PD#SWPL-68630 Problem: porting thermal driver Solution: 1. porting thermal driver 2. modify the function type of the member of struct thermal_cooling_device_ops state2power power2state get_requested_power 3. modify the function(cpu_hotplug.c) interface cpu_up() --> add_cpu() cpu_down() --> remove_cpu() 4. modify config and move module_init from meson_cooldev.c to meson_tsensor.c 5. modify pr_info() --> pr_debug() when probe Verify: s4d Change-Id: I5eead0120dbc826cbb4282d28d7531018c826025 Signed-off-by: wanwei.jiang <wanwei.jiang@amlogic.com>
