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
