* gpio: viperboard: Remove duplicate code to set gpio->gpiob_valAxel Lin2013-03-271-4/+0
| | | | | | | | | | Set it once is enough, and it's done in vprbrd_gpiob_set() which is called by vprbrd_gpiob_direction_output().

* gpio-ich: Check for pin availability at request timeJean Delvare2013-03-271-12/+3
| | | | | | | | | | | | | Stop checking for pin availability in direction and get functions. These functions can be called repeatedly, so checking every time is bad for performance. Now that requesting GPIO pins is no longer optional, checking for availability at pin request time is enough.

* gpio/em: Add Device Tree supportMagnus Damm2013-03-061-3/+42
| | | | | | | | | | | | | Update the Emma Mobile GPIO driver to add DT support. The patch simply adds a two-cell xlate function and updates the probe code to allow configuration via DT using the "ngpios" property plus OF id in the same style as gpio-mvebu.c. The code is also adjusted to use postcore_initcall() to force early setup. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
* gpio/omap: warn if bank is not enabled on setting irq typeJon Hunter2013-03-061-0/+3
| | | | | | | | | | | | | | | For OMAP devices, if a gpio is being used as an interrupt source but has not been requested by calling gpio_request(), a call to request_irq() may cause the kernel hang because the gpio bank may be disabled and hence the register access will fail. To prevent such hangs, test for this case and warn if this is detected.

* gpio/omap: convert gpio irq domain to linear mappingJon Hunter2013-03-061-41/+31
| | | | | | | | | | | | | | | | | | | Currently the OMAP GPIO driver uses a legacy mapping for the GPIO IRQ domain. This is not necessary because we do not need to assign a specific interrupt number to the GPIO IRQ domain. Therefore, convert the OMAP GPIO driver to use a linear mapping instead. Please note that this also allows to simplify the logic in the OMAP gpio_irq_handler() routine, by using irq_find_mapping() to obtain the virtual irq number from the GPIO bank and bank index.

* gpio/gpio-ich: fix ichx_gpio_check_available() return what callers expectMika Westerberg2013-03-021-2/+2
| | | | | | | | | | | | | | | | | ichx_gpio_check_available() returns either 0 or -ENXIO depending on whether the given GPIO is available or not. However, callers of this function treat the return value as boolean: ... if (!ichx_gpio_check_available(gpio, nr)) return -ENXIO; which erroneusly fails when the GPIO is available and not vice versa. Fix this by making the function return boolean as expected by the callers. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

With regards to ghes-edac, this fixes a longstanding BZ at Red Hat that happens with Nehalem and Sandy Bridge CPUs: when both GHES and i7core_edac or sb_edac are running, the error reports are unpredictable, as both BIOS and OS race to access the registers. With ghes-edac, the EDAC core will refuse to register any other concurrent memory error driver. This patchset moves the ghes struct definitions to a separate header file (include/acpi/ghes.h) and adds 3 hooks at apei/ghes.c to register/unregister and to report errors via ghes-edac.

There are two reasons for that: 1) Each driver assumes that it is the only one registering at the EDAC core, as it is driver's responsibility to number the memory controllers, and all of them start from 0; 2) If BIOS is handling the memory errors, the OS can't also be doing it, as one will mangle with the other. So, we need to add an module owner's lock at the EDAC core, in order to avoid having two different modules handling memory errors at the same time. The best way for doing this lock seems to use the driver's name, as this is unique, and won't require changes on every driver. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

It seems to be partially caused by the BIOS and partially by the driver. The i3200_edac current logic would be working fine if the BIOS were disabling the unused second channel when just one DIMM is connected, in order to do power-saving, as recommended on this chipset's datasheet. However, the BIOS on this particular machine doesn't do it: [ 16.741421] EDAC DEBUG: how_many_channels: In dual channel mode [ 16.741424] EDAC DEBUG: how_many_channels: 2 DIMMS per channel enabled So, the driver were assuming that 2 channels are enabled (well, they are, but the second is unused). Combined with that, I found two issues at the logic that creates the EDAC data, that were failing when the two channels are not equally filled (AFAICT, that happens only when just 1 DIMM is plugged). The first one is that a 0 at DRB means that nothing is filled. The driver's logic, however, do some calculation with that. The second one is that the logic that fills the DIMM data currently assumes that both channels are equally filled. I tested the system already with the current configuration and my patch and it is now working fine. So, for a 2R single DIMM 2Gb memory at dimm slot 01 (channel 0), it is now displaying: [ 16.741406] EDAC DEBUG: i3200_get_drbs: drb[0][0] = 16, drb[1][0] = 0 [ 16.741410] EDAC DEBUG: i3200_get_drbs: drb[0][1] = 32, drb[1][1] = 0 [ 16.741413] EDAC DEBUG: i3200_get_drbs: drb[0][2] = 32, drb[1][2] = 0 [ 16.741416] EDAC DEBUG: i3200_get_drbs: drb[0][3] = 32, drb[1][3] = 0 ...

But there was a more subtle conflict I missed: the driver uses MAX_USER_RT_PRIO, but commit 8bd75c77b7c6 ("sched/rt: Move rt specific bits into new header file") had moved that define from <linux/sched.h> to <linux/sched/rt.h>. Which caused this build failure: drivers/thermal/intel_powerclamp.c: In function ‘clamp_thread’: drivers/thermal/intel_powerclamp.c:360:21: error: ‘MAX_USER_RT_PRIO’ undeclared (first use in this function) drivers/thermal/intel_powerclamp.c:360:21: note: each undeclared identifier is reported only once for each function it appears in And because I don't do a full "make allmodconfig" build after each pull, I didn't notice until too late.

Notable changes are: - More devices get moved out of board files into device tree descriptions. The remaining devices listed in there have patches that will get sent for 3.10, after which we can remove a lot of the board files entirely. We are doing the pinctrl and mmc drivers here, ethernet and PCI still remain. - SMP support for mvebu is improved with support for the local interrupt controller. - The Guruplug board file gets replaced with a DT description. Unfortunately, the dependency on the MMC tree turned out to be a much larger problem than expected, when the MMC maintainer rebased the patches in his tree that all of the patches in this branch are based on, which caused merge conflicts between the new and old versions of those patches. To work around the merge conflicts, this branch rebases all patches on top of the respective MMC patches that did get merged into 3.9. The patches are all identical to the versions that were part of linux-next, but have a new commit date." * tag 'late-mvebu-rebased' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (90 commits) arm: mvebu: enable the SD card slot on Armada 370 Reference Design board ARM: kirkwood: topkick: init mvsdio via DT ARM: kirkwood: nsa310: convert to pinctrl ARM: Kirkwood: topkick: Enable i2c bus.
