Hi Vinod,

I've sent the DT series a while back (before resending). Usually I
propose DT changes through Krzysztof's tree. The patches are 
unchanged (they will be resent unchanged when all usb and wdt 
changes are merged).

Here is the patchset:
- on patchwork: https://patchwork.kernel.org/project/linux-samsung-soc/patch/20250217-exynos990-dt-changes-febuary-v1-2-99935218cbf4@mentallysanemainliners.org/
- on the mailing list archives: https://lore.kernel.org/all/20250217-exynos990-dt-changes-febuary-v1-2-99935218cbf4@mentallysanemainliners.org/

Best regards
