[PATCH 00/25] ARM: rockchip: Add peripheral support for RV1106

[Vladislav Leonov]

Basic support for the Rockchip RV1106/RV1103 SoCs currently under review.
This series builds on top of that and enables the peripherals needed to
bring up a board beyond a serial console:

 - CRU reset controller support (dt-bindings + clk driver), needed
   by most of the other peripherals below.
 - Ethernet (GMAC) via dwmac-rk.
 - USB2 PHY and USB3-OTG (DWC3).
 - I2C (rk3x).
 - DMA (PL330) + support DMA for the UART nodes.
 - SPI, including a new SCLK_IN_SPI1 clock gate.
 - RNG.
 - SDMMC1.
 - A dts-only quirk (arm,cpu-registers-not-fw-configured) needed on
   the ARM timer node when booting without a secure firmware that
   pre-configures the CPU timer registers.
 - PWM.

Each new dt-binding is added ahead of the driver and dts nodes that
depend on it, so the series bisects cleanly.

This series depends on:
 - "Add support for the Rockchip RV1106 and RV1103" (v3)
   https://lore.kernel.org/all/20260729133609.3465563-1-sjg@chromium.org

 - "pinctrl: Add support for the Rockchip RV1106" (v3)
   https://lore.kernel.org/all/20260729132736.3807082-1-sjg@chromium.org

Testing: boot-tested on custom RV1106 board, with every peripheral
touched by this series: reset/CRU, Ethernet, USB2 PHY/USB3 DWC3,
I2C, DMA+UART, SPI, RNG, SDMMC1 and PWM - exercised and confirmed working.

[PATCH 09/25] dt-bindings: usb: rockchip,dwc3: add RV1106 SoC support

[Vladislav Leonov]

Document the DWC3 USB controller found on the Rockchip RV1106 SoC.

The RV1106 has a USB2-only (high-speed) OTG controller. Unlike the
other supported SoCs it has no dedicated suspend clock: it only needs
the 24 MHz reference clock, the AXI bus clock and the UTMI clock.

Since the top-level clock-names list enforces a fixed order with
"suspend_clk" as the second entry, relax the second and third entries
to enums so that the RV1106 clock set (ref_clk, bus_clk, utmi) can be
expressed, and add a per-SoC clause constraining RV1106 to exactly
these three clocks. The relaxation is required rather than cosmetic:
every other compatible's own clause already agrees with the shared
tuple position-by-position, but RV1106 genuinely reorders it (bus_clk
before utmi, no suspend_clk), and allOf branches are ANDed, so without
loosening the shared entries the two clauses would be unsatisfiable
together.

Don't expect maintainers to dig out patches for their subsystems
from a big series. This is not how upstream development works.
Repost 4+5 as a separate series to networking..
