backlight: pcf50633-backlight: Remove unused driverThe pcf50633 was used as part of the OpenMoko devices butthe support for its main chip was recently removed in:commit 61b7f8920b17 ("ARM: s3c: remove all s3c24xx support")See https://lore.kernel.org/all/Z8z236h4B5A6Ki3D@gallifrey/Remove it.Signed-off-by: "Dr. David Alan Gilbert" Link: https://lore.kernel.org/r/20250311014959.743322-8-linux@treblig.orgSigned-off-by: Lee Jones List of files: /linux-6.15/include/linux/mfd/pcf50633/core.h

245cb473 - mfd: pcf50633: Remove #ifdef guards for PM related functions

Sun, 23 Oct 2022 09:48:30 +0000

mfd: pcf50633: Remove #ifdef guards for PM related functionsUse the new EXPORT_GPL_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr() macrosto handle the .suspend/.resume callbacks.These macros allow the suspend and resume functions to be automaticallydropped by the compiler when CONFIG_SUSPEND is disabled, without havingto use #ifdef guards.This has the advantage of always compiling these functions in,independently of any Kconfig option. Thanks to that, bugs and otherregressions are subsequently easier to catch.Signed-off-by: Paul Cercueil Signed-off-by: Lee Jones List of files: /linux-6.15/include/linux/mfd/pcf50633/core.h

68d641ef - mfd: Fix memleak in pcf50633_client_dev_register

Tue, 13 Oct 2009 22:12:33 +0000

mfd: Fix memleak in pcf50633_client_dev_registerSince platform_device_add_data copies the passed data, the allocatedsubdev_pdata is never freed. A simple fix would be to either free subdev_pdataor put it onto the stack. But since the pcf50633 child devices can rely onbeeing children of the pcf50633 core device it's much more elegant to get accessto pcf50633 core structure through that link. This allows to get completly ridof pcf5033_subdev_pdata.Signed-off-by: Lars-Peter Clausen Signed-off-by: Paul Fertser Signed-off-by: Samuel Ortiz List of files: /linux-6.15/include/linux/mfd/pcf50633/core.h

e98c73a2 - pcf50633: Get rid of charging restart software auto-triggering

Wed, 04 Nov 2009 21:24:57 +0000

pcf50633: Get rid of charging restart software auto-triggeringAfter reaching Battery Full condition MBC state machine switches backinto charging mode when the battery voltage falls below 96% of abattery float voltage. The voltage drop in Li-Ion batteries ismarginal (1-2%) till about 80% of its capacity - which means, after aBATFULL, charging won't be restarted until 75-80%.That is a desired behaviour recommended by battery manufacturers,don't mess with it.Signed-off-by: Paul Fertser Signed-off-by: Anton Vorontsov List of files: /linux-6.15/include/linux/mfd/pcf50633/core.h

31b4ff06 - pcf50633: introduces battery charging current control

Wed, 04 Nov 2009 21:24:55 +0000

pcf50633: introduces battery charging current controlImplement a new sysfs attribute to allow changing MBC charging limit onthe fly independently of usb current limit. It also gets setautomatically every time usb current limit is changed.Limiting charging current also prevents violating USB specification inthe case when the whole device is shut down and usb current limit isreset to the factory default by the pcf50633 state transition.Signed-off-by: Balaji Rao Signed-off-by: Paul Fertser Signed-off-by: Anton Vorontsov List of files: /linux-6.15/include/linux/mfd/pcf50633/core.h

ed52e62e - mfd: use a dedicated workqueue for pcf50633 irq processing

Mon, 27 Jul 2009 20:41:15 +0000

mfd: use a dedicated workqueue for pcf50633 irq processingUsing the default kernel "events" workqueue causes problems withsynchronous adc readings if initiated from some task on the sameworkqueue.I had a deadlock trying to use pcf50633_adc_sync_read from apower_supply class driver because the reading was initiated from theworkqueue and it waited for the irq processing to complete (to get theresult) and that was put on the same workqueue.Signed-off-by: Paul Fertser Signed-off-by: Samuel Ortiz List of files: /linux-6.15/include/linux/mfd/pcf50633/core.h

pcf50633_charger: Enable periodic charging restartThe battery charger state machine switches into charging mode whenthe battery voltage falls below 96% of a battery float voltage. Butthe voltage drop in Li-ion batteries is marginal(1~2 %) till about80% of its capacity - which means, after a BATFULL, charging won'tbe restarted until 80%.This work_struct function restarts charging at regular intervals tomake sure the battery doesn't discharge too much.Signed-off-by: Balaji Rao Cc: Andy Green Signed-off-by: Anton Vorontsov List of files: /linux-6.15/include/linux/mfd/pcf50633/core.h
