dt-bindings: mtd: Add realtek,rtl9301-ecc

2025-09-29T15:54:33+00:00

Add a dtschema for the ECC engine on the Realtek RTL93xx SoCs. The engine supports BCH6 and BCH12 parity for 512 byte blocks. The hardware can make use of interrupts but this is not yet supported by the driver. From the known datasheets it is connected to the LXB (lexra bus) and propably depends on its clock. Provide an optional clock property that can describe the relation. Signed-off-by: Markus Stockhausen Reviewed-by: Rob Herring (Arm) Signed-off-by: Miquel Raynal

Samsung S3C24xx family of SoCs was removed from the Linux kernel in the commit 61b7f8920b17 ("ARM: s3c: remove all s3c24xx support"), in January 2023. There are no in-kernel users of its compatibles. Signed-off-by: Krzysztof Kozlowski Acked-by: Rob Herring (Arm) Signed-off-by: Miquel Raynal

Pull mtd updates from Miquel Raynal: "MTD changes: - Apart from a binding conversion to yaml, only minor changes/small fixes have been merged. Raw NAND changes: - Minor fixes for various controller drivers like DMA mapping checks, better timing derivations or bitflip statistics. - some Hynix NAND flashes were not supporting read-retries, so don't even try to do it SPI NAND changes: - In order to support high-speed modes, certain chips need extra configuration like adding more dummy cycles. This is now possible, especially on Winbond chips. - Aside from that, Gigadevice gets support for a new chip (GD5F1GM9). SPI NOR changes: - A notable changes is the fix for exiting 4-byte addressing on Infineon SEMPER flashes. These flashes do not support the standard EX4B opcode (E9h), and use a vendor-specific opcode (B8h) instead. - There is also a fix for unlocking flashes that are write-protected at power-on.

dt-bindings: Correct indentation and style in DTS example

2025-07-29T00:56:29+00:00

DTS example in the bindings should be indented with 2- or 4-spaces and aligned with opening '- |', so correct any differences like 3-spaces or mixtures 2- and 4-spaces in one binding. No functional changes here, but saves some comments during reviews of new patches built on existing code.

2025-06-02T16:39:50+00:00

The SPI NAND subsystem has seen the introduction of DTR operations (the equivalent of DDR transfers), which involved quite a few preparation patches for clarifying macro names. In the raw NAND subsystem, the brcmnand driver has been "fixed" for old legacy SoCs with an update of the ->exec_op() hook, there has been the introduction of a new controller driver named Loongson-1, and the Qualcomm driver has received quite a few misc fixes as well as a new compatible. Aside from this, there is the usual load of misc improvement and fixes.
