Russell King 7b4e9ced69 ARM: clcd: add method for describing display capabilities
The ARM CLCD PL110 controller in TFT mode provides two output formats
based on whether the controller is in 24bpp mode or not - either 5551
or 888.  PL111 augments this with a 444 and 565 modes.

Some implementations provide an external MUX on the PL110 output to
reassign the bits to achieve 565 mode.

Provide a system of capability flags to allow the CLCD driver to work
out what is supported by each panel and board, and therefore which
display formats are permitted.

Russell King 9c49e4ab84 ARM: clcd: use amba_part() to determine if we have a PL110 primecell
Instead of matching the entire peripheral ID, match against
just the part number using the amba_xxx() macros.

Russell King 99c796df94 VIDEO: amba clcd: don't disable an already disabled clock
Fix the clock enable/disable tracking in the AMBA CLCD driver so
that the driver doesn't try to disable an already disabled clock,
thereby causing the clock (if shared) to become unbalanced.

This resolves a problem with CLCD on LPC32xx ARM platforms.

Russell King 3f17522ce4 Video: ARM CLCD: Better fix for swapped IENB and CNTL registers
On PL111, as found on Realview and other platforms, these registers are
always arranged as CNTL then IENB.  On PL110, these registers are IENB
then CNTL, except on Versatile platforms.

Re-arrange the handling of these register swaps so that PL111 always
gets it right without resorting to ifdefs, leaving the only case needing
special handling being PL110 on Versatile.

Fill out amba/clcd.h with the PL110/PL111 register definition
differences in case someone tries to use the PL110 specific definitions
on PL111.

Catalin Marinas 243f196d57 [ARM] 3366/1: Allow the 16bpp mode configuration in the CLCD control register
Patch from Catalin Marinas

Starting with PL111, the 5551 or 565 modes can be configured in the
primecell's control register directly. This patch detects the required mode
and sets the correct value.

Russell King a62c80e559 [ARM] Move AMBA include files to include/linux/amba/
Since the ARM AMBA bus is used on MIPS as well as ARM, we need
to make the bus available for other architectures to use.  Move
the AMBA include files from include/asm-arm/hardware/ to
include/linux/amba/
