Subject: [PATCH 06/18] ARM: zynq: zedboard: provide DTB
Date: Thu,  7 Nov 2019 22:11:07 +0100	[thread overview]
Message-ID: <20191107211119.68064-7-dev@lynxeye.de> (raw)
In-Reply-To: <20191107211119.68064-1-dev@lynxeye.de>

Provide the DTB to allow devices to be probed from there,
instead of board code.
