Commit Message

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. Clock controller node (using stub driver for now)
5. Pinctrl nodes for GPIO
6. Serial node

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
