[PATCH 0/4] support camera found on Gaokun3

[Pengyu Luo]

This series adds support for front camera on Gaokun3(3.0GHz version).
The front sensor is Hi846, this series also fixes a error blocking
Hi846 driver function, and supports more mode on Hi846.

[PATCH 1/4] media: hi846: fix hi846_write_reg_16 handling

[Pengyu Luo]

hi846_write_reg_16() does not clear a positive *err value on success.
pm_runtime_get_if_in_use() returns a positive value when the device
is already in use. When hi846_set_ctrl() passes &ret holding this
positive value) to hi846_write_reg_16(), the function returns with ret
as is, the positive value propagates back as a return code, which
callers interpret as an error.

Fix this by resetting *err to 0 only when it is positive.

[PATCH 2/4] media: hi846: Add 6MP and 8MP mode support

[Pengyu Luo]

Hi846 is an 8MP sensor, but the upstream driver has only supported 2MP
mode for years. This patch adds 6MP and 8MP modes to maximize sensor
utilization.

Note that these modes require 4-lane MIPI CSI-2, as the downstream
driver only exposes 2MP, 6MP, and 8MP configurations in 4-lane
operation on the target device. The register sequences are extracted
from the downstream Windows driver.

[PATCH 3/4] arm64: dts: qcom: sc8280xp: gaokun3: add front camera sensor node

[Pengyu Luo]

Hi846 is found on my Gaokun3, descripting it.

Note that it seems that only Goakun3(3.0GHz) version is equipped with
Hi846. Goakun3(2.69GHz) version is equipped with S5K4H7.

Are there any other noticeable hw differences between the two variants,
that could warrant the DT to be split?

[PATCH 4/4] arm64: dts: qcom: sc8280xp: gaokun3: describe rear camera module information as musch as possible

[Pengyu Luo]

The rear sensor is S5K3L6, describing it but dropping compatible
string, since there is no upstream driver. A funcitonal downstream
driver is in comment.

The VCM is dw9714, describe it.

Please take this patch as a RFC, I am not sure, how much I am allowed
to add without a sensor driver.
