Subject: [PATCH 22/40] ab8500-bm: Add support for the new ab8540 platform
Date: Fri, 15 Feb 2013 12:44:52 +0000 [thread overview]
Message-ID: <1360932310-30065-23-git-send-email-lee.jones@linaro.org> (raw)
In-Reply-To: <1360932310-30065-1-git-send-email-lee.jones@linaro.org>
Provide AB8540 platform specific information required to run the
Battery Management subsystem on AB8540 based devices. For this to
happen we see the introduction of separate platform specific data
structures and a means in which to process them.

Subject: [PATCH 22/40] ab8500-bm: Add support for the new ab8540 platform
Date: Fri, 15 Feb 2013 12:44:52 +0000 [thread overview]
Message-ID: <1360932310-30065-23-git-send-email-lee.jones@linaro.org> (raw)
In-Reply-To: <1360932310-30065-1-git-send-email-lee.jones@linaro.org>
Provide AB8540 platform specific information required to run the
Battery Management subsystem on AB8540 based devices. For this to
happen we see the introduction of separate platform specific data
structures and a means in which to process them.
