mmc: sdhci_am654: Disable HS400 for AM62P SR1.0 and SR1.1

2025-08-21T09:07:16+00:00

This adds SDHCI_AM654_QUIRK_DISABLE_HS400 quirk which shall be used
to disable HS400 support. AM62P SR1.0 and SR1.1 do not support HS400
due to errata i2458 [0] so disable HS400 for these SoC revisions.

mmc: sdhci-of-arasan: Ensure CD logic stabilization before power-up

2025-08-18T09:43:27+00:00

During SD suspend/resume without a full card rescan (when using
non-removable SD cards for rootfs), the SD card initialization may fail
after resume. This occurs because, after a host controller reset, the
card detect logic may take time to stabilize due to debounce logic.
Without waiting for stabilization, the host may attempt powering up the
card prematurely, leading to command timeouts during resume flow.
Add sdhci_arasan_set_power_and_bus_voltage() to wait for the card detect
stable bit before power up the card. Since the stabilization time
is not fixed, a maximum timeout of one second is used to ensure
sufficient wait time for the card detect signal to stabilize.

mmc: sdhci-pci-gli: GL9763e: Mask the replay timer timeout of AER

2025-08-18T09:38:24+00:00

Due to a flaw in the hardware design, the GL9763e replay timer frequently
times out when ASPM is enabled. As a result, the warning messages will
often appear in the system log when the system accesses the GL9763e
PCI config. Therefore, the replay timer timeout must be masked.

Pull power management updates from Rafael Wysocki:
 "As is tradition, cpufreq is the part with the largest number of
  updates that include core fixes and cleanups as well as updates of
  several assorted drivers, but there are also quite a few updates
  related to system sleep, mostly focused on asynchronous suspend and
  resume of devices and on making the integration of system suspend
  and resume with runtime PM easier.

  Runtime PM is also updated to allow some code duplication in drivers
  to be eliminated going forward and to work more consistently overall
  in some cases.

  Apart from that, there are some driver core updates related to PM
  domains that should help to address ordering issues with devm_ cleanup
  routines relying on PM domains, some assorted devfreq updates
  including core fixes and cleanups, tooling updates, and documentation
  and MAINTAINERS updates.

  Specifics:

   - Fix two initialization ordering issues in the cpufreq core and a
     governor initialization error path in it, and clean it up (Lifeng
     Zheng)

   - Add Granite Rapids support in no-HWP mode to the intel_pstate
     cpufreq driver (Li RongQing)

   - Make intel_pstate always use HWP_DESIRED_PERF when operating in the
     passive mode (Rafael Wysocki)

   - Allow building the tegra124 cpufreq driver as a module (Aaron
     Kling)

   - Do minor cleanups for Rust cpufreq and cpumask APIs and fix
     MAINTAINERS entry for cpu.rs (Abhinav Ananthu, Ritvik Gupta, Lukas
     Bulwahn)

   - Clean up assorted cpufreq drivers (Arnd Bergmann, Dan Carpenter,
     Krzysztof Kozlowski, Sven Peter, Svyatoslav Ryhel, Lifeng Zheng)

   - Add the NEED_UPDATE_LIMITS flag to the CPPC cpufreq driver
     (Prashant Malani)

   - Fix minimum performance state label error in the amd-pstate driver
     documentation (Shouye Liu)

   - Add the CPUFREQ_GOV_STRICT_TARGET flag to the userspace cpufreq
     governor and explain HW coordination influence on it in the
     documentation (Shashank Balaji)

   - Fix opencoded for_each_cpu() in idle_state_valid() in the DT
     cpuidle driver (Yury Norov)

   - Remove info about non-existing QoS interfaces from the PM QoS
     documentation (Ulf Hansson)

   - Use c_* types via kernel prelude in Rust for OPP (Abhinav Ananthu)

   - Add HiSilicon uncore frequency scaling driver to devfreq (Jie Zhan)

   - Allow devfreq drivers to add custom sysfs ABIs (Jie Zhan)

   - Simplify the sun8i-a33-mbus devfreq driver by using more devm
     functions (Uwe Kleine-König)

   - Fix an index typo in trans_stat() in devfreq (Chanwoo Choi)

   - Check devfreq governor before using governor->name (Lifeng Zheng)

   - Remove a redundant devfreq_get_freq_range() call from

   - Limit max_freq with scaling_min_freq in devfreq (Lifeng Zheng)

   - Replace sscanf() with kstrtoul() in set_freq_store() (Lifeng Zheng)

   - Extend the asynchronous suspend and resume of devices to handle
     suppliers like parents and consumers like children (Rafael Wysocki)

   - Make pm_runtime_force_resume() work for drivers that set the
     DPM_FLAG_SMART_SUSPEND flag and allow PCI drivers and drivers that
     collaborate with the general ACPI PM domain to set it (Rafael
     Wysocki)

   - Add kernel parameter to disable asynchronous suspend/resume of
     devices (Tudor Ambarus)

   - Drop redundant might_sleep() calls from some functions in the
     device suspend/resume core code (Zhongqiu Han)

   - Fix the handling of monitors connected right before waking up the
     system from sleep (tuhaowen)

     information in the power domains DT binding (Rafael Wysocki)

   - Update PM header inclusions to follow the IWYU (Include What You
     Use) principle (Andy Shevchenko)

   - Add flags to specify power on attach/detach for PM domains, make
     the driver core detach PM domains in device_unbind_cleanup(), and
     drop the dev_pm_domain_detach() call from the platform bus type
     (Claudiu Beznea)

   - Improve Python binding's Makefile for cpupower (John B. Wyatt IV)

   - Fix printing of CORE, CPU fields in cpupower-monitor (Gautham

mmc: loongson2: Unify the function prefixes for loongson2_mmc_pdata

2025-07-16T10:04:40+00:00

The function prefixes for loongson2_mmc_pdata follow two naming
conventions: SoC-based and DMA-based.

First, DMA-based prefixes are the preferred choice, as they clearly
highlight differences, such as prepare_dma; however, for functions
related to SoC, such as reorder_cmd_data, it is agreed to use the
smallest SoC name as the fallback prefix, such as ls2k0500.

No functional change intended.
