Subject: [PATCH v2 00/15] arm64: dts: meson: a1: introduce several peripheral IPs

This patch series introduces device tree declarations for various
peripheral IPs of the A1 SoC family, including clock controllers, EFUSE,
USB, SPI Flash Controller, SDIO, and UART_AO:
    - CLK: A1 SoC has four types on the board, namely PLL, Peripherals,
      CPU, and Audio, but only Amlogic A1 PLL and Peripherals clock
      controllers are currently supported.
    - EFUSE: consists of a 4k bit One Time Programmable (OTP) memory
      divided into 32 128-bit blocks, and data is accessed using the APB
      bus through software or the Key-ladder integrated with the EFUSE
      block.
    - USB: only one USB 2.0 high-speed port is available in the A1 SoC,
      supporting both HOST and DEVICE modes for OTG.
    - SPI Flash Controller: 4-bit QPI/SPI NOR Flash or NAND FLASH
      controller.
    - SDIO: for WiFi/IEEE802.11 connection.
    - UART_AO: for Bluetooth connection.
    - HWRNG: hardware random generator integrated into SoC.
    - AO SECURE: board info registers.

The above peripherals are integrated to new AD402 board device tree.

Changes v2 since v1 at [1]:
    - reorder meson-a1 dtsi includes to keep them sorted
    - remove extra empty lines
    - purge the unnecessary 'okay' status
    - reorder all device tree nodes (existing and new) sorted by 'reg'
      values
    - introduce new saradc definition
    - add hwrng dts node
    - provide ao secure dts node with board info registers
    - include all changes to new AD402 board device tree
    - add AD402 board to bindings
