Before this patch, the Type-C port on the Sapphire board is dead. Applying only the power supply part of this patch, makes the port work for about 4 seconds at start-up. This is a sample trace with a memory stick plugged in: 1.- The memory stick LED lights on and kernel reports: [ 4.782999] scsi 0:0:0:0: Direct-Access USB DISK PMAP PQ: 0 ANSI: 4 [ 5.904580] sd 0:0:0:0: [sdb] 3913344 512-byte logical blocks: (2.00 GB/1.87 GiB) [ 5.906860] sd 0:0:0:0: [sdb] Write Protect is off [ 5.908973] sd 0:0:0:0: [sdb] Mode Sense: 23 00 00 00 [ 5.909122] sd 0:0:0:0: [sdb] No Caching mode page found [ 5.911214] sd 0:0:0:0: [sdb] Assuming drive cache: write through [ 5.951585] sdb: sdb1 [ 5.954816] sd 0:0:0:0: [sdb] Attached SCSI removable disk 2.- 4 seconds later the memory stick LED lights off and kernel reports: [ 9.082822] phy phy-ff770000.syscon:usb2-phy@e450.2: charger = USB_DCP_CHARGER 3.- After a minute the kernel reports: [ 71.666761] usb 5-1: USB disconnect, device number 2 It has been checked that, although the LED is off, VBUS is present. Applying the full patch makes it work. It has only been tested in host mode.
