2021-10-12i2c: Add a DM_I2C driver for the sun8i RSB controllerSamuel Holland
This bus controller is used to communicate with an X-Powers AXP PMIC. Currently, various drivers access PMIC registers through a platform- specific non-DM "pmic_bus" interface, which depends on the legacy I2C framework. In order to convert those drivers to use DM_PMIC, this bus needs a DM_I2C driver. Refactor the rsb functions to take the base address as a parameter, and implement both the existing interface (which is still needed in SPL) and the DM_I2C interface on top of them. The register for switching between I2C/P2WI/RSB mode is the same across all PMIC variants, so move that to the common header. There are only a couple of pairs of hardware/runtime addresses used across all PMIC variants. So far the code expected only the "primary" pair, but some PMICs like the AXP305 and AXP805 use the secondary pair, so add support for that to the DM driver as well.

Today all the I2C instance point on the same global variable stm32_i2c_setup according the compatible: i2c_priv->setup = pointer to the same driver data. This patch changes this driver data (stm32f7_setup and stm32mp15_setup) to a const struct and move the timing struct 'setup' as element of i2c privdata, initialized in stm32_ofdata_to_platdata() with the driver configuration data.

2021-07-28i2c: Create a new Kconfig for I2CSimon Glass
At present we have CONFIG_SPL_I2C but not CONFIG_I2C. The reason CONFIG_I2C is not strictly necessary is that: a) We have CONFIG_SYS_I2C_LEGACY and CONFIG_DM_I2C for the two possible i2c stacks b) In U-Boot proper, we always build drivers/i2c/ regardless of the options Still, it is better to have CONFIG_I2C - it makes U-Boot proper similar to SPL/TPL, so we can (in a future commit) simplify the Makefile rules. Enable it by default, since as above, we have separate options (SYS_I2C_LEGACY and DM_I2C) to control whether it is 'really' enabled. Once we have migrated I2C to driver model, we can drop SYS_I2C_LEGACY and make DM_I2C become I2C. For now, this lets us simplify the Makefile rules.
