From 8eec6e740b564ec5e1da59ab7070b89aa23c9973 Mon Sep 17 00:00:00 2001 From: "Russell King (Oracle)" Date: Fri, 16 Jun 2023 12:41:30 +0100 Subject: [PATCH] cpufreq: armada-8k: add ap807 support Add support for the Armada AP807 die to armada-8k. This uses a different compatible for the CPU clock which needs to be added to the cpufreq driver. This commit takes a different approach to the WindRiver patch "cpufreq: armada: enable ap807-cpu-clk" in that rather than calling of_find_compatible_node() for each compatible, we use a table of IDs instead.
