Subject: [PATCH v3 0/5] Allwinner H6 GPU devfreq

Hi,

This is a refresh of previous patches sent to enable GPU Devfreq on H6
Beelink GS1 but that wasn't stable at that time[0].

With the recent fix on GPU PLL from Roman Stratiienko I have retested
and everything seems stable and works as expected[1].

Regards,
Clement
