From 43b41566f72c3ff1074fe686f37227ebe33e11f9 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 16 Apr 2017 21:01:11 -0600 Subject: dm: sandbox: pwm: Add a basic pwm test Unfortunately a test for the PWM uclass was not included when it was submitted. This was noticed when trying to add more functionality: http://patchwork.ozlabs.org/patch/748172/ Add a simple test to get us started.
