mfd: Add missing MODULE_DESCRIPTION() macros

2024-07-04T16:38:40+00:00

On x86, make allmodconfig && make W=1 C=1 reports:

 WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/mfd/arizona.o
 WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/mfd/pcf50633-gpio.o
 WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/mfd/timberdale.o
 WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/mfd/ssbi.o
 WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/mfd/rt4831.o
 WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/mfd/intel_soc_pmic_bxtwc.o

Add the missing invocation of the MODULE_DESCRIPTION() macro to all
files which have a MODULE_LICENSE().

This includes mfd-core.c and vexpress-sysreg.c which, although they
did not produce a warning with the x86 allmodconfig configuration, may
cause this warning with other configurations.

mfd: vexpress-sysreg: Fix resource compound literal assignments

2022-11-14T09:01:39+00:00

Since DEFINE_RES_*() macros were converted to provide a compound literal
the user doesn't need to repeat it. Moreover, it may not be compiled.

vexpress: Move setting master site to vexpress-config bus

2020-05-13T17:42:46+00:00

There's only a single caller of vexpress_config_set_master() from
vexpress-sysreg.c. Let's just make the registers needed available to
vexpress-config and move all the code there. The registers needed aren't
used anywhere else either. With this, we can get rid of the private API
between these 2 drivers.

mfd: vexpress-sysreg: Support building as a module

2020-05-13T17:42:45+00:00

Enable building the vexpress-sysreg driver as a module.

As deferred probe between the vexpress components works now, we don't
need to create struct devices early with of_platform_device_create().

mfd: vexpress-sysreg: Use devres API variants

2020-05-13T17:42:45+00:00

Use the managed devm_gpiochip_add_data() and devm_mfd_add_devices()
instead of their unmanaged counterparts. With this, no .remove() hook is
needed for driver unbind.

mfd: vexpress-sysreg: Drop unused syscon child devices

2020-05-13T17:42:45+00:00

The "sys_id", "sys_misc" and "sys_procid" devices don't have a user
anywhere in the tree and do nothing more than create a syscon regmap for
a single register or 2. That's an overkill for creating child devices.
Let's just remove them.

ARM: vexpress: Move vexpress_flags_set() into arch code

2020-05-05T16:42:39+00:00

vexpress_flags_set() is only used by the platform SMP related code and
has nothing to do with the vexpress-sysreg MFD driver other than both
access the same h/w block. It's also only needed for 32-bit systems and
must be built-in for them. Let's move vexpress_flags_set() closer to
where it is being used. This will allow for vexpress-sysreg to be built
as a module.

gpio: generic: factor into gpio_chip struct

2016-01-05T10:21:00+00:00

The separate struct bgpio_chip has been a pain to handle, both
by being confusingly similar in name to struct gpio_chip and
for being contained inside a struct so that struct gpio_chip
is contained in a struct contained in a struct, making several
steps of dereferencing necessary.

Make things simpler: include the fields directly into
, #ifdef:ed for CONFIG_GENERIC_GPIO, and
get rid of the  altogether. Prefix
some of the member variables with bgpio_* and add proper
kerneldoc while we're at it.

Modify all users to handle the change and use a struct
gpio_chip directly. And while we're at it: replace all
container_of() dereferencing by gpiochip_get_data() and
registering the gpio_chip with gpiochip_add_data().
