(I don't know any of these platforms well) I did some looking the other day, and I had forgotten that the RPi has 3 of the i2c-bcm2835 devices each with their own divider that sits in their register space. This makes me think the correct solution would be for the divider to be controlled in the driver as was in my original patch. Otherwise we’d have to make three different dividers in the bcm2835-clk driver, and the i2c driver would no longer work for other platforms. I haven’t heard any comments from any of the clock folks. I was perusing the code and I see there’s a SPI driver that registers its own clock and some various ethernet and MMC drivers that do the same thing. > Regards, > > Wolfram -- Annaliese McDermond nh6z@xxxxxxxx
