  • 4b90432dc   leds: leds-ns2: handle can_sleep GPIOs ... Browse Code »

    On the board n090401 (Seagate NAS 4-Bay), some of the LEDs are handled
    by the leds-ns2 driver. This LEDs are connected to an I2C GPIO expander
    (PCA95554PW) which means that GPIO access may sleep. This patch makes
    leds-ns2 compatible with such GPIOs by using the *_cansleep() variant of
    the GPIO functions. As a drawback this functions can't be used safely in
    a timer context (with the timer LED trigger for example). To fix this
    issue, a workqueue mechanism (copied from the leds-gpio driver) is used.

    Note that this patch also updates slightly the ns2_led_sata_store
    function. The LED state is now retrieved from cached values instead of
    reading the GPIOs previously. This prevents ns2_led_sata_store from
    working with a stale LED state (which may happen when a delayed work
    is pending).

  • f7fafd083   leds: leds-ns2: move LED modes mapping outside of the driver ... Browse Code »

    On the board n090401 (Seagate NAS 4-Bay), the LED mode mapping (GPIO
    values to LED mode) is different from the one used on other boards
    supported by the leds-ns2 driver.

    With this patch the hardcoded mapping is removed from leds-ns2. Now,
    it must be defined either in the platform data (if an old-fashion board
    setup file is used) or in the DT node. In order to allow the later, this
    patch also introduces a modes-map property for the leds-ns2 DT binding.

  • a036e4cde   leds: leds-ns2: remove unnecessary platform_set_drvdata() ... Browse Code »

    The driver core clears the driver data to NULL after device_release
    or on probe failure, since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d
    (device-core: Ensure drvdata = NULL when no driver is bound).
    Thus, it is not needed to manually clear the device driver data to NULL.

  • 3de1929ba   leds: leds-ns2: fix oops at module removal ... Browse Code »

    This patch fixes a regression introduced by commit 72052fcc10
    ("leds: leds-ns2: add device tree binding").

    When the driver is initialized with device tree data, platform_data
    pointer is NULL. This causes a kernel oops at removal.

    To fix this bug, num_leds is moved into driver_data and platform_data
    is not longer used from ns2_led_remove().

  • 9d04cbaad   leds: leds-ns2: set devm_gpio_request_one() flags param correctly ... Browse Code »

    The devm_gpio_request_one() flags parameter was set to:

    GPIOF_DIR_OUT | gpio_get_value(template->cmd)

    GPIOF_DIR_OUT and GPIOF_DIR_IN are defined as below:

    GPIOF_DIR_OUT (0 << 0)
    GPIOF_DIR_IN (1 << 0)

    So, when 'gpio_get_value(template->cmd)' is 1, the gpio pin can
    be set as input, instead of output.

    To prevent this problem, GPIOF_OUT_INIT flags should be used when
    using devm_gpio_request_one().

    Same goes for 'gpio_get_value(template->slow)' case.

  • e5971bbc1   leds: leds-ns2: fix private driver data storage ... Browse Code »

    dev_set_drvdata() can't be used to set the driver private data pointer.
    This would overwrite the led classdev object previously registered by
    led_classdev_register().

    Note that despite this mistake, the driver work fine because led_dat and
    led_dat->cdev are at the same memory address.

    This patch add a LED class driver for the dual-GPIO LEDs found on the

    Network Space (Max) v2 and d2 Network v2 boards.

    This dual-GPIO LED is wired to a CPLD and can blink in relation with the
    SATA activity. The driver expose this capability through a "sata" sysfs
    attribute.
