soc: qcom: ice: make of_qcom_ice_get() static

2025-02-14T17:37:16+00:00

There's no consumer calling it left, make the method static.

soc: qcom: ice: introduce devm_of_qcom_ice_get

2025-02-14T17:37:16+00:00

Callers of of_qcom_ice_get() leak the device reference taken by
of_find_device_by_node(). Introduce devm variant for of_qcom_ice_get().
Existing consumers need the ICE instance for the entire life of their
device, thus exporting qcom_ice_put() is not required.

soc: qcom: Rework BCM_TCS_CMD macro

2024-12-26T05:44:41+00:00

Reworked BCM_TCS_CMD macro in order to fix warnings from sparse:

drivers/clk/qcom/clk-rpmh.c:270:28: warning: restricted __le32 degrades to integer
drivers/clk/qcom/clk-rpmh.c:270:28: warning: restricted __le32 degrades to integer

While at it, used u32_encode_bits which made the code easier to
follow and removed unnecessary shift definitions.

The use of cpu_to_le32 was wrong and thus removed.

soc: qcom: rpmh-rsc: Enhance check for VRM in-flight request

2024-04-21T17:11:40+00:00

Each RPMh VRM accelerator resource has 3 or 4 contiguous 4-byte aligned
addresses associated with it. These control voltage, enable state, mode,
and in legacy targets, voltage headroom. The current in-flight request
checking logic looks for exact address matches. Requests for different
addresses of the same RPMh resource as thus not detected as in-flight.

Add new cmd-db API cmd_db_match_resource_addr() to enhance the in-flight
request check for VRM requests by ignoring the address offset.

This ensures that only one request is allowed to be in-flight for a given
VRM resource. This is needed to avoid scenarios where request commands are
carried out by RPMh hardware out-of-order leading to LDO regulator
over-current protection triggering.

Move internal SPM driver structures to the driver itself, removing them
from the public API. The CPUidle driver doesn't use them at all.

soc: qcom: socinfo: rename PM2250 to PM4125

2024-01-28T03:45:49+00:00

It seems, the only actual mentions of PM2250 can be found are related to
the Qualcomm RB1 platform. However even RB1 schematics use PM4125 as a
PMIC name. Rename PM2250 to PM4125 to follow the documentation.

soc: qcom: Make the Qualcomm UFS/SDCC ICE a dedicated driver

2023-04-07T19:08:39+00:00

This takes the already existing duplicated support in both ufs-qcom
and sdhci-msm drivers and makes it a dedicated driver that can be used
by both mentioned drivers.

The reason for this is because, staring with SM8550, the ICE IP block
is shared between UFS and SDCC, which means we need to probe a dedicated
device and share it between those two consumers.

So let's add the ICE dedicated driver as a soc driver.

Platforms that already have ICE supported, will use it as a library
as the of_qcom_ice_get will return an ICE instance created for the
consumer device. This allows the backwards compatibility with old-style
devicetree approach.

Also, add support to HW version 4.x since it works out-of-the-box with
the current driver. The 4.x HW version is found on SM8550 platform.
