This patch series is a proposal to move at91 clock implementation to common clk framework. Most of the clock provided by the PMC (Power Management Controller) are implemented : - main clock (main oscillator) - pll clocks - master clock - programmable clocks - utmi clock - peripheral clocks - system clocks This implementation is compatible with device tree: the goal is to define the whole clock tree in the device tree (all currently available dt SoCs and boards are patched to support dt clocks). Please feel free to comment the dt bindinds (I'm not sure about the name I choose or the position of clock nodes: children of pmc node). I removed the register_clocks function in SoC supporting dt boards only: - at91sam9x5 SoCs - at91sam9n12 SoC - sama5d3 SoCs This patch series also update at91 drivers calling clk_enable/disable instead of the preferred clk_prepare_enable/disable_unprepare functions. I know there are a lot of cleanup in progress for at91 arch, so please tell me if you think this transition to common clk framework should wait. This patch series has been tested on Kizbox (sam9g20 SoC) board using device tree. It compiles for other SoCs and both with and without dt support, but it has not been tested. The clocks rate/parent change has not been tested.
