Hi,
this is the third revision of the Omnivision OV4689 driver. Main
changes in this version are (1) mapping physical camera gain to
monotonous and mostly linear logical gain exposed via corresponding
control and (2) reporting consistent pixel rate and hblank. These and
other minor changes are listed below:
changes in v3:
- set 1st patch title to: "media: dt-bindings: i2c: document OV4689"
- schema: drop clock-names
- driver: use dem_clk_get(NULL)
- schema: remove maxItems from powerdown-gpios
- schema: make gpios optional
- driver: use devm_gpiod_get_optional()
- driver: remove __ prefixes from function names
- driver: switch to .probe_new
- driver: remove of_match_ptr
- driver: add and use enum ov4689_mode_id
- driver: make xvclk optional & try to get frequency from ACPI
- driver: drop #if defined(CONFIG_MEDIA_CONTROLLER) in remove
- driver: use ARRAY_SIZE(ov4689_supply_names) instead of define
- driver: remove unused controls from struct ov4689
- driver: use 504000000 instead of OV4689_LINK_FREQ_500MHZ
- driver: compare link frequencies with menu array clock-frequency
- driver: replace |= with ret = ret ?:
- driver: merge power on/off into pm callbacks
- driver: use actual clock rate in ov4689_cal_delay
- driver: set up controls after writing register table in s_stream()
- driver: remap sensor gain to linear and monotonous logical gain
- driver: set pixel_rate to 480000000
- driver: set HTS so that we have 30.00 fps and fix HBLANK reporting
changes in v2:
- bindings: reword descriptions
- bindings: move clock description to clocks property
- bindings: add data-lanes and link-frequencies properties to port
- driver: validate media bus configuration when probing

+description: |
+ The Omnivision OV4689 is a high performance, 1/3-inch, 4 megapixel
+ image sensor. Ihis chip supports high frame rate speeds up to 90 fps
+ at 2688x1520 resolution. It is programmable through an I2C
+ interface, and sensor output is sent via 1/2/4 lane MIPI CSI-2
+ connection.

Gentle ping. Anything to do on my side to get [2/2] reviewed?
