This patchset implements a clock driver for STM32F42xxx and STM32F43xxx
series devices.
There are a few small caveats at the present:
1. Relies on "Add support to STMicroeletronics STM32 family", v8 by
Maxime Coquelin:
http://thread.gmane.org/gmane.linux.kernel.cross-arch/27569
2. Allocating ~80 clock components appears to fragment memory enough
to prevent busybox (.text is ~300K, non-XIP) from running getty.
I have to use "init=/bin/sh" to avoid OOM problems.
3. Support for I2S and SAI is not included in this patchset.
