On recent kernels, the PM8058 L16 (or any other PM8058 LDO-regulator) does not come up if they are supplied by an SMPS-regulator. This is not very strange since the regulators are registered in a long array and the L-regulators are registered before the S-regulators, and if an L-regulator defers, it will never get around to registering the S-regulator that it needs. See arch/arm/boot/dts/qcom-apq8060-dragonboard.dts: pm8058-regulators { (...) vdd_l13_l16-supply = <&pm8058_s4>; (...) Ooops. Fix this by moving the PM8058 S-regulators first in the array. Do the same for the PM8901 S-regulators (though this is currently not causing any problems with out device trees) so that the pattern of registration order is the same on all PMnnnn chips.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
