Merge tag 'regulator-v6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator
Pull regulator updates from Mark Brown: "This is a very quiet release, there was no work on the core and a good chunk of the updates were the result of conversions to use newer GPIO APIs. We did gain support for Analog ADP5055 and TI TPS65214 devices, and there's a new restart handler for the PCA9450 which allows devices using it to be properly power cycled on reboot, but otherwise it's minor fixes and API updates" * tag 'regulator-v6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator: (24 commits) regulator: qcom_spmi: Constify struct spmi_voltage_range regulator: max8952: Correct Samsung "Electronics" spelling in copyright headers regulator: dt-bindings: mt6357: Drop fixed compatible requirement regulator: gpio: Use dev_err_probe regulator: pca9450: Add restart handler regulator: da9121: Fix Wvoid-pointer-to-enum-cast warning regulator: tps65219: Add TI TPS65214 Regulator Support regulator: tps65219: Add support for TPS65215 Regulator IRQs regulator: tps65219: Add support for TPS65215 regulator resources regulator: tps65219: Update struct names regulator: pf9453: convert to use maple tree register cache regulator: max20086: Change enable gpio to optional regulator: max20086: Fix MAX200086 chip id regulator: adp5055: Remove unneeded semicolon regulator: adp5055: remove duplicate device table regulator: adp5055: Add driver for adp5055 regulator: dt-bindings: adi,adp5055-regulator: Add adp5055 support regulator: don't compare raw GPIO descriptor pointers regulator: rpi-panel-attiny: use new GPIO line value setter callbacks regulator: rpi-panel-attiny: use lock guards for the state mutex ...
