Sorry could you please help to explain the intention here? Note the
iProc I2C IP can be found in various iProc family of SoCs, but to my
best knowledge, there hasn't been any changes of the IP in any of those
SoCs.
Is the compatible ID "brcm,$mysoc-iproc-i2c" only to clarify that it's
for a specific SoC? If so, what should the compatible ID array look
like? Should it be changed to the following?
static const struct of_device_id bcm_iproc_i2c_of_match[] = {
{ .compatible = "brcm,iproc-i2c" },
{ .compatible = "brcm,$mysoc-iproc-i2c" },
{},
};
