From 0aa5e47d1f3b395c4d2540a28ee37694466ee19b Mon Sep 17 00:00:00 2001 From: Russell King Date: Tue, 20 Nov 2012 12:20:14 +0000 Subject: [PATCH] ASoC: kirkwood-dma: remove restriction on sample rates This is part of a patch found in Rabeeh Khoury's git tree for the cubox. The kirkwood DMA hardware for ASoC does not impose any restrictions on the sample rates available, so it's silly to impose an artificial set in the DMA code. The restrictions come from the availble clocks to the I2S module, which are already handled in the I2S part of the driver.
