From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Christian Hewitt Date: Tue, 17 Aug 2021 16:16:43 +0000 Subject: arm64: dts: meson: radxa-zero: add support for the usb type-c controller Radxa Zero uses an FUSB302 type-c controller, so lets enable it. NB: Polarity swapping via GPIO is not implemented in the current driver (see drivers/usb/typec/tcpm/fusb302.c) so it is not possible to handle GPIOAO_6 for USB3 polarity control. Includes: - arm64: dts: amlogic: fix interrupt storm from fusb302 on Radxa Zero it makes load average >1. use correct pin for interrupt from fusb302.
