mfd: remove toshiba tmio drivers

2023-02-01T16:23:38+00:00

Four separate mfd drivers are in the "tmio" family, and all of them were used in now-removed PXA machines (eseries, tosa, and hx4700), so the mfd drivers and all its children can be removed as well.

mfd: t7l66xb: Remove #ifdef guards for PM related functions

2022-12-07T13:28:12+00:00

Use the new pm_sleep_ptr() macro to handle the .suspend/.resume callbacks. This macro allow the suspend and resume functions to be automatically dropped by the compiler when CONFIG_SUSPEND is disabled, without having to use #ifdef guards. This has the advantage of always compiling these functions in, independently of any Kconfig option. Thanks to that, bugs and other regressions are subsequently easier to catch.

mfd: t7l66xb: Drop platform disable callback

2022-07-19T09:54:38+00:00

None of the in-tree instantiations of struct t7l66xb_platform_data provides a disable callback. So better don't dereference this function pointer unconditionally. As there is no user, drop it completely instead of calling it conditional. This is a preparation for making platform remove callbacks return void.

mfd: t7l66xb: Make use of raw_spinlock variants

2017-04-27T08:25:05+00:00

The t7l66xb mfd driver currently implements an irq_chip for handling interrupts; due to how irq_chip handling is done, it's necessary for the irq_chip methods to be invoked from hardirq context, even on a a real-time kernel. Because the spinlock_t type becomes a "sleeping" spinlock w/ RT kernels, it is not suitable to be used with irq_chips. A quick audit of the operations under the lock reveal that they do only minimal, bounded work, and are therefore safe to do under a raw spinlock.

genirq: Remove irq argument from irq flow handlers

2015-09-16T13:47:51+00:00

Most interrupt flow handlers do not use the irq argument. Those few which use it can retrieve the irq number from the irq descriptor. Remove the argument. Search and replace was done with coccinelle and some extra helper scripts around it. Thanks to Julia for her help! Signed-off-by: Thomas Gleixner Cc: Julia Lawall Cc: Jiang Liu

mfd: Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc

2015-08-11T14:09:06+00:00

Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc while we already have a pointer to corresponding irq_desc. Do the same change to avoid the pattern "irq_get_chip_data(data->irq)". Signed-off-by: Jiang Liu Signed-off-by: Thomas Gleixner Signed-off-by: Lee Jones
