Subject: [PATCH 0/2] PCI: cadence: Set LTSSM Detect.Quiet state delay.
Date: Tue, 9 Mar 2021 08:31:40 +0100 [thread overview]
Message-ID: <20210309073142.13219-1-nadeem@cadence.com> (raw)
This patch includes a set of two patches.
First patch for adding a new property detect-quiet-min-delay in yaml file.
Second patch programs the delay value in host pcie driver.
The parameter detect-quiet-min-delay can be used to program the minimum
time that LTSSM waits on entering Detect.Quiet state.
00 : 0us minimum wait time in Detect.Quiet state.
01 : 100us minimum wait time in Detect.Quiet state.
10 : 1000us minimum wait time in Detect.Quiet state.
11 : 2000us minimum wait time in Detect.Quiet state.
