ASoC: da7213: add default clock handling

2020-07-07T12:03:22Z

This adds default clock/PLL configuration to the driver for usage with generic drivers like simple-card for usage with a fixed rate clock.

ASoC: da7213: Add regulator support

2020-05-18T13:34:53Z

This adds support for most regulators of da7212 for improved power management. The only thing skipped was the speaker supply, which has some undocumented dependencies. It's supposed to be either always-enabled or always-disabled.

ASoC: da7213: fix DAI_CLK_EN register bit overwrite

2019-05-02T01:57:47Z

If the da7213 codec is configured as Master with the DAPM power down delay time set, 'snd_soc_component_write' function overwrites the DAI_CLK_EN bit of DAI_CLK_MODE register which leads to audio play only once until it re-initialize after codec power up.

ASoC: da7213: add support for DSP modes

2017-11-09T11:42:26Z

DSP modes are documented in the data sheet but not enabled in the driver. The work-around already implemented for DA7218/9 is also required to make sure the bit clock handling in DSP modes follows ASoC conventions.

ASoC: da7213: Refactor sysclk(), pll() functions to improve handling

2016-08-08T10:54:40Z

Currently the handling of the PLL in the driver is a little clunky, and not ideal for all modes. This patch updates the code to make it cleaner and more sensible for the various PLL states. Key items of note are: - MCLK squaring is now handled directly as part of the sysclk() function, removing the need for a private flag to set this feature. - All PLL modes are defined as an enum, and are handled as a case statement in pll() function to clean up configuration. This also removes any need for a private flag for SRM. - For 32KHz mode, checks are made on codec master mode and correct MCLK rates, to avoid incorrect usage of PLL for this operation. - For 32KHz mode, SRM flag now correctly enabled and fout set to sensible value to achieve appropriate PLL dividers.

ASoC: da7213: Update PLL ranges to improve locking at frequency boundary

2016-05-10T18:24:19Z

This update changes the dividers used for ranges of input MCLK frequencies, to improve PLL locking for a corner case when at edge of MCLK frequency input divider range. Signed-off-by: Adam Thomson Signed-off-by: Mark Brown

ASoC: da7213: Default PC counter to free-running when DAI disabled

2016-05-10T18:24:19Z

Currently PC counter is always synchronised to DAI which means that when the DAI is disabled, features such as ALC calibration cannot be executed successfully. This patch makes sure that when the DAI is disabled, PC counter is set to free-running. Signed-off-by: Adam Thomson Signed-off-by: Mark Brown

ASoC: da7213: Add checking of SRM lock status before enabling DAI

2016-05-10T18:24:19Z

When the codec is DAI clk slave, and the SRM feature of the PLL is being used, the enabling of the DAI should occur only after the PLL has locked to the incoming WCLK. This update adds checking to the the DAI widget event, so it waits for SRM to lock. There is also a timeout if that lock doesn't occur within a given time.

ASoC: da7213: Add DAI DAPM event to control DAI clocks

2016-05-10T18:24:16Z

Currently, when Codec is I2S master DAI clocks are continuously generated even if all audio streams have stopped. To improve efficiency, control of the DAI clocks for master mode have been moved to a DAPM widget event so they're only enabled as required. Signed-off-by: Adam Thomson Signed-off-by: Mark Brown
