From c49d07c2fd1c651af9f41742eae5522b59ff5497 Mon Sep 17 00:00:00 2001 From: Akshu Agrawal Date: Mon, 6 Jul 2020 19:38:16 +0530 Subject: soc/amd/picasso: set is_rv to 1 for RV family RV has difference in clk framework. In RV we get a 48Mhz fixed clk, while in ST we had 25Mhz, 48mhz clocks and a Mux to select between them. To differentiate set the fmw property to 1 for boards using RV family of SoC.
