From 3fbeef397212046cc514fe9fcd07e67e6ca32163 Mon Sep 17 00:00:00 2001 From: Adam Ford Date: Wed, 11 Sep 2019 19:47:13 +0200 Subject: [PATCH] cpufreq: ti-cpufreq: Add support for AM3517 The AM3517 only lists 600MHz @ 1.2V, but the register values for 0x4830A204 = 1b86 802f, it seems like am3517 might be a derivative of the omap36 which OPPs would be OPP50 (300 MHz) and OPP100 (600 MHz). This patch simply adds the am3517 to the compatible table similar to a mix of the omap3430 and omap3430 structure.
