Before discussion begins I would like to give my kudos to you Boris!
This is huge work and I thank you for it: It is so great!
I am sure that Jean-Christophe will have his idea on that because he
told me that he thought a little bit about that, but I am sure that we
will come to a quick and seamlessly integration soon.
(Hey, I know it is not technical email, but I am so exited to see this
happen that the noise worth it! ;-))
> 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.
