Subject: [PATCH 5/6] regulator: max77686: Remove support for board files
Date: Tue, 04 Nov 2014 09:49:45 +0100 [thread overview]
Message-ID: <1415090986-30623-6-git-send-email-k.kozlowski@samsung.com> (raw)
In-Reply-To: <1415090986-30623-1-git-send-email-k.kozlowski@samsung.com>
The driver is used only on Exynos based boards with DTS support.
Simplify the driver and remove dead (unused) entries in platform_data
structure.
Convert the driver to DTS-only version. Parse all regulators at once,
not one-by-one. Remove dependency on data provided by max77686 MFD
driver. Use new DT style parsing method for regulators init data.
