Re: (subset) [PATCH v5 1/2] mfd: tps65219: Implement LOCK register handling for TPS65214

The TPS65214 PMIC variant has a LOCK_REG register that prevents writes to nearly all registers when locked. Unlock the registers at probe time and leave them unlocked permanently.

This approach is justified because:

• Register locking is very uncommon in typical system operation
• No code path is expected to lock the registers during runtime
• Adding a custom regmap write function would add overhead to every register write, including voltage changes triggered by CPU OPP transitions from the cpufreq governor which could happen quite frequently

[...]

Applied, thanks!
