Here's a series to add a real clock provider on Raspberry Pi. Previously, we've been using a mix of fixed clocks from clk-bcm2835.c (though some of them failed to get used by their intended consumers), and fixed-clock nodes in the DT.
This driver gives us the ability to enable/disable our clocks, and also lets us get and set frequency values. This will let us build a cpufreq driver (Andrea Merello has done some work on this front, and has a couple of options available), and get correct frequencies on the Raspberry Pi 2 without hardcoding new values. This branch can be found at: https://github.com/anholt/linux/tree/rpi-dt-clocks which also has a patch for the MMC clock which is not included yet due to a bug in the sdhci driver. The series applies on top of rpi-mailbox, whose code is currently out for review: http://lists.infradead.org/pipermail/linux-rpi-kernel/2015-May/001762.html -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
