Subject: [PATCH 0/2] Enhancements to UART driver for error handling and DMA RX status
Date: Mon, 12 Jan 2026 13:48:27 +0530 [thread overview]
Message-ID: <20260112081829.63049-1-m-shah@ti.com> (raw)
This series adds support for handling UART error conditions such as
overrun and other error conditions before any DMA transaction is
issued. It also ensures that the DMA RX running status is cleared
only after the DMA termination is fully done to maintain a sync between
software and the hardware states.
