There are 2 versions of the timrot on Freescale MXS-based SoCs.
The v1 on MX23 only gets 16 bits counter, while v2 on MX28
extends the counter to 32 bits.
The implementation uses two timers, one for clock_event and
another for clocksource. MX28 uses timrot 0 and 1, while MX23
uses 0 and 2.

This iomux file has been constructed from the Freescale pinmux tool.

configurations not present in the tool, these are not yet added.

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

When building as module:
ERROR: "cpufreq_gov_performance" [arch/arm/plat-mxc/cpufreq.ko] undefined!
WARNING: modpost: Found 1 section mismatch(es).
To see full details build your kernel with:
'make CONFIG_DEBUG_SECTION_MISMATCH=y'
make[1]: *** [__modpost] Error 1
make: *** [modules] Error 2
It's due to the driver using CPUFREQ_DEFAULT_GOVERNOR, even it should not
(see commit 8122c6cea0 in Linus tree), so
remove it.

gic_set_cpu will directly use irq_desc[]. If CONFIG_SPARSE_IRQ is
enabled, there is no irq_desc[]. So we need use irq_to_desc(irq) to
get the descriptor for irq.

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

it should have. It's breaking efikamx build. I've fixed 3ds Kconfig

In commit 2c20b9f (ARM: mx25: dynamically allocate mxc-ehci devices) I
changed the offset to the value specified in the reference manual
intending to test this change on hardware. This slipped through and now
prooved to be wrong. So fix it and add a comment about the
documentation being wrong.
