"S3C2410 PM Suspend Memory CRC" feature (controlled by

With this I assume maintainership of the Integrator, Versatile
and RealView ARM reference machines.

It's no big secret that I've been maintaining them for years,
but might as well make it official so I get the mails and
don't miss anything.

I have also included some drivers that are closely associated
with the ARM reference designs and yet orphaned in the
MAINTAINERS file. I can surely maintain them too, or route
the question to the right people so it doesn't fall on the
floor of upward to the subsystem maintainers who have too much
to do already as it is.

Merge tag 'omap-for-v4.20/omap1-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/soc

A series of omap1 gpio changes for ams-delta

Janusz Krzysztofik has cleaned up ams-delta gpio usage along with
generic gpio framework improvments. This series contains the omap1
specific clean-up for ams-delta modem and unused gpios.

Note that this conflicts with the gpio-omap changes queued into
an immutable gpio branch ib-omap for the gpio-omap.h header file.
The merge resolution is to drop the IS_BUILTIN(CONFIG_GPIO_OMAP)
section and keep the #endif tagged for __ASSEMBLER__.

We need to maintain backwards compatibility with device trees that don't
define an enable method. At the same time we want the device tree to be
able to specify an enable-method and have it stick.

Previously by having smp assigned in the DT_MACHINE definition this
would be picked up by setup_arch() and override whatever
arm_dt_init_cpu_maps() had configured. Now we move the initial
assignment of default smp_ops to a dt_fixup and let
arm_dt_init_cpu_maps() override that if the device tree defines an
enable-method.
