Subject: [PATCH v3 1/9] regmap: Introduce regmap_get_max_register.
Date: Tue, 24 Mar 2015 22:29:39 +0000 [thread overview]
Message-ID: <1427236179-18580-1-git-send-email-srinivas.kandagatla@linaro.org> (raw)
In-Reply-To: <1427236116-18531-1-git-send-email-srinivas.kandagatla@linaro.org>
This patch introduces regmap_get_max_register() function which would be
used by the infrastructures like eeprom framework built on top of
regmap.
