Return to serial.h CVS log

Up to [Development] / linux-2.6-xfs / include / asm-arm / arch-iop3xx

Upgrade kernel to 2.6.9-rc3 and kdb to 4.4
Merge of 2.6.x-xfs-melb:linux:19628a by kenmcd.

/*
 * This assumes you have a 1.8432 MHz clock for your UART.
 *
 * It'd be nice if someone built a serial card with a 24.576 MHz
 * clock, since the 16550A is capable of handling a top speed of 1.5
 * megabits/second; but this requires the faster clock.
