From 664ed4e283926d753e876a1347b7729135a3f6b8 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Thu, 20 Apr 2017 21:43:38 +0200 Subject: [PATCH] ARM: dts: Add clocks to the Gemini SoC We have a clock controller for the Gemini SoC, so make use of the driver and add clocks to the peripherals. Remove the hard-coded frequency from the UART and add switch the timer compatible to the generic that uses the clock framework for clock speed look-up.
