From 83fe518a839e317480e50a138ef4acd73510d7ce Mon Sep 17 00:00:00 2001 From: George Shore Date: Thu, 21 Jan 2010 11:40:48 +0000 Subject: spi/dw_spi: enable platform specific chipselect. The driver core allows for a platform-specific chipselect assert/deassert function, however the chipselect function in the core doesn't take advantage of this fact. This enables the use of a custom function, should it be defined.
