From ebae33c3f6cee978f60ad48371258a03f9440691 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Cl=C3=A9ment=20P=C3=A9ron?= Date: Mon, 20 Apr 2020 15:00:18 +0200 Subject: [PATCH] arm64: dts: allwinner: h6: Enable CPU opp tables for Orange Pi 3 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Enable CPU opp tables for Orange Pi 3. This needs to change the CPU regulator max voltage to fit the OPP table. Also add the ramp-delay information to avoid any out of spec running as the regulator is slower at reaching the voltage requested compare to the PLL reaching the frequency. There is no such information for AXP805 but similar PMIC (AXP813) has a DVM (Dynamic Voltage scaling Management) ramp rate equal to 2500uV/us.
