Re: [PATCH v8 0/8] i2c-octeon and i2c-thunderx driver

[Jan Glauber <jan.glauber@caviumnetworks.com>]

Hi Wolfram,

we want to add ACPI support to the ThunderX i2c driver
because it is meant for servers and some distributions
require ACPI there. The changes are small but I'll post
a new version of the remaining patches shortly.

Thanks,
Jan
