From b05f15d0fc15a21ffe480226b02d9352bddfa2e5 Mon Sep 17 00:00:00 2001 From: Ryan Walklin Date: Fri, 7 Jun 2024 21:20:34 +1200 Subject: [PATCH] arm64: dts: allwinner: h616: add additional CPU OPPs for the H700 The H700 now shows stable operation with the 1.008, 1.032 and 1.512 GHz DVFS operating points. The 1.5GHz OPP requires a VDD-CPU of 1.16V, obtained from the vendor BSP. This voltage is slightly above the recommended operating voltage for the H616 (H700 datasheet not publicly available) but well within the absolute maximum of 1.3V. Add the additional 1.032 GHz operating point to the H616 CPU-OPP table, and enable the 1.008 and 1.512 points for the H700.
