The series aims to upstream some parts of the DTS that are currently found
in the kernel used in the field. This is the first in a series of
activities intended to eventually lead to the use of an official kernel.
Karthikdatt Anantharamrao (1):
arm64: dts: imx8mn-bsh-smm-s2-common: Enable GPU for smms2 and
smms2pro
Michael Trimarchi (3):
arm64: dts: imx8mn-bsh-smm-s2-common: Define suspend voltage threshold
arm64: dts: imx8mn-bsh-smm-s2-common: Leave regulator under hw state
machine
arm64: dts: imx8mn-bsh-smm-s2-common: Keep wifi enable during suspend
Simon Holesch (1):
arm64: dts: imx8mn-bsh-smm-s2-common: Pull Up Console UART pins
Wolfgang Birkner (4):
arm64: dts: imx8mn-bsh-smm-s2-common: Set minimum value for
VDD_DRAM_VPU_GPU
arm64: dts: imx8mn-bsh-smm-s2-common: Set minimum value for VDD_3V3
arm64: dts: imx8mn-bsh-smm-s2-common: Increase drive strength of pmic
irq
arm64: dts: imx8mn-bsh-smm-s2-common: Disable PMIC SNVS reset target
state

VDD_DRAM was disabled on standby, therefore the reference hardware did not
wake up reliable. Use PMIC reset target state READY instead of SNVS, to
keep VDD_DRAM active during standby.

I would love to understand why these voltages are set.
Could you please explain a bit further why this change is done. What
worst case? What happens if voltages aren't adjusted? What is the
current voltage (before this patch is applied?).

The commit message does not explain why the software control of the
regulator's enable state is changed? Maybe this should be in the 2/9?

Is it possible to add a note _why_ these regulators must be controlled
by the state machine and not by the software?

Setting this to PMIC's minimum value has little benefits because the
voltage can't be set lower than it anyways.
AFICS, the idea of the regulator-min-microvolt and the
regulator-max-microvolt is to protect a system which can't tolerate
lower/higher than NNN voltage. So, basically, these properties are
meaningful when PMIC can go higher / lower than the system design
tolerates. In these cases the constrains set in device tree should be
strictier than the PMIC's range.
The existing regulator-min-microvolt = <700000>; could have resulted
from the knowledge that the minimum voltage devices connected to the
BUCK3 (5 in data-sheet) can survive is 700 mV. Dropping this to 500mV
just because PMIC can go there might be plain wrong, and in some case
get the device(s) connected to BUCK3/5 upset..
So, please provide better (more) rationale for this change.

Same comment as for 6/9. Please provide better rationale than the PMIC's
limits.

There is something I'm not quite sure I understand. Lookin at the
BD71847 data-sheet, the VDD_DRAM is OFF at READY.
(Page 27, Table 3-8. Voltage Rails ON/OFF for Respective Power State)

Please, explain.
