The TLC5925 is a 16-channels constant-current LED sink driver.
It is controlled via SPI but doesn't offer a register-based interface.
Instead it contains a shift register and latches that convert the
serial input into a parallel output.

Sorry for my slowpokeness, but I just realized that this driver may
not be needed. What is the difference to existing gpio-74x164?

It might work. However it might not be as practical and efficient as the dedicated LED driver.

I'll give a try.
