| 10 | Commit 4539c24fe4f92c09ee668ef959d3e8180df619b9 "tty/serial: Add | |
| 11 | explicit PORT_TEGRA type" introduced separate flags describing the need | |
| 12 | for IER bits UUE and RTOIE. Both bits are required for the XSCALE port | |
| 13 | type. While that patch updated uart_config[] as required, the auto-probing | |
| 14 | code wasn't updated to set the RTOIE flag when an XSCALE port type was | |
| 15 | detected. This caused such ports to stop working. This patch rectifies | |
| 16 | that. | |
