  • a7dc662c6   ASoC: codecs: PCM1789: unconditionally flush work ... Browse Code »

    Work is guaranteed to be initialized on exit. Drop the unnecessary
    if statement and always call flush_work.

    This fixes a warning seen with clang:
    sound/soc/codecs/pcm1789.c:265:13: warning: address of 'priv->work' will
    always evaluate to 'true' [-Wpointer-bool-conversion]
    if (&priv->work)
    ~~ ~~~~~~^~~~

    When CONFIG_GPIOLIB is disabled, this codec fails to build
    because gpio/consumer.h is not included implicitly.

    sound/soc/codecs/pcm1789.c: In function 'pcm1789_common_init':
    sound/soc/codecs/pcm1789.c:247:19: error: implicit declaration of function 'devm_gpiod_get_optional'; did you mean 'devm_gpio_request_one'? [-Werror=implicit-function-declaration]
    pcm1789->reset = devm_gpiod_get_optional(dev, "reset", GPIOD_OUT_HIGH);
    ^~~~~~~~~~~~~~~~~~~~~~~

    Add Texas Instruments's PCM1789 DAC support.
    It is a simple DAC and does not have many registers.

    One particularity about this DAC is that the clocks must be
    always enabled. Also, an entire software reset is necessary
    while starting to play a sound otherwise, the clocks are not
    synchronized (so the DAC is not able to send data).
