+There are only '#clock-cells' removal from SM8350 QMP PHY nodes, because

+
+Add support for IPQ8074 since it uses the same PLL setup, however it uses
+slightly different Alpha PLL config.
+
+Alpha PLL config was obtained by dumping PLL registers from a running

+Subject: [PATCH] clk: qcom: clk-rcg2: add rcg2 mux ops
+
+An RCG may act as a mux that switch between 2 parents.
+This is the case on IPQ6018 and IPQ8074 where the APCS core clk that feeds
+the CPU cluster clock just switches between XO and the PLL that feeds it.
+
+Add the required ops to add support for this special configuration and use
+the generic mux function to determine the rate.
+
+This way we dont have to keep a essentially dummy frequency table to use
+RCG2 as a mux.

+Subject: [PATCH] clk: qcom: apss-ipq6018: fix apcs_alias0_clk_src
+
+While working on IPQ8074 APSS driver it was discovered that IPQ6018 and
+IPQ8074 use almost the same PLL and APSS clocks, however APSS driver is
+currently broken.
+
+More precisely apcs_alias0_clk_src is broken, it was added as regmap_mux
+clock.
+However after debugging why it was always stuck at 800Mhz, it was figured
+out that its not regmap_mux compatible at all.
+It is a simple mux but it uses RCG2 register layout and control bits, so
+utilize the new clk_rcg2_mux_closest_ops to correctly drive it while not
+having to provide a dummy frequency table.
+
+While we are here, use ARRAY_SIZE for number of parents.
+
+Tested on IPQ6018-CP01-C1 reference board and multiple IPQ8074 boards.

+
+Since it already got merged, start by correcting the register space

+Subject: [PATCH] arm64: dts: qcom: ipq8074: add thermal nodes
+
+IPQ8074 has a tsens v2.3.0 peripheral which monitors
+temperatures around the various subsystems on the
+die.
+
+So lets add the tsens and thermal zone nodes, passive
+CPU cooling will come in later patches after CPU frequency
+scaling is supported.

+Subject: [PATCH] arm64: dts: qcom: ipq8074: add clocks to APCS
+
+APCS now has support for providing the APSS clocks as the child device
+for IPQ8074.
+
+So, add the A53 PLL and XO clocks in order to use APCS as the CPU
+clocksource for APSS scaling.

+
+Convert the IPQ8074 GCC driver to use parent data instead of global
+name matching.
+
+Utilize ARRAY_SIZE for num_parents instead of hardcoding the value.

+Subject: [PATCH] clk: qcom: reset: Allow specifying custom reset delay
+
+The amount of time required between asserting and deasserting the reset
+signal can vary depending on the involved hardware component. Sometimes
+1 us might not be enough and a larger delay is necessary to conform to
+the specifications.
+
+Usually this is worked around in the consuming drivers, by replacing
+reset_control_reset() with a sequence of reset_control_assert(), waiting
+for a custom delay, followed by reset_control_deassert().
+
+However, in some cases the driver making use of the reset is generic and
+can be used with different reset controllers. In this case the reset
+time requirement is better handled directly by the reset controller
+driver.
+
+Make this possible by adding an "udelay" field to the qcom_reset_map
+that allows setting a different reset delay (in microseconds).

+Subject: [PATCH] clk: qcom: reset: support resetting multiple bits
+
+This patch adds the support for giving the complete bitmask
+in reset structure and reset operation will use this bitmask
+for all reset operations.
+
+Currently, reset structure only takes a single bit for each reset
+and then calculates the bitmask by using the BIT() macro.
+
+However, this is not sufficient anymore for newer SoC-s like IPQ8074,
+IPQ6018 and more, since their networking resets require multiple bits
+to be asserted in order to properly reset the HW block completely.
+
+So, in order to allow asserting multiple bits add "bitmask" field to
+qcom_reset_map, and then use that bitmask value if its populated in the
+driver, if its not populated, then we just default to existing behaviour
+and calculate the bitmask on the fly.

+
+Downstream QCA 5.4 kernel defines networking resets which are not present
+in the mainline kernel but are required for the networking drivers.
+
+So, port the downstream resets and avoid using magic values for mask,
+construct mask for resets which require multiple bits to be set/cleared.

