* misc: tps6594: Remove redundant dev_err_probe() for platform_get_irq_byname()Ruan Jinjie2023-08-121-2/+1
| | | | | | | | | | | There is no need to call the dev_err_probe() function directly to print a custom message when handling an error from platform_get_irq_byname() function as it is going to display an appropriate error message in case of a failure.

* misc: tps6594-pfsm: Convert to platform remove callback returning voidUwe Kleine-König2023-08-041-4/+2
| | | | | | | | | | | | | | | | | | The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() is renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

* misc: tps6594-pfsm: Add driver for TI TPS6594 PFSMJulien Panis2023-06-151-0/+306
This PFSM controls the operational modes of the PMIC: - STANDBY and LP_STANDBY, - ACTIVE state, - MCU_ONLY state, - RETENTION state, with or without DDR and/or GPIO retention. Depending on the current operational mode, some voltage domains remain energized while others can be off. This PFSM is also used to trigger a firmware update, and provides R/W access to device registers. See Documentation/misc-devices/tps6594-pfsm.rst for more information.
