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
Alessandro Rubini (9): nhk8815: change the order of initialization video: add amba-clcd prime-cell include/nomadik.h: add physical address for cldc drivers/misc: add stmpe2401 port extender and keypad controller nhk8815.h: define we need stmpe lcd: make 16bpp work nhk8815: added keypad nhk8815: start lower in RAM, so the 800x480 frame buffer fits nhk8815: added lcd support
