Bring in additional downstream U-Boot boot loader changes for StarFive
VisionFive2 board target (and related JH7110 common boards). Create a
basic dt-binding (and not any Linux driver) in support of the
memory-controller dts node used in mainline U-Boot. Also add
bootph-pre-ram hinting to jh7110.dtsi needed at SPL boot phase.
Changes since v2:
- patch 1/3 "add StarFive JH7110 SoC DMC": wrap at 80 col, clock-names
const is 'pll'.
- patch 2/3 "add memory controller node": memory-controller node follows
sorting style by reg address, between watchdog and crypto nodes. Update
clock-names to 'pll'.
- patch 3/3 "bootph-pre-ram hinting needed by boot loader": add missing
hints for syscrg dependencies 'gmac1_rgmii_rxin', 'gmac1_rmii_refin',
and 'pllclk'.
E Shattow (3):
dt-bindings: memory-controllers: add StarFive JH7110 SoC DMC
riscv: dts: starfive: jh7110: add DMC memory controller
riscv: dts: starfive: jh7110: bootph-pre-ram hinting needed by boot

Add bootph-pre-ram hinting to jh7110.dtsi:
- CPU interrupt controller(s)
- gmac1_rgmii_rxin fixed-clock (dependency of syscrg)
- gmac1_rmii_refin fixed-clock (dependency of syscrg)
- oscillator
- core local interrupt timer
- syscrg clock-controller
- pllclk clock-controller (dependency of syscrg)
- DDR memory controller
