+Subject: [PATCH] brcmfmac: sdio: Increase the default timeouts a bit
+
+On a Radxa Rock2 board with a Ampak AP6335 (Broadcom 4339 core) it seems
+the card responds very quickly most of the time, unfortunately during
+initialisation it sometimes seems to take just a bit over 2 seconds to
+respond.
+
+This results intialization failing with message like:
+  brcmf_c_preinit_dcmds: Retreiving cur_etheraddr failed, -52
+  brcmf_bus_start: failed: -52
+  brcmf_sdio_firmware_callback: dongle is not responding
+
+Increasing the timeout to allow for a bit more headroom allows the
+card to initialize reliably.
+
+A quick search online after diagnosing/fixing this showed that Google
+has a similar patch in their ChromeOS tree, so this doesn't seem
+specific to the board I'm using.
