The include/dt-bindings/clock/ath79-clk.h header file is introduced so we can use symbolic identifiers for SoC clocks.

2016-05-13MIPS: dts: qca: ar9132: use short references for dt nodesAntony Pavlov
Here are some Sascha Hauer's arguments for using aliases in the dts files: - using aliases reduces the number of indentations in dts files; - dts files become independent of the layout of the dtsi files (it becomes possible to introduce another bus {} hierarchy between a toplevel bus and the devices when you have to); - less chances for typos. if &i2c2 does not exist you get an error. If instead you duplicate the whole path in the dts file a typo in the path will just create another node.

2016-05-13MIPS: dts: qca: ar9132_tl_wr1043nd_v1.dts: drop unused alias nodeAntony Pavlov
The TP-LINK TL-WR1043ND board has only one serial port, so replacing the default of 0 with 0 does nothing useful. Moreover, the correct name for aliases node is "aliases" not "alias". An overview of the "aliases" node usage can be found on the device tree usage page at devicetree.org [1]. Also please see chapter 3.3 ("Aliases node") of the ePAPR 1.1 [2].

Broadcom ARM home routers store SPROM content in NVRAM just like MIPS ones. To share SPROM code we need to move it out of arch/mips/ to some common place. We already have bcm47xx_nvram in firmware path and SPROM should fit there as well. This driver is responsible for parsing SoC configuration data into a struct shared between ssb and bcma buses. This was tested with BCM4706 & BCM5357C0 (BCM47XX) and BCM4708A0 (ARCH_BCM_5301X).

2016-05-13MIPS: highmem: Turn flush_cache_kmaps into a no-op.Ralf Baechle
It was calling flush_cache_all() which is a no-op since a long time anyway and which was overkill in the old days when it was actually doing something because only the D-cache needs to be flushed, never the I-cache, never the S-cache. Since however highmem on MIPS is still only supported on processors that don't suffer from cache aliases, we could turn flush_cache_kmaps() into a no-op - but for paranoia's sake we rather make it BUG_ON(cpu_has_dc_aliases()).

duplex. Happened when the Playback (or Capture) is running continuously and Capture (or Playback) is restarted (xrun, manual stop/start...) Since the RX (or TX) FIFO are only reset when the whole SSI is disabled, pending samples from previous capture (or playback) session may still be present. They must be erased to not introduce channel slipping. FIFO Clear register fields are documented in IMX51, IMX35 reference manual.

2016-05-13ASoC: fsl_ssi: Fix channel slipping in Playback at startupArnaud Mouiche
Previously, SCR.SSIEN and SCR.TE were enabled at once if no capture stream was also running. This may not give a chance for the DMA to write the first sample in TX FIFO before the streaming starts on the PCM bus, inserting void samples first. Those void samples are then responsible for slipping the channels.

2016-05-13ASoC: fsl_ssi: Fix samples being dropped at Playback startupArnaud Mouiche
If the capture is already running while playback is started, it is highly probable (>80% in a 8 channels scenario) that samples are lost between the DMA and TX fifo. The reason is that SIER.TDMAE is set before STCR.TFEN0, leaving a time window where the FIFO doesn't receive the samples written by the DMA. This particular case happened only if capture is already enabled as SCR.SSIEN is already set at the playback startup instant.

Manage the hda idisp link using shiny new link APIs. We need to keep link On while we probe and also hold the reference in runtime resume and drop in suspend Signed-off-by: Jeeja KP <jeeja.kp@intel.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2016-05-13ASoC: Intel: Skylake: add link managementVinod Koul
Use shiny new link APIs to manage the links. Also remove old link configuration logic from driver. We need to keep link and cmd dma to off during active suspend to allow system to enter low power state and turn it on if the link and cmd dma was on before active suspend in active resume.

2016-05-13ALSA: hdac: add link pm and ref countingVinod Koul
The HDA links can be switched off when not is use, similarly command DMA can be stopped as well. This calls for a reference counting mechanism on the link by it's users to manage the link power. The DMA can be turned off when all links are off For this we add two APIs snd_hdac_ext_bus_link_get snd_hdac_ext_bus_link_put They help users to turn up/down link and manage the DMA as well Signed-off-by: Jeeja KP <jeeja.kp@intel.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com> Acked-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Mark Brown <broonie@kernel.org>
