They are somewhat different to the RTL9300 and RTL9310 but not enough to warrant a new whole driver. The patch series was split into patches that add/change something in the driver to smooth out the RTL9607C support addition in the end and for ease of review. Because of that, the patch 8 depends on all the prior patches before it. RTL9607C primarly uses the i2c controller for communication with laser driver over on i2c interface 1 or 2. I have successfully tested the byte read operations on my RTL9607C board which has GN25L95 laser driver in OpenWrt. This patch series now depends on the patch [1] from Jan Kantert.
