[PATCH 5/8] dmaengine: ste_dma40: Ensure src and dst registers are configured correctly

From: Lee Jones
Date: Tue Apr 09 2013 - 14:40:51 EST


Confusingly d40_log_cfg() is used to set up the logical channel
configuration registers, but d40_phy_cfg() is used to configure
physical _and_ logical registers, so it should be called in both
cases. It is the function call's final attribute which determines
whether it's a physical or logical channel, not whether the
function is called or not.
