Goal of the msm8916-pm8916.dtsi is to reduce the boilerplate necessary to create a device tree for a typical board with the MSM8916 SoC combined with the PM8916 PMIC. > 99% of all MSM8916 boards use the same standard setup where many of the PM8916 regulators have a fixed purpose and only some are left up for board-specific use. While MSM8916 (and perhaps MSM8939 soon) is currently the only platform with such an include, it has definitely proven useful. With more than 30 boards using it (not all of them upstream yet) it simplifies the review a lot and reduces the chance of configuring the standard components incorrectly. In preparation of extending its scope slightly, add a comment at the top that clearly explains what the .dtsi represents and when it should (or should not) be used. Signed-off-by:

Some of the power supplies for the analog audio codec in PM8916 are wired externally. While most boards use the regulators currently specified in pm8916.dtsi, in theory it could be connected differently. We already have msm8916-pm8916.dtsi that models that standard setup used by most devices so move the -supply properties there and keep the base pm8916.dtsi independent. Currently all MSM8916 boards in mainline make use of msm8916-pm8916.dtsi, so it is not necessary to adjust any other boards. Signed-off-by:

The regulator constraints for most MSM8916 devices (except DB410c) were originally taken from Qualcomm's msm-3.10 vendor device tree (for lack of better documentation). Unfortunately it turns out that Qualcomm's voltages are slightly off as well and do not match the voltage constraints applied by the RPM firmware. This means that we sometimes request a specific voltage but the RPM firmware actually applies a much lower or higher voltage. This is particularly critical for pm8916_l11 which is used as SD card VMMC regulator: The SD card can choose a voltage from the current range of 1.8 - 2.95V. If it chooses to run at 1.8V we pretend that this is fine but the RPM firmware will still silently end up configuring 2.95V. This can be easily reproduced with a multimeter or by checking the SPMI hardware registers of the regulator. Fix this by making the voltages match the actual "specified range" in the PM8916 Device Specification which is enforced by the RPM firmware. Signed-off-by:

The 96Boards specification expects a 1.8V power rail on the low-speed expansion connector that is able to provide at least 0.18W / 100 mA. According to the DB410c hardware user manual this is done by connecting both L15 and L16 in parallel with up to 55mA each (for 110 mA total) [1]. Unfortunately the current regulator setup in the DB410c device tree does not implement the specification correctly and only provides 5 mA: - Only L15 is marked always-on, so L16 is never enabled. - Without specifying a load the regulator is put into LPM where it can only provide 5 mA. Fix this by: - Adding proper voltage constraints for L16. - Making L16 always-on. - Adding regulator-system-load for both L15 and L16. 100 mA should be available in total, so specify 50 mA for each. (The regulator hardware can only be in normal (55 mA) or low-power mode (5 mA) so this will actually result in the expected 110 mA total...)

For some reason DB410c has completely bogus regulator constraints that actually just correspond to the programmable voltages which are already provided by the regulator driver. Some of them are not just outside the recommended operating conditions of the APQ8016E SoC but even exceed the absolute maximum ratings, potentially risking permanent device damage. In practice it's not quite as dangerous thanks to the RPM firmware: It turns out that it has its own voltage constraints and silently clamps all regulator requests. For example, requesting 3.3V for L5 (allowed by the current regulator constraints!) still results in 1.8V being programmed in the actual regulator hardware. Experimentation with various voltages shows that the internal RPM voltage constraints roughly correspond to the safe "specified range" in the PM8916 Device Specification (rather than the "programmable range" used inside apq8016-sbc.dtsi right now). Combine those together with some fixed voltages used in the old msm-3.10 device tree from Qualcomm to give DB410c some actually valid voltage constraints.

lpass clocks are usually blocked from HLOS by the firmware and instead are managed by the ADSP. Mark them as reserved and explicitly enable in the CrOS boards that have special, cooperative firmware. The IDP board gets lpass clocks disabled as it doesn't make use of sound anyway and might use Qualcomm firmware that blocks those clocks.
