2014-02-09ARM: dts: imx: pinfunc: add MX6QDL_PAD_GPIO_6__ENET_IRQTroy Kisky
From "Chip Errata for the i.MX 6Dual/6Quad" ERR006687 ENET: Only the ENET wake-up interrupt request can wake the system from Wait mode. The ENET block generates many interrupts. Only one of these interrupt lines is connected to the General Power Controller (GPC) block, but a logical OR of all of the ENET interrupts is connected to the General Interrupt Controller (GIC). When the system enters Wait mode, a normal RX Done or TX Done does not wake up the system because the GPC cannot see this interrupt. This impacts performance of the ENET block because its interrupts are serviced only when the chip exits Wait mode due to an interrupt from some other wake-up source. Adding MX6QDL_PAD_GPIO_6__ENET_IRQ is the 1st step to workaround this problem. The input reg is set to 0x3c to set IOMUX_OBSRV_MUX1 to ENET_IRQ. The mux reg value is 0x11, so that the observable mux is routed to this pin and to the gpio controller(sion bit). These magic values come from Ranjani Vaidyanathan's patch: "ENGR00257847-1 MX6Q/DL-Fix Ethernet performance issue when WAIT mode is active" Signed-off-by: Troy Kisky <troy.kisky@boundarydevices.com> CC: Ranjani Vaidyanathan <ra5478@freescale.com> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>

The solo/duallite reference manual does not mention this setting, but it works. Signed-off-by: Troy Kisky <troy.kisky@boundarydevices.com> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-08-22ARM: dts: imx: share pad macro names between imx6q and imx6dlShawn Guo
The imx6q and imx6dl are two pin-to-pin compatible SoCs. The same board design can work with either chip plugged into the socket, e.g. sabresd and sabreauto boards. We currently define pin groups in imx6q.dtsi and imx6dl.dtsi respectively because the pad macro names are different between two chips. This brings a maintenance burden on having the same label point to the same pin group defined in two places. The patch replaces prefix MX6Q_ and MX6DL_ with MX6QDL_ for both SoCs pad macro names. Then the pin groups becomes completely common between imx6q and imx6dl and can just be moved into imx6qdl.dtsi, so that the long term maintenance of imx6q/dt pin settings becomes easier. Unfortunately, the change brings some dramatic diff stat, but it's all about DTS file, and the ultimate net diff stat is good. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-08-22ARM: dts: imx6q{dl}: add DTE pads for uartHuang Shijie
The uart2 in the imx6q-arm2 board is used as a DTE uart, this patch adds the necessary DTE pads for uart2. Signed-off-by: Huang Shijie <b32955@freescale.com> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-04-09pinctrl: add pinctrl driver for imx6dlShawn Guo
The imx6dl is a derivative of imx6q with very limited difference. These two SoCs are so compatible that they can be handled as one platform in software. That said, we will not have target SOC_IMX6DL but just reusing SOC_IMX6Q. That's why the pinctrl-imx6dl driver is added here with symbol PINCTRL_IMX6Q controlling the build of it.
