region at an unused physical address on the boot CPU, or else your

platform code needs to implement mips_cdmm_phys_base() (see

bus: introduce an Marvell EBU MBus driver
The Marvell EBU SoCs have a configurable physical address space
layout: the physical ranges of memory used to address PCI(e)
interfaces, NOR flashes, SRAM and various other types of memory are
configurable by software, through a mechanism of so-called 'address
decoding windows'.
This new driver mvebu-mbus consolidates the existing code to address
the configuration of these memory ranges, which is spread into
mach-mvebu, mach-orion5x, mach-mv78xx0, mach-dove and mach-kirkwood.
Following patches convert each Marvell EBU SoC family to use this
driver, therefore removing the old code that was configuring the
address decoding windows.
It is worth mentioning that the MVEBU_MBUS Kconfig option is
intentionally added as a blind option. The new driver implements and
exports the mv_mbus_dram_info() function, which is used by various
Marvell drivers throughout the tree to get access to window
configuration parameters that they require. This function is also
implemented in arch/arm/plat-orion/addr-map.c, which ultimately gets
removed at the end of this patch series. So, in order to preserve
bisectability, we want to ensure that *either* this new driver, *or*
the legacy code in plat-orion/addr-map.c gets compiled in.
By making MVEBU_MBUS a blind option, we are sure that only a platform
that does 'select MVEBU_MBUS' will get this new driver compiled
in. Therefore, throughout the next patches that convert the Marvell
sub-architectures one after the other to this new driver, we add the
'select MVEBU_MBUS' and also ensure to remove plat-orion/addr-map.c
from the build for this specific sub-architecture. This ensures that
bisectability is preserved.
Ealier versions of this driver had a DT binding, but since those were
not yet agreed upon, they were removed. The driver still uses
of_device_id to find the SoC specific details according to the string
passed to mvebu_mbus_init(). The plan is to re-introduce a proper DT
binding as a followup set of patches.

mfd: vexpress: Convert custom func API to regmap
Components of the Versatile Express platform (configuration
microcontrollers on motherboard and daughterboards in particular)
talk to each other over a custom configuration bus. They
provide miscellaneous functions (from clock generator control
to energy sensors) which are represented as platform devices
(and Device Tree nodes). The transactions on the bus can
be generated by different "bridges" in the system, some
of which are universal for the whole platform (for the price
of high transfer latencies), others restricted to a subsystem
(but much faster).
Until now drivers for such functions were using custom "func"
API, which is being replaced in this patch by regmap calls.
This required:
* a rework (and move to drivers/bus directory, as suggested
by Samuel and Arnd) of the config bus core, which is much
simpler now and uses device model infrastructure (class)
to keep track of the bridges; non-DT case (soon to be
retired anyway) is simply covered by a special device
registration function
* the new config-bus driver also takes over device population,
so there is no need for special matching table for
of_platform_populate nor "simple-bus" hack in the arm64
model dtsi file (relevant bindings documentation has
been updated); this allows all the vexpress devices
fit into normal device model, making it possible
to remove plenty of early inits and other hacks in
the near future
* adaptation of the syscfg bridge implementation in the
sysreg driver, again making it much simpler; there is
a special case of the "energy" function spanning two
registers, where they should be both defined in the tree
now, but backward compatibility is maintained in the code
* modification of the relevant drivers:
* hwmon - just a straight-forward API change
* power/reset driver - API change
* regulator - API change plus error handling
simplification
* osc clock driver - this one required larger rework
in order to turn in into a standard platform driver
