Subject: [PATCH 0/2] stm32 usart add fifo threshold configuration
Date: Tue, 6 Apr 2021 09:21:20 +0200	[thread overview]
Message-ID: <20210406072122.27384-1-erwan.leray@foss.st.com> (raw)

This series adds the support for two optional DT properties, to configure
RX and TX FIFO thresholds:
 - st,rx-fifo-threshold-bytes
 - st,tx-fifo-threshold-bytes
This replaces hard-coded 8 bytes threshold. No functional change expected
if unspecified (keep 8 as default).

  dt-bindings: serial: stm32: add fifo threshold configuration
