This driver allows I2C routing controlled through CPLD select registers on a wide range of Mellanox systems (CPLD Lattice device). MUX selection is provided by digital and analog HW. Analog part is not under SW control. Digital part is under CPLD control (channel selection/de-selection). Connectivity schema. .---. .-------------. | l | | |-- i2cx1 -- i2cx8 | i |-- i2cn --+--| mlxcpld mux | | n | | | |-- i2cy1 -- i2cy8 | u | | '-------------' | x | | | '---' '---------' i2c-mux-mlxpcld does not necessarily require i2c-mlxcpld. It can be used along with another bus driver, and still control i2c routing through CPLD mux selection, in case the system is equipped with CPLD capable of mux selection control. The Kconfig currently controlling compilation of this code is: drivers/i2c/muxes/Kconfig:config I2C_MUX_MLXCPLD Signed-off-by: Michael Shych <michaelsh@mellanox.com> Signed-off-by: Vadim Pasternak <vadimp@mellanox.com> Reviewed-by: Jiri Pirko <jiri@mellanox.com> Acked-by: Peter Rosin <peda@axentia.se> Signed-off-by: Wolfram Sang <wsa@the-dreams.de> |
