mfd: tps65219: Implement LOCK register handling for TPS65214

2026-03-04T12:21:22+00:00

[ 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: 7947219ab1a2d ("mfd: tps65219: Add support for TI TPS65214 PMIC") Reviewed-by: Andrew Davis Signed-off-by: Kory Maincent (TI.com) Link: https://patch.msgid.link/20251218-fix_tps65219-v5-1-8bb511417f3a@bootlin.com Signed-off-by: Lee Jones Signed-off-by: Sasha Levin

mfd: tps65219: Remove another unused field from 'struct tps65219'

The 'chip_id' field from 'struct tps65219' is unused. Remove it. Signed-off-by: Christophe JAILLET Link: https://lore.kernel.org/r/f20443e6e13b0b101648a41010a19ee56589fa0b.1750530460.git.christophe.jaillet@wanadoo.fr Signed-off-by: Lee Jones

mfd: tps65219: Remove an unused field from 'struct tps65219'

2025-07-24T10:27:08+00:00

Since commit 3df4c6367520 ("mfd: tps65219: Add support for soft shutdown via sys-off API"), the 'nb' field from 'struct tps65219' is unused. Remove it. Also remove the now useless #include for the same reason.

The TPS65219 is a power management IC PMIC designed to supply a wide range of SoCs in both portable and stationary applications. Any SoC can control TPS65219 over a standard I2C interface. It contains the following components: - Regulators. - Over Temperature warning and Shut down. - GPIOs - Multi Function Pins (MFP) - power-button This patch adds support for tps65219 PMIC. At this time only the functionalities listed below are made available: - Regulators probe and functionalities - warm and cold reset support - SW shutdown support - Regulator warnings via IRQs - Power-button via IRQ Signed-off-by: Jerome Neanne Signed-off-by: Markus Schneider-Pargmann Signed-off-by: Lee Jones Link: https://lore.kernel.org/r/20221104152311.1098603-5-jneanne@baylibre.com
