From e964d463392d70d801c15f83d02e61671f35d549 Mon Sep 17 00:00:00 2001 From: Jack Chen Date: Mon, 2 Dec 2019 23:35:40 +0800 Subject: ARM: dts: rockchip: Add missing cpu operating points for rk3288-tinker The Tinker Board / S devices use a special chip variant called rk3288-c and use different operating points with a higher max frequency. So add the missing operating points for Tinker Board / S devices, also increase the vdd_cpu regulator-max-microvolt to 1400000 uV so that the cpu can operate at 1.8 GHz.
