Subject: boards: ls2088a: Add support of I2C driver model.
X-Git-Tag: v2019.10-rc3~7^2~24
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=654e4e70d4ab0219f68ed6a540faa07a9f476866;p=platform%2Fkernel%2Fu-boot.git

boards: ls2088a: Add support of I2C driver model.

DM_I2C_COMPAT is a compatibility layer that allows using the non-DM
I2C API when DM_I2C is used.When DM_I2C_COMPAT is not enabled for
compilation, a compilation error will be generated. This patch
solves the problem that the i2c-related api of the ls2088a platform
does not support dm.
