Series | arm64: dts: clearfog-gt-8k: add wlan_disable signal hog | expand |
Hi Baruch, > From: Thomas Schreiber <tschreibe@gmail.com> > > There is currently no DT binding for GPIO rfkill signals. To make > mini-PCIe attached WiFi devices work, use gpio-hog to hold the > wlan_disable signal de-asserted. > > Signed-off-by: Thomas Schreiber <tschreibe@gmail.com> > [baruch: add pinctrl node; rename tag] > Signed-off-by: Baruch Siach <baruch@tkos.co.il> Applied on mvebu/dt64 Thanks, Gregory > --- > .../boot/dts/marvell/armada-8040-clearfog-gt-8k.dts | 13 ++++++++++++- > 1 file changed, 12 insertions(+), 1 deletion(-) > > diff --git a/arch/arm64/boot/dts/marvell/armada-8040-clearfog-gt-8k.dts b/arch/arm64/boot/dts/marvell/armada-8040-clearfog-gt-8k.dts > index 2468762283a5..9143aa13ceb1 100644 > --- a/arch/arm64/boot/dts/marvell/armada-8040-clearfog-gt-8k.dts > +++ b/arch/arm64/boot/dts/marvell/armada-8040-clearfog-gt-8k.dts > @@ -226,6 +226,11 @@ > marvell,function = "gpio"; > }; > > + cp0_wlan_disable_pins: wlan-disable-pins { > + marvell,pins = "mpp51"; > + marvell,function = "gpio"; > + }; > + > cp0_sdhci_pins: sdhci-pins { > marvell,pins = "mpp55", "mpp56", "mpp57", "mpp58", "mpp59", > "mpp60", "mpp61"; > @@ -235,7 +240,7 @@ > > &cp0_pcie0 { > pinctrl-names = "default"; > - pinctrl-0 = <&cp0_pci0_reset_pins>; > + pinctrl-0 = <&cp0_pci0_reset_pins &cp0_wlan_disable_pins>; > reset-gpios = <&cp0_gpio2 0 GPIO_ACTIVE_LOW>; > status = "okay"; > }; > @@ -253,6 +258,12 @@ > output-low; > }; > > + wlan_disable { > + gpio-hog; > + gpios = <19 GPIO_ACTIVE_LOW>; > + output-low; > + }; > + > lte_disable { > gpio-hog; > gpios = <21 GPIO_ACTIVE_LOW>; > -- > 2.20.1 >
