From 331c37221057e6a1291b6e14d9f033a7a90051f1 Mon Sep 17 00:00:00 2001 From: Marek Vasut <marex@denx.de> Date: Sat, 18 Aug 2018 16:00:31 +0200 Subject: [PATCH] ARM: socfpga: Convert Arria10 to timer framework Switch the Arria10 from ad-hoc hardcoded timer to timer framework and the DW APB timer driver. This allows the A10 to extract timer information, like timer rate, from clock framework and thus DT instead of having it hardcoded in U-Boot configuration files.
