2022-09-19dt-bindings: mtd: partitions: add binding for U-Boot bootloaderRafał Miłecki1-0/+49
Right now there is no (known) real reason for a custom binding for standard U-Boot partitions. Broadcom's U-Boot however requires extra handling - looking for environment variables subblocks. This commit adds Broadcom specific binding.

Pull MTD updates from Richard Weinberger: "MTD core changes: - Dynamic partition support - Fix deadlock in sm_ftl - Various refcount fixes in maps, partitions and parser code - Integer overflow fixes in mtdchar - Support for Sercomm partitions NAND driver changes: - Clockrate fix for arasan - Add ATO25D1GA support - Double free fix for meson driver - Fix probe/remove methods in cafe NAND - Support unprotected spare data pages in qcom_nandc SPI NOR core changes: - move SECT_4K_PMC flag out of the core as it's a vendor specific flag - s/addr_width/addr_nbytes/g: address width means the number of IO lines used for the address, whereas in the code it is used as the number of address bytes. - do not change nor->addr_nbytes at SFDP parsing time. At the SFDP parsing time we should not change members of struct spi_nor, but instead fill members of struct spi_nor_flash_parameters which could later on be used by the callers. - track flash's internal address mode so that we can use 4B opcodes together with opcodes that don't have a 4B opcode correspondent. SPI NOR manufacturer drivers changes: - esmt: Rename "f25l32qa" flash name to "f25l32qa-2s". - micron-st: Skip FSR reading if SPI controller does not support it to allow flashes that support FSR to work even when attached to such SPI controllers. - spansion: Add s25hl-t/s25hs-t IDs and fixups" * tag 'mtd/for-5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux: (53 commits) mtd: core: check partition before dereference mtd: spi-nor: fix spi_nor_spimem_setup_op() call in spi_nor_erase_{sector,chip}() mtd: spi-nor: spansion: Add s25hl-t/s25hs-t IDs and fixups mtd: spi-nor: spansion: Add local function to discover page size mtd: spi-nor: core: Track flash's internal address mode mtd: spi-nor: core: Return error code from set_4byte_addr_mode() mtd: spi-nor: Do not change nor->addr_nbytes at SFDP parsing time mtd: spi-nor: core: Shrink the storage size of the flash_info's addr_nbytes mtd: spi-nor: s/addr_width/addr_nbytes mtd: spi-nor: esmt: Use correct name of f25l32qa mtd: spi-nor: micron-st: Skip FSR reading if SPI controller does not support it MAINTAINERS: Use my kernel.org email mtd: rawnand: arasan: Fix clock rate in NV-DDR mtd: rawnand: arasan: Update NAND bus clock instead of system clock mtd: core: introduce of support for dynamic partitions dt-bindings: mtd: partitions: add additional example for qcom,smem-part dt-bindings: mtd: partitions: support label/name only partition mtd: spi-nor: move SECT_4K_PMC special handling mtd: dataflash: Add SPI ID table mtd: hyperbus: rpc-if: Fix RPM imbalance in probe error path ...

2022-06-29dt-bindings: mtd: partitions: support label/name only partitionChristian Marangi1-2/+18
Document new partition nodes that declare only the label/name instead of the reg used to provide an OF node for partition registred at runtime by parsers. This is required for nvmem system to declare and detect nvmem-cells. With these special partitions, the reg / offset is not required and a 'partition-' prefix is needed. The node name with the 'partition-' prefix stripped, is used to match the partition allocated by the parser at runtime and the parser will provide reg and offset of the mtd. If the partition to match contains invalid char for a node name, the label binding can be used to declare the partition name. NVMEM will use the data from the parser and provide the NVMEM cells declared in the DTS, "connecting" the dynamic partition with a static declaration of cells in them.
