Ensure that the i2c buses are reported to userspace (for example to
i2cdetect) in the same order as they are numbered in the SoC's
documentation by adding aliases to the devicetree.

The MUX bits for esdhc_{a,c,d}_sel are shifted by one bit within CSCMR1,
because esdhc_b_sel (ESDHC3_CLK_SEL in the Reference Manual) is extended
by one bit.

i.MX50 does not have a periph_apm clock. Instead, the main bus clock
(a.k.a. periph_clk) comes directly from a MUX between pll1_sw, pll2_sw,
pll3_sw, and lp_apm.

There are a few differences between the i.MX50 clock tree and those of
i.MX51 and i.MX53 that are not yet handled in clk-imx51-imx53.c. This

Because I'm touching a critical driver that's shared between all i.MX5
SoC's, I'd prefer to get a confirmation from someone
Contrary to the description, the first parameter (n) should not be
passed as a pointer, but directly as an lvalue. This is possible because
do_div is a macro.

UNAME26 is a mechanism to report Linux's version as 2.6.x, for
compatibility with old/broken software. Because of the way it is
implemented, it needs to be adjusted to handle version 5.0.

This patchset adds the necessary bits to wii.dts to enable interrupt
support in the GPIO controller, and defines two GPIO-based buttons,
the POWER button and the EJECT button.
I will send another patchset which will implement interrupt support in
the GPIO driver (gpio-hlwd.c).

The Wii has POWER and EJECT buttons, which are connected through
normalization logic to the GPIO controller (the length of an assertion
of these signals is always the same, regardless of how long the user
pressed the buttons).

The Hollywood GPIO controller is connected to the Hollywood PIC ()
at IRQs 10 and 11; IRQ 10 for GPIO lines that are configured for access
by the PPC, 11 for GPIO lines that are configured for access by the
ARM926.

This patch implements level-triggered IRQs in the Hollywood GPIO driver.
Edge triggered interrupts are not supported in this GPIO controller, so
I moved their emulation into a separate patch.
