e16415313c pinctrl: imx: move hard-coding data into device tree
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.

49569646b2 Driver core __dev* removal patches
Here are the remaining __dev* removal patches against the 3.8-rc2 tree.
 All of these patches were previously sent to the subsystem maintainers,
 most of them were picked up and pushed to you, but there were a number
 that fell through the cracks, and new drivers were added during the
 merge window, so this series cleans up the rest of the instances of
 these markings.
 
 Third time's the charm...

Fixed up trivial conflict with the pinctrl pull in pinctrl-sirf.c.

150632b09a Drivers: pinctrl: remove __dev* attributes.
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.

b9cfddd90d pinctrl: imx5: fix GPIO_8 pad CAN1_RXCAN configuration
3 is an invalid value for the CAN1_IPP_IND_CANRX_SELECT_INPUT
register. Set it to 2, which correctly selects the GPIO_8 pad.

d5fff72db1 pinctrl: imx5: start numbering pad from 0
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.
