ENGR00306442-1 ARM: imx6sx: Merge SPDIF and AUDIO clocks into one gate clock
On Solo X, SPDIF and AUDIO clocks shares one single gate to switch two
entirely different clock routes:
SPDIF <-- <---- SPDIF_PODF ----....
\ /
gate1
/ \
AUDIO <-- <---- AUDIO_PODF ----....
The two audio modules would easily cause conflict during clock operations
if running in the same time:
SPDIF <-- gate1 <---- SPDIF_PODF ----....
AUDIO <-- gate1 <---- AUDIO_PODF ----....
To keep them safe, we here have to merge them into one gate clock and limit
their rates and parent identical:
<---- SPDIF_PODF ----....
/
SPDIF, AUDIO <-- gate1
\
<---- AUDIO_PODF ----....
[ The only disadvantage of this modification is that we can not separately
set a different clock rates and clock sources to SPDIF and AUDIO clock. ]
