Backport of Stanislaw Pal's (kuncy7) fix for the ipq_cmn_pll_clk_probe() boot race that silently hangs the ipq5018 SoC. Applied upstream as openwrt/openwrt@86b584bd0994 (PR openwrt#24653), but not present in this tree's 6.12 stack. Without it, an NSS-enabled ipq5018 image does not reach userspace on the AX6000. Signed-off-by: Augusto Amaral <contact@augustoamaral.com>

Backport of @kuncy7's CMN PLL fix, already in openwrt/openwrt main (applied manually by robimarko as openwrt/openwrt@86b584bd0994 in
patches-6.18/, from openwrt#24653) but not yet in this tree's 6.12 stack. The probe takes a runtime PM reference and pm_clk gates the GCC AHB/SYS bus clocks asynchronously a few ms after probe — a boot race that silently hangs the SoC on ipq5018 when the NSS/UNIPHY nodes are enabled. It ranges from an occasional hang to a fully reproducible boot loop depending on the binary layout.On the AX6000, the NSS-enabled image (#113/#114/#115) does not boot at all without this — I hit the hang on hardware and confirmed the fix (Tested-by on the upstream PR). Added as
patches-6.12/0192-…; the full CMN patch sequence (0063–0069, 0190, 0192, 0913–0916) applies cleanly with it in place. It will also arrive naturally with the next rebase onto openwrt main — until then, ipq5018 NSS builds need it to boot.Re-opened as a new PR: the original was closed automatically by GitHub when my fork got detached. Same content, new fork.
