From ba3451d3d8990fec10c1addc689448bd5b81dc62 Mon Sep 17 00:00:00 2001 From: Markus Niebel Date: Thu, 23 Oct 2014 16:09:38 +0200 Subject: SPI: mxc_spi: remove second reset from ECSPI config handler the second reset prevents other registers to be written. This will prevent to have the correct signal levels for SCLK before writing to the config reg in spi_xchg_single.
