2024-09-11drm/amd/display: Add all planes on CRTC to state for overlay cursorLeo Li1-0/+11
[Why] DC has a special commit path for native cursor, which use the built-in cursor pipe within DCN planes. This update path does not require all enabled planes to be added to the list of surface updates sent to DC. This is not the case for overlay cursor; it uses the same path as MPO commits. This update path requires all enabled planes to be added to the list of surface updates sent to DC. Otherwise, DC will disable planes not inside the list. [How] If overlay cursor is needed, add all planes on the same CRTC as this cursor to the atomic state. This is already done for non-cursor planes (MPO), just before the added lines.

2024-09-11regulator: core: fix the broken behavior of regulator_dev_lookup()Wei Fang1-0/+3
The behavior of regulator_dev_lookup() for non-DT way has been broken since the commit b8c325545714 ("regulator: Move OF-specific regulator lookup code to of_regulator.c"). Before the commit, of_get_regulator() was used to get the regulator, which returns NULL if the regulator is not found. So the regulator will be looked up through regulator_lookup_by_name() if no matching regulator is found in regulator_map_list. However, currently, of_regulator_dev_lookup() is used to instead of of_get_regulator(), but the variable 'r' is set to ERR_PTR(-ENODEV) instead of NULL if the regulator is not found. In this case, if no regulator is found in regulator_map_list, the variable 'r' is still ERR_PTR(-ENODEV), So regulator_dev_lookup() returns the value of 'r' directly instead of continuing to look up the regulator through regulator_lookup_by_name().

2024-09-11nvmem: layouts: add U-Boot env layoutRafał Miłecki6-165/+241
U-Boot environment variables are stored in a specific format. Actual data can be placed in various storage sources (MTD, UBI volume, EEPROM, NVRAM, etc.). Move all generic (NVMEM device independent) code from NVMEM device driver to an NVMEM layout driver. Then add a simple NVMEM layout code on top of it. This allows using NVMEM layout for parsing U-Boot env data stored in any kind of NVMEM device. The old NVMEM glue driver stays in place for handling bindings in the MTD context. To avoid code duplication it uses exported layout parsing function. Please note that handling MTD & NVMEM layout bindings may be refactored in the future.

It would be up to the users of the function to retry the call in those cases. bulk_xfer_callback_interruptible() also takes in 'mode' parameter to differentiate between VCHIQ_BULK_MODE_NOCALLBACK and VCHIQ_BULK_MODE_CALLBACK, which then is directly passed to vchiq_bulk_xfer_queue_msg_interruptible() inside the function.

Factor out core logic for preparing bulk data transfer(mutex locking, waits on vchiq_bulk_queue wait-queue, initialising the bulk transfer) out of the vchiq_bulk_transfer(). This simplifies the existing vchiq_bulk_transfer() and makes it more readable since all the core logic is handled in vchiq_bulk_xfer_queue_msg_interruptible().
