Subject: [PATCH v1 0/2] Allow vendor drivers to update UIC command timeout
Date: Wed, 22 May 2024 00:01:26 -0700	[thread overview]
Message-ID: <cover.1716359578.git.quic_nguyenb@quicinc.com> (raw)

The UIC command timeout default value remains as 500ms.

Allow vendor drivers to change the UIC command timeout as they wish.
During product development where a lot of debug logging/printing can
occur, the uart may print from different modules with interrupt disabled
for more than 500ms, causing interrupt starvation and UIC command timeout
as a result. The UIC command timeout may eventually cause a watchdog
timeout unnecessarily. With this change, the vendor drivers can set a
different UIC command timeout during their product development and
revert to the default 500ms when development completes as desired.
