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

Currently, to define a GPIO number, we're using something like :
#define EFIKAMX_PCBID0 (2*32 + 16)
to define GPIO 3 16.
This is not really readable and it's error prone imho (note the 3 vs 2).
So, I'm introducing a new macro to define this in a better way. Now, the
code sample become :
#define EFIKAMX_PCBID0 IMX_GPIO_NR(3, 16)
v2:
- move to gpio.h
- add parens & spaces
- switch to IMX_GPIO_NR instead of MX51_GPIO_NR

Commit 124bf94a "ARM: imx: fix name for functions adding sdhci-esdhc-imx devices"
changed some devices and Kconfig entry and didn't change every places
it should have. It's breaking efikamx build. I've fixed 3ds Kconfig
entry as I believe it's broken there too.

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!

Since we're now using addruart to establish the debug mapping, we can
remove the io_pg_offst and phys_io members of struct machine_desc.
The various declarations were removed using the following script:
