IMX7D_IPG_ROOT_CLK is currently not a valid clock in upstream... So we would have to add it to the clock driver first. I guess we could/should add it anyway at one point? But probably also as init on, just to make sure Linux does not disable it since it is currently used by several IPs implicitly. -- Stefan > > Otherwise, > > Acked-by: Dong Aisheng <aisheng.dong@nxp.com> > > Regards > Dong Aisheng > >> - <&clks IMX7D_CLK_DUMMY>, >> + <&clks IMX7D_NAND_USDHC_BUS_ROOT_CLK>, >> <&clks IMX7D_USDHC1_ROOT_CLK>; >> clock-names = "ipg", "ahb", "per"; >> bus-width = <4>; >> @@ -948,7 +948,7 @@ >> reg = <0x30b50000 0x10000>; >> interrupts = <GIC_SPI 23 IRQ_TYPE_LEVEL_HIGH>; >> clocks = <&clks IMX7D_CLK_DUMMY>, >> - <&clks IMX7D_CLK_DUMMY>, >> + <&clks IMX7D_NAND_USDHC_BUS_ROOT_CLK>, >> <&clks IMX7D_USDHC2_ROOT_CLK>; >> clock-names = "ipg", "ahb", "per"; >> bus-width = <4>; >> @@ -960,7 +960,7 @@ >> reg = <0x30b60000 0x10000>; >> interrupts = <GIC_SPI 24 IRQ_TYPE_LEVEL_HIGH>; >> clocks = <&clks IMX7D_CLK_DUMMY>, >> - <&clks IMX7D_CLK_DUMMY>, >> + <&clks IMX7D_NAND_USDHC_BUS_ROOT_CLK>, >> <&clks IMX7D_USDHC3_ROOT_CLK>; >> clock-names = "ipg", "ahb", "per"; >> bus-width = <4>; >> -- >> 2.12.1 >>
