Subject: [PATCH v4 02/14] regulator: Add function to map modes to struct regulator_desc
Date: Mon, 3 Nov 2014 15:40:37 +0100 [thread overview]
Message-ID: <1415025649-8119-3-git-send-email-javier.martinez@collabora.co.uk> (raw)
In-Reply-To: <1415025649-8119-1-git-send-email-javier.martinez@collabora.co.uk>
The regulator-initial-mode and regulator-mode DT properties allows to
configure the regulator operating modes at startup or when a system
enters into a susend state.
But these properties use as valid values the operating modes supported
by each device while the core deals with the standard operating modes.
So a mapping function is needed to translate from the hardware specific
modes to the standard ones.
This mapping is a non-varying configuration for each regulator, so add
a function pointer to struct regulator_desc that will allow drivers to
define their callback to do the modes translation.
