2022-09-30counter: interrupt-cnt: Implement watch_validate callbackWilliam Breathitt Gray1-0/+11
The interrupt-cnt counter driver only pushes one type of event on only one channel: COUNTER_EVENT_CHANGE_OF_STATE on channel 0. The interrupt_cnt_watch_validate() watch_valid callback is implemented to ensure watch configurations are valid for this driver.

2022-09-28fsi: core: Check error number after calling ida_simple_getJiasheng Jiang1-0/+3
If allocation fails, the ida_simple_get() will return error number. So master->idx could be error number and be used in dev_set_name(). Therefore, it should be better to check it and return error if fails, like the ida_simple_get() in __fsi_get_new_minor().

2022-09-24firmware: google: Test spinlock on panic path to avoid lockupsGuilherme G. Piccoli1-0/+9
Currently the gsmi driver registers a panic notifier as well as reboot and die notifiers. The callbacks registered are called in atomic and very limited context - for instance, panic disables preemption and local IRQs, also all secondary CPUs (not executing the panic path) are shutdown. With that said, taking a spinlock in this scenario is a dangerous invitation for lockup scenarios. So, fix that by checking if the spinlock is free to acquire in the panic notifier callback - if not, bail-out and avoid a potential hang.

2022-09-24nvmem: brcm_nvram: Use kzalloc for allocating only one elementKenneth Lee1-1/+1
Use kzalloc(...) rather than kcalloc(1, ...) because the number of elements we are specifying in this case is 1, so kzalloc would accomplish the same thing and we can simplify.

2022-09-24mtd: allow getting MTD device associated with a specific DT nodeRafał Miłecki2-0/+29
MTD subsystem API allows interacting with MTD devices (e.g. reading, writing, handling bad blocks). So far a random driver could get MTD device only by its name (get_mtd_device_nm()). This change allows getting them also by a DT node. This API is required for drivers handling DT defined MTD partitions in a specific way (e.g. U-Boot (sub)partition with environment variables).

2022-09-24nvmem: add driver handling U-Boot environment variablesRafał Miłecki4-0/+234
U-Boot stores its setup as environment variables. It's a list of key-value pairs stored on flash device with a custom header. This commit adds an NVMEM driver that: 1. Provides NVMEM access to environment vars binary data 2. Extracts variables as NVMEM cells Current Linux's NVMEM sysfs API allows reading whole NVMEM data block. It can be used by user-space tools for reading U-Boot env vars block without the hassle of finding its location. Parsing will still need to be re-done there. Kernel-parsed NVMEM cells can be read however by Linux drivers. This may be useful for Ethernet drivers for reading device MAC address which is often stored as U-Boot env variable.
