Subject: [RFC PATCH 0/3] clk: stm32: Add clock driver for STM32F4[23]xxx devices
Date: Fri, 22 May 2015 21:41:10 +0100	[thread overview]
Message-ID: <1432327273-6810-1-git-send-email-daniel.thompson@linaro.org> (raw)

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.
