From de6cc84f723ab4373d1f83e64771392d6f784c81 Mon Sep 17 00:00:00 2001 From: Russell King Date: Wed, 30 Aug 2006 15:30:39 +0100 Subject: [SERIAL] Remove m32r_sio dependency on asm/serial.h m32r_sio re-uses a custom defined BASE_BAUD from asm/serial.h, and replaces SERIAL_PORT_DFNS with its own driver private copy. Since asm/serial.h is supposed to define 8250-based ports using these symbols, this isn't a sane idea. Hence, eliminate asm/serial.h from m32r_sio.c.

I initially did the patch below a year ago for the Fedora kernel, and have been keeping it up to date since. I recently got the same thing happening on a vanilla kernel, so figured it was time to repost this.

These are implemented as serial interfaces, generally exposed in the ACPIPNP information on the system. This patch adds them to the 8250_pnp driver tables, avoiding the need to mess around with setserial to set them up. I haven't been able to confirm what FUJ02B5, FUJ02BA and FUJ02BB are. FUJ02B1 refers to the controller for the system hotkeys. FUJ02BC appears to be the last in the range - after this, they moved to Wacom-based systems.
