[PATCH 2/5] arm64: dts: rockchip: Fix regulators, gmac and naming on NanoPi R6C/R6S

Wed Jun 12 13:48:11 PDT 2024
Fix the alphabetical ordering in some nodes and rename some regulators
and pins to match the schematics [1][2] as well as to adhere to
preferred naming schemes.
In addition to that:
* vcc_3v3_sd_s0: Fix voltage to be 3.3V
* vcc3v3_pcie:
- Move to NanoPi R6C, this power switch is not available on R6S
- Fix vin-supply (is vcc_5v0 per schematics)
- Add gpios/pincrtl to enable power
* vcc5v0_usb: Remove this regulator since according to the schematics,
vcc5v0_host_20 and vcc5v0_usb_otg0 are directly powered by vcc_5v0
* gmac1: Add rx_delay of 0 (no delay since phy-mode = "rgmii-rxid")
* rgmii_phy1: Add phy-supply as seen in schematics
* pcie2*:
- Add pinctrl reset pins
- Update vpcie3v3-supply to match the schematics
* sdhci: Add vmmc-supply and vqmmc-supply

I didn't want to spam many patches with small fixes/improvements, so
this one patch includes lots of small changes. Let me know if another
method is preferred :)
