Hi Balakrishna,
During hci down we are sending reset command to chip, which
is not required for wcn3990, as hdev->shutdown() will turn off the
regulators.

I am pretty certain that you didn’t want this quirk:
/* When this quirk is set, the HCI Reset command is send when
* closing the transport instead of when opening it.
This quirk is for Bluetooth 1.0b devices where the HCI_Reset behavior
was not clear or for devices that actually misbehave with the initial
HCI_Reset.
In addition, you commit message is totally misleading. That is not
what is happening with this quirk.

My intention was reset command is not required when we do an hci down.
this is because of hdev->shutdown will turn off the regulators.
It is like turning off the chip. sending reset command after turning off
the chip is not required.
I understand the usage of the quirk, will update the commit text.
