Merge branch 'spear/pinctrl' into next/pinctrl
This is a rebased version of some contents of git://git.stlinux.com/spear/linux-2.6.git spear-v3.5 which was accidentally sent against linux-next rather than an -rc release. The commits are based on other changes in the spear/dt branch of the arm-soc tree that they depend on. * spear/pinctrl: SPEAr3xx: Add pinctrl support for boards SPEAr: Remove existing padmux support for SPEAr pinctrl: Add SPEAr3xx pinctrl drivers pinctrl: Add SPEAr pinctrl drivers Signed-off-by: Arnd Bergmann <arnd@arndb.de>

||
| SPEAr's pinmux nodes act as a container for an abitrary number of subnodes. Each | ||
| of these subnodes represents muxing for a pin, a group, or a list of pins or | ||
| groups. | ||
|
|
||
| The name of each subnode is not important; all subnodes should be enumerated | ||
| and processed purely based on their content. | ||
|
|
||
| Required subnode-properties: | ||
| - st,pins : An array of strings. Each string contains the name of a pin or | ||
| group. | ||
| - st,function: A string containing the name of the function to mux to the pin or | ||
| group. See the SPEAr's TRM to determine which are valid for each pin or group. | ||
|
|
||
| Valid values for group and function names can be found from looking at the | ||
| group and function arrays in driver files: | ||
| drivers/pinctrl/spear/pinctrl-spear3*0.c | ||
|
|
||
| Valid values for group names are: | ||
| For All SPEAr3xx machines: | ||
