From d7cbcc762ea88ad20e9005a85bf7d55939b5e9d2 Mon Sep 17 00:00:00 2001 From: Markus Niebel Date: Mon, 17 Feb 2014 17:33:16 +0100 Subject: spi: spi-mxc: add defines for clk inactive state for ECSPI Provide define for the SCLK_CTL field of the config reg of ECSPI. While at it, oder the defines to improve readability and make adding more defines easier.
