Link to v5: https://lore.kernel.org/linux-iio/SN7PR12MB8101B6D0AB1246797C67E25BA4CE2@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx/ Changes in v5: - I have addressed all the issues mentioned in the email responses. Additionally, regarding the IIO-related header files, I have checked and found no unused headers. - Link to v4: https://lore.kernel.org/linux-iio/SN7PR12MB810129D8180B1C9593A8E078A4FB2@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx/ Changes in v4: - Removed hardware-irrelevant properties from dt-bindings, retaining only channel configuration related `channel-positive` and `channel-negative`. Grouped by channel. Retained `channel-in-use` as it is hardware-related. - Removed redundant register definitions. - Reorganized `struct hx9023s_data`, extracting channel-related attributes into a new `struct hx9023s_ch_data`. - Optimized bit operation related code. - Replaced `of_` versions with generic firmware parsing functions. - Fixed other issues mentioned in the email feedback. - Link to v3: https://lore.kernel.org/linux-iio/20240602152638.2c674930@jic23-huawei/ --- Yasin Lee (3): dt-bindings: vendor-prefixes: add tyhx dt-bindings: iio: proximity: Add TYHX HX9023S iio: proximity: Add driver support for TYHX's HX9023S capacitive proximity sensor .../bindings/iio/proximity/tyhx,hx9023s.yaml | 93 ++ .../devicetree/bindings/vendor-prefixes.yaml | 2 + drivers/iio/proximity/Kconfig | 14 + drivers/iio/proximity/Makefile | 1 + drivers/iio/proximity/hx9023s.c | 1131 ++++++++++++++++++++ 5 files changed, 1241 insertions(+) --- base-commit: 1231e065edd236295c31904fe760117551608efa change-id: 20240616-add-tyhx-hx9023s-sensor-driver-e7dbe3bfe596 Best regards, -- Yasin Lee <yasin.lee.x@xxxxxxxxx>
