   3 Subject: [PATCH] brcmfmac: sdio: Increase the default timeouts a bit
   4
   5 On a Radxa Rock2 board with a Ampak AP6335 (Broadcom 4339 core) it seems
   6 the card responds very quickly most of the time, unfortunately during
   7 initialisation it sometimes seems to take just a bit over 2 seconds to
   8 respond.
   9
  10 This results intialization failing with message like:
  11   brcmf_c_preinit_dcmds: Retreiving cur_etheraddr failed, -52
  12   brcmf_bus_start: failed: -52
  13   brcmf_sdio_firmware_callback: dongle is not responding
  14
  15 Increasing the timeout to allow for a bit more headroom allows the
  16 card to initialize reliably.
  17
  18 A quick search online after diagnosing/fixing this showed that Google
  19 has a similar patch in their ChromeOS tree, so this doesn't seem
  20 specific to the board I'm using.
