Subject: [PATCH v2 0/4] regulator: Fix core behaviour for gpio 0

Hi,

In v2 of this series I renamed the added regulator_config field
'ena_gpio_valid' to 'ena_gpio_initialized'. We have a gpio_is_valid check in
the regulator core code, so no need to require a valid ena_gpio. It should
avoid a lot of gpio_is_valid checks in regulator drivers.

v2 is also backward compatible now, so if ena_gpio_initialized is false, it
will still handle gpios > 0. There are some more changes on the regulator
driver patches, which now do not set ena_gpio_initialized for pdata code.

This series fixes the handling of gpio 0 in the regulator framework.

Best regards,

Markus

  regulator: Add ena_gpio_initialized to regulator_config
  regulator: Set ena_gpio_initialized in regulator drivers
  regulator: fixed: Use gpio_is_valid
  regulator: gpio: Use gpio_is_valid
