop all waiting for framesyncs The driver is tested with HDMI and MIPI-DSI display on a RK3568-EVB board. Overlay support is tested with the modetest utility. AFBC support on the cluster windows is tested with weston-simple-dmabuf-egl on weston using the (yet to be upstreamed) panfrost driver support.

2022-05-04block: null_blk: Improve device creation with configfsDamien Le Moal1-1/+27
Currently, the directory name used to create a nullb device through sysfs is not used as the device name, potentially causing headaches for users if devices are already created through the modprobe operation withe the nr_device module parameter not set to 0. E.g. a user can do "mkdir /sys/kernel/config/nullb/nullb0" to create a nullb device even though /dev/nullb0 was already created by modprobe. In this case, the configfs nullb device will be named nullb1, causing confusion for the user. Simplify this by using the configfs directory name as the nullb device name, always, unless another nullb device is already using the same name. E.g. if modprobe created nullb0, then: $ mkdir /sys/kernel/config/nullb/nullb0 mkdir: cannot create directory '/sys/kernel/config/nullb/nullb0': File exists will be reported to the user. To implement this, the function null_find_dev_by_name() is added to check for the existence of a nullb device with the name used for a new configfs device directory. nullb_group_make_item() uses this new function to check if the directory name can be used as the disk name. Finally, null_add_dev() is modified to use the device config item name as the disk name for a new nullb device created using configfs. The naming of devices created though modprobe remains unchanged. Of note is that it is possible for a user to create through configfs a nullb device with the same name as an existing device. E.g. $ mkdir /sys/kernel/config/nullb/null will successfully create the nullb device named "null" but this block device will however not appear under /dev/ since /dev/null already exists.
