Subject: [PATCH v4 1/7] regulator: core: Move of_find_regulator_by_node() to of_regulator.c
Date: Mon, 22 Jan 2018 15:30:06 +0100	[thread overview]
Message-ID: <1516631412-17542-2-git-send-email-m.purski@samsung.com> (raw)
In-Reply-To: <1516631412-17542-1-git-send-email-m.purski@samsung.com>

As of_find_regulator_by_node() is an of function it should be moved from
core.c to of_regulator.c. It provides better separation of device tree
functions from the core and allows other of_functions in of_regulator.c
to resolve device_node to regulator_dev. This will be useful for
implementation of parsing coupled regulators properties.

Declare of_find_regulator_by_node() function in internal.h as well as
regulator_class and dev_to_rdev(), as they are needed by
of_find_regulator_by_node().
