Child domains can be deferred by the core because one of its resources
is not available yet, in such case, it will print an error, but
later it will succeed to probe. Fix that using the dev_err_probe()
function so it only prints an error on a real error.

rx_callback is a standard mailbox callback mechanism and could
cover the function of proprietary cmdq_task_cb, so it is better
to use the standard one instead of the proprietary one. But
register rx_callback should before mbox_request_channel(),

The mmsys driver supports only MT8173 device for now, but like other system
controllers is an important piece for other Mediatek devices. Actually
it depends on the mt8173 clock specific driver but that dependency is

a specific model, make the driver depends on the generic ARCH_MEDIATEK and
enable by default so other Mediatek devices can start using it without

In the actual implementation the same compatible string
"mediatek,<chip>-mmsys" is used to bind the clock drivers
(drivers/soc/mediatek) as well as to the gpu driver
(drivers/gpu/drm/mediatek/mtk_drm_drv.c). This ends with the problem
that the only probed driver is the clock driver and there is no display
at all.
In any case having the same compatible string for two drivers is not
correct and should be fixed. To fix this, and maintain backward
compatibility, we can consider that the mmsys driver is the top-level
entry point for the multimedia subsystem, so is not a pure clock
controller but a system controller, and the drm driver is instantiated
by that MMSYS driver.

create a new MMSYS platform driver in drivers/soc/mediatek that

"The rest of the overflow changes for v4.18-rc1.
This includes the explicit overflow fixes from Silvio, further
struct_size() conversions from Matthew, and a bug fix from Dan.
But the bulk of it is the treewide conversions to use either the
2-factor argument allocators (e.g. kmalloc(a * b, ...) into
kmalloc_array(a, b, ...) or the array_size() macros (e.g. vmalloc(a *
b) into vmalloc(array_size(a, b)).
Coccinelle was fighting me on several fronts, so I've done a bunch of

because the R8A77970 driver is missing a header file that came from

Multiple platforms would always use their own way handling CS timing
extension on the bus which leads to a little bit code duplication.
Therefore, the patch groups the similar logic to handle CS timing
extension into the common function which allows the following SoCs
have more reusability for configing CS timing.
