Hi All,
> Subject: [PATCH v2 3/7] clk: imx8: Update imx8 clock driver
Sorry to bring back this topic.
This patch is not converting to CCF following Linux, but it could
satisfy u-boot usage and make more feature work.
I checked Linux i.MX8 CCF recently, although Linux upstream has i.MX8
CCF support, but NXP downstream has significantly reimplement the code.
So we could not take code directly from Linux upstream, because this
would introduce efforts in U-Boot after NXP downstream clk code upstreamed.
I have also tried to converting to use NXP downstream Linux ccf code in u-boot,
but there is an issue is some clks are root clks, no parents. However u-boot ccf
always requires a parent for a clk. Anyway there is still long time to upstream
nxp Linux downstream clk code to Linux.
I would hear your voice about U-Boot part. Proceed with current patch
or promoting CCF with NXP downstream clk?
Thanks,
Peng.
