2014-11-20ASoC: adau1701: Implement sigmadsp safeloadLars-Peter Clausen1-2/+55
The safeload feature allows to load up to 5 parameter memory registers atomically. This is helpful for switching between e.g. filter settings without causing any glitches. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@kernel.org>
2014-11-20ASoC: sigmadsp: Restructure in preparation for fw v2 supportLars-Peter Clausen1-5/+28
The v2 file format of the SigmaDSP takes a more declarative style compared to the imperative style of the v1 format. In addition some features that are supported with v2 require the driver to keep state around for the firmware. This requires a bit of restructuring of both the firmware loader itself and the drivers making use of the firmware loader. Instead of loading and executing the firmware in place when the DSP is configured the firmware is now loaded at driver probe time. This is required since the new firmware format will in addition to the firmware data itself contain meta information describing the firmware and its requirements and capabilities. Those will for example be used to restrict the supported samplerates advertised by the driver to userspace to the list of samplerates supported for the firmware. This only does the restructuring required by the v2 format, but does not yet add support for the new format itself.

2014-07-03ASoC: adau1701: fix adau1701_reg_read()Daniel Mack1-2/+4
Fix a long standing bug in the read register routing of adau1701. The bytes arrive in the buffer in big-endian, so the result has to be shifted before and-ing the bytes in the loop.

2014-01-08ASoC: adau1701: Fix ADAU1701_SEROCTL_WORD_LEN_16 constantLars-Peter Clausen1-1/+1
The driver defines ADAU1701_SEROCTL_WORD_LEN_16 as 0x10 while it should be b10, so 0x2. This patch fixes it. Reported-by: Magnus Reftel <magnus.reftel@lockless.no> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@linaro.org> Cc: stable@vger.kernel.org
2013-08-12ASoC: adau1701: Use gpio_set_value_cansleep()Mark Brown1-10/+10
The GPIO manipulation done by this driver is never in atomic context so we can use gpio_set_value_cansleep() and support GPIOs that can't be set from atomic context. Signed-off-by: Mark Brown <broonie@linaro.org> Acked-by: Lars-Peter Clausen <lars@metafoo.de>

2013-06-25ASoC: adau1701: allow configuration of PLL mode pinsDaniel Mack1-7/+98
The ADAU1701 has 2 hardware pins to configure the PLL mode in accordance to the MCLK-to-LRCLK ratio. These pins have to be stable before the chip is released from reset, and a full reset cycle, including a new firmware download is needed whenever they change. This patch adds GPIO properties to the DT bindings of the Codec, and implements makes the set_sysclk memorize the configured sysclk. Because the run-time parameters are unknown at probe time, the first firmware download is postponed to the first hw_params call, when the driver can determine the mclk/lrclk divider. Subsequent downloads are only issued when the divider configuration changes.

2013-06-12ASoC: codecs: adau1701: factor out firmware resetDaniel Mack1-13/+36
Some runtime-determined constraints might need to be satisfied prior to firmware loading, so the actual download and releasing the device from reset has to be postponed. Factor it out first, so we have everything at one place. This also changes the behaviour in a way that adau1701_i2c_probe() will assert the reset line, and wait for the codec probe to release it.

2011-11-29ASoC: Move SigmaDSP firmware loader to ASoCLars-Peter Clausen1-1/+1
It has been pointed out previously, that the firmware subsystem is not the right place for the SigmaDSP firmware loader. Furthermore the SigmaDSP is currently only used in audio products and we are aiming for better integration into the ASoC framework in the future, with support for ALSA controls for firmware parameters and support dynamic power management as well. So the natural choice for the SigmaDSP firmware loader is the ASoC subsystem.

2011-11-23ASoC: Constify snd_soc_dai_ops structsLars-Peter Clausen1-1/+1
Commit 1ee46ebd("ASoC: Make the DAI ops constant in the DAI structure") introduced the possibility to have constant DAI ops structures, yet this is barley used in both existing drivers and also new drivers being submitted, although none of them modifies its DAI ops structure. The later is not surprising since existing drivers are often used as templates for new drivers. So this patch just constifies all existing snd_soc_dai_ops structs to eliminate the issue altogether. The patch was generated with the following coccinelle semantic patch: // <smpl> @@ identifier ops; @@ -struct snd_soc_dai_ops ops = +const struct snd_soc_dai_ops ops = { ... }; // </smpl> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
