From 93fff4ce19f9978cc1c59db42760717477939249 Mon Sep 17 00:00:00 2001 From: Jason Cooper Date: Tue, 29 Jan 2013 20:36:43 +0000 Subject: ARM: kirkwood: of_serial: fix clock gating by removing clock-frequency When DT support for kirkwood was first introduced, there was no clock infrastructure. As a result, we had to manually pass the clock-frequency to the driver from the device node. Unfortunately, on kirkwood, with minimal config or all module configs, clock-frequency breaks booting because of_serial doesn't consume the gate_clk when clock-frequency is defined. The end result on kirkwood is that runit gets gated, and then the boot fails when the kernel tries to write to the serial port. Fix the issue by removing the clock-frequency parameter from all kirkwood dts files. Booted on dreamplug without earlyprintk and successfully logged in via ttyS0.
