Subject: [PATCH 00/14] serial: tegra: Tegra186 support and fixes
Date: Mon, 12 Aug 2019 16:58:09 +0530	[thread overview]
Message-ID: <1565609303-27000-1-git-send-email-kyarlagadda@nvidia.com> (raw)

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.

Ahung Cheng (2):
  serial: tegra: avoid reg access when clk disabled
  serial: tegra: protect IER against LCR.DLAB

Andreas Abel (1):
  serial: tegra: add internal loopback functionality

Krishna Yarlagadda (7):
  serial: tegra: report error to upper tty layer
  serial: tegra: add compatible for new chips
  serial: tegra: check for FIFO mode enabled status
  serial: tegra: DT for Adjusted baud rates
  serial: tegra: add support to adjust baud rate
  serial: tegra: report clk rate errors
  serial: tegra: Add PIO mode support

Shardar Shariff Md (4):
  serial: tegra: add support to ignore read
  serial: tegra: flush the RX fifo on frame error
  serial: tegra: set maximum num of uart ports to 8
  serial: tegra: add support to use 8 bytes trigger
