[PATCH v2 0/5] arm64: dts: exynos: add initial support for Samsung Galaxy Watch FE

[Aiden Isik via B4 Relay]

Hi there,

This patchset adds initial support for the Exynos5515 SoC, along with
support for the Samsung Galaxy Watch FE (codenamed lucky7), which uses
this SoC.

Support for the following is added:
- Bootloader framebuffer
- Both CPU cores
- Memory
- Generic timer
- Watchdog timer
- CMU_TOP, CMU_FSYS, CMU_PERI clock management units
- ChipID

Currently, these device trees support booting the device to an initramfs.

There are quite a few regions of reserved memory, where usage of them
can crash the system and/or cause unexpected behaviour. Currently, most
of them are named "misc-rmem@addr". They will be given names as their
accompanying device drivers are added and their purpose becomes apparent.
If you would like them named feel differently, feel free to let me know.

The VGIC maintenance interrupt seems to be unavailable on this SoC.
I cannot find any reference to it, nor usage of it, anywhere.
It *could* very well still exist, but it is a mystery for now (and also
not a *huge* deal on a low-power SoC designed for smartwatches).

I am getting checkpatch warnings on this patchset advising to check
MAINTAINERS as new files were added, but I am ignoring them as the
entirety of arch/arm64/boot/dts/exynos is covered already.

This patchset depends on [1] for drivers and device tree bindings.
Note: This dependency was merged into the linux-watchdog tree.

Kind regards,
