2008-10-16omap drivers: switch to standard GPIO callsDavid Brownell
This updates most of the OMAP drivers which are in mainline to switch to using the cross-platform GPIO calls instead of the older OMAP-specific ones. This is all fairly brainless/obvious stuff. Probably the most interesting bit is to observe that the omap-keypad code seems to now have a portable core that could work with non-OMAP matrix keypads. (That would improve with hardware IRQ debouncing enabled, of course...)

2008-09-02[MTD] mtdchar.c: Fix regression in MEMGETREGIONINFO ioctl()Zev Weiss
The MEMGETREGIONINFO ioctl() in mtdchar.c was clobbering user memory by overwriting more than intended, due the size of struct mtd_erase_region_info changing in commit 0ecbc81adfcb9f15f86b05ff576b342ce81bbef8 ('Support for auto locking flash on power up'). Fix avoids this by copying struct members one by one with put_user(), as there is no longer a convenient struct to use the size of as the length argument to copy_to_user().

We won't actually know how to handle them correctly; display the ID and ignore the chip. * Move the original block comment about the "legacy" chip ID scheme back next to the code to which it applies ... not next to the new JEDEC query code, which uses an entirely different strategy. * Don't print a guessed erasesize; /proc/mtd has the real value.

2008-07-25[MTD] [NAND] subpage read feature as a way to increase performance. Alexey Korolev
This patch enables NAND subpage read functionality. If upper layer drivers are requesting to read non page aligned data NAND subpage-read functionality reads the only whose ECC regions which include requested data when original code reads whole page. This significantly improves performance in many cases. Here are some digits : UBI volume mount time No subpage reads: 5.75 seconds Subpage read patch: 2.42 seconds Open/stat time for files on JFFS2 volume: No subpage read 0m 5.36s Subpage read 0m 2.88s Signed-off-by Alexey Korolev <akorolev@infradead.org> Acked-by: Artem Bityutskiy <dedekind@infradead.org> Acked-by: Jörn Engel <joern@logfs.org> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
