Hi Dirk-san, Wolfram-san,
And third, from reading the r8a7795 manual I think the manual talks about
https://github.com/dirkbehme/linux-renesas-rcar-gen3/commit/f2a727c859916d59dca85dbb72c1b61da3fd6da0
But testing this it doesn't work. So either the manual is wrong, or I missed
anything else.
I have seen this patch and my gut feeling is that it won't make a
difference? SCLKDIVEN is like CBUSY plus some more cycles AFAIU. But I
am not working on DMA issues now, this has to wait.
I'm not sure we have to use CBSY bit instead of SCLKDIVEN on r8a7795.
The r8a7795 manual I have has several
"Do / Do not xxx when the CBSY bit in SD_INFO2 is set to x"
It always talks about CBSY, not SCLKDIVEN.
Best regards
Dirk
