Subject: [PATCH 3/3] ARM: dts: aspeed: ventura2: Name the USB-UART bridge reset GPIOs
Date: Fri, 06 Nov 2026 11:08:04 +0800 [thread overview]
Message-ID: <20261106-ventura2-dts-update-v1-3-b085ece9bf57@gmail.com> (raw)
In-Reply-To: <20261106-ventura2-dts-update-v1-0-b085ece9bf57@gmail.com>
Lines 2-4 of the PCA9555 at address 0x20 on I2C bus 6 drive the reset
of the three USB-to-UART bridges. Name them RST_FT4232_{1,2,3}_BMC_N_R
after the schematic nets so userspace can reset the bridges.
