Subject: [PATCH v2 6/7] soc/tegra: pmc: Remove public pad voltage APIs
Date: Wed, 11 Jul 2018 17:05:38 +0300 [thread overview]
Message-ID: <1531317938-4099-1-git-send-email-avienamo@nvidia.com> (raw)
In-Reply-To: <1531317693-3520-1-git-send-email-avienamo@nvidia.com>
Make tegra_io_pad_set_voltage() and tegra_io_pad_get_voltage() static
and remove the prototypes from pmc.h. Remove enum tegra_io_pad_voltage
and use the defines from <dt-bindings/pinctrl/pinctrl-tegra-io-pad.h>
instead.
These functions aren't used outside of the pmc driver and new use cases
should use the pinctrl interface instead.
