Subject: [PATCH] ASoC: Fix wrong define for AD1836_ADC_WORD_OFFSET
Date: Tue, 22 Nov 2011 09:46:51 +0800 [thread overview]
Message-ID: <1321926411.4764.1.camel@phoenix> (raw)
According to the datasheet:
The BIT[5:4] of ADC Control Register 2 is to control the word width.
00 = 25 Bits
01 = 20 Bits
10 = 16 Bits
11 = Invalid
Thus, the AD1836_ADC_WORD_OFFSET should be defined as 4.
