2012-04-05simple_open: automatically convert to simple_open()Stephen Boyd
Many users of debugfs copy the implementation of default_open() when they want to support a custom read/write function op. This leads to a proliferation of the default_open() implementation across the entire tree. Now that the common implementation has been consolidated into libfs we can replace all the users of this function with simple_open(). This replacement was done with the following semantic patch: <smpl> @ open @ identifier open_f != simple_open; identifier i, f; @@ -int open_f(struct inode *i, struct file *f) -{ ( -if (i->i_private) -f->private_data = i->i_private; | -f->private_data = i->i_private; ) -return 0; -} @ has_open depends on open @ identifier fops; identifier open.open_f; @@ struct file_operations fops = { ... -.open = open_f, +.open = simple_open, ... }; </smpl> [akpm@linux-foundation.org: checkpatch fixes] Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Al Viro <viro@zeniv.linux.org.uk> Cc: Julia Lawall <Julia.Lawall@lip6.fr> Acked-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2012-04-05ARM: fix __io macro for PCMCIARob Herring
With commit c334bc1 (ARM: make mach/io.h include optional), PCMCIA was broken. PCMCIA depends on __io() returning a valid i/o address, and most ARM platforms require IO_SPACE_LIMIT be set to 0xffffffff for PCMCIA. This needs a better fix with a fixed i/o address mapping, but for now we just restore things to the previous behavior. This fixes at91, omap1, pxa and sa11xx. pxa needs io.h if PCI is enabled, but PCMCIA is not. sa11xx already has IO_SPACE_LIMIT set to 0xffffffff, so it doesn't need an io.h.

clk_disable_unused is invoked when CONFIG_OMAP_RESET_CLOCKS=y. Since clk_disable_unused is called as lateinitcall, there can be more than a few workqueues executing off secondary CPU(s). The current code does the following: a) checks if clk is unused b) holds lock c) disables clk d) unlocks Between (a) and (b) being executed on CPU0, It is possible to have a driver executing on CPU1 which could do a get_sync->clk_get (and increase the use_count) of the clock which was just about to be disabled by clk_disable_unused. We ensure instead that the entire list traversal is protected by the lock allowing for parent child clock traversal which could be potentially be done by runtime operations to be safe as well.

If transceiver is attached to a MMC host of ES2.1 OMAP35xx, it seems 2.1.1.128 erratum doesn't apply and there is no data corruption, probably because of different signal timing.

With CONFIG_OMAP4_ERRATA_I688 enabled, omap2+ build was broken as below: arch/arm/kernel/io.c: In function '_memcpy_toio': arch/arm/kernel/io.c:29: error: implicit declaration of function 'outer_sync' make[1]: *** [arch/arm/kernel/io.o] Error 1 This was caused by commit 9f97da78 (Disintegrate asm/system.h for ARM).

2012-04-03ARM: OMAP2+: smsc911x: Add fixed board regulatorsRuss Dill
Initialize fixed regulators in the board files. Trying to do this in a generic way in gpmc-smsc911x.c gets messy as the regulator may be provided by drivers, such as twl4030, for some boards.

2012-04-03ARM: OMAP2+: smsc911x: Remove regulator support from gmpc-smsc911xRuss Dill
Adding in support for regulators here creates several headaches. - Boards that declare their own regulator cannot use this function. - Multiple calls to this function require special handling. - Boards that declare id's other than '0' need special handling. Now that there is a simple regulator_register_fixed, we can push this registration back into the board files.

If this function is called the first time with flags set, and the second time without flags set then the leftover flags from the first called will be used rather than the desired default flags.

2012-04-02ARM: fix lcd power build failure in collie_defconfigPaul Gortmaker
Commit 086ada54abaa4316e8603f02410fe8ebc9ba2de1 "FB: sa1100: remove global sa1100fb_.*_power function pointers" got rid of all instances but one in locomolcd.c -- which was conditional on CONFIG_SA1100_COLLIE. The associated .power field which replaces the global is populated in mach-sa1100/collie.c so move the assignment there, but make it conditional on the locomolcd support, so use CONFIG_BACKLIGHT_LOCOMO in that file.
