From f4e14edf25661f32c9e7323d8a482b8632a6f47f Mon Sep 17 00:00:00 2001 From: Robert Jarzmik Date: Mon, 19 Sep 2016 21:12:13 +0200 Subject: ARM: sa11x0/pxa: acquire timer rate from the clock rate As both pxa and sa1100 provide a clock to the timer, the rate can be inferred from the clock rather than hard encoded in a functional call. This patch changes the pxa timer to have a mandatory clock which is used as the timer rate.
