IOCTLs and rearranging `psmread', `psmioctl'... 51 * - 14, 30 November 1996. Uses `kbdio.c'. 52 * - 13 December 1996. Uses queuing version of `kbdio.c'. 53 * - January/February 1997. Tweaked probe logic for 54 * HiNote UltraII/Latitude/Armada laptops. 55 * - 30 July 1997. Added APM support. 56 * - 5 March 1997. Defined driver configuration flags (PSM_CONFIG_XXX). 57 * Improved sync check logic. 58 * Vendor specific support routines. 59 */ 60 61#include <sys/cdefs.h> 62__FBSDID("$FreeBSD: head/sys/dev/atkbdc/psm.c 178019 2008-04-08 19:09:45Z jkim $");
