Pull "urgent onenand file system corruption fix for n900" from Tony Lindgren: Last minute urgent pull request to prevent file system corruption on Nokia N900. Looks like we have a GPMC bus timing bug that has gone unnoticed because of bootloader configured registers until few days ago. We are not detecting the onenand clock rate properly unless we have CONFIG_OMAP_GPMC_DEBUG set and this causes onenand corruption that can be easily be reproduced. There seems to be also an additional bug still lurking around for onenand corruption. But that is still being investigated and it does not seem to be GPMC timings related. Meanwhile, it would be good to get this fix into v4.4 to prevent wrong timings from corrupting onenand. * tag 'omap-for-v4.4/onenand-corruption' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: OMAP2+: Fix onenand rate detection to avoid filesystem corruption

dts: vt8500: Add SDHC node to DTS file for WM8650

ARM: Fix broken USB support in multi_v7_defconfig for sunxi devices

2016-01-07T15:02:19Z

Commit 69fb4dcada77 ("power: Add an axp20x-usb-power driver") introduced a new driver for the USB power supply used on various Allwinner based SBCs. However, the driver was not added to multi_v7_defconfig which breaks USB support for some boards (e.g. LeMaker BananaPi) as the kernel will now turn off the USB power supply during boot by default if the driver isn't present. (This was not the case in linux 4.3 or lower where the USB power was always left on.) Hence, add the driver to multi_v7_defconfig in order to keep USB support working on those boards that require it.

kvm: x86: only channel 0 of the i8254 is linked to the HPET

2016-01-07T12:50:38Z

While setting the KVM PIT counters in 'kvm_pit_load_count', if 'hpet_legacy_start' is set, the function disables the timer on channel[0], instead of the respective index 'channel'. This is because channels 1-3 are not linked to the HPET. Fix the caller to only activate the special HPET processing for channel 0.

ARM: versatile: fix MMC/SD interrupt assignment

2016-01-07T05:32:19Z

Commit 0976c946a610d06e907335b7a3afa6db046f8e1b "arm/versatile: Fix versatile irq specifications" has an off-by-one error on the Versatile AB that has been regressing the Versatile AB hardware for some time. However it seems like the interrupt assignments have never been correct and I have now adjusted them according to the specification. The masks for the valid interrupts made it impossible to assign the right SIC interrupt for the MMCI, so I went in and fixed these to correspond to the specifications, and added references if anyone wants to double-check. Due to the Versatile PB including the Versatile AB as a base DTS file, we need to override and correct some values to correspond to the actual changes in the hardware. For the Versatile PB I don't think the IRQ line assignment for MMCI has ever been correct for either of the two MMCI blocks. It would be nice if someone with the physical PB board could test this. Patch tested on the Versatile AB, QEMU for Versatile AB and QEMU for Versatile PB.

ARM: nomadik: set latencies to 8 cycles

2016-01-07T05:30:13Z

The Nomadik has sporadic crashes because of these latencies, setting them to max makes the platform work nicely, so use this values for now. These latencies were set to 2 since the Nomadik platform was merged, but I suspect they never took effect until the right size and associativity for the cache was specified in the device tree and that is why the crash comes now.
