arm64: dts: qcom: msm8916: Rename &msmgpio -> &tlmm

2023-09-13T07:48:18Z

[ Upstream commit 41e22c2ff38eaea777f1158071539e659aa7980d ] MSM8916 is the only ARM64 Qualcomm SoC that is still using the old &msmgpio name. Change this to &tlmm to avoid confusion. Note that the node ordering does not change because the MSM8916 device trees have pinctrl separated at the bottom (similar to sc7180).

arm64: dts: qcom: msm8916: Define regulator constraints next to usage

2023-09-13T07:48:18Z

[ Upstream commit b0a8f16ae4a0eb423122256691849b3ebc64efc2 ] Right now each MSM8916 device has a huge block of regulator constraints with allowed voltages for each regulator. For lack of better documentation these voltages are often copied as-is from the vendor device tree, without much extra thought. Unfortunately, the voltages in the vendor device trees are often misleading or even wrong, e.g. because: - There is a large voltage range allowed and the actual voltage is only set somewhere hidden in some messy vendor driver. This is often the case for pm8916_{l14,l15,l16} because they have a broad range of 1.8-3.3V by default. - The voltage is actually wrong but thanks to the voltage constraints in the RPM firmware it still ends up applying the correct voltage. To have proper regulator constraints it is important to review them in context of the usage. The current setup in the MSM8916 device trees makes this quite hard because each device duplicates the standard voltages for components of the SoC and mixes those with minor device-specific additions and dummy voltages for completely unused regulators. The actual usage of the regulators for the SoC components is in msm8916-pm8916.dtsi, so it can and should also define the related voltage constraints. These are not board-specific but defined in the APQ8016E/PM8916 Device Specification. The board DT can then focus on describing the actual board-specific regulators, which makes it much easier to review and spot potential mistakes there. Note that this commit does not make any functional change. All used regulators still have the same regulator constraints as before. Unused regulators do not have regulator constraints anymore because most of these were too broad or even entirely wrong. They should be added back with proper voltage constraints when there is an actual usage.

arm64: dts: qcom: msm8916: Disable audio codecs by default

arm64: dts: qcom: msm8916: Fix regulator constraints

2023-09-13T07:48:18Z

[ Upstream commit 355750828c5519c88de6ac0d09202d2a7e5892c5 ] 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.
