[PATCH 00/28] media: atomisp: Further sensor rework + exotic features removal

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi All,

Here is another set of atomisp patches from yours truely.

This basically consists of 2 parts:

1.  Further sensor driver modernization to work towards using standard
    v4l2 sensor drivers instead of atomisp specific copies
1a. For some sensors some GPIOs have different polarity depending on
    which board they are on and the order in which GPIOs are listed in
    in the ACPI resources also is not consistent between boards.
    Fixing this without relying on per board DMI quirks requires parsing
    the results of a special Intel ACPI _DSM. Add a new
    v4l2_get_acpi_sensor_info() helper for this
1b. Convert the gc0310 driver to use ACPI runtime pm instead of relying
    on the direct PMIC poking from atomisp_gmin_platform

2.  Further work on removing various exotic features, specifically
    prep work + remove support for streaming from 2 sensors at once,
    as discussed here:
