Subject: [PATCH 6.12.y 1/2] arm64: dts: ti: k3-j722s-evm: Fix USB2.0_MUX_SEL to select Type-C
Date: Fri, 15 Aug 2025 13:23:51 -0400 [thread overview]
Message-ID: <20250815172352.165389-1-sashal@kernel.org> (raw)
In-Reply-To: <2025081521-dangle-drapery-9a9a@gregkh>
From: Hrushikesh Salunke <h-salunke@ti.com>
[ Upstream commit bc8d9e6b5821c40ab5dd3a81e096cb114939de50 ]
J722S SOC has two usb controllers USB0 and USB1. USB0 is brought out on
the EVM as a stacked USB connector which has one Type-A and one Type-C
port. These Type-A and Type-C ports are connected to MUX so only
one of them can be enabled at a time.
Commit under Fixes, tries to enable the USB0 instance of USB to
interface with the Type-C port via the USB hub, by configuring the
USB2.0_MUX_SEL to GPIO_ACTIVE_HIGH. But it is observed on J722S-EVM
that Type-A port is enabled instead of Type-C port.
Fix this by setting USB2.0_MUX_SEL to GPIO_ACTIVE_LOW to enable Type-C
port.
Fixes: 485705df5d5f ("arm64: dts: ti: k3-j722s: Enable PCIe and USB support on J722S-EVM")
