Subject: [PATCH 1/2] [net,v3] net: wwan: t7xx: add PM_AUTOSUSPEND_MS_BY_DW5933E for Dell DW5933e
From: Jack Wu <wojackbb@...il.com>
Because optimizing the power consumption of Dell DW5933e,
Add a new auto suspend time for Dell DW5933e.
The Tests uses a small script to loop through the power_state
of Dell DW5933e.
(for example: /sys/bus/pci/devices/0000\:72\:00.0/power_state)
* If Auto suspend is 20 seconds,
test script show power_state have 5% of the time was in D3 state
when host don't have data packet transmission.
* Changed auto suspend time to 5 seconds,
test script show power_state have 50% of the time was in D3 state
when host don't have data packet transmission.

V2:
