+Description: This file assigns power management control ownership.
+ When power management control is provided by hardware, hardware
+ will automatically power off one or more line previously
+ powered line cards in case system power budget is getting
+ insufficient. It could be in case when some of power units lost
+ power good state.
+ When pm_mgmt_en is written 1, power management control by
+ software is enabled, 0 - power management control by hardware.
+ Note that for any setting of pm_mgmt_en attribute hardware will
+ not allow to power on any new line card in case system power
+ budget is insufficient.
+ Same in case software will try to power on several line cards
+ at once - hardware will power line cards while system has
+ enough power budget.
+ Default is 0.

+Contact: Vadim Pasternak <vadimp@nvidia.com>
+Description: This file allows to unlock ASIC after thermal shutdown event.
+ When system thermal shutdown is enforced by ASIC, ASIC is
+ getting locked and after system boot it will not be available.
+ Software can decide to unlock it by setting this attribute to
+ 1 and then perform system power cycle by setting pwr_cycle
+ attribute to 1 (power cycle of main power domain).
+ Before setting shutdown_unlock to 1 it is recommended to
+ validate that system reboot cause is reset_asic_thermal or
+ reset_thermal_spc_or_pciesw.
+ In case shutdown_unlock is not set 1, the only way to release
+ ASIC from locking - is full system power cycle through the
+ external power distribution unit.
+ Default is 1.
+
+ The file is read/write.
