Subject: [PATCH RFC 3/3] ARM64: bcm2837-rpi: Fix pwm and i2c pin control
Date: Thu, 16 Feb 2017 21:20:47 +0000	[thread overview]
Message-ID: <1487280047-29608-4-git-send-email-stefan.wahren@i2se.com> (raw)
In-Reply-To: <1487280047-29608-1-git-send-email-stefan.wahren@i2se.com>

According to the firmware DT blob [1] the RPi 3 uses different
pins for i2c0 and pwm.
