2014-10-20ASoC: tegra: drop owner assignment from platform_driversWolfram Sang
A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
2014-03-19ASoC: tegra: Use flat regcacheDylan Reid
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.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC cleanups from Olof Johansson: "This is the branch where we usually queue up cleanup efforts, moving drivers out of the architecture directory, header file restructuring, etc. Sometimes they tangle with new development so it's hard to keep it strictly to cleanups. Some of the things included in this branch are: * Atmel SAMA5 conversion to common clock * Reset framework conversion for tegra platforms - Some of this depends on tegra clock driver reworks that are shared with Mike Turquette's clk tree. * Tegra DMA refactoring, which are shared branches with the DMA tree. * Removal of some header files on exynos to prepare for multiplatform" * tag 'cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (169 commits) ARM: mvebu: move Armada 370/XP specific definitions to armada-370-xp.h ARM: mvebu: remove prototypes of non-existing functions from common.h ARM: mvebu: move ARMADA_XP_MAX_CPUS to armada-370-xp.h serial: sh-sci: Rework baud rate calculation serial: sh-sci: Compute overrun_bit without using baud rate algo serial: sh-sci: Remove unused GPIO request code serial: sh-sci: Move overrun_bit and error_mask fields out of pdata serial: sh-sci: Support resources passed through platform resources serial: sh-sci: Don't check IRQ in verify port operation serial: sh-sci: Set the UPF_FIXED_PORT flag serial: sh-sci: Remove duplicate interrupt check in verify port op serial: sh-sci: Simplify baud rate calculation algorithms serial: sh-sci: Remove baud rate calculation algorithm 5 serial: sh-sci: Sort headers alphabetically ARM: EXYNOS: Kill exynos_pm_late_initcall() ARM: EXYNOS: Consolidate selection of PM_GENERIC_DOMAINS for Exynos4 ARM: at91: switch Calao QIL-A9260 board to DT clk: at91: fix pmc_clk_ids data type attriubte PM / devfreq: use inclusion <mach/map.h> instead of <plat/map-s5p.h> ARM: EXYNOS: remove <mach/regs-clock.h> for exynos ...
2013-12-11ASoC: tegra: convert to standard DMA DT bindingsStephen Warren
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.

2013-12-09ASoC: tegra: fix uninitialized variables in set_fmtStephen Warren
In tegra*_i2s_set_fmt(), in the (fmt == SND_SOC_DAIFMT_CBM_CFM) case, "val" is never assigned to, but left uninitialized. The other case does initialized it. Fix this by initializing val at the start of the function, and only ever ORing into it. Update the handling of "mask" so it works the same way for consistency. Update tegra20_spdif.c to use the same code-style for consistency, even though it doesn't happen to suffer from the same problem at present.

2012-06-08ASoC: tegra: use regmap more directlyStephen Warren
Stop open-coding the caching of the ctrl registers; instead, use regmap_update_bits() to update parts of the register from different places. The removal of the open-coded cache will allow controls to be created which touch registers, which will be necessary if any of these modules are converted to CODECs. Get rid of tegra*_read/write; just call regmap_read/write directly. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
