| |
Hi,
currently it is not possible to have a gpio enabled regulator that uses gpio 0. 0 is a valid gpio identifier so it has to be supported.
This series tries to fix this issue by adding a regulator_config field 'ena_gpio_valid' which should be true if ena_gpio is a valid gpio identifier. Otherwise ena_gpio is ignored.
Patch 1 introduces 'ena_gpio_valid'. Patch 2 updates all drivers that set ena_gpio. Patch 3 changes the regulator core check for ena_gpio.
Patch 4 and 5 are minor changes to regulator drivers unrelated to the gpio-0 issue.
Best regards,
Markus
