[PATCH 00/14] serial: tegra: Tegra186 support and fixes

From: Krishna Yarlagadda
Date: Mon Aug 12 2019 - 07:28:39 EST


Series of patches adding enhancements to exising UART driver and adding
support for new chip Tegra186 and Tegra194.

Tegra186 uses GPCDMA for dma transfers which is still not available in
mainstream. However, it can work in PIO/FIFO mode and support added for it.
Also Tegra186 has a hardware issue where it does not meet tolernace +/-4% and
to work around it, device tree entries provided to adjust baud rate for a
particular range.
