* ASoC: sgtl5000: Fix noise on shutdown/removeFrancesco Dolcini2022-07-071-0/+1
| | | | | | | | | | | | | | | | | | Put the SGTL5000 in a silent/safe state on shutdown/remove, this is required since the SGTL5000 produces a constant noise on its output after it is configured and its clock is removed. Without this change this is happening every time the module is unbound/removed or from reboot till the clock is enabled again. The issue was experienced on both a Toradex Colibri/Apalis iMX6, but can be easily reproduced everywhere just playing something on the codec and after that removing/unbinding the driver.

* ASoC: sgtl5000: Fix VAG power-on handlingSebastian Reichel2020-04-151-0/+1
| | | | | | | | | | | | | | | | | As mentioned slightly out of patch context in the code, there is no reset routine for the chip. On boards where the chip is supplied by a fixed regulator, it might not even be resetted during (e.g. watchdog) reboot and can be in any state. If the device is probed with VAG enabled, the driver's probe routine will generate a loud pop sound when ANA_POWER is being programmed. Avoid this by properly disabling just the VAG bit and waiting the required power down time.

| | | | | | | | | | | | SGTL5000_SMALL_POP is a bit mask, not a value. Usage of correct definition makes device probing code more clear.

* ASoC: sgtl5000: Disable internal PLL earlyEric Nelson2016-06-151-0/+1
| | | | | | | | | | | | To handle the soft reboot case, the internal PLL must be disabled in SGTL5000_CHIP_CLK_CTRL before clearing bits SGTL5000_VCOAMP_POWERUP and SGTL5000_PLL_POWERUP in register SGTL5000_CHIP_ANA_POWER.

* ASoC: sgtl5000: Initialize CHIP_ANA_POWER to power-on defaultsEric Nelson2016-06-151-0/+1
| | | | | | | | | | | | | | | | | | Initialize CHIP_ANA_POWER to match power on defaults, which disables ADC, DAC, and charge pumps. In the process, remove references to the following register/bitfields from the sgtl5000_set_power_regs routine: CHIP_ANA_POWER/LINREG_SIMPLE_POWERUP and CHIP_LINREG_CTRL/LINREG_VDD_MASK And remove CHIP_ANA_POWER and CHIP_LINREG_CTRL from the set of default registers so they don't get clobbered by sgtl5000_fill_defaults().

| | | | | | | | | | | | | Currently, below code actually does not update any bit because SGTL5000_SMALL_POP is 0. snd_soc_update_bits(codec, SGTL5000_CHIP_REF_CTRL, SGTL5000_SMALL_POP, 1); The SGTL5000_SMALL_POP should be BIT(0) rather than 0, fix it.

* ASoC: sgtl5000: Fix SMALL_POP bit definitionFabio Estevam2014-11-141-1/+1
| | | | | | | | | | | | | | | | | | On a mx28evk with a sgtl5000 codec we notice a loud 'click' sound to happen 5 seconds after the end of a playback. The SMALL_POP bit should fix this, but its definition is incorrect: according to the sgtl5000 manual it is bit 0 of CHIP_REF_CTRL register, not bit 1. Fix the definition accordingly and enable the bit as intended per the code comment. After applying this change, no loud 'click' sound is heard after playback Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Signed-off-by: Mark Brown <broonie@kernel.org> Cc: stable@vger.kernel.org
