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/imx8mm-verdin-dahlia.dtsi | 33 +++++++++++++++++++ + 1 file changed, 33 insertions(+) + +diff --git a/arch/arm64/boot/dts/freescale/imx8mm-verdin-dahlia.dtsi b/arch/arm64/boot/dts/freescale/imx8mm-verdin-dahlia.dtsi +index b64dac4f29c2..393fc9e20423 100644 +--- a/arch/arm64/boot/dts/freescale/imx8mm-verdin-dahlia.dtsi ++++ b/arch/arm64/boot/dts/freescale/imx8mm-verdin-dahlia.dtsi +@@ -32,6 +32,25 @@ simple-audio-card,cpu { + sound-dai = <&sai2>; + }; + }; ++ ++ reg_usb_hub: regulator-usb-hub { ++ compatible = "regulator-fixed"; ++ enable-active-high; ++ /* Verdin CTRL_SLEEP_MOCI# (SODIMM 256) */ ++ gpio = <&gpio5 1 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 = <&gpio5 1 GPIO_ACTIVE_HIGH>; ++ regulator-boot-on; ++ regulator-name = "PCIE_1_PWR_EN"; ++ startup-delay-us = <100000>; ++ }; + }; + + /* Verdin SPI_1 */ +@@ -98,6 +117,7 @@ wm8904_1a: audio-codec@1a { + + /* Verdin PCIE_1 */ + &pcie0 { ++ vpcie-supply = <®_pcie>; + status = "okay"; + }; + +@@ -120,6 +140,11 @@ &pwm3 { + status = "okay"; + }; + ++/* We support turning off sleep moci on Dahlia */ ++®_force_sleep_moci { ++ status = "disabled"; ++}; ++ + /* Verdin I2S_1 */ + &sai2 { + status = "okay"; +@@ -148,8 +173,16 @@ &usbotg1 { + + /* Verdin USB_2 */ + &usbotg2 { ++ #address-cells = <1>; ++ #size-cells = <0>; + disable-over-current; + status = "okay"; ++ ++ usb-hub@1 { ++ compatible = "usb424,2744"; ++ reg = <1>; ++ vdd-supply = <®_usb_hub>; ++ }; + }; + + /* Verdin SD_1 */ +-- +2.40.1 + |
