2025-05-22dt-bindings: mmc: sdhci-of-dwcmhsc: Allow use of a power-domainJonas Karlman
The commit 7e856617a1f3 ("dt-bindings: mmc: Add support for rk3576 eMMC") limited use of power-domains to Rockchip RK3576. Remove the power-domains: false to allow use of power-domains with more controllers, e.g. with SDHCI on Rockchip RK3528.

2025-05-19mmc: sdhci_am654: Add SDHCI_QUIRK2_SUPPRESS_V1P8_ENA quirk to am62 compatibleJudith Mendez
Add a new struct for platform data for the ti,am62-sdhci compatible to apply additional quirks, namely "SDHCI_QUIRK2_SUPPRESS_V1P8_ENA", to host controllers with am62 compatible. Note, the fix was originally introduced by commit 941a7abd4666 ("mmc: sdhci_am654: Add sdhci_am654_start_signal_voltage_switch") but was found to be applied too broadly and had to be reverted.

2025-05-19mmc: host: sdhci-esdhc-imx: refactor the system PM logicLuke Wang
Current suspend/resume logic has one issue. In suspend, will config register when call sdhci_suspend_host(), but at this time, can't guarantee host in runtime resume state. If not, the per clock is gate off, access register will hang. In sdhci_esdhc_suspend/sdhci_esdhc_resume, remove sdhci_suspend_host() and sdhci_resume_host(), all are handled in runtime PM callbacks except the wakeup irq setting. For wakeup irq setting, use pm_runtime_get_sync() in sdhci_esdhc_suspend() to make sure clock gate on. Remove pinctrl_pm_select_default_state() in sdhci_esdhc_resume, because pm_runtime_force_resume() already config the pinctrl state according to ios timing, and here config the default pinctrl state again is wrong for SDIO3.0 device if it keep power in suspend.

2025-05-14mmc: sdhci-of-dwcmshc: add PD workaround on RK3576Nicolas Frattaroli
RK3576's power domains have a peculiar design where the PD_NVM power domain, of which the sdhci controller is a part, seemingly does not have idempotent runtime disable/enable. The end effect is that if PD_NVM gets turned off by the generic power domain logic because all the devices depending on it are suspended, then the next time the sdhci device is unsuspended, it'll hang the SoC as soon as it tries accessing the CQHCI registers. RK3576's UFS support needed a new dev_pm_genpd_rpm_always_on function added to the generic power domains API to handle what appears to be a similar hardware design. Use this new function to ask for the same treatment in the sdhci controller by giving rk3576 its own platform data with its own postinit function. The benefit of doing this instead of marking the power domains always on in the power domain core is that we only do this if we know the platform we're running on actually uses the sdhci controller. For others, keeping PD_NVM always on would be a waste, as they won't run into this specific issue. The only other IP in PD_NVM that could be affected is FSPI0. If it gets a mainline driver, it will probably want to do the same thing.

2025-05-14mmc: cavium-thunderx: Use non-hybrid PCI devres APIPhilipp Stanner
cavium-thunderx enables its PCI device with pcim_enable_device(). This, implicitly, switches the function pci_request_regions() into managed mode, where it becomes a devres function. The PCI subsystem wants to remove this hybrid nature from its interfaces. To do so, users of the aforementioned combination of functions must be ported to non-hybrid functions. Moreover, since both functions are already managed in this driver, the calls to pci_release_regions() are unnecessary. Remove the calls to pci_release_regions(). Replace the call to sometimes-managed pci_request_regions() with one to the always-managed pcim_request_all_regions().

2025-05-14mmc: sdhci-esdhc-imx: switch standard tuning to manual tuningLuke Wang
Current standard tuning has some limitations: 1. Standard tuning only try 40 times to find first pass window, but this pass window maybe not the best pass window. 2. Sometimes there are two tuning pass windows and the gap between those two windows may only have one cell. If tuning step > 1, the gap may just be skipped and host assumes those two windows as a continuous windows. This will cause a bad delay cell near the gap to be selected. 3. Standard tuning logic need to detect at least one success and failure to pass the tuning. If all cells in the tuning window pass, the hardware will not set the SDHCI_CTRL_TUNED_CLK bit, causing tuning failed. 4. Standard tuning logic only check the CRC, do not really compare the data pattern. If data pins are connected incorrectly, standard will not detect this kind of issue.

According to the i.MX Reference Manual, the RSTT bit (SYS_CTRL[28]) is designed to reset the tuning circuit. While the Reference Manual states that clearing EXECUTE_TUNING bit from 1 to 0 in AUTOCMD12_ERR_STATUS can also set RSTT, this mechanism only works when the original EXECUTE_TUNING bit was 1. When the bit is already 0, the tuning circuit reset will not be triggered. This explicit reset approach strengthens the tuning reliability and aligns with the Reference Manual recommendations.

2025-05-14mmc: mtk-sd: Aggregate R/W for top_base iospace case where possibleAngeloGioacchino Del Regno
In case the controller uses the top_base iospace, most register read/writes can be changed from multiple RWs to a single read and a single write. Where possible, and where it makes sense, aggregate the multiple reads and writes to just one.

2025-05-14mmc: mtk-sd: Aggregate writes for MSDC_PATCH_BIT1/2 setupAngeloGioacchino Del Regno
Instead of continuously reading and writing to the patch bit 1/2 registers, prepare the final values to write to those and write just once per register during the setup phase. This makes the driver slightly smaller and also slightly improves the execution time of the msdc_init_hw function, called not only at probe time, but also when resuming from system suspend.

2025-05-14mmc: mtk-sd: Clarify patch bit register initialization and layoutAngeloGioacchino Del Regno
In preparation for cleaning up the msdc_init_hw register setting for the patch bit registers, add the necessary definitions for bits in the MSDC_PATCH_BIT and MSDC_PATCH_BIT1 registers and use them in place of "magic numbers" writes during initialization. This commit brings no functional differences.
