Samsung Exynos850 is ARMv8-based mobile-oriented SoC.
This patch adds minimal SoC support by including next Device Tree nodes:
1. Octa cores (Cortex-A55), supporting PSCI v1.0
2. ARM architecture timer (armv8-timer)
3. Interrupt controller (GIC-400)
4. Pinctrl nodes for GPIO
5. Serial node

Changes in v3:
- Used generic fixed clock for serial
Changes in v2:
* Commit message:
- Documented added dts features instead of CPU features
* exynos850-usi.dtsi:
- Removed, moved everything to exynos850.dtsi
* exynos850.dtsi:
- Root node:
- Added comment about engineering name (Exynos3830)
- Renamed pinctrl nodes, adding domain names
- Used hard coded IRQ numbers instead of named constants everywhere
- Added soc node, moved next nodes there: gic, clock, pinctrls and
serial
- Used address-cells=1 for soc node and removed unneeded 0x0 from
reg properties
- Moved exynos850-pinctrl.dtsi include line to the end of
exynos850.dtsi
- Coding style fixes
- cpus:
- Used address-cells=1 for cpus node
- Renamed cpu@0001 to cpu@1, and so on
- Left only "arm,cortex-a55" for cpus compatible
- Renamed reg = <0x0001> to <0x1> for cpus
- armv8 timer:
- Add comment about missing HV timer IRQ to armv8 timer node
- Removed not existing properties from armv8 timer node
- Fixed cpu number in CPU_MASK()
- Removed obsolete clock-frequency property
- GIC:
- Fixed GIC type to be GIC-400
- Fixed size of GIC's 2nd region to be 0x2000
- serial node:
- Hard coded clock number for serial_0 for now; will replace with
named const once proper clock driver is implemented
- Removed gate_uart_clk0 clock from serial_0, as that clock is not
supported in serial driver anyway (yet)
- clock node:
- Fixed clock controller node name (@0x12.. -> @12..)
* exynos850-pinctrl.dtsi:
- Referenced pinctrl nodes instead of defining those again in root node
- Fixed interrupt-cells (3 -> 2)
- Fixed USI related comments for pin config nodes
- Removed decon_f_te_* and fm_lna_en nodes (won't be used)
- Reordered pin config nodes by pin numbers
- Improved all comments
- Used existing named constants for pin-function and pin-pud
- Fixed node names (used hyphens instead of underscore)
- Fixed warnings found in W=1 build
