-* Mediatek Universal Flash Storage (UFS) Host Controller
-
-UFS nodes are defined to describe on-chip UFS hardware macro.
-Each UFS Host Controller should have its own node.
-
-To bind UFS PHY with UFS host controller, the controller node should
-contain a phandle reference to UFS M-PHY node.
-
-Required properties for UFS nodes:
-- compatible : Compatible list, contains the following controller:
- "mediatek,mt8183-ufshci" for MediaTek UFS host controller
- present on MT8183 chipsets.
- "mediatek,mt8192-ufshci" for MediaTek UFS host controller
- present on MT8192 chipsets.
-- reg : Address and length of the UFS register set.
-- phys : phandle to m-phy.
-- 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. "ufs" is mandatory.
- "ufs": ufshci core control clock.
-- freq-table-hz : Array of <min max> operating frequencies stored in the same
- order as the clocks property. If this property is not
- defined or a value in the array is "0" then it is assumed
- that the frequency is set by the parent clock or a
- fixed rate clock source.
-- vcc-supply : phandle to VCC supply regulator node.
-
-Example:
-
- ufsphy: phy@11fa0000 {
- ...
- };
-
- ufshci@11270000 {
- compatible = "mediatek,mt8183-ufshci";
- reg = <0 0x11270000 0 0x2300>;
- interrupts = <GIC_SPI 104 IRQ_TYPE_LEVEL_LOW>;
- phys = <&ufsphy>;
-
- clocks = <&infracfg_ao INFRACFG_AO_UFS_CG>;
- clock-names = "ufs";
- freq-table-hz = <0 0>;
-
- vcc-supply = <&mt_pmic_vemc_ldo_reg>;
- };
