2014-07-09mmc: omap_hsmmc: Pin remux workaround to support SDIO interrupt on AM335xAndreas Fenkart1-0/+53
The am335x can't detect pending cirq in PM runtime suspend. This patch reconfigures dat1 as a GPIO before going to suspend. SDIO interrupts are detected with the GPIO, the GPIO will only wake the module from suspend, SDIO irq detection will still happen through the IP block. Idea of remuxing the pins by Tony Lindgren.

2014-07-09mmc: omap_hsmmc: Enable SDIO interruptAndreas Fenkart1-0/+1
There have been various patches floating around for enabling the SDIO IRQ for hsmmc, but none of them ever got merged. Probably the reason for not merging the SDIO interrupt patches has been the lack of wake-up path for SDIO on some omaps that has also needed remuxing the SDIO DAT1 line to a GPIO making the patches complex. This patch adds the minimal SDIO IRQ support to hsmmc for omaps that do have the wake-up path. For those omaps, the DAT1 line need to have the wake-up enable bit set, and the wake-up interrupt is the same as for the MMC controller. This patch has been tested on am3730 es1.2 with mwifiex connected to MMC3 with mwifiex waking to Ethernet traffic from off-idle mode. Note that for omaps that do not have the SDIO wake-up path, this patch will not work for idle modes and further patches for remuxing DAT1 to GPIO are needed. Based on earlier patches [1][2] by David Vrabel <david.vrabel@csr.com>, Steve Sakoman <steve@sakoman.com> For now, only support SDIO interrupt if we are booted with a separate wake-irq configued via device tree. This is because omaps need the wake-irq for idle states, and some omaps need special quirks. And we don't want to add new legacy mux platform init code callbacks any longer as we are moving to DT based booting anyways. To use it, you need to specify the wake-irq using the interrupts-extended property.

2014-06-29ARM: 8076/1: mm: add support for HW coherent systems in PL310 cacheThomas Petazzoni1-0/+3
When a PL310 cache is used on a system that provides hardware coherency, the outer cache sync operation is useless, and can be skipped. Moreover, on some systems, it is harmful as it causes deadlocks between the Marvell coherency mechanism, the Marvell PCIe controller and the Cortex-A9. To avoid this, this commit introduces a new Device Tree property 'arm,io-coherent' for the L2 cache controller node, valid only for the PL310 cache. It identifies the usage of the PL310 cache in an I/O coherent configuration. Internally, it makes the driver disable the outer cache sync operation. Note that technically speaking, a fully coherent system wouldn't require any of the other .outer_cache operations. However, in practice, when booting secondary CPUs, these are not yet coherent, and therefore a set of cache maintenance operations are necessary at this point. This explains why we keep the other .outer_cache operations and only ->sync is disabled. While in theory any write to a PL310 register could cause the deadlock, in practice, disabling ->sync is sufficient to workaround the deadlock, since the other cache maintenance operations are only used in very specific situations. Contrary to previous versions of this patch, this new version does not simply NULL-ify the ->sync member, because the l2c_init_data structures are now 'const' and therefore cannot be modified, which is a good thing. Therefore, this patch introduces a separate l2c_init_data instance, called of_l2c310_coherent_data.

2014-06-25ALSA: hda - Adjust speaker HPF and add LED support for HP Spectre 13Takashi Iwai1-0/+5
HP Spectre 13 has the IDT 92HD95 codec, and BIOS seems to set the default high-pass filter in some "safer" range, which results in the very soft tone from the built-in speakers in contrast to Windows. Also, the mute LED control is missing, since 92HD95 codec still has no HP-specific fixups for GPIO setups. This patch adds these missing features: the HPF is adjusted by the vendor-specific verb, and the LED is set up from a DMI string (but with the default polarity = 0 assumption due to the incomplete BIOS on the given machine).

2014-06-23kernel/watchdog.c: print traces for all cpus on lockup detectionAaron Tomlin2-0/+22
A 'softlockup' is defined as a bug that causes the kernel to loop in kernel mode for more than a predefined period to time, without giving other tasks a chance to run. Currently, upon detection of this condition by the per-cpu watchdog task, debug information (including a stack trace) is sent to the system log. On some occasions, we have observed that the "victim" rather than the actual "culprit" (i.e. the owner/holder of the contended resource) is reported to the user. Often this information has proven to be insufficient to assist debugging efforts. To avoid loss of useful debug information, for architectures which support NMI, this patch makes it possible to improve soft lockup reporting. This is accomplished by issuing an NMI to each cpu to obtain a stack trace. If NMI is not supported we just revert back to the old method. A sysctl and boot-time parameter is available to toggle this feature.

Originally, I wanted to send this request during the merge window, but code checkers with very recent additions complained, so a few fixups were needed. So, some more time went by and I merged rc1 to get a stable base" So the "new driver" rule is really about drivers that people absolutely need for the kernel to work on new hardware, which is not so much the case for i2c. So I considered not pulling this, but eventually relented. Just for FYI: the whole (and only) point of "new drivers" is not that new drivers cannot regress things (they can, and they have - by triggering badly tested code on machines that never triggered that code before), but because they can bring to life machines that otherwise wouldn't be useful at all without the drivers. So the new driver rule is for essential things that actual consumers would care about, ie devices like networking or disk drivers that matter to normal people (not server people - they run old kernels anyway, so mainlining new drivers is irrelevant for them). * 'i2c/for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: i2c: sun6-p2wi: fix call to snprintf i2c: rk3x: add NULL entry to the end of_device_id array i2c: sun6i-p2wi: use proper return value in probe i2c: sunxi: add P2WI (Push/Pull 2 Wire Interface) controller support i2c: sunxi: add P2WI DT bindings documentation i2c: rk3x: add driver for Rockchip RK3xxx SoC I2C adapter

Specifics: - Fix for an ia64 regression introduced during the 3.11 cycle by a commit that modified the hardware initialization ordering and made device discovery fail on some systems. - Fix for a build problem on systems where the cpufreq-cpu0 driver is built-in and the cpu-thermal driver is modular from Arnd Bergmann. - Fix for a recently introduced computational mistake in the intel_pstate driver that leads to excessive rounding errors from Doug Smythies. - Fix for a failure code path in cpufreq_update_policy() that fails to unlock the locks acquired previously from Aaron Plattner. - Fix for the cpuidle mvebu driver to use shorter state names which will prevent the sysfs interface from returning mangled strings. From Gregory Clement. - ACPI LPSS driver fix to make sure that the I2C controllers included in BayTrail SoCs are not held in the reset state while they are being probed from Mika Westerberg. - New kernel command line arguments making it possible to build kernel images with hibernation and kASLR included at the same time and to select which of them will be used via the command line (they are still functionally mutually exclusive, though).

After commits 890676c6 (kbuild: Use relative path when building in the source tree) and 9da0763b (kbuild: Use relative path when building in a subdir of the source tree), the $(srctree) variable can be a relative path.
