- 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.
