Previously a common MMC sub clock framework is implemented and shared by EMMC and NAND, but that is coupling the EMMC and NAND, although EMMC and NAND is mutually exclusive. see the link: [https://lore.kernel.org/all/1jy23226sa.fsf@starbuckisacylon.baylibre.com/] Now we plan to abandon common mmc sub clock framework and recovery the series. Changes since v1 [2] - use clk_parent_data instead of parent_names - define a reg resource instead of sd_emmc_c_clkc [1] https://lore.kernel.org/r/20220106033130.37623-1-liang.yang@amlogic.com https://lore.kernel.org/r/20220106032504.23310-1-liang.yang@amlogic.com Liang Yang (2): mtd: rawnand: meson: discard the common MMC sub clock framework dt-bindings: nand: meson: refine Amlogic NAND controller driver .../bindings/mtd/amlogic,meson-nand.txt | 60 ------- .../bindings/mtd/amlogic,meson-nand.yaml | 70 ++++++++ drivers/mtd/nand/raw/meson_nand.c | 161 ++++++++++-------- 3 files changed, 159 insertions(+), 132 deletions(-) delete mode 100644 Documentation/devicetree/bindings/mtd/amlogic,meson-nand.txt create mode 100644 Documentation/devicetree/bindings/mtd/amlogic,meson-nand.yaml -- 2.34.1 ______________________________________________________ Linux MTD discussion mailing list http://lists.infradead.org/mailman/listinfo/linux-mtd/
