-Amlogic NAND Flash Controller (NFC) for GXBB/GXL/AXG family SoCs
-
-This file documents the properties in addition to those available in
-the MTD NAND bindings.
-
-Required properties:
-- compatible : contains one of:
- - "amlogic,meson-gxl-nfc"
- - "amlogic,meson-axg-nfc"
-- clocks :
- A list of phandle + clock-specifier pairs for the clocks listed
- in clock-names.
-
-- clock-names: Should contain the following:
- "core" - NFC module gate clock
- "device" - device clock from eMMC sub clock controller
- "rx" - rx clock phase
- "tx" - tx clock phase
-
-- amlogic,mmc-syscon : Required for NAND clocks, it's shared with SD/eMMC
- controller port C
-
-Optional children nodes:
-Children nodes represent the available nand chips.
-
-Other properties:
-see Documentation/devicetree/bindings/mtd/nand-controller.yaml for generic bindings.
-
-Example demonstrate on AXG SoC:
-
- sd_emmc_c_clkc: mmc@7000 {
- compatible = "amlogic,meson-axg-mmc-clkc", "syscon";
- reg = <0x0 0x7000 0x0 0x800>;
- };
-
- nand-controller@7800 {
- compatible = "amlogic,meson-axg-nfc";
- reg = <0x0 0x7800 0x0 0x100>;
- #address-cells = <1>;
- #size-cells = <0>;
- interrupts = <GIC_SPI 34 IRQ_TYPE_EDGE_RISING>;
-
- clocks = <&clkc CLKID_SD_EMMC_C>,
- <&sd_emmc_c_clkc CLKID_MMC_DIV>,
- <&sd_emmc_c_clkc CLKID_MMC_PHASE_RX>,
- <&sd_emmc_c_clkc CLKID_MMC_PHASE_TX>;
- clock-names = "core", "device", "rx", "tx";
- amlogic,mmc-syscon = <&sd_emmc_c_clkc>;
