The C6678_EVM use UCD9222RGZR for 1VAVS,
But we want to use TPS40400 the same as DM8168 for
the continued design.
Is it OK?Is the 1VAVS's driver of C6678 support the TPS40400?
TPS40400 can not support C6678.
TPS40400 use PMBus as input, but C6678 use for control pins VCNTL[3:0] as power contol output.
