2013-10-30ASoC: rt5640: Fix ignored error checksTakashi Iwai
The negative error value returned from get_sdp_info() is ignored because it's assigned to unsigned variables. Spotted by coverity CIDs 1042657, 1042658. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Mark Brown <broonie@linaro.org>
2013-10-19ASoC: rt5640: Don't go to standby on resumeMark Brown
There is no need for the CODEC to go to standby on resume since the core will power it up as needed and in any case it is an idle_bias_off CODEC so would normally sit with bias off while idle. Signed-off-by: Mark Brown <broonie@linaro.org> Tested-by: Stephen Warren <swarren@nvidia.com>
2013-10-19ASoC: rt5640: Power down LDO while suspendedMark Brown
If we have control over the LDO then disable it during suspend; the device is already being put into reset so will be non-functional over suspend anyway and this will save a small amount of power. Signed-off-by: Mark Brown <broonie@linaro.org> Tested-by: Stephen Warren <swarren@nvidia.com>
2013-09-19ASoC: rt5640: Omit ACPI match table only if !ACPIThierry Reding
The ACPI_PTR() macro evaluates to NULL if ACPI is disabled and hence the ACPI match table won't be used, causing the compiler to complain. Avoid this by protecting the table using an #ifdef CONFIG_ACPI. Signed-off-by: Thierry Reding <treding@nvidia.com> Signed-off-by: Mark Brown <broonie@linaro.org>

2013-06-12ASoC: rt5640: add device tree supportStephen Warren
Modify the RT5640 driver to parse platform data from device tree. Write a DT binding document to describe those properties. Slight re-ordering of rt5640_i2c_probe() to better fit the DT parsing. Since ldo1_en is optional, guard usage of it with gpio_is_valid(), rather than open-coding an if (gpio) check.
