* Cadence Universal Flash Storage (UFS) Controller
|
||||
|
||||
UFS nodes are defined to describe on-chip UFS host controllers.
|
||||
Each UFS controller instance should have its own node.
|
||||
Please see the ufshcd-pltfrm.txt for a list of all available properties.
|
||||
|
||||
Required properties:
|
||||
- compatible : Compatible list, contains one of the following controllers:
|
||||
"cdns,ufshc" - Generic CDNS HCI,
|
||||
"cdns,ufshc-m31-16nm" - CDNS UFS HC + M31 16nm PHY
|
||||
complemented with the JEDEC version:
|
||||
"jedec,ufs-2.0"
|
||||
|
||||
- reg : Address and length of the UFS register set.
|
||||
- interrupts : One interrupt mapping.
|
||||
- freq-table-hz : Clock frequency table.
|
||||
See the ufshcd-pltfrm.txt for details.
|
||||
- clocks : List of phandle and clock specifier pairs.
|
||||
- clock-names : List of clock input name strings sorted in the same
|
||||
order as the clocks property. "core_clk" is mandatory.
|
||||
Depending on a type of a PHY,
|
||||
the "phy_clk" clock can also be added, if needed.
|
||||
|
||||
Example:
|
||||
ufs@fd030000 {
|
||||
compatible = "cdns,ufshc", "jedec,ufs-2.0";
|
||||
reg = <0xfd030000 0x10000>;
|
||||
interrupts = <0 1 IRQ_TYPE_LEVEL_HIGH>;
|
||||
freq-table-hz = <0 0>, <0 0>;
|
||||
clocks = <&ufs_core_clk>, <&ufs_phy_clk>;
|
||||
clock-names = "core_clk", "phy_clk";
|
||||
};
