ASoC: cs35l3x: Use neutral language in amp drivers

2021-05-26T11:07:16Z

Revise variable names and comments in cs35l35 and cs35l36 amp drivers. Signed-off-by: David Rhodes Reviewed-by: Pierre-Louis Bossart Message-Id: <20210525194439.2232908-1-drhodes@opensource.cirrus.com> Signed-off-by: Mark Brown

ASoC: cs35l35: Correct errata handling

2021-05-10T16:27:51Z

Currently the check of errata_chk will always evaluate to false since the values tested don't come under the mask used. A shift of the field is missing, add this. Also there is an error in the values tested, they don't match the comment and the value 0x3 is not a valid value for the field in question. Update the value to match the comment.

ASoC: cs35l35: Allow user to configure IMON SCALE

2017-04-21T17:01:38Z

On the chip the IMON signal is a full 24-bits however normally only some of the bits will be sent over the bus. The chip provides a field to select which bits of the IMON will be sent back, this is the only feedback signal that has this feature. Add an additional entry to the cirrus,imon device tree property to allow the IMON scale parameter to be passed.

ASoC: cs35l35: Improve power down time

2017-04-06T18:27:52Z

Shorten the time it takes to power down the amp by disabling the volume ramp whilst doing the final shutdown. The driver has already muted the amplifier at this stage so doing the volume ramp serves no purpose. Signed-off-by: Charles Keepax Acked-by: Brian Austin Signed-off-by: Mark Brown

ASoC: cs35l35: Stash dev pointer directly rather than CODEC pointer

2017-03-17T21:40:31Z

The driver stashes a CODEC pointer in the cs35l35_private structure, which is used to obtain a struct device pointer for error messages in the interrupt handler. However, doing so is not very safe as the interrupt is registered, as it should be in bus probe, but the CODEC pointer can't be safely stored until the ASoC level probe. This leaves a window between the two probes where if any interrupts are received a NULL pointer will be deferenced in the IRQ handler. Fix this issue by saving a pointer to the device directly and passing that to the error messages in the interrupt handler rather than using the CODEC pointer to access the device pointer.

ASoC: cs35l35: Add for configuring drive mode in unused slots

2017-03-13T16:09:17Z

Add support for setting how the I2S pins are driven in unused slots, currently the chip will just use the default of drive 0, however this causes issues when multiple devices are attached to the same bus. Signed-off-by: Charles Keepax Acked-by: Brian Austin Signed-off-by: Mark Brown
