* pinctrl: imx: move hard-coding data into device treeShawn Guo2013-04-091-1025/+507
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* Drivers: pinctrl: remove __dev* attributes.Greg Kroah-Hartman2013-01-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

* pinctrl: imx5: start numbering pad from 0Shawn Guo2012-09-031-245/+245
| | | | | | | | | | | Unlike imx6q pinctrl driver that starts nubmering pad from 0, imx5 pinctrl drivers number pad from 1. It causes problem/confusion when driver accesses imx51_pinctrl_pads array using pin ID as the index. Change imx51_pads and imx53_pads numbering start from 0.
