[PATCH v5 00/13] Add explicit clock vote and enable power-domain for QCOM-ICE

[PATCH v5 00/13] Add explicit clock vote and enable power-domain for QCOM-ICE

[Harshal Dev]

When the kernel is booted without the 'clk_ignore_unused' and
'pd_ignore_unused' command‑line flags, votes for unused clocks and power
domains are dropped by the kernel post late_init and deferred probe
timeout. Depending on the relative timing between the ICE probe and the
kernel disabling the unused clocks and power domains occasional unclocked
register accesses or 'stuck' clocks are observed during QCOM‑ICE probe.
When the 'iface' clock is not voted on, unclocked register access would
be observed. On the other hand, if the associated power-domain for ICE
is not enabled, a 'stuck' clock is observed.

This patch series resolves both of these problems by adding explicit
power‑domain enablement and 'iface' clock‑vote handling to the QCOM‑ICE
driver.

The clock 'stuck' issue was first reported on Qualcomm RideSX4 (sa8775p)
platform: https://lore.kernel.org/all/ZZYTYsaNUuWQg3tR@x1/

Issue with unclocked ICE register access is easily reproducible on
on Qualcomm RB3Gen2 (kodiak) platform when 'clk_ignore_unused' is
not passed on the kernel command-line.

This patch series has been validated on: SM8650-MTP, RB3Gen2 and
Lemans-EVK.

[PATCH v5 01/13] dt-bindings: crypto: qcom,ice: Fix missing power-domain and iface clk

[Harshal Dev]

The DT bindings for inline-crypto engine do not specify the UFS_PHY_GDSC
power-domain and iface clock. Without enabling the iface clock and the
associated power-domain the ICE hardware cannot function correctly and
leads to unclocked hardware accesses being observed during probe.

Fix the DT bindings for inline-crypto engine to require the UFS_PHY_GDSC
power-domain and iface clock for new devices (Eliza and Milos) introduced
in the current release (7.1) with yet-to-stabilize ABI, while preserving
backward compatibility for older devices.

[PATCH v5 02/13] soc: qcom: ice: Allow explicit votes on 'iface' clock for ICE

[Harshal Dev]

Since Qualcomm inline-crypto engine (ICE) is now a dedicated driver
de-coupled from the QCOM UFS driver, it explicitly votes for its required
clocks during probe. For scenarios where the 'clk_ignore_unused' flag is
not passed on the kernel command line, to avoid potential unclocked ICE
hardware register access during probe the ICE driver should additionally
vote on the 'iface' clock.
Also update the suspend and resume callbacks to handle un-voting and voting
on the 'iface' clock.

[PATCH v5 07/13] arm64: dts: qcom: kodiak: Add power-domain and iface clk for ice node

[Harshal Dev]

Qualcomm in-line crypto engine (ICE) platform driver specifies and votes
for its own resources. Before accessing ICE hardware during probe, to
avoid potential unclocked register access issues (when clk_ignore_unused
is not passed on the kernel command line), in addition to the 'core' clock
the 'iface' clock should also be turned on by the driver. This can only be
done if the GCC_UFS_PHY_GDSC power domain is enabled. Specify both the
GCC_UFS_PHY_GDSC power domain and the 'iface' clock in the ICE node for
kodiak.

On thing I noticed in entire patchseries,
https://docs.kernel.org/process/submitting-patches.html
"""
If your patch fixes a bug in a specific commit, e.g. you found an issue 
using git bisect, please use the ‘Fixes:’ tag with at least the first 12 
characters of the SHA-1 ID, and the one line summary. Do not split the 
tag across multiple lines, tags are exempt from the “wrap at 75 columns” 
rule in order to simplify parsing scripts. For example:

Fixes: 54a4f0239f2e ("KVM: MMU: make kvm_mmu_zap_page() return the 
number of pages it actually freed")
"""

Fixes tag need atleast 12 chars and I see other submissions specifying 
12 chars whereas this series specify 13 chars.
Not sure if there's some hard rule on this.

Other than that,
