From d0686a02b98ee264532c25108edc3ba44acc1145 Mon Sep 17 00:00:00 2001 From: Sean Anderson Date: Thu, 8 Apr 2021 22:13:04 -0400 Subject: [PATCH] clk: k210: Fix PLLs not being enabled After starting or setting the rate of a PLL, the enable bit must be set. This fixes a bug where the AI ram would not be accessible, because it requires PLL1 to be running.
