From c8da642d41a6811c21177c9994aa7dc35be67d46 Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Mon, 17 Dec 2018 09:43:13 +0100 Subject: gpio: mvebu: only fail on missing clk if pwm is actually to be used MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The gpio IP on Armada 370 at offset 0x18180 has neither a clk nor pwm registers. So there is no need for a clk as the pwm isn't used anyhow. So only check for the clk in the presence of the pwm registers. This fixes a failure to probe the gpio driver for the above mentioned gpio device.
