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

[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.

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..
