Hi all,
I ported the FM radio driver [1] to a more recent and close to upstream kernel (Linaro 4.4), but I have a hard time using it.
Some commands never gets a reply, some others get a reply with an error status (usually 0x0c, which is translated by the driver as ‘-EBUSY’), and some works (actually, only HCI_FM_GET_RECV_CONF_CMD work without failure of all the commands I’ve tested so far).
Does anyone have info on the init sequence of the radio or any information that could help me get the driver in a working state?
[1] radio-iris.c\radio\media\drivers - kernel/msm-4.4 - Unnamed repository
Cheers,
Damien
