i2c: Add Microchip PolarFire SoC I2C driver

2021-12-02T08:43:51Z

Add I2C driver code for the Microchip PolarFire SoC. This driver supports I2C data transfer and probe for I2C slave addresses. Signed-off-by: Padmarao Begari Reviewed-by: Leo Yu-Chi Liang

arm: mvebu: a3720: Create Kconfig option for I2C_MV

2021-10-21T05:39:05Z

Move the config option CONFIG_I2C_MV to a Kconfig option CONFIG_SYS_I2C_MV and move the default definition from config header files into defconfigs. Signed-off-by: Marek Behún Reviewed-by: Stefan Roese

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.

i2c: fsl_i2c: Migrate to Kconfig

2021-08-30T18:10:07Z

- As there are no boards that use different values for speed / slave on different buses, use a single option. - Switch to using the common SYS_I2C_SPEED / SYS_I2C_SLAVE options. - Introduce _HAS_ options for additional buses as only the first one is common to all users. - Convert all remaining symbols to Kconfig.

ti: i2c: Convert CONFIG_SYS_OMAP24_I2C to CONFIG_SYS_I2C namespace

2021-08-30T18:10:07Z

The omap24xx I2C driver uses its own CONFIG namespace for common I2C variables. Rather than convert more of them to Kconfig, rename these to the common I2C ones and remove the entirely unused functionality. As part of this, we make the am335x_shc platforms consistent with their intended speed values. Signed-off-by: Tom Rini
