This driver supports the I2C module on the Renesas RZ/G2L (R9A07G044) SoC, also known as the RIIC module. This patch is based on both the u-boot driver in the Renesas RZ BSP 3.0.5 release [1] (commit 7fcc1fdc2534), and the Linux v6.7 driver (commit 0dd3ee311255). Support for deblocking the I2C bus is included as this may be needed after triggering a reset via the Power Management IC (PMIC) over I2C (the PMIC asserts the reset line before the SoC completes the I2C write transaction with obvious bus locking effects). If the SDA line is observed to be low during initialisation, we automatically attempt to deblock.

Enable support for the Renesas RZ/G2L family of SoCs. Currently
|
|
support is only included for the RZ/G2L itself (based on the R9A07G044
|
|
SoC). Support for additional SoCs in this family (RZ/G2LC, RZ/G2UL,
|
|
RZ/V2L & RZ/Five) is not yet available.
