2017-07-17ASoC: fsl_esai: constify snd_soc_dai_ops structureGustavo A. R. Silva1-1/+1
This structure is only stored in the ops field of a snd_soc_dai_driver structure. That field is declared const, so snd_soc_dai_ops structures that have this property can be declared as const also.

2016-09-20ASoC: fsl_esai: use flat regmap cacheMarek Vasut1-1/+1
Same as commit ce492b3b8f99cf9d2f807ec22d8805c996a09503 Subject: drm/fsl-dcu: use flat regmap cache Using flat regmap cache instead of RB-tree to avoid the following lockdep warning on driver load: WARNING: CPU: 0 PID: 1 at kernel/locking/lockdep.c:2871 lockdep_trace_alloc+0x104/0x128 DEBUG_LOCKS_WARN_ON(irqs_disabled_flags(flags)) The RB-tree regmap cache needs to allocate new space on first writes. However, allocations in an atomic context (e.g. when a spinlock is held) are not allowed. The function regmap_write calls map->lock, which acquires a spinlock in the fast_io case. Since the driver uses MMIO, the regmap bus of type regmap_mmio is being used which has fast_io set to true.

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "There are little changes in core part, but lots of development are found in drivers, especially ASoC. The diffstat shows regmap-related changes for a slight API additions / changes, and that's all. Looking at the code size statistics, the most significant addition is for Intel Skylake. (Note that SKL support is still underway, the codec driver is missing.) Also STI controller driver is a major addition as well as a few new codec drivers. In HD-audio side, there are fewer changes than the past. The noticeable change is the support of ELD notification from i915 graphics driver. Thus this pull request carries a few changes in drm/i915. Other than that, USB-audio got a rewrite of runtime PM code. It was initiated by lockdep warning, but resulted in a good cleanup in the end. Below are the highlights: Common: - Factoring out of AC'97 reset code from ASoC into the core helper - A few regmap API extensions (in case it's not pulled yet) ASoC: - New drivers for Cirrus CS4349, GTM601, InvenSense ICS43432, Realtek RT298 and ST STI controllers - Machine drivers for Rockchip systems with MAX98090 and RT5645 and RT5650 - Initial driver support for Intel Skylake devices - Lots of rsnd cleanup and enhancements - A few DAPM fixes and cleanups - A large number of cleanups in various drivers (conversion and standardized to regmap, component) mostly by Lars-Peter and Axel HD-audio: - Extended HD-audio core for Intel Skylake controller support - Quirks for Dell headsets, Alienware 15 - Clean up of pin-based quirk tables for Realtek codecs - ELD notifier implenetation for Intel HDMI/DP USB-audio: - Refactor runtime PM code to make lockdep happier" * tag 'sound-4.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (411 commits) drm/i915: Add locks around audio component bind/unbind drm/i915: Drop port_mst_index parameter from pin/eld callback ALSA: hda - Fix missing inline for dummy snd_hdac_set_codec_wakeup() ALSA: hda - Wake the codec up on pin/ELD notify events ALSA: hda - allow codecs to access the i915 pin/ELD callback drm/i915: Call audio pin/ELD notify function drm/i915: Add audio pin sense / ELD callback ASoC: zx296702-i2s: Fix resource leak when unload module ASoC: sti_uniperif: Ensure component is unregistered when unload module ASoC: au1x: psc-i2s: Convert to use devm_ioremap_resource ASoC: sh: dma-sh7760: Convert to devm_snd_soc_register_platform ASoC: spear_pcm: Use devm_snd_dmaengine_pcm_register to fix resource leak ALSA: fireworks/bebob/dice/oxfw: fix substreams counting at vmalloc failure ASoC: Clean up docbook warnings ASoC: txx9: Convert to devm_snd_soc_register_platform ASoC: pxa: Convert to devm_snd_soc_register_platform ASoC: nuc900: Convert to devm_snd_soc_register_platform ASoC: blackfin: Convert to devm_snd_soc_register_platform ASoC: au1x: Convert to devm_snd_soc_register_platform ASoC: qcom: Constify asoc_qcom_lpass_cpu_dai_ops ...

2014-11-25ASoC: fsl_esai: Use dynamic slot width as defaultNicolin Chen1-5/+7
The driver previously used 32-bit fixed slot width as default. In result, ESAI might use 32-bit length to capture 16-bit width audio slot from CODEC side when ESAI is running as DAI slave. So this patch just removes the default slot_width so as to use dynamic slot width. If there comes a specific situation that needs a fixed width, the machine driver shall set slot_width via set_tdm_slot() so as to let the ESAI driver replace the dynamic width policy with the fixed value.

Original driver didn't store the number of slots, just fix the slot number to 2, use this default number to calculate bclk and pins for TX/RX.

This reverts commit a603c8ee526f5ea9ad9b40710308766299ad8a69. fsl_asoc_xlate_tdm_slot_mask() is different with snd_soc_xlate_tdm_slot_mask(). fsl_asoc_xlate_tdm_slot_mask() will set the enabled bit to 0, disabled bit to 1. snd_soc_xlate_tdm_slot_mask() will set the enabled bit to 1, disabled bit to 0. For esai when the bit value is 1, the slot is enabled, when the bit value is 0, the slot is disabled. If using fsl_asoc_xlate_tdm_slot_mask(), the esai will work abnormally. So revert this patch, make the esai use default function.

2014-01-10ASoC: fsl_esai: Add ESAI CPU DAI driverNicolin Chen1-0/+815
This patch implements a device-tree-only CPU DAI driver for Freescale ESAI controller that supports: - 12 channels playback and 8 channels record. [ Some of the inner transmitters and receivers are sharing same group of pins. So the maxmium 12 output or 8 input channels are only valid if there is no pin conflict occurring to it. ] - Independent (asynchronous mode) or shared (synchronous mode) transmit and receive sections with separate or shared internal/external clocks and frame syncs, operating in Master or Slave mode. [ Current ALSA seems not to allow CPU DAI drivers to configure DAI format separately for PLAYBACK and CAPTURE. So this first version only supports the case that uses the same DAI format for both directions. ] - Various DAI formats: I2S, Left-Justified, Right-Justified, DSP-A and DSP-B. - Programmable word length (8, 16, 20 or 24bits) - Flexible selection between system clock or external oscillator as input clock source, programmable internal clock divider and frame sync generation.
