git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull driver core update from Greg KH: "Here's the set of driver core patches for 3.19-rc1. They are dominated by the removal of the .owner field in platform drivers. They touch a lot of files, but they are "simple" changes, just removing a line in a structure. Other than that, a few minor driver core and debugfs changes. There are some ath9k patches coming in through this tree that have been acked by the wireless maintainers as they relied on the debugfs changes.

2014-11-18ASoC: Rename snd_soc_dai_driver struct ac97_control field to bus_controlLars-Peter Clausen1-1/+1
Setting the ac97_control field on a CPU DAI tells the ASoC core that this DAI in addition to audio data also transports control data to the CODEC. This causes the core to suspend the DAI after the CODEC and resume it before the CODEC so communication to the CODEC is still possible. This is not necessarily something that is specific to AC'97 and can be used by other buses with the same requirement. This patch renames the flag from ac97_control to bus_control to make this explicit. While we are at it also change the type from int to bool. The following semantich patch was used for automatic conversion of the drivers: // <smpl> @@ identifier drv; @@ struct snd_soc_dai_driver drv = { - .ac97_control + .bus_control = - 1 + true }; // </smpl> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@kernel.org>

2014-03-25ASoC: tegra: move AC97 clock handling to the machine driverLucas Stach1-14/+1
On Tegra the convention is to have a single machine driver that's controlling the whole audio subsystem. Move the clock handling to the machine driver, to be in line with the other Tegra drivers and give the machine driver full control over the single Tegra audio PLL.

2014-03-19ASoC: tegra: Use flat regcacheDylan Reid1-1/+1
When using an rbtree cache, there can be allocations the first time a register is accessed. This can cause an attempt to schedule while atomic in the case that the regmap is using a spinlock. This could be fixed by either initializing all the registers or using a flat cache. The register maps for tegra30_ahub and tegra30_i2s are dense and don't save much from using a tree so convert them to flat. Tegra30 changes tested on Norrin, Tegra20 changes compile.

2013-12-11ASoC: tegra: convert to standard DMA DT bindingsStephen Warren1-11/+0
By passing no flags when calling snd_dmaengine_pcm_register() from tegra_pcm.c, we end up using dma_request_slave_channel() rather than dmaengine_pcm_compat_request_channel(), and hence rely on the standard DMA DT bindings and stashing the DMA slave ID away during channel allocation. This means there's no need to use a custom DT property to store the slave ID. So, remove all the code that parsed it.

2013-06-27ASoC: ac97: Support multi-platform AC'97Mark Brown1-2/+10
Currently we can only have a single platform built in with AC'97 support due to the use of a global variable to provide the bus operations. Fix this by making that variable a pointer and having the bus drivers set the operations prior to registering. This is not a particularly good or nice approach but it avoids blocking multiplatform and a real fix involves fixing the fairly deep problems with AC'97 support - we should be converting it to a real bus.
