Merge tag 'char-misc-6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char/misc and other driver subsystem updates from Greg KH: "Here is the large set of driver changes for char/misc drivers and other smaller driver subsystems that flow through this git tree. Included in here are: - New IIO drivers and features and improvments in that subsystem - New hwtracing drivers and additions to that subsystem - lots of interconnect changes and new drivers as that subsystem seems under very active development recently. This required also merging in the icc subsystem changes through this tree. - FPGA driver updates - counter subsystem and driver updates - MHI driver updates - nvmem driver updates - documentation updates - Other smaller driver updates and fixes, full details in the shortlog All of these have been in linux-next for a while with no reported problems" * tag 'char-misc-6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (223 commits) scripts/tags.sh: fix incompatibility with PCRE2 firmware: coreboot: Remove GOOGLE_COREBOOT_TABLE_ACPI/OF Kconfig entries mei: lower the log level for non-fatal failed messages mei: bus: disallow driver match while dismantling device misc: vmw_balloon: fix memory leak with using debugfs_lookup() nvmem: stm32: fix OPTEE dependency dt-bindings: nvmem: qfprom: add IPQ8074 compatible nvmem: qcom-spmi-sdam: register at device init time nvmem: rave-sp-eeprm: fix kernel-doc bad line warning nvmem: stm32: detect bsec pta presence for STM32MP15x nvmem: stm32: add OP-TEE support for STM32MP13x nvmem: core: use nvmem_add_one_cell() in nvmem_add_cells_from_of() nvmem: core: add nvmem_add_one_cell() nvmem: core: drop the removal of the cells in nvmem_add_cells() nvmem: core: move struct nvmem_cell_info to nvmem-provider.h nvmem: core: add an index parameter to the cell of: property: add #nvmem-cell-cells property of: property: make #.*-cells optional for simple props of: base: add of_parse_phandle_with_optional_args() net: add helper eth_addr_add() ...
