[PATCH] mfd: remove STA2x11 mfd driver
Posted by Lukas Bulwahn 11 months, 1 week ago 
From: Lukas Bulwahn <lukas.bulwahn@redhat.com>

With commit dcbb01fbb7ae ("x86/pci: Remove old STA2x11 support"), the mfd
driver for STA2x11 is not needed and cannot be built anymore.

Remove the driver and its header file.

Signed-off-by: Lukas Bulwahn <lukas.bulwahn@redhat.com>

You probably also saw the bits in drivers/media and drivers/ata
for sta2x11. I have another list of drviers that are (probably)
be unused for some reason. I have some more arm platforms that
I want to remove, and was planning to go through all of them
once the board support is gone, but feel free to take that list
below as a starting point case you are in a mood for destruction ;-)

Most of the drivers below lack DT support and were only used in
board files that have since been removed. Note that the s3c64xx
platform is still around and may use some of them even though we
had previously planned to drop the platform by now.
