Subject: [PATCH v3 09/38] soc/tegra: pmc: Remove public pad voltage APIs
Date: Thu, 30 Aug 2018 18:06:10 +0300	[thread overview]
Message-ID: <20180830150639.21048-10-avienamo@nvidia.com> (raw)
In-Reply-To: <20180830150639.21048-1-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.
