+Subject: [PATCH 1/5] arm64: dts: rockchip: Add common definitions for NanoPi
+ R6C and R6S
+
+The FriendlyElec NanoPi R6C and R6S are quite similar boards,
+although they differ in:
+- M.2 M-Key connector vs second RTL8125BG Ethernet port
+- One of the LEDs has a different function on each board
+- 12-pin GPIO FPC vs 30-pin GPIO header
+- R6S has a PWM-based IR receiver while the R6C has not
+- R6S has a 5V fan connector while the R6C has not
+
+Refactor their DT files by adding a common definitions file to
+improve differentiation clarity between both boards and to make
+hardware-specific DT changes easier in the long run.
+Do not introduce any functional changes.

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