To patch or not to patch ? this is the problem.

Hello to everyone.

everytime I boot my radxa zero 3W board I see these errors :

Unresolved linked clock found: clk_32k_pvtm

Unresolved linked clock found: usb480m_phy

Unresolved linked clock found: mpll

Unresolved linked clock found: i2s0_mclkin

Unresolved linked clock found: i2s1_mclkin

Unresolved linked clock found: i2s2_mclkin

Unresolved linked clock found: i2s3_mclkin

Unresolved linked clock found: gpu_pvtpll_out

Unresolved linked clock found: npu_pvtpll_out

Unresolved linked clock found: gmac0_clkin

Unresolved linked clock found: clk_gmac0_xpcs_mii

Unresolved linked clock found: clk_gmac1_xpcs_mii

Unresolved linked clock found: dummy

Are they "normal" ? Should I patch them ? I ask it because I'm porting the
vop2 driver on FreeBSD 15 as modules,but I get this error that I'm not able
to fix :

<6>[drm] Initialized rockchip 1.0.0 20201113 for rk_drm on minor 0


My theory is that it is caused by the missing / wrong clock driver (rk_clk)
since I see all those errors that seem to be tied to it. In addition, in
FreeBSD 14.2 it is embedded inside the kernel but on 15.0 I want to have it
as a module. Can someone explain in quick and easy terms what's missing ?
What's the real "nature" of the error "*rk_drm0: Cannot initialize frame
buffer -22" *

*Thanks.*
