Re: [U-Boot] [PATCH 1/3] i2c: add support for offset overflow in to address

Hello Robert

Am 28.10.2019 um 18:44 schrieb Robert Beckett:

Some devices (2 wire eeproms for example) use some bits from the chip address to represent the high bits of the offset instead of or as well as using multiple bytes for the offset, effectively stealing chip addresses on the bus.

Add a chip offset mask that can be set for any i2c chip which gets filled with the offset overflow during offset setup.
