Add the missing devices with their required regulators. The regulators are named after
their label in the vendor schematics[0].

v3:
- drop reg_usb_vbus, non-controllable and served only as vin-supply
- fixed regulator-vcc-4v0 typo
- fold addition of pmic regulator labels into the pmic patch
- eeprom is a GT24C02B, fixed commit message
- added reg_qspi_vcc1v833
- fixed uboot nor name offset
- add missing "reg_" prefix for reg_pcie_vcc_3v3
- drop pcie{1,2}'s vpcie3v3-supply, it's already specified on the root ports

v2:
- drop reg_vcc_5v0_sys as per "non-controllable" review comments on
  similar patches for other boards (kept the root reg_usb_vbus for though)
- add reg_vcc_4v0 instead as p1 vin?-supply, misread the schematics
- drop mpcie_vcc_3v3 and use pcie_vcc_3v3 for pcie2* too
  ("non-controllable" again)
- all of the above makes it consistent with other k1 boards

for the board's power infrastructure and voltage regulation support.

Enable the DWC3 USB 3.0 controller, its associated combo_phy (USB 3 PHY)
and usbphy2 (USB 2 PHY) on the MusePi Pro board.

The board uses a VLI VL817 hub, providing four ports.

Enable the two PCIe controllers along with their associated PHYs. They
are routed to the M.2 M-key connector and to the PCIe slot.

Allow serial output with the same uboot/opensbi settings so the
console works without providing a cmdline.

Andre,
 
 Thanks for pushing this new version, overall, this series looks good to me,
Although there are few quite trivial issues, which I could help to fix it while
applying, let's give community some time to test and review..

 P.S I haven't run it on musepi board, but trust you tested all functions..

Andre,
 
 Thanks for pushing this new version, overall, this series looks good to me,
Although there are few quite trivial issues, which I could help to fix it while
applying, let's give community some time to test and review..

 P.S I haven't run it on musepi board, but trust you tested all functions..

alright, and sorry, my git send-email flow is a bit rusty, didn't notice those issues...

I tested the added devices except nvme as I don't have one connected.
But I do have a pci card in there, which works just fine, so generally speaking pcie works and I'd assume/hope nvme would too ;)

alright, and sorry, my git send-email flow is a bit rusty, didn't notice those issues...

I tested the added devices except nvme as I don't have one connected.
But I do have a pci card in there, which works just fine, so generally speaking pcie works and I'd assume/hope nvme would too ;)

Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Medium] Regulator minimum voltage constraints are set too loosely on fixed board rails, risking hardware brownouts.

Author: Andre Heider <a.heider@gmail.com>

riscv: dts: spacemit: k1-musepi-pro: add PMIC and power infrastructure

This commit enables i2c8 and adds the connected SpacemiT P1 PMIC with its
related regulators for the board's power infrastructure and voltage
regulation support.

Should these minimum bounds be restricted to match the exact hardware layout
of the board?

The labels buck3_1v8 and buck4_3v3 indicate these rails are wired for fixed
1.8V and 3.3V usage, but the regulator-min-microvolt allows them to scale
down to 0.5V. Could this loose constraint risk hardware brownouts if a driver
attempts dynamic voltage scaling on these rails?

Since buck5 is used as the parent supply for the DLDOs (dldoin1-supply and
dldoin2-supply), could the wide 0.5V minimum constraint allow the OS to drop
its voltage below the necessary headroom needed to power the downstream
DLDOs?

riscv: dts: spacemit: k1-musepi-pro: enable QSPI and add SPI NOR

This commit adds the QSPI controller node and describes the attached SPI
NOR flash. It also adds a corresponding vendor flash partition layout.

Should these partition nodes use the generic partition@ naming convention
instead of specific functional names?

The device tree schema for fixed-partitions expects child nodes to match the
pattern ^partition@[0-9a-f]+$. Using specific names like bootinfo@0 might
trigger dtc and schema validation warnings.

Could these functional names be provided via the label property instead,
while keeping the node names generic?
