inux device was set up. This tied OF framebuffers to offb and makes writing other drivers for the OF framebuffers complicated. The absence of a Linux device further prevented real hot-unplugging. Adding a distinct platform device for each OF framebuffer solves both problems. Specifically, a DRM driver can now provide graphics output for modern userspace. Some of the offb init code is now located in the OF initialization. There's now also an implementation of of_platform_default_populate_init(), which was missing before. The OF side creates different devices for either OF display nodes or BootX displays as they require different handling by the driver. The offb drivers picks up each type of device and runs the appropriate fbdev initialization. Tested with OF display nodes on qemu's ppc64le target. v3: * declare variable 'node' with function scope (Rob) v2: * run PPC code as part of existing initialization (Rob) * add a few more error warnings (Javier) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Reviewed-by: Rob Herring <robh@kernel.org> Link: https://patchwork.freedesktop.org/patch/msgid/20220419100405.12600-2-tzimmermann@suse.de 2022-04-20drm/gma500: fix a potential repeat execution in psb_driver_loadXiaomeng Tong1-3/+2 Instead of exiting the loop as expected when an entry is found, the list_for_each_entry() continues until the traversal is complete.

R. A. Prado2-8/+8 As defined in the anx7625 dt-binding, the analogix,lane0-swing and analogix,lane1-swing properties are uint8 arrays. Yet, the driver was reading the array as if it were of uint32 and masking to 8-bit before writing to the registers. This means that a devicetree written in accordance to the dt-binding would have its values incorrectly parsed. Fix the issue by reading the array as uint8 and storing them as uint8 internally, so that we can also drop the masking when writing the registers.

This chip is highly capable at converting formats, but sadly it is also highly undocumented. This driver is written without any documentation from Lontium and based only on shreds of information available in various obscure example codes, hence long runs of unknown register patches and lengthy delays in various places. Whichever register meaning could be divined from its behavior has at least a comment around it. Currently the only mode tested is Single-link DSI to Single-link LVDS. Dual-link LVDS might work as well, the register programming is in place, but is untested.
