2017-06-27i2c: designware: add SLAVE mode functionsLuis Oliveira
- Changes in Kconfig to enable I2C_DESIGNWARE_SLAVE support - Slave functions added to core library file - Slave abort sources added to common source file - New driver: i2c-designware-slave added - Changes in the Makefile to compile the I2C_DESIGNWARE_SLAVE module when supported by the architecture. All the SLAVE flow is added but it is not enabled via platform driver.

2017-06-19i2c: designware: MASTER mode as separated driverLuis Oliveira
- The functions related to I2C master mode of operation were transformed in a single driver. - Common definitions were moved to i2c-designware-core.h - The i2c-designware-core is now only a library file, the functions associated are in a source file called i2c-designware-common and are used by both i2c-designware-master and i2c-designware-slave. - To decrease noise in namespace common i2c_dw_*() functions are now using ops to keep them private. - Designware PCI driver had to be changed to match the previous ops functions implementation. Almost all of the "core" source is now part of the "master" source. The difference is the functions used by both modes and they are in the "common" source file.
