Re: [U-Boot] [PATCH v4 1/2] i2c:soft:multi: Support for multiple soft I2C buses at Samsung boards

Hi Minkyu,

Support for multiple soft I2C buses.

Multibus I2C support is achieved by defining get_multi_{sda|scl}_pin functions to switch between multiple "soft" I2C buses.

Common definition of I2C_X I2C buses is provided at <i2c.h>.

Changes for v2:

• Common Samsung code has been put to

board/samsung/common/multi_i2c.c file

• I2C_{4|5} have been renamed to I2C_{0|1}
• *soft_i2c_name[] table has been removed

Changes for v3:

• None

Changes for v4:

• Common definitions of available I2C buses are now defined at <i2c.h>
• Compatibility layer (I2C_0) has been added temporarily to not break

the Trats I2C communication with PMIC. It will be removed when redesigned PMIC will be posted
