[PATCH] spi/imx: set the inactive state of the clock according to the clock polarity

2012-08-31 Thread Dirk Behme
From: Knut Wohlrab knut.wohl...@de.bosch.com There are SPI devices which need a SPI clock with active low polarity and high inactive state. Add the setting of the inactive state ECSPIx_CONFIGREG:SCLK CTL according to the clock polarity ECSPIx_CONFIGREG:SCLK POL: DT without spi-cpol = 0 = clock

[PATCH 4/4] ARM: OMAP1: Move SoC specific headers from plat to mach for omap1

2012-08-31 Thread Tony Lindgren
There's no need to have these in plat-omap any longer. Note that these could eventually be made local to mach-omap1 instead of being in mach. But to do that, at least various driver access using omap7xxx.h registers needs to be fixed first. Cc: spi-devel-general@lists.sourceforge.net Cc: Grant
