  • 81f2a5b4a   leds: lp55xx: configure the clock detection ... Browse Code »

    Now LP55xx provides automatic clock detection API, lp55xx_is_extclk_used().
    The clock configuration can be done by the driver itself.

    (a) Concept
    The default value is set by each driver with clock selection.
    The internal clock selection bit is updated in case that the external clock
    is not detected or clock rate is not 32KHz.

    (b) Change on LP55xx platform data
    The clock configuration is done automatically, so no need to define
    'update_config' in the platform side.
    Correlated information are removed in the documentations and header.

    (c) Definitions moved from header to driver files
    CONFIG register values are moved each driver, LP5521 and LP5562.
    Not necessary definitions are removed also.

  • 011af7bc7   drivers/leds/leds-lp5521.c: support led pattern data ... Browse Code »

    The lp5521 has autonomous operation mode without external control.
    Using lp5521_platform_data, various led patterns can be configurable.
    For supporting this feature, new functions and device attribute are
    added.

    Structure of lp5521_led_pattern: 3 channels are supported - red, green
    and blue. Pattern(s) of each channel and numbers of pattern(s) are
    defined in the pla= tform data. Pattern data are hexa codes which
    include pattern commands such like set pwm, wait, ramp up/down, branch
    and so on.

    Pattern mode functions:
    * lp5521_clear_program_memory
    Before running new led pattern, program memory should be cleared.
    * lp5521_write_program_memory
    Pattern data updated in the program memory via the i2c.
    * lp5521_get_pattern
    Get pattern from predefined in the platform data.
    * lp5521_run_led_pattern
    Stop current pattern or run new pattern.
    Transition time is required between different operation mode.

    Device attribute - 'led_pattern': To load specific led pattern, new device
    attribute is added.

    When the lp5521 driver is unloaded, stop current led pattern mode.

    Documentation updated : description about how to define the led patterns
    and example.

  • 3b49aacd0   drivers/leds/leds-lp5521.c: add 'update_config' in the lp5521_platform_data ... Browse Code »

    The value of CONFIG register(Addr 08h) is configurable. For supporting
    this feature, update_config is added in the platform data. If
    'update_config' is not defined, the default value is 'LP5521_PWRSAVE_EN |
    LP5521_CP_MODE_AUTO | LP5521_R_TO_BATT'.

    To define CONFIG register in the platform data, the bit definitions were
    mo= ved to the header file.

    Documentation updated : description about 'update_config' and example.

  • 5ae4e8a77   drivers/leds/leds-lp5521.c: add 'name' in the lp5521_led_config ... Browse Code »

    The name of each led channel can be configurable. For the compatibility,
    the name is set to default value(xx:channelN) when 'name' is not defined.
