2012-07-27ARM: Orion: DT support for IRQ and GPIO ControllersAndrew Lunn
Both IRQ and GPIO controllers can now be represented in DT. The IRQ controllers are setup first, and then the GPIO controllers. Interrupts for GPIO lines are placed directly after the main interrupts in the interrupt space.

Merge in branch already pulled. Fulfils dependancies needed by this patchset.
2012-07-27Merge tag 'spi-3.6' into v3.5-rc7-dt-v3Andrew Lunn
spi: Updates for 3.6 Since Grant is even more specacularly busy than usual for the time being I've been collecting SPI patches for him for this release - probably things will revert back to Grant before the next release. There's nothing too exciting here, mostly it's simple driver specific stuff: - Add spi: to the modaliases of SPI devices to provide namespacing. - A driver for AD-FMCOMMS1-EBZ. - DT binding for Orion. - Fixes and cleanups for i.MX, PL0022, OMAP and bitbang drivers. There may be a few more fixes I've missed, people keep sending me new things.

2012-07-25ARM: Orion: fix driver probe error handling with respect to clkSimon Baatz
The clk patches added code to get and enable clocks in the respective driver probe functions. If the probe function failed for some reason after enabling the clock, the clock was not disabled again in many cases.

2012-07-25ARM: Kirkwood: Fix PHY disable clk problemsSimon Baatz
Commit 98d9986 (ARM: Kirkwood: Replace clock gating) and the fix 5fb2ce (ARM: Kirkwood: clk_register_gate_fn: add fn assignment) introduced a custom variant of clock gating which allows to define a function to be called before gating the clock off. This is used to disable the SATA and PCIe PHYs if the respective clocks are unused after initialization. However, of these two drivers, the SATA driver may be compiled as a module. The driver re-enables the clocks at module init but the PHYs stay disabled. Since the custom clock gating disabled the PHYs when gating the clock off, it should also re-enable them when enabling the clock gate. This is done by adding a second function that may be used to enable the PHYs. Signed-off-by: Simon Baatz <gmbnomis@gmail.com> Signed-off-by: Andrew Lunn <andrew@lunn.ch>
2012-07-25ARM: Kirkwood: Ensure runit clock always ticks.Andrew Lunn
Marvell engineers tell us: It seems that many units use the RUNIT clock. SPI, UART, NAND, TWSI, ... So it's not possible to clock gate it. Currently the SPI, NAND and TWSI driver will clk_prepaure_enable() this clk, but since we have no idea what ... is, and turning this clk off results in a hard lock, unconditionally enable runit.

2012-07-23spi/bcm63xx: fix clock configuration selectionFlorian Fainelli
We are currently using an inferior or equal operator for comparing the transfer frequency with the clock frequency table. Because of this, we always end up selecting 20Mhz as a frequency, due to the inequality transfer hz <= 20 Mhz being always true. Fix this by reversing the inequality, which is how the comparison should be done. Signed-off-by: Florian Fainelli <florian@openwrt.org> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2012-07-22spi/omap2: mark omap2_mcspi_master_setup as __devinitArnd Bergmann
This warning recently appeared with omap2plus_defconfig: WARNING: drivers/spi/built-in.o(.devinit.text+0x3c4): Section mismatch in reference from the function omap2_mcspi_probe() to the function .init.text:omap2_mcspi_master_setup() The function __devinit omap2_mcspi_probe() references a function __init omap2_mcspi_master_setup(). If omap2_mcspi_master_setup is only used by omap2_mcspi_probe then annotate omap2_mcspi_master_setup with a matching annotation. The fix is obviously to mark the omap2_mcspi_master_setup function as __devinit, rather than __init.

2012-07-13x86/vsyscall: allow seccomp filter in vsyscall=emulateWill Drewry
If a seccomp filter program is installed, older static binaries and distributions with older libc implementations (glibc 2.13 and earlier) that rely on vsyscall use will be terminated regardless of the filter program policy when executing time, gettimeofday, or getcpu. This is only the case when vsyscall emulation is in use (vsyscall=emulate is the default). This patch emulates system call entry inside a vsyscall=emulate by populating regs->ax and regs->orig_ax with the system call number prior to calling into seccomp such that all seccomp-dependencies function normally. Additionally, system call return behavior is emulated in line with other vsyscall entrypoints for the trace/trap cases.

