[PATCH V2 05/12] dt-binding: serial: tegra: add new chips

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add new compatible string for Tegra186. It differs from earlier chips
as it has FIFO mode enable check and 8 byte DMA buffer.
Add new compatible string for Tegra194. Tegra194 has different error
tolerance levels for baud rate compared to older chips.
