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.
