Following my comment related to ESM_MCU interrupts for 'tps6594.h':
Does it really make sense to add tps65224 ESM_MCU support in linux ?

For tps6594. TI requested a linux driver for ESM_SOC only (the "main" ESM).
No linux driver was requested for ESM_MCU.

Since tps65224 does not have ESM_SOC, I'm not sure that anything should
be done in linux for tps65224 ESM. Maybe you should discuss this point with
TI analog team (our TI contact for tps6594 was Chris Sterzik).
