[CPUFREQ] Longhaul - Replace ACPI functions with direct I/O

Browse source

Current version of "bm status" bit test works as long as
no USB device is in use. When USB device is plugged in ACPI
function in this context is always returning 1. Until reboot.
Direct I/O is working fine even when many USB devices are
connected.
Change bm_timeout value to less annoying. 1000 is still much
more then worst case observed and it is much better when status
bit gets stuck.