2012-07-13block: fix infinite loop in __getblk_slowJeff Moyer
Commit 080399aaaf35 ("block: don't mark buffers beyond end of disk as mapped") exposed a bug in __getblk_slow that causes mount to hang as it loops infinitely waiting for a buffer that lies beyond the end of the disk to become uptodate. The problem was initially reported by Torsten Hilbrich here: https://lkml.org/lkml/2012/6/18/54 and also reported independently here: http://www.sysresccd.org/forums/viewtopic.php?f=13&t=4511 and then Richard W.M. Jones and Marcos Mello noted a few separate bugzillas also associated with the same issue. This patch has been confirmed to fix: https://bugzilla.redhat.com/show_bug.cgi?id=835019 The main problem is here, in __getblk_slow: for (;;) { struct buffer_head * bh; int ret; bh = __find_get_block(bdev, block, size); if (bh) return bh; ret = grow_buffers(bdev, block, size); if (ret < 0) return NULL; if (ret == 0) free_more_memory(); } __find_get_block does not find the block, since it will not be marked as mapped, and so grow_buffers is called to fill in the buffers for the associated page. I believe the for (;;) loop is there primarily to retry in the case of memory pressure keeping grow_buffers from succeeding. However, we also continue to loop for other cases, like the block lying beond the end of the disk. So, the fix I came up with is to only loop when grow_buffers fails due to memory allocation issues (return value of 0). The attached patch was tested by myself, Torsten, and Rich, and was found to resolve the problem in call cases.

2012-07-13ARM: S3C24XX: Correct CAMIF interrupt definitionsSylwester Nawrocki
Properly define the CAMIF interrupt resources. This device have two interrupts - corresponding to the "codec" and "preview" data paths. IRQ_CAM is handled internally by the architecture and demultiplexed to IRQ_S3C2440_CAM_C and IRQ_S3C2440_CAM_P - these interrupts only should be handled in the driver.

2012-07-13ALSA: snd-usb: move calls to usb_set_interfaceDaniel Mack
The rework of the snd-usb endpoint logic moved the calls to snd_usb_set_interface() into the snd_usb_endpoint implemenation. This changed the order in which these calls are issued to the device, and thereby caused regressions for some webcams. Fix this by moving the calls back to pcm.c for now to make it work again and use snd_usb_endpoint_activate() to really tear down all remaining URBs in the flight, consequently fixing another regression caused by USB packets on the wire after altsetting 0 has been selected.

2012-07-12cpufreq / ACPI: Fix not loading acpi-cpufreq driver regressionThomas Renninger
Commit d640113fe80e45ebd4a5b420b introduced a regression on SMP systems where the processor core with ACPI id zero is disabled (typically should be the case because of hyperthreading). The regression got spread through stable kernels. On 3.0.X it got introduced via 3.0.18. Such platforms may be rare, but do exist. Look out for a disabled processor with acpi_id 0 in dmesg: ACPI: LAPIC (acpi_id[0x00] lapic_id[0x10] disabled) This problem has been observed on a: HP Proliant BL280c G6 blade This patch restricts the introduced workaround to platforms with nr_cpu_ids <= 1.

2012-07-12ARM: EXYNOS: register devices in 'need_restore' state for pm_domainsMarek Szyprowski
Commit ca1d72f033 ('PM / Domains: Make it possible to add devices to inactive domains') introduced possibility to add devices to inactive power domains and added pm_genpd_dev_need_restore() function which lets platform core to notify power domain core that the specified device must be restored (with its runtime_resume() callback) before first use. This patch adds the pm_genpd_dev_need_restore() call what brings back the suspend/resume behaviour for the client devices known from the previous power domain driver (removed by commit 91cfbd4ee0 - 'ARM: EXYNOS: Hook up power domains to generic power domain infrastructure'). Client device drivers relay on that suspend/resume behaviour, thus this patch fixes runtime pm operation for client devices.
