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. [1] - https://lore.kernel.org/all/20260227111134.2163701-1-jan-kernel@kantert.net/ --- Changelog in v3 - Patch 7 - reworded the commit message to better describe i2c clock. - make clocks property available for all compatibles. - change "realtek,rtl9607-i2c" compatible to be under the same if statement as "realtek,rtl9310-i2c" for "realtek,scl". - Link to v2: https://lore.kernel.org/linux-i2c/20260319175753.32338-1-adilov@disroot.org/ Changelog in v2 - rebased on top of the patch from Jan Kantert. - Patch 7 (to my best understanding of Krzysztof's request): - added the "clocks: false" for compatibles that are not realtek,rtl9607-i2c. - Link to v1: https://lore.kernel.org/linux-i2c/20260314082628.25206-1-adilov@disroot.org/ --- Rustam Adilov (8): i2c: rtl9300: split data_reg into read and write reg i2c: rtl9300: introduce max length property to driver data i2c: rtl9300: introduce F_BUSY to the reg_fields struct i2c: rtl9300: introduce a property for 8 bit width reg address i2c: rtl9300: introduce clk struct for upcoming rtl9607 support i2c: rtl9300: intoduce new function properties to driver data dt-bindings: i2c: realtek,rtl9301-i2c: extend for RTL9607C support i2c: rtl9300: add RTL9607C i2c controller support .../bindings/i2c/realtek,rtl9301-i2c.yaml | 10 +- drivers/i2c/busses/i2c-rtl9300.c | 191 ++++++++++++++---- 2 files changed, 165 insertions(+), 36 deletions(-) -- 2.53.0
