From bb0c6bb3b71cec4b00c3fb1c055f92ad05b905db Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Fri, 24 Mar 2017 22:32:33 +0100 Subject: [PATCH] clocksource: Augment bindings for Faraday timer It turns out that the Cortina Gemini timer block is just a standard IP block from Faraday Technology named FTTMR010. In order to make things clear and understandable, we rename the bindings with a Faraday compatible as primary and the Cortina gemini as a more specific case. For the plain Faraday timer we require two clock references, while the Gemini can keep it's syscon lookup pattern.
