mvebu fixes for v3.8-rc6 (round 2)
This series of four patches started with Simon Baatz reporting lost MAC
addresses when compiling mv643xx_eth as a module. Accompanying that, he was
getting hard lockups on boot when most other drivers were compiled as modules.
All of this boiled down to gated clocks. mv643xx_eth looses it's mac address
after it's clock gets gated. The patch included in this series prevents the
ge0 and ge1 clocks from being gated when doing legacy platform init of the
driver.
There is another patch to accompany the DT conversion of the driver which will
allow reading the mac address from the devicetree. This patch is not included
here because the bindings are being added for v3.9.
The hard lockups at boot were the result of many SoC IPs using the runit gate
clock. Several drivers (gpio, rtc) were not claiming the clock, and of_serial
wouldn't claim the clock if clock-frequency was specified in the DT.
clock-frequency was only necessary before we added proper clock support, it is
now removed from all kirkwood dts files.
Last, proper clock support is added to gpio-mvebu and rtc-mv.
With these four fixes all drivers that can be compiled as modules can be
without breaking bootup.
