Subject: [PATCH] ASoc: sam9g20_wm8731: use the proper SYSCKL value
Date: Tue, 24 May 2011 11:51:16 +0200	[thread overview]
Message-ID: <1306230676-28688-1-git-send-email-nicolas.ferre@atmel.com> (raw)

at91sam9g20 is providing master clock to wm8731: not using a crystal but an
external MCLK. We can avoid conflict and save power using WM8731_SYSCLK_MCLK as
we do not need oscillator to be powered.
