CS can also be controlled automatically by setting AUTO_N_MANUAL to 1 in CS_CFG. When it is auto CS automatically toggles between packet to packet. NCS_TIME_COUNT in CS_CFG controls the inactive period. The driver by default uses manual mode. But on exynos7 the manual mode is removed.
OK, but what's a packet here?
I tested the driver with wm5110 codec.
Did you try firmware downloads or something else that generates multiple transfers in a message? Normal register writes will use a single transfer so I'd expect them to just work. -------------- next part -------------- A non-text attachment was scrubbed...
