Subject: [PATCH 04/14] mfd: arizona: Allow building arizona MFD-core as module
|
||
|
|
|
||
|
|
There is no reason why the arizona core,irq and codec model specific
|
||
|
|
regmap bits cannot be build as a module. All they do is export symbols
|
||
|
|
which are used by the arizona-spi and/or arizona-i2c modules, which
|
||
|
|
themselves can be built as module.
|
||
|
|
|
||
|
|
Change the Kconfig and Makefile arizona bits so that the arizona MFD-core
|
||
|
|
can be built as a module.
|
||
|
|
|
||
|
|
This is especially useful on x86 platforms with a WM5102 codec, this
|
||
|
|
allows the arizona MFD driver necessary for the WM5102 codec to be
|
||
|
|
enabled in generic distro-kernels without growing the base kernel-image
|
||
|
|
size.
