Subject: [PATCH] regulator: max8649 - fix setting extclk_freq
Date: Fri, 01 Oct 2010 13:56:27 +0800 [thread overview]
Message-ID: <1285912587.12422.2.camel@mola> (raw)
The SYNC bits are BIT6 and BIT7 of MAX8649_SYNC register.
pdata->extclk_freq could be [0|1|2].
(MAX8649_EXTCLK_26MHZ|MAX8649_EXTCLK_13MHZ|MAX8649_EXTCLK_19MHZ)
It requires to left shift 6 bits to properly set extclk_freq.