+Subject: [PATCH] clk: qcom: ipq8074: populate fw_name for all parents
+
+It appears that having only .name populated in parent_data for clocks
+which are only globally searchable currently will not work as the clk core
+won't copy that name if there is no .fw_name present as well.
+
+So, populate .fw_name for all parent clocks in parent_data.

+ clients
+
+Some PMIC functions such as the RRADC need to be aware of the PMIC
+chip revision information to implement errata or otherwise adjust
+behaviour, export the PMIC information to enable this.
+
+This is specifically required to enable the RRADC to adjust
+coefficients based on which chip fab the PMIC was produced in,
+this can vary per unique device and therefore has to be read at
+runtime.

+Subject: [PATCH] regulator: qcom_spmi: add support for PMP8074 regulators
+
+PMP8074 is a companion PMIC for the Qualcomm IPQ8074 WiSoC-s.
+
+It features 5 HF-SMPS and 13 LDO regulators.
+
+HF-SMPS regulators are Buck HFS430 regulators.
+L1, L2 and L3 are HT_N1200_ST subtype LDO regulators.
+L4 is HT_N300_ST subtype LDO regulator.
+L5 and L6 are HT_P600 subtype LDO regulators.
+L7, L11, L12 and L13 are HT_P150 subtype LDO regulators.
+L10 is HT_P50 subtype LDO regulator.
+
+This commit adds support for all of the buck regulators and LDO-s except
+for L10 as I dont have documentation on its output voltage range.
+
+S3 is the CPU cluster voltage supply, S4 supplies the UBI32 NPU cores
+and L11 is the SDIO/eMMC I/O voltage regulator required for high speeds.

+
+IPQ8074 Gen3 PCIe PHY uses 250MHz as the pipe clock rate instead of 125MHz
+like every other PCIe QMP PHY does, so make it configurable as part of the

+Subject: [PATCH] clk: qcom: rcg2: Cache CFG register updates for parked RCGs
+
+As GDSCs are turned on and off some associated clocks are momentarily
+enabled for house keeping purposes. For this, and similar, purposes the
+"shared RCGs" will park the RCG on a source clock which is known to be
+available.
+When the RCG is parked, a safe clock source will be selected and
+committed, then the original source would be written back and upon enable
+the change back to the unparked source would be committed.
+
+But starting with SM8350 this fails, as the value in CFG is committed by
+the GDSC handshake and without a ticking parent the GDSC enablement will
+time out.
+
+This becomes a concrete problem if the runtime supended state of a
+device includes disabling such rcg's parent clock. As the device
+attempts to power up the domain again the rcg will fail to enable and
+hence the GDSC enablement will fail, preventing the device from
+returning from the suspended state.
+
+This can be seen in e.g. the display stack during probe on SM8350.
+
+To avoid this problem, the software needs to ensure that the RCG is
+configured to a active parent clock while it is disabled. This is done
+by caching the CFG register content while the shared RCG is parked on
+this safe source.

+Writes to M, N and D registers are committed as they are requested. New
+helpers for get_parent() and recalc_rate() are extracted from their
+previous implementations and __clk_rcg2_configure() is modified to allow
+it to operate on the cached value.

+Subject: [PATCH] dt-bindings: arm: qcom: document qcom,msm-id and
+ qcom,board-id
+
+The top level qcom,msm-id and qcom,board-id properties are utilized by
+bootloaders on Qualcomm MSM platforms to determine which device tree
+should be used and passed to the kernel.
+
+The commit b32e592d3c28 ("devicetree: bindings: Document qcom board
+compatible format") from 2015 was a consensus during discussion about
+upstreaming qcom,msm-id and qcom,board-id fields. There are however still
+problems with that consensus:
+1. It was reached 7 years ago but it turned out its implementation did
+ not reach all possible products.
+
+2. Initially additional tool (dtbTool) was needed for parsing these
+ fields to create a QCDT image consisting of multiple DTBs, later the
+ bootloaders were improved and they use these qcom,msm-id and
+ qcom,board-id properties directly.
+
+3. Extracting relevant information from the board compatible requires
+ this additional tool (dtbTool), which makes the build process more
+ complicated and not easily reproducible (DTBs are modified after the
+ kernel build).
+
+4. Some versions of Qualcomm bootloaders expect these properties even
+ when booting with a single DTB. The community is stuck with these
+ bootloaders thus they require properties in the DTBs.
+
+Since several upstreamed Qualcomm SoC-based boards require these
+properties to properly boot and the properties are reportedly used by
+bootloaders, document them along with the bindings header with constants
+used by: bootloader, some DTS and socinfo driver.

