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.
Nadeem Athani (2): dt-bindings:pci: Set LTSSM Detect.Quiet state delay. PCI: cadence: Set LTSSM Detect.Quiet state delay.
