[PATCH v6 0/3] Add DTS for SDM845 SoC and MTP

[PATCH v6 0/3] Add DTS for SDM845 SoC and MTP

[Rajendra Nayak]

These are basic device tree files needed to boot a SDM845 MTP
board to a ramfs based serial console shell

Bindings are based on whats proposed for pinctrl/serial/clock
drivers for SDM845 SoC
pinctrl: https://patchwork.kernel.org/patch/10157143/ (This is now pulled
in by Linus Walleij for 4.17)
clocks: https://lkml.org/lkml/2018/1/31/209 (under review)

I have dropped the patch that adds the serial/geni nodes from v6, as that
will be reposted along with the geni patch series by Karthik

Since 'PATCH 3/3' also adds an ITS node and keeps it disabled, we also depend
on https://lkml.org/lkml/2018/1/29/383

Andy, since we aren't adding anything new for clocks (gcc) and pinctrl,
do these look good to be pulled in for 4.17?

changes in v6:
* added the missing power-domain-cells property for gcc as reported
by Doug Anderson 
* Dropped the patch which added geni/serial nodes in dts. Karthik has
agreed to carry that patch along with his GENI series. 

changes in v5:
* Removed all instances of IRQ_TYPE_NONE

changes in v4:
* pull config changes to uart pins
* License in device tree files is still GPL-2.0

changes in v3:
* split the pinmux/pinconf nodes across SoC/Board files
* Fixes for issues reported with 'make dtbs W=2'
* other minor fixes based on review
 
changes in v2:
* dropped cpu-map
* dropped GIC_CPU_MASK_SIMPLE()
* Added new cpu compatible for kryo385
* added ITS node, marked as disabled

You shouldn't need redistributor-stride here, unless your GIC
implementation is not compliant with the architecture (i.e. really
buggy). I only know of one such implementation, and I'd rather you
remove this property unless your GIC is indeed non-compliant. If that's
the case, you should also document it.
