Subject: [PATCH 07/14] serial: tegra: add compatible for new chips
Date: Mon, 12 Aug 2019 16:58:16 +0530 [thread overview]
Message-ID: <1565609303-27000-8-git-send-email-kyarlagadda@nvidia.com> (raw)
In-Reply-To: <1565609303-27000-1-git-send-email-kyarlagadda@nvidia.com>
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.