+Subject: [PATCH] clk: qcom: ipq8074: populate fw_name for usb3phy-s
+
+Having only .name populated in parent_data for clocks which are only
+globally searchable currently will not work as the clk core won't copy
+that name if there is no .fw_name present as well.
+
+So, populate .fw_name for usb3phy clocks in parent_data as they were
+missed by me in ("clk: qcom: ipq8074: populate fw_name for all parents").

+Subject: [PATCH] clk: qcom: clk-rcg2: introduce support for multiple conf for
+ same freq
+
+Some RCG frequency can be reached by multiple configuration.
+
+We currently declare multiple configuration for the same frequency but
+that is not supported and always the first configuration will be taken.
+
+These multiple configuration are needed as based on the current parent
+configuration, it may be needed to use a different configuration to
+reach the same frequency.
+
+To handle this introduce 2 new macro, FM and C.
+
+- FM is used to declare an empty freq_tbl with just the frequency and an
+ array of confs to insert all the config for the provided frequency.
+
+- C is used to declare a fre_conf where src, pre_div, m and n are
+ provided.
+
+The driver is changed to handle this special freq_tbl and select the
+correct config by calculating the final rate and deciding based on the
+one that is less different than the requested one.

+ conf
+
+Rework nss_port5/6 to use the new multiple configuration implementation
+and correctly fix the clocks for these port under some corner case.
+
+This is particularly relevant for device that have 2.5G or 10G port
+connected to port5 or port 6 on ipq8074. As the parent are shared
+across multiple port it may be required to select the correct
+configuration to accomplish the desired clock. Without this patch such
+port doesn't work in some specific ethernet speed as the clock will be
+set to the wrong frequency as we just select the first configuration for
+the related frequency instead of selecting the best one.

+Subject: [PATCH] cpufreq: qcom-nvmem: reuse socinfo SMEM item struct
+
+Now that socinfo SMEM item struct and defines have been moved to a header
+so we can utilize that instead.
+
+Now the SMEM value can be accesed directly, there is no need for defining
+the ID for the SMEM request as well.

+Subject: [PATCH] cpufreq: qcom-nvmem: make qcom_cpufreq_get_msm_id() return
+ the SoC ID
+
+Currently, qcom_cpufreq_get_msm_id() does not simply return the SoC ID
+after getting it via SMEM call but instead uses an enum to encode the
+matched SMEM ID to 2 variants of MSM8996 which are then used in
+qcom_cpufreq_kryo_name_version() to set the supported version.
+
+This prevents qcom_cpufreq_get_msm_id() from being universal and its doing
+more than its name suggests, so lets make it just return the SoC ID
+directly which allows matching directly on the SoC ID and removes the need
+for msm8996_version enum which simplifies the driver.
+It also allows reusing the qcom_cpufreq_get_msm_id() for new SoC-s.

+Subject: [PATCH] cpufreq: qcom-nvmem: add support for IPQ8074
+
+IPQ8074 comes in 2 families:
+* IPQ8070A/IPQ8071A (Acorn) up to 1.4GHz
+* IPQ8072A/IPQ8074A/IPQ8076A/IPQ8078A (Hawkeye) up to 2.2GHz
+
+So, in order to be able to share one OPP table lets add support for IPQ8074
+family based of SMEM SoC ID-s as speedbin fuse is always 0 on IPQ8074.
+
+IPQ8074 compatible is blacklisted from DT platdev as the cpufreq device
+will get created by NVMEM CPUFreq driver.
