Subject: [PATCH RESEND v2 0/3] Add quirk for reading BD_ADDR from fwnode property
Date: Tue, 4 Dec 2018 12:16:12 -0800 [thread overview]
Message-ID: <20181204201615.245574-1-mka@chromium.org> (raw)
On some systems the Bluetooth Device Address (BD_ADDR) isn't stored
on the Bluetooth chip itself. One way to configure the address is
through the device tree (patched in by the bootloader). The btqcomsmd
driver is an example, it can read the address from the DT property
'local-bd-address'.
To avoid redundant open-coded reading of 'local-bd-address' and error
handling this series adds the quirk HCI_QUIRK_USE_BDADDR_PROPERTY to
retrieve the BD address of a device from the DT and adapts the
btqcomsmd and hci_qca drivers to use this quirk.
