This patchset adds the Sony IMX471 camera sensor driver to the Linux kernel and resolves the IPU7 camera can't work issueon Lenovo X9 laptops [1].
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.

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
