2019-04-11ARM: dts: imx: Fix the AR803X phy-modeFabio Estevam1-1/+1
Commit 6d4cd041f0af ("net: phy: at803x: disable delay only for RGMII mode") exposed an issue on imx DTS files using AR8031/AR8035 PHYs. The end result is that the boards can no longer obtain an IP address via UDHCP, for example. Quoting Andrew Lunn: "The problem here is, all the DTs were broken since day 0. However, because the PHY driver was also broken, nobody noticed and it worked. Now that the PHY driver has been fixed, all the bugs in the DTs now become an issue" To fix this problem, the phy-mode property needs to be "rgmii-id", which has the following meaning as per Documentation/devicetree/bindings/net/ethernet.txt: "RGMII with internal RX and TX delays provided by the PHY, the MAC should not add the RX or TX delays in this case)" Tested on imx6-sabresd, imx6sx-sdb and imx7d-pico boards with successfully restored networking. Based on the initial submission from Steve Twiss for the imx6qdl-sabresd.

2018-12-10ARM: dts: imx6qdl: Fix memory node duplicationMarco Franchi1-0/+1
Boards based on imx6qdl have duplicate memory nodes: - One coming from the board device tree file: memory@ - One coming from the imx6qdl.dtsi file. Fix the duplication by removing the memory node from the imx6qdl.dtsi file and by adding 'device_type = "memory";' in the board Device Tree. Converted using the following command: perl -p0777i -e 's/memory\@10000000 \{\n/memory\@10000000 \{\n\t\tdevice_type = \"memory\";\n/m' `find ./arch/arm/boot/dts -name "imx6*"`` Reported-by: Rob Herring <robh@kernel.org> Signed-off-by: Marco Franchi <marco.franchi@nxp.com> Reviewed-by: Fabio Estevam <festevam@gmail.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>

2017-06-07ARM: dts: imx6: Fix PCI GPIO reset polarityFabio Estevam1-1/+1
The imx6 PCI driver ignores the GPIO polarity from 'reset-gpio' and considers that the PCI reset is active low, unless the property 'reset-gpio-active-high' is present. Fix the device tree description by explicitly passing the 'GPIO_ACTIVE_LOW' flag to the 'reset-gpio' property.

Since commit b36581df7e78 ("spi: imx: Using existing properties for chipselects") the device tree property 'fsl,spi-num-chipselects' is unused and it is already marked as obsolete in device tree binding documentation. Remove the property from the existing DTS files to avoid its reoccurence on copying.

As of commit 1006ed7e1b258dac ("serial: imx: Use generic uart-has-rtscts DT property"), the Freescale IMX UART driver recognizes the generic "uart-has-rtscts" DT property, deprecating the vendor-specific "fsl,uart-has-rtscts" DT property. Hence replace the latter by the former in all DTS files. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
