From 5b21ec1b453f114e892ffa8f972f50339d6ee3fc Mon Sep 17 00:00:00 2001 From: Aseda Aboagye Date: Tue, 21 Jan 2020 23:21:40 -0800 Subject: pi3usb3x532: Pack i2c port in port_addr The PI3USB3X532 driver in the EC assumes that all superspeed muxes are on the same i2c bus, I2C_PORT_USB_MUX. However, that may not be true for some boards. This commit utilizes the MUX_PORT(...) macro to determine the i2c port to use from the usb_mux table. The boards that use this driver have been updated to pack the i2c port in the port_addr member. There should be no functional changes to those boards.
