From 776d7f1694a7d678291354a05f0243965708306a Mon Sep 17 00:00:00 2001 From: Alexey Brodkin Date: Mon, 16 May 2016 12:57:43 +0300 Subject: arc: axs103_smp: Fix CPU frequency to 100MHz for dual-core The most recent release of AXS103 [v1.1] is proven to work at 100 MHz in dual-core mode so this change uses mentioned feature. For that we: * Update axc003_idu.dtsi with mention of really-used CPU clock freq * Remove clock override in AXS platform code for dual-core HW Note we're still leaving a hack for clock "downgrade" on early boot for quad-core hardware. Also note this change will break functionality of AXS103 v1.0 hardware. That means all users of AXS103 __must__ upgrade their boards with the most recent firmware.
