[U-Boot] [PATCH V2 0/9] display and keypad support for nhk8815

[Alessandro Rubini]

This patch set implements display and keypad support. To turn the display
on I need the STMPE2401 port expander, set up as a separate driver in this
patch set.

It's the same set I sent for RFC on Oct 9 2009, with the requested
fixes.  I also added commit messages to each of them, and an initial
nhk-specific patch that was not submitted for RFC.

Detailed list of changes from V1 (as well as fixed message-id):

1/9 (nhk8815: fix i2c and other gpios at board_init time, not later):
     new patch, needed to apply the other ones.
     Please note that there is a block with local variables;
         I know it is generally not advisable but they are really of
         strictly local use, I think they deserve their limited scope.

2/9 (video: add amba-clcd prime-cell):
    include/amba_clcd.h: fixed white space (spaces before tab)
    better comments on the data structures

3/9 (include/nomadik.h: add physical address for cldc):
    unchanged

4/9 (drivers/misc: add stmpe2401 port extender and keypad controller):
    drivers/misc/stmpe2401.c: newlined all statements of if/else
    include/stmpe2401.h: white space fixes
    ====> Note: I did not turn it into a C structure, as those registers
          are I2C registers, so they are plain numbers, not offsets in
          an I/O memory region where I use readl/writel

5/9 (nhk8815.h: define we need stmpe):
    unchanged

6/9 (lcd: make 16bpp work):
    declared the new "d" pointer in new ifdef block. I dislike it, but
       my previous approach to avoid the ifdef was nacked. common/lcd.c is
       a mess, unfortunately.
    I made "./MAKEALL arm" and "./MAKEALL ppc" with no adverse effects.

7/9 (nhk8815: added keypad):
    layout (space, if blocks)
    removed extra __LINE__ temporary printouts
    added an header for local prototypes

8/9 (nhk8815: start lower in RAM, so the 800x480 frame buffer fits):
    changed the comment in config.mk.
    
9/9 (nhk8815: added lcd support):
    white space changes (tabified the structures)
    removed the __LINE__ temporary printouts
    used the header introduced in 7/9 for local prototypes
