Subject: [PATCH 0/5] regulator: Fix core behaviour for gpio 0
Date: Mon, 6 Oct 2014 22:17:10 +0200 [thread overview]
Message-ID: <1412626635-7404-1-git-send-email-mpa@pengutronix.de> (raw)
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

regulator: Add ena_gpio_valid config
regulator: Set ena_gpio_valid in regulator drivers
regulator: Fix ena_gpio check
regulator: Use gpio_is_valid
regulator: Remove unnecessary ena_gpio initializations
