2020-09-23ASoC: tas2770: Remove unused variablesDan Murphy1-6/+2
Remove unused variables in the private struct and the code as these variables are initially set and then there is no additional code utilizing these variables. Signed-off-by: Dan Murphy <dmurphy@ti.com> Link: https://lore.kernel.org/r/20200923132600.10652-6-dmurphy@ti.com Signed-off-by: Mark Brown <broonie@kernel.org>
2020-09-23ASoC: tas2770: Remove ti,asi-format codeDan Murphy1-1/+0
Remove the code to support the asi-format binding property. The code does nothing except read the property and set a variable. No additional action is taken except to reset the variable. The property is supposed to set the rising or falling RX edge detection of the SBCLK but this edge detection is done by checking the DAI_FMT_INV_MASK.

2020-09-23ASoC: tas2770: Add shutdown capability via a GPIODan Murphy1-0/+1
Add the hardware shutdown mechanism to shutdown and wake up the device via a GPIO. Signed-off-by: Dan Murphy <dmurphy@ti.com> Link: https://lore.kernel.org/r/20200923132600.10652-2-dmurphy@ti.com Signed-off-by: Mark Brown <broonie@kernel.org>
2020-09-21ASoC: tas2770: Convert bit mask to GENMASK in headerDan Murphy1-18/+19
Update the hardcoded masks with the GENMASK macro. Also update some of the hardcoded bits with the BIT macro Signed-off-by: Dan Murphy <dmurphy@ti.com> Link: https://lore.kernel.org/r/20200918190548.12598-6-dmurphy@ti.com Signed-off-by: Mark Brown <broonie@kernel.org>
2020-07-22ASoC: Replace HTTP links with HTTPS onesAlexander A. Klimov1-1/+1
Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

2019-10-07ASoc: tas2770: Remove unused defines and variablesDan Murphy1-21/+0
Remove unused defines and structure variables that are not referenced by the code. If these are needed for future enhancements then they should be added at that time.
