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

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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
