2024-12-01Get rid of 'remove_new' relic from platform driver structLinus Torvalds
The continual trickle of small conversion patches is grating on me, and is really not helping. Just get rid of the 'remove_new' member function, which is just an alias for the plain 'remove', and had a comment to that effect: /* * .remove_new() is a relic from a prototype conversion of .remove(). * New drivers are supposed to implement .remove(). Once all drivers are * converted to not use .remove_new any more, it will be dropped. */ This was just a tree-wide 'sed' script that replaced '.remove_new' with '.remove', with some care taken to turn a subsequent tab into two tabs to make things line up. I did do some minimal manual whitespace adjustment for places that used spaces to line things up. Then I just removed the old (sic) .remove_new member function, and this is the end result. No more unnecessary conversion noise. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2023-08-12misc: tps6594: Remove redundant dev_err_probe() for platform_get_irq_byname()Ruan Jinjie
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.

2023-08-04misc: tps6594-pfsm: Convert to platform remove callback returning voidUwe Kleine-König
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.

2023-06-15misc: tps6594-pfsm: Add driver for TI TPS6594 PFSMJulien Panis
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.
