MediaTek Universal Flash Storage (UFS) M-PHY binding
|
|
--------------------------------------------------------
|
|
|
|
UFS M-PHY nodes are defined to describe on-chip UFS M-PHY hardware macro.
|
|
Each UFS M-PHY node should have its own node.
|
|
|
|
To bind UFS M-PHY with UFS host controller, the controller node should
|
|
contain a phandle reference to UFS M-PHY node.
|
|
|
|
Required properties for UFS M-PHY nodes:
|
|
- compatible : Compatible list, contains the following controller:
|
|
"mediatek,mt8183-ufsphy" for ufs phy
|
|
persent on MT81xx chipsets.
|
|
- reg : Address and length of the UFS M-PHY register set.
|
|
- #phy-cells : This property shall be set to 0.
|
|
- 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. Following clocks are
|
|
mandatory.
|
|
"unipro": Unipro core control clock.
|
|
"mp": M-PHY core control clock.
|
|
|
|
Example:
|
|
|
|
ufsphy: phy@11fa0000 {
|
|
compatible = "mediatek,mt8183-ufsphy";
|
|
reg = <0 0x11fa0000 0 0xc000>;
|
|
#phy-cells = <0>;
|
|
|
|
clocks = <&infracfg_ao INFRACFG_AO_UNIPRO_SCK_CG>,
|
|
<&infracfg_ao INFRACFG_AO_UFS_MP_SAP_BCLK_CG>;
|
|
clock-names = "unipro", "mp";
|
|
};
|
|
|
|
ufshci@11270000 {
|
|
...
|
|
phys = <&ufsphy>;
|
|
};
