[PATCH v2 0/4] Quartz64-A fixes and enablement from 5.17-rc1

[Peter Geis]

Good Evening,

This is the first of several patch series for further expanding
Quartz64-A support.

This series has the following patches:
Fix the ddr regulator voltage.
Add pmu_io_domains to permit sdio and high speed emmc support.
Add sdmmc1 node for wifi support.
Annotate con40 functions and enable i2c3.

Please review and apply.

Very Respectfully,
Peter Geis

Changelog:
v2:
- drop status = "okay" from sdio_pwrseq
- drop disable-wp from sdmmc1
- move reset-gpios to be alphabetical in sdio_pwrseq
- add con40 annotation patch

[PATCH v2 1/4] arm64: dts: rockchip: fix Quartz64-A ddr regulator voltage

[Peter Geis]

The Quartz64 Model A uses a voltage divider to ensure ddr voltage is
within specification from the default regulator configuration.
Adjusting this voltage is detrimental, and currently causes the ddr
voltage to be about 0.8v.

Remove the min and max voltage setpoints for the ddr regulator.

Quartz64-A")

[PATCH v2 2/4] arm64: dts: rockchip: add Quartz64-A pmu_io_domains

[Peter Geis]

Several io power domains on the Quartz64-A operate at 1.8v.
Add the pmu_io_domains definition to enable support for this.
This permits the enablement of the following features:
sdio - wifi support
sdhci - mmc-hs200-1_8v

[PATCH v2 3/4] arm64: dts: rockchip: add Quartz64-A sdmmc1 node

[Peter Geis]

The sdmmc1 node on Quartz64-A supports the optional wifi module from
Pine64.
Add the sdmmc1 node and requisite sdio_pwrseq to enable wifi support on
the Quartz64-A.

[PATCH v2 4/4] arm64: dts: rockchip: add Quartz64-A con40 hardware

[Peter Geis]

The Quartz64-A has a 40 pin connector that exposes various functions.
Annotate the functions exposed in the device tree.
Enable i2c3, which is pulled up to vcc_3v3 on board.

The following functions are currently exposed:
i2c3
spi1
uart2
uart0
spdif
