Subject: [PATCH 0/2] serial: 8250_dw: Add ti,tda54-uart support
Date: Fri, 11 Sep 2026 14:55:27 +0530 [thread overview]
Message-ID: <20260911092529.306082-1-m-shah@ti.com> (raw)
Add the ti,tda54-uart compatible string to the DW APB UART binding,
and add a quirk to skip the RX_TIMEOUT dummy read on TDA54.
Reading an empty FIFO on the IP version used in TDA54 triggers a
data abort. The interrupt storm this dummy read was meant to avoid
no longer occurs on this version of the IP, so skip the read via a
new quirk.
