2022-05-16	mtd: rawnand: rockchip: Check before clk_disable_unprepare() not needed	Phil Edworthy	1	-4/+2
	All code in clk_disable_unprepare() already checks the clk ptr using IS_ERR_OR_NULL so there is no need to check it again before calling it. A lot of other drivers already rely on this behaviour, so it's safe to do so here.

2022-03-14	mtd: rawnand: rockchip: fix platform_get_irq.cocci warning	Yihao Han	1	-1/+0
	Remove dev_err() messages after platform_get_irq*() failures. platform_get_irq() already prints an error.

	Suppresses the following coccinelle warning: drivers/mtd/nand/raw/rockchip-nand-controller.c:162:4-8: WARNING use flexible-array member instead Signed-off-by: Zou Wei <zou_wei@huawei.com> Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com> Link: https://lore.kernel.org/linux-mtd/20210323131137.45552-1-zou_wei@huawei.com
2020-12-10	mtd: rawnand: rockchip: NFC driver for RK3308, RK2928 and others	Yifeng Zhao	1	-0/+1495
	This driver supports Rockchip NFC (NAND Flash Controller) found on RK3308, RK2928, RKPX30, RV1108 and other SOCs. The driver has been tested using 8-bit NAND interface on the ARM based RK3308 platform. Support Rockchip SoCs and NFC versions: - PX30 and RK3326(NFCv900). ECC: 16/40/60/70 bits/1KB. CLOCK: ahb and nfc. - RK3308 and RV1108(NFCv800). ECC: 16 bits/1KB. CLOCK: ahb and nfc. - RK3036 and RK3128(NFCv622). ECC: 16/24/40/60 bits/1KB. CLOCK: ahb and nfc. - RK3066, RK3188 and RK2928(NFCv600). ECC: 16/24/40/60 bits/1KB. CLOCK: ahb. Supported features: - Read full page data by DMA. - Support HW ECC(one step is 1KB). - Support 2 - 32K page size. - Support 8 CS(depend on SoCs) Limitations: - No support for the ecc step size is 512. - Untested on some SoCs. - No support for subpages. - No support for the builtin randomizer. - The original bad block mask is not supported. It is recommended to use the BBT(bad block table).
