Can you please test with commit 3ce71e1 ?

Also the pinctrl conflict of gpio54 should be resolved now with 3e0b908

Can you please test with commit 3ce71e1 ?

I tried it on 6.3 and the modem is enabled again. No idea if cellular actually works, though.
I can also try it on 6.4 if it's preferred.

Also the pinctrl conflict of gpio54 should be resolved now with 3e0b908

Perhaps we can try to move cd pinctrl to boards. torvalds/linux@dfbda20
Done in torvalds/linux@1dfe967

I also booted up my hammerhead and seems fine on mine as well. Thanks for reporting, I'm considering this fixed. Will send upstream soonish I hope.

perf: RISCV: Fix panic on pmu overflow handler
34b5678 
(1 << idx) of int is not desired when setting bits in unsigned long
overflowed_ctrs, use BIT() instead. This panic happens when running
'perf record -e branches' on sophgo sg2042.

drm/vmwgfx: Create debugfs ttm_resource_manager entry only if needed
eb08db0 
commit 4be9075 upstream.

The driver creates /sys/kernel/debug/dri/0/mob_ttm even when the
corresponding ttm_resource_manager is not allocated.
This leads to a crash when trying to read from this file.

Add a check to create mob_ttm, system_mob_ttm, and gmr_ttm debug file
only when the corresponding ttm_resource_manager is allocated.
