From e7c310c36e5fdf1b83a459e5db167bfbd86137db Mon Sep 17 00:00:00 2001 From: Niels de Vos Date: Sun, 15 Jul 2007 23:41:35 -0700 Subject: [PATCH] parport_pc: it887x fix The IO port range requested by parport_pc.c:sio_ite_8872_probe is too small. The IO-ports of ttyS1 (0x2f8) will be missconfigured by the ITE-chip. The ITE starts looking for the chip a 0x2a0. An IO-portrange of 32 will not overwrite the ports of ttyS1. Therefore register 0x60 should be written with 0xe5000000, enabling the ITE and setting IO-portsize to 32 bytes.
