In our case We've added an additional fake node to the device tree with UART MMIO range for Xen and Xen mapped this MMIO range for the Kernel 3.8. By default UART has wrong configuration in OMAP. Oleksandr Dmytryshyn | Product Engineering and Development GlobalLogic M +38.067.382.2525 www.globallo

[Xen-devel] [PATCH] xen/serial: setup UART idle mode for OMAP

2014-12-05 Thread Oleksandr Dmytryshyn
UART is not able to receive bytes when idle mode is not configured properly. When we use Xen with old Linux Kernel (for example 3.8) this kernel configures UART idle mode even if the UART node in device tree is absent. So UART works normally in this case. But new Linux Kernel (3.12 and upper) doesn
