| |
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.
