This patch set is based Lukasz V3 CCF patchset, [PATCH v3 00/11] clk: Port Linux common clock framework [CCF] to U-boot (tag: 5.0-rc3) https://github.com/lmajewski/u-boot-dfu/commits/CCF-v3
Added a few fixes to Lukasz's v3 patchset. Introduced clk-gate/composite Added set rate support Per my understanding, U-Boot CCF will not support mux reparent, and support rate prograte setting to parent automatically. So new clk feature added follow this rule.
There are many warnings when importing linux ccf code, I did not modify them all.
The rest patches are for i.MX8MM, part of legacy clk code are still kept, because we are hard to enable CCF at very early stage, we set malloc space to DRAM when dram initialized in spl stage, so we have limited SRAM for uclass dm and dm clk, so keep the DRAM PLL related setting with legacy clk code which use small ram.
The u-boot-spl.bin now is about 100KB without ddr firmware,usb stack and hab, so really large...... I am thinking what we could do to shrink the size, welcome any suggestions.
Not expect this patchset could be merged, because of the CCF/clock code change, but since the clock part blocks i.MX8MM upstream, just would like to speed up the development with community and move on.
