i2c: Add a DM_I2C driver for the sun8i RSB controller

2021-10-12T09:19:18Z

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.

Convert CONFIG_SYS_I2C_LEGACY to Kconfig and add CONFIG_[ST]PL_SYS_I2C_LEGACY

2021-08-30T18:10:07Z

First, we convert CONFIG_SYS_I2C_LEGACY to Kconfig. Next, as you cannot have SYS_I2C_LEGACY and DM_I2C at the same time, introduce CONFIG_SPL_SYS_I2C_LEGACY so that we can enable the legacy option only in SPL. Finally, for some PowerPC cases we also need CONFIG_TPL_SYS_I2C_LEGACY support. Convert all of the existing users to one or more symbols. Signed-off-by: Tom Rini

i2c: Rename CONFIG_SYS_I2C to CONFIG_SYS_I2C_LEGACY

2021-07-28T18:29:37Z

It is quite confusing that CONFIG_SYS_I2C selects the legacy I2C and CONFIG_DM_I2C selects the current I2C. The deadline to migrate I2C is less than a year away. Also we want to have a CONFIG_I2C for U-Boot proper just like we have CONFIG_SPL_I2C for SPL, so we can simplify the Makefile rules. Rename this symbol so it is clear it is going away.
