Subject: [PATCH v2 2/2] pci: pcie: add dependency info to Kconfig
Date: Sun, 13 Nov 2022 22:28:11 +1100	[thread overview]
Message-ID: <20221113112811.22266-3-albert.zhou.50@gmail.com> (raw)
In-Reply-To: <20221113112811.22266-1-albert.zhou.50@gmail.com>

Thunderbolt and USB4 PCIe cards require the hotplug feature. This is now
recorded in the help message for HOTPLUG_PCI_PCIE. Further, PCIEPORTBUS
and HOTPLUG_PCI_PCIE are defaulted to Y if USB4 is selected.
