regulator: add the WL2868C camera PMIC and its users
Hi all,
this series adds a driver for the WL2868C camera PMIC found on the Lenovo
Legion Tab (TB322FC / "elden", SM8750). The chip is an I2C regulator with
seven LDOs; on this board eight supplies are wired to the camera stack
(S5KJNS sensor, GC08A8 sensor, GT9764 VCM, and the CSIPHY rails).
Changes since v2:
- Bind the board clocks the camera regulator nodes depend on. The board
DTS now defines xo_board, sleep_clk and the two CXO/2 fixed-factor
clocks by reusing the existing definitions from sm8750-mtp.dts, so the
DTB links cleanly instead of failing with 15 phandle errors.
- Register the board compatible in arm/qcom.yaml.
- Fix the reset description in the driver commit message: the GPIO is
released (active-low) during probe and asserted on unbind, which is what
GPIOD_OUT_LOW plus the devm action actually do.
The binding and driver are unchanged in behaviour since v2 apart from
the commit message correction. The camera sensor and lens bindings the
board DTS also references are not part of this series; they are being
submitted separately.
