mfd: core: Un-constify mfd_cell.of_reg

2023-11-20T10:59:23+00:00

[ Upstream commit 3c70342f1f0045dc827bb2f02d814ce31e0e0d05 ] Enable dynamically filling in the whole mfd_cell structure. All other fields already allow that.

mfd: core: Remove .enable() and .disable() callbacks

2023-04-26T10:40:29+00:00

With commit dd77f5fa97d3 ("mfd: Remove toshiba tmio drivers") the last mfd driver that implements these callbacks is gone and since commit 652719b1003a ("w1: remove ds1wm driver") the last user is gone. The corresponding functions mfd_cell_enable() and mfd_cell_disable() are also unused (since commit 0ca222c81977 ("leds: Remove asic3 driver")).

mfd: core: Reorder fields in 'struct mfd_cell' to save some memory

2023-04-26T10:40:27+00:00

Group some variables based on their sizes to reduce hole and avoid padding. On x86_64, this shrinks the size from 144 to 128 bytes. As an example: $ size drivers/mfd/as3722.o (Before) text data bss dec hex filename 9441 680 16 10137 2799 drivers/mfd/as3722.o $ size drivers/mfd/as3722.o (After) text data bss dec hex filename 9345 680 16 10041 2739 drivers/mfd/as3722.o Signed-off-by: Christophe JAILLET Signed-off-by: Lee Jones Link: https://lore.kernel.org/r/bb631974888dfe1af593b6280cf30fb913d2d1a4.1676365116.git.christophe.jaillet@wanadoo.fr

mfd: mfd-core: Add mechanism for removal of a subset of children

2020-08-13T06:50:50+00:00

Currently, the only way to remove MFD children is with a call to mfd_remove_devices, which will remove all the children. Under some circumstances it is useful to remove only a subset of the child devices. For example if some additional clean up is required between removal of certain child devices. To accomplish this a level field is added to mfd_cell, the normal mfd_remove_devices is modified to not remove devices that are set to a higher level and a corresponding mfd_remove_devices_late function is added to remove those children.
