From 4c8777892e80bbe39efd0584502793b4b244f99b Mon Sep 17 00:00:00 2001 From: Steve Longerbeam Date: Mon, 12 Jun 2017 11:23:58 -0700 Subject: [PATCH] ARM: dts: imx6qdl-sabrelite: remove erratum ERR006687 workaround There is a pin conflict with GPIO_6. This pin functions as a power input pin to the OV5642 camera sensor, but ENET uses it as the h/w workaround for erratum ERR006687, to wake-up the ARM cores on normal RX and TX packet done events. So we need to remove the h/w workaround to support the OV5642. The result is that the CPUidle driver will no longer allow entering the deep idle states on the sabrelite. This is a partial revert of commit 6261c4c8f13e ("ARM: dts: imx6qdl-sabrelite: use GPIO_6 for FEC interrupt.") commit a28eeb43ee57 ("ARM: dts: imx6: tag boards that have the HW workaround for ERR006687") Signed-off-by: Steve Longerbeam Reviewed-by: Fabio Estevam Signed-off-by: Shawn Guo --- arch/arm/boot/dts/imx6qdl-sabrelite.dtsi | 4 ---- 1 file changed, 4 deletions(-) diff --git a/arch/arm/boot/dts/imx6qdl-sabrelite.dtsi b/arch/arm/boot/dts/imx6qdl-sabrelite.dtsi index 84131794e97b..89dce27dfbad 100644 --- a/arch/arm/boot/dts/imx6qdl-sabrelite.dtsi +++ b/arch/arm/boot/dts/imx6qdl-sabrelite.dtsi @@ -270,9 +270,6 @@ txd1-skew-ps = <0>; txd2-skew-ps = <0>; txd3-skew-ps = <0>; - interrupts-extended = <&gpio1 6 IRQ_TYPE_LEVEL_HIGH>, - <&intc 0 119 IRQ_TYPE_LEVEL_HIGH>; - fsl,err006687-workaround-present; status = "okay"; }; @@ -373,7 +370,6 @@ MX6QDL_PAD_RGMII_RX_CTL__RGMII_RX_CTL 0x1b030 /* Phy reset */ MX6QDL_PAD_EIM_D23__GPIO3_IO23 0x000b0 - MX6QDL_PAD_GPIO_6__ENET_IRQ 0x000b1 >; }; -- 2.39.5
