i2c: muxes: Drop obsolete dependency on COMPILE_TEST

2022-08-22T22:15:01Z

Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), it is possible to test-build any driver which depends on OF on any architecture by explicitly selecting OF. Therefore depending on COMPILE_TEST as an alternative is no longer needed. It is actually better to always build such drivers with OF enabled, so that the test builds are closer to how each driver will actually be built on its intended target. Building them without OF may not test much as the compiler will optimize out potentially large parts of the code. In the worst case, this could even pop false positive warnings. Dropping COMPILE_TEST here improves the quality of our testing and avoids wasting time on non-existent issues. Signed-off-by: Jean Delvare Acked-by: Peter Rosin Signed-off-by: Wolfram Sang

i2c: i2c-mux-gpmux: new driver

2017-06-03T10:29:26Z

This is a general purpose i2c mux that uses a multiplexer controlled by the multiplexer subsystem to do the muxing. The user can select if the mux is to be mux-locked and parent-locked as described in Documentation/i2c/i2c-topology.
