The patchset contains two patches: 1. Add DMI information of Lenovo X9 to the image upside-down list 2. Add Sony IMX471 image sensor driver The IMX471 driver can be found in the Intel ipu6-drivers repository [2]. To comply with the sensor driver implementation, the clean-up work includes: 1. Use CCI register helpers. 2. Enable and disable streams using enable_streams and disable_streams functions in struct v4l2_subdev_pad_ops. Invoke v4l2_subdev_s_stream_helper() to manage the streaming state. 3. Get rotation information from fwnode properties using v4l2_fwnode_device_parse(). 4. Finalizes the initialization of the subdev, including allocation of the active state using v4l2_subdev_init_finalize(). 5. Add the IMX471 driver to the Makefile and Kconfig file. 6. The mutex lock is managed by the V4l2 core. 7. Replace the supported link frequency with v4l2_link_freq_to_bitmap(). 8. Drop unused codes. [1] https://bugzilla.redhat.com/show_bug.cgi?id=2454119 [2] https://github.com/intel/ipu6-drivers/commits/master/drivers/media/i2c/imx471.c Changes in v4: 1. Add TBE20A0 (found on Lenovo X1 Carbon G14) to the supported sensors list. 2. Revert the sensor upside-down list to v1. 3. Decrease the max analog gain to 800 to mitigate the image flickering problem. 4. Return the error value when __v4l2_ctrl_modify_range() fails. 5. Fix indentation issue in Kconfig. 6. Fix the cci error value issue. 7. Drop unnecessary comments. 8. Drop unused link_freq control variable. Changes in v3: 1. Naming the register addresses and set up the value with the correct value length. 2. Implement the .get_selection(). 3. Drop "identified" field from struct imx471. 4. Drop "streaming" field from struct imx471 and use the __v4l2_ctrl_grab() instead. 5. Moreover, The naming for the register can be found in a seperated patch. If we agree with the patch, I will squash it into one patch. Changes in v2: 1. Change the Bayer format setting according to the vertical and horizontal flip settings. 2. Replace the self-owned mutex with the v4l2 subdev state. 3. Rework the flip control. 4. Manage the regulators using devm_regulator_bulk_get|disable|enbale API 5. Invoke devm_v4l2_sensor_clk_get to get clock-frequency Kate Hsuan (3): media: ipu-bridge: Add DMI information of Lenovo X9 to the image upside-down list media: ipu-bridge: Add Sony IMX471 for Lenovo X1 Carbon G14 media: i2c: imx471: Add Sony IMX471 image sensor driver MAINTAINERS | 6 + drivers/media/i2c/Kconfig | 10 + drivers/media/i2c/Makefile | 1 + drivers/media/i2c/imx471.c | 949 +++++++++++++++++++++++++++ drivers/media/pci/intel/ipu-bridge.c | 34 + 5 files changed, 1000 insertions(+) create mode 100644 drivers/media/i2c/imx471.c -- 2.54.0
