| |
Hello. As part of the patch I sent that went into 2.6.0-test7 (Nat Semi SuperI/O chips on PPCs at least have a number of different divisors), the following should have been done as well, but wasn't. If we don't change the divisor, we don't want to change what we claim as the uart clock either. Without this I don't get a usable serial console on my Motorola Sandpoint.
