2020-11-30gpio: omap: handle deferred probe with dev_err_probe() for gpiochip_add_data()Grygorii Strashko
The gpiochip_add_data() may return -EPROBE_DEFER which is not handled properly by TI GPIO driver and causes unnecessary boot log messages. Hence, add proper deferred probe handling with new dev_err_probe() API.

2020-11-30gpio: xra1403: remove unneeded spi_set_drvdata()Alexandru Ardelean
There is no matching spi_get_drvdata() call in the driver, so there is no need to do spi_set_drvdata(). This looks like it probably was copied from a driver that used both spi_set_drvdata() & spi_get_drvdata().

2020-11-30gpio: dwapb: Remove unnecessary error messageDamien Le Moal
In dwapb_get_reset(), if devm_reset_control_get_optional_shared() fails, an error message is printed even if the failure is the benign EPROBE_DEFER error due to the reset controller not yet being initialized. Use dev_err_probe() to handle devm_reset_control_get_optional_shared() errors to avoid unnecessarilly printing an error message for the deferred probe error.

2020-11-25gpio: exar: switch to a simpler IDA interfaceBartosz Golaszewski
We don't need to specify any ranges when allocating IDs so we can switch to ida_alloc() and ida_free() instead of the ida_simple_ counterparts. ida_simple_get(ida, 0, 0, gfp) is equivalent to ida_alloc_range(ida, 0, UINT_MAX, gfp) which is equivalent to ida_alloc(ida, gfp).

2020-11-16gpiolib: acpi: Set initial value for output pin based on bias and polarityVasile-Laurentiu Stanimir
GpioIo() resources don't contain an initial value for the output pin. Therefore instead of deducting its value solely based on bias field we should deduce that value from the polarity and the bias fields. Typical scenario is, when pin is defined in the table and its polarity, specified in _DSD or via platform code, is defined as active low, in the following call chain: -> acpi_populate_gpio_lookup() -> acpi_gpio_to_gpiod_flags() it will return GPIOD_OUT_HIGH if bias is set no matter if polarity is GPIO_ACTIVE_LOW, so it will return the current level instead of the logical level.
