Merge tag 'mtd/for-5.4' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux
Pull MTD updates from Richard Weinberger: "MTD core changes: - add debugfs nodes for querying the flash name and id - mtd parser reorganization SPI NOR core changes: - always use bounce buffer for register read/writes - move m25p80 code in spi-nor.c - rework hwcaps selection for the spi-mem case - rework the core in order to move the manufacturer specific code out of it: - regroup flash parameters in 'struct spi_nor_flash_parameter' - add default_init() and post_sfdp() hooks to tweak the flash parameters - introduce the ->set_4byte(), ->convert_addr() and ->setup() methods, to deal with manufacturer specific code - rework the SPI NOR lock/unlock logic - fix an error code in spi_nor_read_raw() - fix a memory leak bug - enable the debugfs for the partname and partid - add support for few flashes SPI NOR controller drivers changes: - intel-spi: - Whitelist 4B read commands - Add support for Intel Tiger Lake SPI serial flash - aspeed-smc: Add of_node_put() - hisi-sfc: add of_node_put() - cadence-quadspi: Fix QSPI RCU Schedule Stall NAND core: - Fixing typos - Adding missing of_node_put() in various drivers Raw NAND controller drivers: - Macronix: new controller driver - Omap2: fix the number of bitflips returned - Brcmnand: fix a pointer not iterating over all the page chunks - W90x900: driver removed - Onenand: fix a memory leak - Sharpsl: missing include guard - STM32: avoid warnings when building with W=1 - Ingenic: fix a coccinelle warning - r852: call a helper to simplify the code CFI core: - Kill useless initializer in mtd_do_chip_probe() - Fix a rare write failure seen on some cfi_cmdset_0002 compliant Parallel NORs - Bunch of cleanups for cfi_cmdset_0002 driver's write functions by Tokunori Ikegami" * tag 'mtd/for-5.4' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux: (77 commits) mtd: pmc551: Remove set but not used variable 'soff_lo' mtd: cfi_cmdset_0002: Fix do_erase_chip() to get chip as erasing mode mtd: sm_ftl: Fix memory leak in sm_init_zone() error path mtd: parsers: Move CMDLINE parser mtd: parsers: Move OF parser mtd: parsers: Move BCM63xx parser mtd: parsers: Move BCM47xx parser mtd: parsers: Move TI AR7 parser mtd: pismo: Simplify getting the adapter of a client mtd: phram: Module parameters add writable permissions mtd: pxa2xx: Use ioremap_cache insted of ioremap_cached mtd: spi-nor: Rename "n25q512a" to "mt25qu512a (n25q512a)" mtd: spi-nor: Add support for mt35xu02g mtd: rawnand: omap2: Fix number of bitflips reporting with ELM mtd: rawnand: brcmnand: Fix ecc chunk calculation for erased page bitfips mtd: spi-nor: remove superfluous pass of nor->info->sector_size mtd: spi-nor: enable the debugfs for the partname and partid mtd: mtdcore: add debugfs nodes for querying the flash name and id mtd: spi-nor: hisi-sfc: Add of_node_put() before break mtd: spi-nor: aspeed-smc: Add of_node_put() ...

+Macronix Raw NAND Controller Device Tree Bindings
+-------------------------------------------------
+
+Required properties:
+- compatible: should be "mxic,multi-itfc-v009-nand-controller"
+- reg: should contain 1 entry for the registers
+- #address-cells: should be set to 1
+- #size-cells: should be set to 0
+- interrupts: interrupt line connected to this raw NAND controller
+- clock-names: should contain "ps", "send" and "send_dly"
+- clocks: should contain 3 phandles for the "ps", "send" and
+ "send_dly" clocks
+
+Children nodes:
+- children nodes represent the available NAND chips.
+
+See Documentation/devicetree/bindings/mtd/nand-controller.yaml
+for more details on generic bindings.
+
+Example:
+
+ nand: nand-controller@43c30000 {
+ compatible = "mxic,multi-itfc-v009-nand-controller";
+ reg = <0x43c30000 0x10000>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+ interrupts = <GIC_SPI 0x1d IRQ_TYPE_EDGE_RISING>;
+ clocks = <&clkwizard 0>, <&clkwizard 1>, <&clkc 15>;
+ clock-names = "send", "send_dly", "ps";
+
+ nand@0 {
+ reg = <0>;
+ nand-ecc-mode = "soft";
+ nand-ecc-algo = "bch";
+ };
+ };
