Subject: [PATCH v2 0/2] Add support for Tegra UART Trace Controller (UTC) client
Date: Tue, 11 Feb 2025 11:49:43 +0530 [thread overview]
Message-ID: <20250211061945.18836-1-kkartik@nvidia.com> (raw)
The Tegra UTC (UART Trace Controller) is a hardware controller that allows
multiple systems within the Tegra SoC to share a hardware UART interface.
It supports up to 16 clients, with each client having its own interrupt and a
FIFO buffer for both RX (receive) and TX (transmit), each capable of holding
128 characters.
The Tegra UTC uses 8-N-1 configuration and operates on a pre-configured
baudrate, which is configured by the bootloader.
