This patch series build on top of Mehdi's introduction of the
devm_v4l2_sensor_clk_get() helper (see [1]) to drastically reduce
cargo-cult in camera sensor drivers.

A large number of camera sensor drivers directly use the
"clock-frequency" property to retrieve the effective or desired external
clock rate. This is standard behaviour on ACPI platforms that don't
implement MIPI DisCo for Imaging, but usage of the property has leaked
to OF-based platforms, due to a combination of historical reasons (using
"clock-frequency" was initially considered right until before the
introduction of "assigned-clock-rates") and plain cargo-cult.

Applied, thanks!

I'm afraid that's too soon. This will introduce a breakage without a
corresponding change to the camera sensor driver.

I will post a v2 with the patches reordered. We could merge the V4L2
side in a rc1-based stable branch and merge than in the arm-soc tree as

You cannot ("cannot" as not following the process) merge drivers into
DTS branch.

well, but I think we can also delay the .dts changes to the next kernel

All users of DTS will be anyway affected and commit msg should address that.

version. Do you have a preference ?
