ACPI / tools: Introduce ec_access.c - tool to access the EC
This userspace tool accesses the EC through the ec_sys debug driver (through /sys/kernel/debug/ec/ec0/io). The EC command/data registers cannot be accessed directly, because they may be manipulated by the AML interpreter in parallel. The ec_sys driver synchronizes user space (debug) access with the AML interpreter. Signed-off-by: Thomas Renninger <trenn@suse.de> [rjw: Changelog] Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
