hi,

This series adds support for the SK Hynix Hi-846 CMOS images sensor.
It includes the dt-bindings and the driver.

best wishes,

                              martin

revision history
----------------
v9: (thank you Pavel and Sakari)
* fix the probe() error paths (that I broke in v8)
* cheanups

v8: (thank you Laurent)
* add fwnode properties support for orientation and rotation on the board
* remove the arm64 defconfig addition patch. deal with that later.
* https://lore.kernel.org/linux-media/20210831134344.1673318-1-martin.kepplinger@puri.sm/

v7: (thank you Sakari)
* move the check for supported nr_lanes for a mode to set_format()
* change get_selection() according to the Sakaris' review
* check for the mipi link frequencies from DT
* check for the external clock rate and add assigned-clock-rates requirement
* https://lore.kernel.org/linux-media/20210712084137.3779628-1-martin.kepplinger@puri.sm/

v6:
* better digital gain defaults
* lane config fix found by smatch
* fix regulator usage in power_on()
* https://lore.kernel.org/linux-media/20210628101054.828579-1-martin.kepplinger@puri.sm/

v5: (thank you Laurent and Rob)
* minor dt-bindings fixes
* driver: disable lens shading correcting (no seed values yet used from "otp" for that)
* add reviewed-tags
* https://lore.kernel.org/linux-media/20210611101404.2553818-1-martin.kepplinger@puri.sm/

v4: (thank you Laurent, Sakari and Rob) many driver changes, see v3 review for
details. they include:
* add get_selection(), remove open() callback
* use gpiod API
* use regulator_bulk API
* fix power supply timing sequence and bindings
* https://lore.kernel.org/linux-media/20210607105213.1211722-1-martin.kepplinger@puri.sm/

v3: (thank you, Laurent)
* use do_div() for divisions
* reset-gpios DT property name instead of rst-gpios
* improve the dt-bindings
* add the phone-devel list
* https://lore.kernel.org/linux-media/20210531120737.168496-1-martin.kepplinger@puri.sm/

v2:
sent a bit early due to stupid mistakes
* fix build issues
* fix dtschema issues
* add enable for arm64 defconfig
* https://lore.kernel.org/linux-media/20210530212337.GA15366@duo.ucw.cz/T/#t

v1:

SK Hynix built the already supported hi556 sensor (and probably much
more). For more information, see https://www.skhynix.com/

The SK Hynix Hi-846 is a 1/4" 8M Pixel CMOS Image Sensor. It supports
usual features like I2C control, CSI-2 for frame data, digital/analog
gain control or test patterns.

This driver supports the 640x480, 1280x720 and 1632x1224 resolution
modes. It supports runtime PM in order not to draw any unnecessary power.

The part is also called YACG4D0C9SHC and a datasheet can be found at
https://product.skhynix.com/products/cis/cis.go

The large sets of partly undocumented register values are for example
found when searching for the hi846_mipi_raw_Sensor.c Android driver.

thanks a lot Geert, but I can't reproduce this on linux-next. Which
tree did you run it against?

What I *do* see is the following during dtbs_check, so I guess I could
remove "orientation" and "rotation" from the example, which would be
kind of sad because these useful properties are not yet too wide know
anyway in the media device driver world...

/home/martin/dev/purism-forks/linux-
next/arch/arm64/boot/dts/freescale/imx8mq-librem5-r2.dt.yaml:
camera-front@20: 'orientation', 'rotation' do not match any of the
regexes: 'pinctrl-[0-9]+'
	From schema: /home/martin/dev/purism-forks/linux-
next/Documentation/devicetree/bindings/media/i2c/hynix,hi846.yaml


if you can be more speicific I'll definitely try to reproduce again
though.

thanks,
                             martin

link-frequencies is present in the example (as it needs to be) but missing
from required properties. I don't know why there's a complaint about
data-lanes though.

This is reproducible on next-20211126.
Is your dt-schema up-to-date?

I also don't know what's wrong with data-lanes (else I would have

it is now, I'm running

make -j7 ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- dt_binding_check
dtbs_check

but I can't reproduce that error. weird.

This needs to be:

$ref: /schemas/graph.yaml#/$defs/port-base

dtschema which has unevaluatedProperties support. I'll be making a
release soonish.
