Subject: [PATCH v8 3/9] PCI: endpoint: functions/pci-epf-test: Add second entry
Date: Fri, 27 Apr 2018 12:59:58 +0100	[thread overview]
Message-ID: <c2b6cb8de2502e1b5352be3b6d687b1cb4b7033a.1524829928.git.gustavo.pimentel@synopsys.com> (raw)
In-Reply-To: <cover.1524829928.git.gustavo.pimentel@synopsys.com>
In-Reply-To: <cover.1524829928.git.gustavo.pimentel@synopsys.com>

Add a seconds entry on the pci_epf_test_ids structure that disables the
linkup_notifier parameter on driver for the DesignWare EP.

Allow DesignWare EPs that doesn't have linkup notification signal to work
with pcitest.

Update the binding documentation accordingly.
