This series adds the support for two optional DT properties to configure RX and TX FIFO thresholds: - rx-threshold - tx-threshold This replaces hard-coded 8 bytes threshold. No functional change expected if unspecified (keep 8 as default).
Changes in v2: Change added properties naming and factorize it in serial.yaml as proposed by Rob Herring.
Erwan Le Ray (3): dt-bindings: serial: add RX and TX FIFO properties dt-bindings: serial: stm32: override FIFO threshold properties dt-bindings: serial: 8250: update TX FIFO trigger level
