From 1a33073fcf11e70447b704c0228e28099e6ab39d Mon Sep 17 00:00:00 2001 From: Trent Piepho Date: Tue, 1 Oct 2013 13:15:18 -0700 Subject: [PATCH] spi: spi-mxs: Remove bogus setting of ssp clk rate field The ssp struct has a clock rate field, to provide the actual value, in Hz, of the SSP output clock (the rate of SSP_SCK) after mxs_ssp_set_clk_rate() is called. It is set by mxs_ssp_set_clk_rate(), for SSP using drivers (like SPI and MMC) to *read* if they want to know the actual clock rate. The SPI driver isn't supposed to *write* to it. For some reason the spi-mxs driver decides to write to this field on init, and sets it to the value of the SSP input clock (clk_sspN, from the MXS clocking block) in kHz. It shouldn't be setting the value, and certainly shouldn't be setting it with the wrong clock in the wrong units.
