Subject: [PATCH 4/5] pxa/mioa701: add V3 gain configuration for Maxim 1586 voltage regulator
Date: Thu, 28 May 2009 07:15:17 +0200 [thread overview]
Message-ID: <1243487718-5423-3-git-send-email-philipp.zabel@gmail.com> (raw)
In-Reply-To: <878wkibmv9.fsf@free.fr>
Maxim 1586 V3 gain can be configured by external resistors
(R24, R25) connected to the FB3 pin. To avoid accidental
overvoltage, it now requires this gain to be configured
explicitly.
