Sascha Hauer ee1ae4d7b1 ARM i.MX51: Full iomux support
This iomux file has been constructed from the Freescale pinmux tool.
It contains all pins from the tool, but the datasheet lists some
configurations not present in the tool, these are not yet added.

Lothar Waßmann 96f3e25684 MXC IOMUX-V3 replace struct pad_desc with bitmapped cookie (step 2)
This patch actually replaces the 'struct pad_desc' with a u64 cookie
to facilitate adding platform specific pad_ctrl settings to an
existing pad definition.

So, instead of:
	iomux_v3_cfg_t power_key = MX51_PAD_EIM_A27__GPIO_2_21;
	power_key.pad_ctrl = MX51_GPIO_PAD_CTRL_2;
	mxc_iomux_v3_setup_pad(&power_key);
one can write:
	mxc_iomux_v3_setup_pad((MX51_PAD_EIM_A27__GPIO_2_21 & ~MUX_PAD_CTRL_MASK) | MX51_GPIO_PAD_CTRL_2);

Patch applies to branch 'imx-for-2.6.38' of git://git.pengutronix.de/git/imx/linux-2.6

Lothar Waßmann 8f5260c8c1 ARM: i.MX IOMUX-V3 replace struct pad_desc with bitmapped cookie
The following patch is a first step to convert the 'struct pad_desc'
to a bitmapped cookie to facilitate adding platform specific pullup or
drive strength definitions to existing pad definitions without need to
rewrite the complete pad def.

The patch wraps 'struct pad_desc' in an opaque data type and
introduces macros to access the individual members.
This patch does not constitute any functional change!

Jason Wang 426ab49b33 mxc/iomux: add GPIO bank offset for iomux v3 platforms
These GPIO bank offsets are useful when define a gpio number.
E.G. when GPIO PORTC pin 6 is used for irq request pin of external
expanding device, we can define it like:
  #define EXP_PARENT_IRQ_PIN (GPIO_PORTC + 6)

Sascha Hauer 654166d687 mxc: iomux v3: remove resource handling
The current model does not allow to put a pad into different modes
once a pins is allocated. Remove the resource handling.

Sascha Hauer 997d74b18a MXC iomux-v3: Fix defines for PAD_CTL registers
The old defines leaked in from an old version of the patch.
Change the defines to match the register layout of the iomuxer.

Sascha Hauer bca6ef1e53 MXC: Add iomux support for MX35 SoCs
This iomux is called iomux-v3 in the tree because it is the third known
incarnation of MXC iomuxers. It is not only found on the MX35 but also
on the MX51 and probably others.
