Hi,
set of patches based on next.
It's required:
[PATCH] clkdev: add helper function to register one clock lookup for a struct clk
Best regards,
Carlo Caione (5):
BCM2835: add clocksource driver
BCM2835: add gpio driver
ARM1176: add support
BCM2835: add support (arch)
Raspberry-Pi: add support (board)
