From 3370b0af910166e387cf4b3faeaa8b5f0cb53f29 Mon Sep 17 00:00:00 2001 From: Sudeep Holla Date: Thu, 26 Feb 2015 11:47:57 +0000 Subject: [PATCH] usb: isp1760: add peripheral/device controller chip id As per the SAF1761 data sheet[0], the DcChipID register represents the hardware version number (0001h) and the chip ID (1582h) for the Peripheral Controller. However as per the ISP1761 data sheet[1], the DcChipID register represents the hardware version number (0015h) and the chip ID (8210h) for the Peripheral Controller. This patch adds support for both the chip ID values.
