sh: sh7785lcr: add GPIO lookup table for i2c controller reset (df0d3234) · Commits · 戴 / test

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:
