2015-07-24dts: imx53: fix sd card gpio polarity specified in device treeDong Aisheng1-2/+2
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: imx: use generic node name for fixed regulatorShawn Guo1-1/+4
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: imx53: make pinctrl nodes board specificShawn Guo1-34/+136
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>

2013-06-17ARM i.MX53: tqma53: rev 300 specific pin configurationPhilipp Zabel1-4/+4
I2S_MCLK is moved from pad GPIO19 to GPIO0, which can be muxed to the ssi_ext1 clock signal. #SYSTEM_DOWN is moved from pad GPIO0 to GPIO19. Add #PHY_RESET and LCD_CONTRAST.

2013-04-09pinctrl: imx: move hard-coding data into device treeShawn Guo1-15/+15
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 Guo1-1/+1
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 i.MX53: add dts for the TQ tqma53 moduleSascha Hauer1-0/+172
The tqma53 is an embedded module that has some features on board (e.g. emmc), but mostly just provides access to them on its interface. Going along with the imx53.dtsi, the tqma53.dtsi specifies the existing devices and their pinctrl for this module. All devices that are not on the module are disabled by default and need to be enabled in a baseboard DT.
