Although the previous version[1] is properly handled the clock gates with enable and disable management, but this series is trying to add some more complex Allwinner CLK architecture by handling parent clock and other CLK attributes.
Allwinner Clock control unit comprises of parent clocks, gates, multiplexers, dividers, multipliers, pre/post dividers and flags etc.
So, the U-Boot implementation of ccu has divided into gates and tree. gates are generic clock configuration of enable/disable bit management and these can be handled via ccu_clock_gate, which is almost same as previous version changes.
Tree clock has more Allwinner CLK attributes like clock type, fixed clocks, misc clocks, mp, nk, nkm, nkmp, pre/post div, flags etc and these can be managed via ccu_clock_tree.
On top of initial clock gates supported from previous version, this series is trying to add support for MP, NK, MISC, FIXED clock types with get_rate functionality and that can eventually used by uart driver.
On the summary, this would be an initial infrasture that can fit into remaining clock handle support like set_rate, so the rest of code will add on the requirement basics.
Once this is fine, I will try to add code for other parts especially for MMC since we have migration deadline for BLK, MMC, SCSI.
So, please do let me know if anyone have any inputs.
All these changes available at u-boot-sunxi/clk-next
thanks, Jagan.
