From mboxrd@z Thu Jan 1 00:00:00 1970 From: Simon Glass Date: Thu, 26 Mar 2015 09:29:27 -0600 Subject: [U-Boot] [PATCH v2 03/17] dm: x86: Add a uclass for a Platform Controller Hub In-Reply-To: <1427383781-7151-1-git-send-email-sjg@chromium.org> References: <1427383781-7151-1-git-send-email-sjg@chromium.org> Message-ID: <1427383781-7151-4-git-send-email-sjg@chromium.org> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de Add a simple uclass for this chip which is often found in x86 systems where the CPU is a separate device. The device can have children, so make it scan the device tree for these.
