2014-07-09mmc: omap_hsmmc: switch default/idle pinctrl states in runtime hooksAndreas Fenkart
These are predefined states of the driver model. When not present, as if not set in the device tree, they become no-ops. Explicitly selecting the default state is not needed since the device core layer sets pin mux to "default" state before probe. This is not the simplest implementation, on AM335x at least, we could switch to idle at any point in the suspend hook, only the default state needs to be set before writing to the irq registers or an IRQ might get lost.

2014-07-09mmc: omap_hsmmc: abort runtime suspend if pending sdio irq detectedAndreas Fenkart
On multicores, an sdio irq handler could be running in parallel to runtime suspend. In the worst case it could be waiting for the spinlock held by the runtime suspend. When runtime suspend is complete and the functional clock (fclk) turned off, the irq handler will continue and cause a SIGBUS on the first register access.

2014-07-09mmc: omap_hsmmc: Enable SDIO interruptAndreas Fenkart
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.

2014-07-09mmc: mmci: Add Qcom specific rx_fifocnt logic.Srinivas Kandagatla
MCIFIFOCNT register behaviour on Qcom chips is very different than the other pl180 integrations. MCIFIFOCNT register contains the number of words that are still waiting to be transferred through the FIFO. It keeps decrementing once the host CPU reads the MCIFIFO. With the existing logic and the MCIFIFOCNT behaviour, mmci_pio_read will loop forever, as the FIFOCNT register will always return transfer size before reading the FIFO. Also the data sheet states that "This register is only useful for debug purposes and should not be used for normal operation since it does not reflect data which may or may not be in the pipeline". This patch implements a qcom specific get_rx_fifocnt function which is implemented based on status register flags. Based on qcom_fifo flag in variant data structure, the corresponding get_rx_fifocnt function is selected.

This resitriction is not applicable for other registers. Any subsequent writes to these register will be ignored until 3 MCLK have passed. One usec delay between two CMD register writes is not sufficient in the card identification phase where the CCLK is very low.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes Merge OMAP fixes from Tony Lindgren: Fixes for omaps for issues discovered during the merge window and enabling of a few features that had to wait for the driver dependencies to clear. The fixes included are: - Fix am43xx hard reset flags - Fix SoC detection for DRA722 - Fix CPU OPP table for omap5 - Fix legacy mux parser bug if requested muxname is a prefix of multiple mux entries - Fix qspi interrupt binding that relies on the irq crossbar that has not yet been enabled - Add missing phy_sel for am43x-epos-evm - Drop unused gic_init_irq() that is no longer needed And the enabling of features that had driver dependencies are: - Change dra7 to use Audio Tracking Logic clock instead of a fixed clock now that the clock driver for it has been merged - Enable off idle configuration for selected omaps as all the kernel dependencies for device tree based booting are finally merged as this is needed to get the automated PM tests working finally with device tree based booting - Add hwmod entry for ocp2scp3 for omap5 to get sata working as all the driver dependencies are now in the kernel and this patch fell through the cracks during the merge window * tag 'omap-for-v3.16/fixes-against-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: dts: dra7-evm: remove interrupt binding ARM: OMAP2+: Fix parser-bug in platform muxing code ARM: DTS: dra7/dra7xx-clocks: ATL related changes ARM: OMAP2+: drop unused function ARM: dts: am43x-epos-evm: Add Missing cpsw-phy-sel for am43x-epos-evm ARM: dts: omap5: Update CPU OPP table as per final production Manual ARM: DRA722: add detection of SoC information ARM: dts: Enable twl4030 off-idle configuration for selected omaps ARM: OMAP5: hwmod: Add ocp2scp3 and sata hwmods ARM: OMAP2+: hwmod: Change hardreset soc_ops for AM43XX

2014-07-04arm64: fix el2_setup check of CurrentELMarc Zyngier
The CurrentEL system register reports the Current Exception Level of the CPU. It doesn't say anything about the stack handling, and yet we compare it to PSR_MODE_EL2t and PSR_MODE_EL2h. It works by chance because PSR_MODE_EL2t happens to match the right bits, but that's otherwise a very bad idea. Just check for the EL value instead.

2014-07-04arm64: mm: Make icache synchronisation logic huge page awareSteve Capper
The __sync_icache_dcache routine will only flush the dcache for the first page of a compound page, potentially leading to stale icache data residing further on in a hugetlb page. This patch addresses this issue by taking into consideration the order of the page when flushing the dcache.

2014-07-04ALSA: hda - restore BCLK M/N value as per CDCLK for HSW/BDW display HDA ↵Mengdong Lin
controller For HSW/BDW display HD-A controller, hda_set_bclk() is defined to set BCLK by programming the M/N values as per the core display clock (CDCLK) queried from i915 display driver. And the audio driver will also set BCLK in azx_first_init() since the display driver can turn off the shared power in boot phase if only eDP is connected and M/N values will be lost and must be reprogrammed.
