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.
|
||
|
|
|
||
|
|
