__FUNCTION__ is gcc-specific, use __func__

61711f8fd8 sm501: add uart support
This patch extends the sm501 mfd with 8250 uart support. We're currently
doing this in the board specific r2d-1 code already, but it would be nice to
do move things into the mfd since it's more chip specific than board specific.

3149be50d3 sm501: add support for the SM502 programmable PLL
SM502 has a programmable PLL which can provide the panel pixel clock instead
of the 288MHz and 336MHz PLLs.

1e27dbe774 SM501: Check SM501 ID register on initialisation
When binding the driver, check the ID register for a valid identity, in case
the SM501 is not functioning correctly.

819062219a SM501: Clock updates and checks
Ensure that the M1XCLK and MCLK are sourced from the same PLL (and refuse to
bind the driver if they are not).

Update the PCI to safe initialisation values, as 72MHz is the maximum clock
for 33MHz PCI bus mastering.

5136237bc3 SM501: Fix sm501_init_reg() mask/set order
The order of the set and mask operation in sm501_init_reg() was setting and
then masking the bits set.  Correct the order so that we do not end up with
288MHz SDRAM clocks on certain systems.

b6d6454fdb [PATCH] mfd: SM501 core driver
This driver provides the core functionality of the SM501, which is a
multi-function chip including two framebuffers, video acceleration, USB,
and many other peripheral blocks.

The driver exports a number of entries for the peripheral drivers to use.
