2013-04-09pinctrl: imx: move hard-coding data into device treeShawn Guo1-102/+103
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>

2012-12-13Merge tag 'dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-socLinus Torvalds1-21/+71
Pull ARM SoC device tree conversions and enablement from Olof Johansson: "Continued device tree conversion and enablement across a number of platforms; Kirkwood, tegra, i.MX, Exynos, zynq and a couple of other smaller series as well. ux500 has seen continued conversion for platforms. Several platforms have seen pinctrl-via-devicetree conversions for simpler multiplatform. Tegra is adding data for new devices/drivers, and Exynos has a bunch of new bindings and devices added as well. So, pretty much the same progression in the right direction as the last few releases."

2012-11-16ARM i.MX dts: Consistently add labels to devicenodesSascha Hauer1-21/+21
Having labels before each node allows board bindings to reference to nodes by using the &nodename {} notation. This way boards do not have to resemble the whole devicetree layout. Due to less indention needed the board files also get better readability. Since the label make the documentation behind the nodes unnecessary it is removed.

2012-10-15i2c: imx: remove cpu_is_xxx by using platform_device_idShawn Guo1-3/+3
This is some amount of work left/forgot from device tree conversion. Instead of checking cpu_is_xxx to determine the controller type, the driver should use platform_device_id, which should match the device tree compatible string. The patch changes the driver to use platform_device_id rather than cpu_is_xxx to determine the controller type/version. It also updates the platform code and device tree source accordingly. As the result, mach/hardware.h inclusion gets removed from the driver.
