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'.

Respond to v3 RESEND (this thread), or I may collect responses from
either thread they are the same content. I'd missed a linux-riscv list
CC line on a patch and that confused patchwork, and then I missed
'RESEND' in subject for the re-send series after the cover letter.
Patchwork sees the RESEND series now, and sorry for the added noise. -E

There is no memory controllers driver change, so I am fine if this goes
via SoC/DTS tree.  If you want me to pick it up, please ping on IRC.

Best regards,
Krzysztof

That's cool, I will take it with the dts changes. Thanks.

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

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'.

Don't send the same patch multiple times. To which one people should
respond?
