Cover letter [U-Boot] [PATCH 00/18] Exynos: move i2c driver to dm api

Hello all,

Quoted 35 lines · Przemyslaw Marczak

This patchset adds support to driver model i2c api for Exynos i2c driver. Few boards are using this driver, but the board peripherals are not ported to the new api yet. So this can't be enabled with the full board functionality.

In this case each Exynos5 based boards have fixed config dependencies Helloafor testing the dm i2c api with the new i2c driver. This will facilitate the peripheral porting.

For test, just enable CONFIG_DM_I2C in exynos5-common.h. The i2c command should work with this as previous.

This patchset also provides some changes related to Exynos4 boards. Most Exynos4 boards requires only pmic support, and this will be done with the new pmic framework soon.
