However, the +Dahlia carrier board supports disabling the sleep-moci when the system +is suspended to power down peripherals that support it. This reduces +overall power consumption. This commit adds support for this feature by +disabling the reg_force_sleep_moci regulator and adding two new +regulators for the USB hub and PCIe that can be turned off when the +system is suspended. + +Upstream-Status: Submitted [https://lore.kernel.org/linux-devicetree/20240405160720.5977-1-eichest@gmail.com/] +Signed-off-by: Stefan Eichenberger <stefan.eichenberger@toradex.com> +--- + .../dts/freescale/imx8mp-verdin-dahlia.dtsi | 44 +++++++++++++++++++ + 1 file changed, 44 insertions(+) + +diff --git a/arch/arm64/boot/dts/freescale/imx8mp-verdin-dahlia.dtsi b/arch/arm64/boot/dts/freescale/imx8mp-verdin-dahlia.dtsi +index e68e0e6f21e9..abad1887040a 100644 +--- a/arch/arm64/boot/dts/freescale/imx8mp-verdin-dahlia.dtsi ++++ b/arch/arm64/boot/dts/freescale/imx8mp-verdin-dahlia.dtsi +@@ -32,6 +32,25 @@ simple-audio-card,cpu { + sound-dai = <&sai1>; + }; + }; ++ ++ reg_usb_hub: regulator-usb-hub { ++ compatible = "regulator-fixed"; ++ enable-active-high; ++ /* Verdin CTRL_SLEEP_MOCI# (SODIMM 256) */ ++ gpio = <&gpio4 29 GPIO_ACTIVE_HIGH>; ++ regulator-boot-on; ++ regulator-name = "HUB_PWR_EN"; ++ }; ++ ++ reg_pcie: regulator-pcie { ++ compatible = "regulator-fixed"; ++ enable-active-high; ++ /* Verdin CTRL_SLEEP_MOCI# (SODIMM 256) */ ++ gpio = <&gpio4 29 GPIO_ACTIVE_HIGH>; ++ regulator-boot-on; ++ regulator-name = "PCIE_1_PWR_EN"; ++ startup-delay-us = <100000>; ++ }; + }; + + &backlight { +@@ -117,6 +136,7 @@ wm8904_1a: audio-codec@1a { + + /* Verdin PCIE_1 */ + &pcie { ++ vpcie-supply = <®_pcie>; + status = "okay"; + }; + +@@ -143,6 +163,11 @@ ®_usdhc2_vmmc { + vin-supply = <®_3p3v>; + }; + ++/* We support turning off sleep moci on Dahlia */ ++®_force_sleep_moci { ++ status = "disabled"; ++}; ++ + /* Verdin I2S_1 */ + &sai1 { + assigned-clocks = <&clk IMX8MP_CLK_SAI1>; +@@ -186,6 +211,25 @@ &usb3_phy1 { + status = "okay"; + }; + ++&usb_dwc3_1 { ++ #address-cells = <1>; ++ #size-cells = <0>; ++ ++ usb_hub_3_0: usb-hub@1 { ++ compatible = "usb424,5744"; ++ reg = <1>; ++ peer-hub = <&usb_hub_2_0>; ++ vdd-supply = <®_usb_hub>; ++ }; ++ ++ usb_hub_2_0: usb-hub@2 { ++ compatible = "usb424,2744"; ++ reg = <2>; ++ peer-hub = <&usb_hub_3_0>; ++ vdd-supply = <®_usb_hub>; ++ }; ++}; ++ + /* Verdin SD_1 */ + &usdhc2 { + status = "okay"; +-- +2.40.1 + |
