Kory Maincent (TI.com) 89bdcd39ae mfd: tps65219: Implement LOCK register handling for TPS65214 ... [ Upstream commit d3fcf276b501a82d4504fd5b1ed40249546530d1 ] 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 Cc: stable@vger.kernel.org Fixes: 7947219ab1 ("mfd: tps65219: Add support for TI TPS65214 PMIC") Reviewed-by: Andrew Davis <afd@ti.com> Signed-off-by: Kory Maincent (TI.com) <kory.maincent@bootlin.com> Link: https://patch.msgid.link/20251218-fix_tps65219-v5-1-8bb511417f3a@bootlin.com Signed-off-by: Lee Jones <lee@kernel.org> Signed-off-by: Sasha Levin <sashal@kernel.org>		2026-03-04 07:21:12 -05:00
