Subject: DM: I2C: Switch display5 board to use DM_I2C
X-Git-Tag: v2020.01-rc1~33^2~95
X-Git-Url: https://git.librecmc.org/?p=oweals%2Fu-boot.git;a=commitdiff_plain;h=dac9a8f8a2ae3a116748d056305251cfc035a6e4

DM: I2C: Switch display5 board to use DM_I2C

After this commit the display5 device would use I2C driver supporting
driver model (DM_I2C).

The 'i2c' and 'eeprom' commands now use DM I2C drivers and initialize
on-bus devices according to device tree description.
