| |
2.6.31-stable review patch. If anyone has any objections, please let us know.
------------------ From: Michal Simek <monstr@monstr.eu>
commit 16173c7c2d79da7eb89b41acfdebd74b130f4339 upstream.
Many boards have a bug-free ns16550 compatible serial port, which we should register as PORT_16550A. This introduces a new value "ns16550a" for the compatible property of of_serial to let a firmware choose that model instead of using the crippled PORT_16550 mode.
