2025-06-15dt-bindings: phy: renesas,usb2-phy: Document RZ/V2N SoC supportLad Prabhakar
Document support for the USB2.0 phy found on the Renesas RZ/V2N (R9A09G056) SoC. The USB2.0 phy is functionally identical to that on the RZ/V2H(P) SoC, so no driver changes are needed. The existing `renesas,usb2-phy-r9a09g057` compatible will be used as a fallback for the RZ/V2N SoC.

2025-06-15scsi: ufs: qcom : Refactor phy_power_on/off callsNitin Rawat
Commit 3f6d1767b1a0 ("phy: ufs-qcom: Refactor all init steps into phy_poweron") moved the phy_power_on/off from ufs_qcom_setup_clocks to suspend/resume func. To have a better power saving, remove the phy_power_on/off calls from resume/suspend path and put them back to ufs_qcom_setup_clocks, so that PHY regulators & clks can be turned on/off along with UFS's clocks. Since phy phy_power_on is separated out from phy calibrate, make separate calls to phy_power_on calls from ufs qcom driver.

2025-06-15phy: qcom-qmp-ufs: refactor qmp_ufs_power_offNitin Rawat
In qmp_ufs_power_off, the PHY is already powered down by asserting QPHY_PCS_POWER_DOWN_CONTROL. Therefore, additional phy_reset and stopping SerDes are unnecessary. Also this approach does not align with the phy HW programming guide. Thus, refactor qmp_ufs_power_off to remove the phy_reset and stop SerDes calls to simplify the code and ensure alignment with the PHY HW programming guide.

Commit 052553af6a31 ("ufs/phy: qcom: Refactor to use phy_init call") puts enabling regulators & clks, calibrating UFS PHY, starting serdes and polling PCS ready status into phy_power_on. In Current code regulators enable, clks enable, calibrating UFS PHY, start_serdes and polling PCS_ready_status are part of phy_power_on. UFS PHY registers are retained after power collapse, meaning calibrating UFS PHY, start_serdes and polling PCS_ready_status can be done only when hba is powered_on, and not needed every time when phy_power_on is called during resume. Hence keep the code which enables PHY's regulators & clks in phy_power_on and move the rest steps into phy_calibrate function. Refactor the code to retain PHY regulators & clks in phy_power_on and move out rest of the code to new phy_calibrate function. Also move reset_control_assert to qmp_ufs_phy_calibrate to align with Hardware programming guide.

2025-06-08tools/power turbostat: Avoid probing the same perf countersZhang Rui
For the RAPL package energy status counter, Intel and AMD share the same perf_subsys and perf_name, but with different MSR addresses. Both rapl_counter_arch_infos[0] and rapl_counter_arch_infos[1] are introduced to describe this counter for different Vendors. As a result, the perf counter is probed twice, and causes a failure in in get_rapl_counters() because expected_read_size and actual_read_size don't match. Fix the problem by skipping the already probed counter. Note, this is not a perfect fix. For example, if different vendors/platforms use the same MSR value for different purpose, the code can be fooled when it probes a rapl_counter_arch_infos[] entry that does not belong to the running Vendor/Platform. In a long run, better to put rapl_counter_arch_infos[] into the platform_features so that this becomes Vendor/Platform specific.

2025-06-08tools/power turbostat: Allow probing RAPL with platform_features->rapl_msrs ↵Zhang Rui
cleared platform_features->rapl_msrs describes the RAPL MSRs supported. While RAPL Perf counters can be exposed from different kernel backend drivers, e.g. RAPL MSR I/F driver, or RAPL TPMI I/F driver. Thus, turbostat should first blindly probe all the available RAPL Perf counters, and falls back to the RAPL MSR counters if they are listed in platform_features->rapl_msrs. With this, platforms that don't have RAPL MSRs can clear the platform_features->rapl_msrs bits and use RAPL Perf counters only.

2025-06-08tools/power turbostat: Clean up add perf/msr counter logicZhang Rui
Increase the code readability by moving the no_perf/no_msr flag and the cai->perf_name/cai->msr sanity checks into the counter probe functions. No functional change. Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2025-06-08tools/power turbostat: Introduce add_msr_counter()Zhang Rui
probe_rapl_msr() is reused for probing RAPL MSR counters, cstate MSR counters and MPERF/APERF/SMI MSR counters, thus its name is misleading. Similar to add_perf_counter(), introduce add_msr_counter() to probe a counter via MSR. Introduce wrapper function add_rapl_msr_counter() at the same time to add extra check for Zero return value for specified RAPL counters. No functional change intended.

2025-06-08tools/power turbostat: Remove add_msr_perf_counter_()Zhang Rui
As the only caller of add_msr_perf_counter_(), add_msr_perf_counter() just gives extra debug output on top. There is no need to keep both functions. Remove add_msr_perf_counter_() and move all the logic to add_msr_perf_counter(). No functional change. Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
