2015-07-24dts: imx6: fix sd card gpio polarity specified in device treeDong Aisheng
cd-gpios polarity should be changed to GPIO_ACTIVE_LOW and wp-gpios should be changed to GPIO_ACTIVE_HIGH. Otherwise, the SD may not work properly due to wrong polarity inversion specified in DT after switch to common parsing function mmc_of_parse().

2014-02-09ARM: dts: imx6: use generic node name for fixed regulatorShawn Guo
The device tree specification recommends that generic name should be used for nodes. So instead of naming those fixed regulator nodes arbitrarily, let's use the generic name 'regulator@num' for those nodes. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2014-02-09ARM: dts: imx6qdl: make pinctrl nodes board specificShawn Guo
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 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>

2013-04-09pinctrl: imx: move hard-coding data into device treeShawn Guo
Currently, all imx pinctrl drivers maintain a big array of struct imx_pin_reg which hard-codes data like register offset and mux mode setting for each pin function. Every time a new imx SoC support is added, we need to add such a big mount of data. With moving to single kernel build, it's only matter of time to be blamed on memory consuming. With DTC pre-processor support in place, the patch moves all these data into device tree by redefining the PIN_FUNC_ID in imxXX-pinfunc.h and changing the PIN_FUNC_ID parsing code a little bit. The pin id gets re-numbered based on mux register offset, or config register offset if the pin has no mux register, so that kernel can identify the pin id from register offsets provided by device tree. As a bonus point of the change, those arbitrary magic numbers standing for particular PIN_FUNC_ID in device tree sources are now replaced by macros to improve the readability of dts files.

2013-04-09ARM: imx: use #include for all device treesShawn Guo
Replace /include/ (dtc) with #include (C pre-processor) for all imx DT files, so that gcc -E handles the entire include tree, and hence any of those files can #include some other file e.g. for constant definitions. This allows future use of #defines and header files in order to define names for various constants, such as pinctrl settings. Use of those features will increase the readability of the device tree files. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-02-10ARM: dts: add dtsi for imx6q and imx6dlShawn Guo
Add dtsi for imx6q and imx6dl with non-common blocks moved into there. Major differences between imx6dl and imx6q: * Dual vs. Quad cores * single vs. dual IPU * 128 vs. 256 KB OCRAM * imx6q: ECSPI5, OpenVG (GC355), SATA * imx6dl: I2C4, PXP, EPDC, LCDIF * iomuxc/pads definition Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-02-10ARM: dts: rename imx6q.dtsi to imx6qdl.dtsiShawn Guo
i.MX6 Quad and i.MX6 DualLite is similar enough to share one dtsi file, so rename imx6q.dtsi to imx6qdl.dtsi preparing for the addition of imx6dl support. Another member of i.MX6 series i.MX6 SoloLite is different enough from the other two, so it will stand as a separate dtsi. That's why we rename to imx6qdl.dtsi not imx6.dtsi.

2013-02-10ARM: dts: imx: use nodes label in board dtsShawn Guo
Following omap3-evm.dts way, it changes all imx dts files to use label in board dts to refer to nodes defined by soc dtsi. Thus, the board dts files become easier to read and edit with the least indentation levels. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2012-10-16ARM: dts: imx6q-arm2: move NANDF_CS pins out of 'hog'Shawn Guo
Commit 9e3c0066 (ARM: dts: imx6q-arm2: add pinctrl for uart and enet) defines NANDF_CS pins as gpio in 'hog', assuming these two pins are always used by usdhc3 in gpio mode as card-detection and write-protection on ARM2 board. But it's not true. These pins are shared by usdhc3 and gpmi-nand. We should have the pins functional for gpmi-nand when usdhc3 is disabled. Move the pins out of 'hog', so that pins only work in gpio mode as CD and WP when usdhc3 is enabled, and otherwise they are available for gpmi-nand.
