Subject: [PATCH] PCI: mt7621: increase PERST_DELAY_MS
Date: Sat, 19 Nov 2022 12:08:37 +0100 [thread overview]
Message-ID: <20221119110837.2419466-1-sergio.paracuellos@gmail.com> (raw)
Some devices using this SoC and PCI's like ZBT WE1326 and Netgear R6220 need
more time to get the PCI ports properly working after reset. Hence, increase
PERST_DELAY_MS definition used for this purpose from 100 ms to 500 ms to get
into confiable boots and working PCI for these devices.
Fixes: 475fe234bdfd ("staging: mt7621-pci: change value for 'PERST_DELAY_MS'")
