Subject: [PATCH 2/6] clk: qcom: krait-cc: fix wrong parent order for secondary
mux
The secondary mux parent order is swapped.
This currently doesn't cause problems as the secondary mux is used for idle
clk and as a safe clk source while reprogramming the hfpll.
Each mux have 2 or more output but he always have a safe source to
switch while reprogramming the connected pll. We use a clk notifier to
switch to the correct parent before clk core can apply the correct rate.
The parent to switch is hardcoded in the mux struct.
For the secondary mux the safe source to use is the qsb parent as it's
the only fixed clk as the acpus_aux is a pll that can source from pxo or
from pll8.
The hardcoded safe parent for the secondary mux is set to index 0 that
in the secondary mux map is set to 2.
But the index 0 is actually acpu_aux in the parent list.
Fix the swapped parents to correctly handle idle frequency and output a
sane clk_summary report.

Subject: [PATCH 4/6] clk: qcom: krait-cc: handle secondary mux sourcing out of
acpu_aux
Some bootloader may leave the system in an even more undefined state
with the secondary mux of L2 or other cores sourcing out of the acpu_aux
parent. This results in the clk set to the PXO rate or a PLL8 rate.
The current logic to reset the mux and set them to a defined state only
handle if the mux are configured to source out of QSB. Change this and
force a new and defined state if the current clk is lower than the aux
rate. This way we can handle any wrong configuration where the mux is
sourcing out of QSB (rate 225MHz, currently set to a virtual rate of 1),
PXO rate (rate 25MHz) or PLL8 (needs to be configured to run at 384Mhz).

Subject: [PATCH 6/6] clk: qcom: krait-cc: convert to parent_data API
Modernize the krait-cc driver to parent-data API and refactor to drop
any use of parent_names. From Documentation all the required clocks should
be declared in DTS so fw_name can be correctly used to get the parents
for all the muxes. .name is also declared to save compatibility with old
DT.
While at it also drop some hardcoded index and introduce an enum to make
index values more clear.

Subject: [PATCH] ARM: dts: qcom: ipq8064: disable mmc-ddr-1_8v for sdcc1
It was reported non working mmc with this option enabled.
Both mmc for ipq8064 are supplied by a fixed 3.3v regulator so mmc can't
be run at 1.8v.
Disable it to restore correct functionality of this SoC feature.

Calibrate and tsens_register can fail or PROBE_DEFER. This will cause a
double or a wrong init of the debugfs information. Init debugfs only
with successful probe fixing warning about directory already present.

Subject: [PATCH 3/3] thermal/drivers/qcom/tsens: Rework debugfs file structure
The current tsens debugfs structure is composed by:
- a tsens dir in debugfs with a version file
- a directory for each tsens istance with sensors file to dump all the
sensors value.
This works on the assumption that we have the same version for each
istance but this assumption seems fragile and with more than one tsens
istance results in the version file not tracking each of them.
A better approach is to just create a subdirectory for each tsens
istance and put there version and sensors debugfs file.
Using this new implementation results in less code since debugfs entry
are created only on successful tsens probe.
