Thanks for the response. While the TPS65224 drivers follow the format and structure of TPS6594, the register maps, masks, and ADC feature differ. The two PMICs have overlapping features but TPS65224 is not treated as a subset. TPS65224 is treated as a separate and independent driver instead of adding compatibility to the existing TPS6594 driver that would then support 3 PMICS. This separation will better support our differing PMICs.
Thanks & Regards, Sirisha G.
