From 75ab939394fd0b262ad4b5625a55c2895a73c065 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Wed, 27 Jun 2018 10:27:09 +0800 Subject: ARM: dts: sun8i: a83t: Add CPU regulator supplies for A83T boards The OPPs for the A83T CPU cores were added in v4.17 in commit 2db639d8c166 ("ARM: dts: sun8i: a83t: add stable OPP tables and CPUfreq"), but board level regulator supplies for the CPU clusters were only added for the TBS-A711 tablet. This means the other A83T boards do not benefit from voltage scaling, or worse, if the implementation does not scale the frequency when the voltage is fixed, no benefit at all. Add board level CPU cluster power supplies to all the A83T development boards, so they can have proper dynamic CPU voltage and frequency scaling.
