Define the GPIO connected to the PCA9564 using a GPIO lookup table. This will allow the i2c-pca-platform driver to use the device managed APIs to lookup the gpio instead of using platform_data. Signed-off-by: Chris Packham <chris.packham@alliedtelesis.co.nz> --- Changes in v2: - use correct API (gpio_add_lookup_table) and compile test. arch/sh/boards/board-sh7785lcr.c | 10 ++++++++++ 1 file changed, 10 insertions(+)
