From: Lucas Stach <l.stach@xxxxxxxxxxxxxx> This adds the PGC and HDMI blk-ctrl nodes providing power control for HDMI subsystem peripherals. Signed-off-by: Lucas Stach <l.stach@xxxxxxxxxxxxxx> Signed-off-by: Adam Ford <aford173@xxxxxxxxx> --- V2: Added the fdcc to hdmi_blk_ctrl per NXP's downstream kernel guidance I (Adam) tried to help move this along, so I took Lucas' patch and attempted to apply fixes based on feedback. I don't have all the history, so apologies for that. diff --git a/arch/arm64/boot/dts/freescale/imx8mp.dtsi b/arch/arm64/boot/dts/freescale/imx8mp.dtsi index 76c73daf546b..d695c80e710c 100644 --- a/arch/arm64/boot/dts/freescale/imx8mp.dtsi +++ b/arch/arm64/boot/dts/freescale/imx8mp.dtsi @@ -836,6 +836,23 @@ pgc_mediamix: power-domain@10 { <&clk IMX8MP_CLK_MEDIA_APB_ROOT>; }; + pgc_hdmimix: power-domains@14 { + #power-domain-cells = <0>; + reg = <IMX8MP_POWER_DOMAIN_HDMIMIX>; + clocks = <&clk IMX8MP_CLK_HDMI_ROOT>, + <&clk IMX8MP_CLK_HDMI_APB>; + assigned-clocks = <&clk IMX8MP_CLK_HDMI_AXI>, + <&clk IMX8MP_CLK_HDMI_APB>; + assigned-clock-parents = <&clk IMX8MP_SYS_PLL2_500M>, + <&clk IMX8MP_SYS_PLL1_133M>; + assigned-clock-rates = <500000000>, <133000000>; + }; + + pgc_hdmi_phy: power-domains@15 { + #power-domain-cells = <0>; + reg = <IMX8MP_POWER_DOMAIN_HDMI_PHY>; + }; + pgc_mipi_phy2: power-domain@16 { #power-domain-cells = <0>; reg = <IMX8MP_POWER_DOMAIN_MIPI_PHY2>; @@ -1361,6 +1378,25 @@ eqos: ethernet@30bf0000 { intf_mode = <&gpr 0x4>; status = "disabled"; }; + + hdmi_blk_ctrl: blk-ctrl@32fc0000 { + compatible = "fsl,imx8mp-hdmi-blk-ctrl", "syscon"; + reg = <0x32fc0000 0x23c>; + clocks = <&clk IMX8MP_CLK_HDMI_APB>, + <&clk IMX8MP_CLK_HDMI_ROOT>, + <&clk IMX8MP_CLK_HDMI_REF_266M>, + <&clk IMX8MP_CLK_HDMI_24M>, + <&clk IMX8MP_CLK_HDMI_FDCC_TST>; + clock-names = "apb", "axi", "ref_266m", "ref_24m", "fdcc"; + power-domains = <&pgc_hdmimix>, <&pgc_hdmimix>, + <&pgc_hdmimix>, <&pgc_hdmimix>, + <&pgc_hdmimix>, <&pgc_hdmimix>, + <&pgc_hdmimix>, <&pgc_hdmi_phy>; + power-domain-names = "bus", "irqsteer", "lcdif", + "pai", "pvi", "trng", + "hdmi-tx", "hdmi-tx-phy"; + #power-domain-cells = <1>; + }; }; aips5: bus@30c00000 { -- 2.43.0
