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>

The imx6qdl-sabreauto boards have a pcie slot so let's enable it. Tested on imx6dl-sabreauto with an atk9k wifi card; scanning works. There are unhandled differences for imx6qp but imx6qp-sabreauto.dts already contains a snippet explicitly disabling the &pcie node so that can be dealt with later.

2017-06-14ARM: dts: imx6-sabreauto: add reset-gpios property for max7310_bSteve Longerbeam1-0/+9
The reset pin to the port expander chip (MAX7310) is controlled by a gpio, so define a reset-gpios property to control it. There are three MAX7310's on the SabreAuto CPU card (max7310_[abc]), but all use the same pin for their reset. Since all can't acquire the same pin, assign it to max7310_b, that chip is needed by more functions (usb and adv7180).

2017-06-14ARM: dts: imx6-sabreauto: create i2cmux for i2c3Steve Longerbeam1-21/+44
The sabreauto uses a steering pin to select between the SDA signal on i2c3 bus, and a data-in pin for an SPI NOR chip. Use i2cmux to control this steering pin. Idle state of the i2cmux selects SPI NOR. This is not a classic way to use i2cmux, since one side of the mux selects something other than an i2c bus, but it works and is probably the cleanest solution. Note that if one thread is attempting to access SPI NOR while another thread is accessing i2c3, the SPI NOR access will fail since the i2cmux has selected the SDA pin rather than SPI NOR data-in. This couldn't be avoided in any case, the board is not designed to allow concurrent i2c3 and SPI NOR functions (and the default device-tree does not enable SPI NOR anyway). Devices hanging off i2c3 should now be defined under i2cmux, so that the steering pin can be properly controlled to access those devices. The port expanders (MAX7310) are thus moved into i2cmux.

2014-02-09ARM: dts: imx6qdl: make pinctrl nodes board specificShawn Guo1-12/+166
Currently, all pinctrl setting nodes are defined in <soc>.dtsi, so that boards that share the same pinctrl setting do not have to define it time and time again in <board>.dts. However, along with the devices and use cases being added continuously, the pinctrl setting nodes under iomuxc becomes more than expected. This bloats device tree blob for particular board unnecessarily since only a small subset of those pinctrl setting nodes will be used by the board. It impacts not only the DTB file size but also the run-time device tree lookup efficiency. The patch moves all the pinctrl data into individual boards as needed. With the changes, the pinctrl setting nodes becomes local to particular board, and it makes no sense to continue numbering the setting for given peripheral. Thus, all the pinctrl phandler name gets updated to have only peripheral name in there. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>

2013-08-22ARM: dts: imx: share pad macro names between imx6q and imx6dlShawn Guo1-0/+22
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>
