Hello Linus,
These 3 patches provide support for the Pseudo ISA adapter (i2c-isa), the VIA 686A Integrated Hardware Monitor (via686a) and Winbond W8378x series (w83781d) sensors. Both sensors depend on i2c-isa. The added files are modified versions of the ones found in the lm_sensors-2.7.0 package and were ported by me with help from Christoph Hellwig to the new driver model.
This patch (1/3) adds /drivers/i2c/busses/i2c-isa.c and adds it to Kconfig and Makefile in the same dir. Please apply.
Thanks,
GertJan
