The allocation for the audio pmc is using the size of struct clk_audio_pad
instead of struct clk_audio_pmc. This works fine because the former is
larger than the latter but it is safer to be correct.

I would use a clearer name for that property like isil,ev-pull-up-enabled.
Also make it an int so 0 is disabling the pull-up (EVIENB set to 1) 1 is
enabling the pull-up (EVIENB set to 0) and do nothing when the property
is not present.

I guess this is because

There is now only on defconfig for the at91rm9200 and at91sam9. Add ethernet
support for the rm9200.

This patch sets cleans up the system timer driver.
The main goal is to get rid of the mach/ headers dependency. At the same time,
it introduces proper probing and locking (using a regmap) for the watchdog
driver.

I think we should actually stop checking those

I would fix that by not calling suspend_set_ops(&at91_pm_ops) when
slow_clock is NULL

I would prefer not to miss 3.20, can I resend the patches now so you can
review and ack them? Then they could go through the mfd tree.
