Dear Trent Piepho, > 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.

I suspect this patch should also fix drivers/clk/mxs/clk-ssp.c then? > Signed-off-by: Trent Piepho <tpie...@gmail.com> > Cc: Marek Vasut <ma...@denx.de> > Cc: Fabio Estevam <fabio.este...@freescale.com> > Cc: Shawn Guo <shawn....@linaro.org> > --- > drivers/spi/spi-mxs.c | 1 - > 1 file changed, 1 deletion(-) > > diff --git a/drivers/spi/spi-mxs.c b/drivers/spi/spi-mxs.c > index 7218006..fc52f78 100644 > --- a/drivers/spi/spi-mxs.c > +++ b/drivers/spi/spi-mxs.c > @@ -587,7 +587,6 @@ static int mxs_spi_probe(struct platform_device *pdev) > > clk_prepare_enable(ssp->clk); > clk_set_rate(ssp->clk, clk_freq); > - ssp->clk_rate = clk_get_rate(ssp->clk) / 1000; > > stmp_reset_block(ssp->base); Best regards, Marek Vasut ------------------------------------------------------------------------------ Own the Future-Intel® Level Up Game Demo Contest 2013 Rise to greatness in Intel's independent game demo contest.
