This patch series introduces support for
the PERIC0 and PERIC1 blocks in the Exynos 990 SoC.
It includes devicetree bindings, clock definitions,
and driver support for the following components:
- Universal Serial Interface (USI):
- Adds samsung,exynos990-usi compatible
for defining USI nodes in PERIC0/1.
- Supports UART, SPI, and I2C modes.
- Defines all 18 USI nodes in the Exynos 990 device tree.
- SPI (Serial Peripheral Interface):
- Adds `samsung,exynos990-spi` compatible.
- Implements SPI port configuration data.
- Some controllers (SPI 8, 9, and 10) use a 256 bytes FIFO depth
instead of the usual 64 bytes.
- HSI2C (High-Speed I2C):
- Adds `samsung,exynos990-hsi2c` compatible for Exynos 990.
- Clock Management Unit (CMU) for PERIC0/1:
- Adds clock definitions for USI and I2C peripherals.
- CMU_PERIC0/1 clocks are not marked as critical.
This has been tested on the Samsung Galaxy S20 FE (r8s),
where USI and SPI interfaces are confirmed to be functional.
