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 a new regulator +for the USB hub that can be turned off when the system is suspended. + +Upstream-Status: Submitted [https://lore.kernel.org/linux-devicetree/20240301084901.16656-1-eichest@gmail.com/] +Signed-off-by: Stefan Eichenberger <stefan.eichenberger@toradex.com> +--- + .../boot/dts/ti/k3-am62-verdin-dahlia.dtsi | 22 +++++++++++++++++++ + 1 file changed, 22 insertions(+) + +diff --git a/arch/arm64/boot/dts/ti/k3-am62-verdin-dahlia.dtsi b/arch/arm64/boot/dts/ti/k3-am62-verdin-dahlia.dtsi +index bf6d27e70bc4..bb066e726527 100644 +--- a/arch/arm64/boot/dts/ti/k3-am62-verdin-dahlia.dtsi ++++ b/arch/arm64/boot/dts/ti/k3-am62-verdin-dahlia.dtsi +@@ -43,6 +43,15 @@ simple-audio-card,cpu { + sound-dai = <&mcasp0>; + }; + }; ++ ++ reg_usb_hub: regulator-usb-hub { ++ compatible = "regulator-fixed"; ++ enable-active-high; ++ /* Verdin CTRL_SLEEP_MOCI# (SODIMM 256) */ ++ gpio = <&main_gpio0 31 GPIO_ACTIVE_HIGH>; ++ regulator-boot-on; ++ regulator-name = "HUB_PWR_EN"; ++ }; + }; + + /* Verdin ETHs */ +@@ -183,6 +192,11 @@ &ospi0 { + status = "okay"; + }; + ++/* Do not force CTRL_SLEEP_MOCI# always enabled */ ++®_force_sleep_moci { ++ status = "disabled"; ++}; ++ + /* Verdin SD_1 */ + &sdhci1 { + ti,driver-strength-ohm = <33>; +@@ -204,7 +218,15 @@ &usbss1 { + }; + + &usb1 { ++ #address-cells = <1>; ++ #size-cells = <0>; + status = "okay"; ++ ++ usb-hub@1 { ++ compatible = "usb424,2744"; ++ reg = <1>; ++ vdd-supply = <®_usb_hub>; ++ }; + }; + + /* Verdin CTRL_WAKE1_MICO# */ +-- +2.40.1 + |
