2012-11-17gpio: gpio-max710x: Support device tree probingRoland Stigge1-6/+6
For probing via device tree, we need to support the case without platform_data. In this case, chip.base is set to -1 for automatic numbering. Signed-off-by: Roland Stigge <stigge@antcom.de> Acked-by: Wolfram Sang <w.sang@pengutronix.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2012-11-17gpio: twl4030: Use only TWL4030_MODULE_LED for LED configurationPeter Ujfalusi1-17/+18
Avoid using the TWL4030_MODULE_PWMA/B as module ID. The LEDEN, PWMA ON/OFF and PWMB ON/OFF registers are in a continuous range starting from LED base. This is going to be helpful for further cleanup in the twl stack. No functional changes. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2012-11-08gpio: tegra: fix suspend/resume apisLaxman Dewangan1-5/+13
Following are changes done to fix the suspend/resume functionality of tegra gpio driver: - Protect suspend/resume callbacks with CONFIG_PM_SLEEP because CONFIG_PM doesn't actually enable any of the PM callbacks, it only allows to enable CONFIG_PM_SLEEP and CONFIG_PM_RUNTIME. This means if CONFIG_PM is used to protect system sleep callbacks then it may end up unreferenced if only runtime PM is enabled. - Fix the suspend/resume APIs declaration as per callback prototype.

2012-10-27GPIO: clps711x: use platform_device_unregister in gpio_clps711x_init()Wei Yongjun1-2/+1
platform_device_unregister() only calls platform_device_del() and platform_device_put(), thus use platform_device_unregister() to simplify the code. Also the documents in platform.c shows that platform_device_del and platform_device_put must _only_ be externally called in error cases. All other usage is a bug. dpatch engine is used to auto generate this patch.

2012-10-26gpio/tc3589x: convert to use the simple irqdomainLinus Walleij1-11/+9
The special checks for whether we have a base IRQ offset or not is surplus if we use the simple IRQ domain. The IRQ offset zero will be interpreted as a linear domain case. Plus this makes sure we allocate descriptors where need be, or warn if they are preallocated with SPARSE_IRQ.

2012-10-26gpio/em: convert to linear IRQ domainLinus Walleij1-39/+7
The code in the em driver seems to want to try to do the job of the linear IRQ domain (allocate descriptors and grab a virtual range). So why not just use the linear IRQ domain? The code is now cut down so we don't need isolated functions for this. Also note that we use irq_create_mapping() to make sure descriptors are allocated for these IRQs. Also fixed the FIXME to remove the domain after use. Cc: Grant Likely <grant.likely@secretlab.ca> Cc: Magnus Damm <damm@opensource.se> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2012-10-26gpio/mvebu: convert to use irq_domain_add_simple()Linus Walleij1-2/+2

2012-10-26gpio/tegra: convert to use linear irqdomainLinus Walleij1-9/+5
The Tegra driver tries to do the work of irq_domain_add_linear() by reserving a bunch of descriptors somewhere and keeping track of the base offset, then calling irq_domain_add_legacy(). Let's stop doing that and simply use the linear IRQ domain. For this to work: use irq_create_mapping() in the IRQ iterator so that the descriptors get allocated here.

2012-10-23gpiolib: Refactor gpio_exportRyan Mallon1-39/+46
The gpio_export function uses nested if statements and the status variable to handle the failure cases. This makes the function logic difficult to follow. Refactor the code to abort immediately on failure using goto. This makes the code slightly longer, but significantly reduces the nesting and number of split lines and makes the code easier to read.

2012-10-14x86, boot: Explicitly include autoconf.h for hostprogsMatt Fleming1-1/+2
The hostprogs need access to the CONFIG_* symbols found in include/generated/autoconf.h. But commit abbf1590de22 ("UAPI: Partition the header include path sets and add uapi/ header directories") replaced $(LINUXINCLUDE) with $(USERINCLUDE) which doesn't contain the necessary include paths. This has the undesirable effect of breaking the EFI boot stub because the #ifdef CONFIG_EFI_STUB code in arch/x86/boot/tools/build.c is never compiled. It should also be noted that because $(USERINCLUDE) isn't exported by the top-level Makefile it's actually empty in arch/x86/boot/Makefile. Cc: H.

git://git.infradead.org/users/dhowells/linux-headers Pull UAPI disintegration for include/linux/{,byteorder/}*.h from David Howells: "The patches contained herein do the following: (1) Remove kernel-only stuff in linux/ppp-comp.h from the UAPI. I checked this with Paul Mackerras before I created the patch and he suggested some extra bits to unexport. (2) Remove linux/blk_types.h entirely from the UAPI as none of it is userspace applicable, and remove from the UAPI that part of linux/fs.h that was the reason for linux/blk_types.h being exported in the first place. I discussed this with Jens Axboe before creating the patch. (3) The big patch of the series to disintegrate include/linux/*.h as a unit. This could be split up, though there would be collisions in moving stuff between the two Kbuild files when the parts are merged as that file is sorted alphabetically rather than being grouped by subsystem. Of this set of headers, 17 files have changed in the UAPI exported region since the 4th and only 8 since the 9th so there isn't much change in this area - as one might expect. It should be pretty obvious and straightforward if it does come to fixing up: stuff in __KERNEL__ guards stays where it is and stuff outside moves to the same file in the include/uapi/linux/ directory. If a new file appears then things get a bit more complicated as the "headers +=" line has to move to include/uapi/linux/Kbuild.

As suggested by Andrew Morton: This is a pet peeve of mine.

This commit was created by the following perl: while (<>) { while (/\\\s*$/) { $_ .= <>; } undef %selects if /^\s*config\s+/; if (/^\s+select\s+(\w+).*/) { if (defined($selects{$1})) { if ($selects{$1} eq $_) { print STDERR "Warning: removing duplicated $1 entry\n"; } else { print STDERR "Error: $1 differently selected\n". "\tOld: $selects{$1}\n". "\tNew: $_\n"; exit 1; } } $selects{$1} = $_; next; } if (%selects and (/^\s*$/ or /^\s+help/ or /^\s+---help---/ or /^endif/ or /^endchoice/)) { foreach $k (sort (keys %selects)) { print "$selects{$k}"; } undef %selects; } print; } if (%selects) { foreach $k (sort (keys %selects)) { print "$selects{$k}"; } } It found two duplicates: Warning: removing duplicated S5P_SETUP_MIPIPHY entry Warning: removing duplicated HARDIRQS_SW_RESEND entry and they are identical duplicates, hence the shrinkage in the diffstat of two lines. We have four testers reporting success of this change (Tony, Stephen, Linus and Sekhar.)

2012-10-13UAPI: Unexport linux/blk_types.hDavid Howells2-61/+59
It seems that was linux/blk_types.h incorrectly exported to fix up some missing bits required by the exported parts of linux/fs.h (READ, WRITE, READA, etc.). So unexport linux/blk_types.h and unexport the relevant bits of linux/fs.h.
