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

Arnaud Patard (Rtp) 28d6a7a2f3 imx: fix iomux v3
Commit "ARM: i.MX IOMUX-V3 replace struct pad_desc with bitmapped cookie"
(b705cb4d42e95a4a43a8945571c8613e71526c3d) introduced a typo which was
preventing my efikamx to boot. This patch is fixing that.

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!

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 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.
