Merge tag 'nand/for-5.19' into mtd/next
NAND core: * Print offset instead of page number for bad blocks Raw NAND controller drivers: * Cadence: Fix possible null-ptr-deref in cadence_nand_dt_probe() * CS553X: simplify the return expression of cs553x_write_ctrl_byte() * Davinci: Remove redundant unsigned comparison to zero * Denali: Use managed device resources * GPMI: - Add large oob bch setting support - Rename the variable ecc_chunk_size - Uninline the gpmi_check_ecc function - Add strict ecc strength check - Refactor BCH geometry settings function * Intel: Fix possible null-ptr-deref in ebu_nand_probe() * MPC5121: Check before clk_disable_unprepare() not needed * Mtk: - MTD_NAND_ECC_MEDIATEK should depend on ARCH_MEDIATEK - Also parse the default nand-ecc-engine property if available - Make mtk_ecc.c a separated module * OMAP ELM: - Convert the bindings to yaml - Describe the bindings for AM64 ELM - Add support for its compatible * Renesas: Use runtime PM instead of the raw clock API and update the bindings accordingly * Rockchip: Check before clk_disable_unprepare() not needed * TMIO: Check return value after calling platform_get_resource() Raw NAND chip driver: * Kioxia: Add support for TH58NVG3S0HBAI4 and TC58NVG0S3HTA00 SPI-NAND chip drivers: * Gigadevice: - Add support for: - GD5FxGM7xExxG - GD5F{2,4}GQ5xExxG - GD5F1GQ5RExxG - GD5FxGQ4xExxG - Fix Quad IO for GD5F1GQ5UExxG * XTX: Add support for XT26G0xA Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com>
