Subject: [PATCH] brcmfmac: disable command decode in sdio_aos
|
|
|
|
|
|
|
|
|
|
AOS is a part of the SDIOD core that becomes active when the rest of
|
|
|
|
|
SDIOD is sleeping to keep SDIO bus alive responding to reduced set of
|
|
|
|
|
commands.
|
|
|
|
|
|
|
|
|
|
Transaction between AOS and SDIOD is not protected, and if cmd 52 is
|
|
|
|
|
received in AOS and in the middle of response state changed from AOS to
|
|
|
|
|
SDIOD, response is corrupted and it causes to SDIO Host controller to
|
|
|
|
|
hang.
|
|
|
|
|
|
|
|
|
|
Command decode for below chips are disabled in this commit:
