2023-06-15mfd: tps65219: Add support for soft shutdown via sys-off APIJerome Neanne
Use new API for power-off mode support: Link: https://lwn.net/Articles/894511/ Link: https://lore.kernel.org/all/7hfseqa7l0.fsf@baylibre.com/ sys-off API allows support of shutdown handler and restart handler. Shutdown was not supported before that enhancement. This is required for platform that are not using PSCI. Test: - restart: # reboot Default is cold reset: # cat /sys/kernel/reboot/mode Switch boot mode to warm reset: # echo warm > /sys/kernel/reboot/mode - power-off: # halt Tested on AM62-LP-SK board.

2023-06-15mfd: tps65219: Add GPIO cell instanceJerome Neanne
TPS65219 PMIC GPIOs are exposed in a standard way: gpiodetect gpiochip0 [tps65219-gpio] (3 lines) tps65219-gpios is incorrect cell name (plural). Changed to tps65219-gpio (singular) Co-developed-by: Jonathan Cormier <jcormier@criticallink.com> Signed-off-by: Jonathan Cormier <jcormier@criticallink.com> Reviewed-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Jerome Neanne <jneanne@baylibre.com> Signed-off-by: Lee Jones <lee@kernel.org> Link: https://lore.kernel.org/r/20230511-tps65219-add-gpio-support-v5-2-ebb94281c854@baylibre.com
2023-06-15mfd: Switch i2c drivers back to use .probe()Uwe Kleine-König
After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

2022-12-07mfd: tps65219: Add driver for TI TPS65219 PMICJerome Neanne
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 <jneanne@baylibre.com> Signed-off-by: Markus Schneider-Pargmann <msp@baylibre.com> Signed-off-by: Lee Jones <lee@kernel.org> Link: https://lore.kernel.org/r/20221104152311.1098603-5-jneanne@baylibre.com
