    [PATCH] I2C: algorithm and bus driver for PCA9564 · 8c30a9fa
    Ian Campbell authored
    Attached is a driver for the PCA9564 "Parallel to I2C" chip, it is
    similar in principle to the PCF8584 which is supported by the
    i2c-algo-pcf and i2c-elektor code, however it's not code compatible in
    any way: http://www.semiconductors.philips.com/pip/PCA9564PW.html
    
    The patch contains the PCA algorithm driver and a bus driver for an ISA
    card. It only supports master send and receive but I'm not sure that the
    Linux i2c stack supports client side operation anyhow, and I have no
    hardware to test on.
    
    It was tested on a PC104 card containing the PCA chip and an Atmel TPM
    device and also on a separate PC104 card with a DS1307 RTC hotwired onto
    it for testing purposes.
    
    The driver is against a 2.6 BK tree pulled on Friday. I also have a
    fairly trivial 2.4 backport if that is of interest.
