misc: rtsx: usb: Ensure mmc child device is active when card is present

2025-07-16T12:26:39Z

When a card is present in the reader, the driver currently defers autosuspend by returning -EAGAIN during the suspend callback to trigger USB remote wakeup signaling. However, this does not guarantee that the mmc child device has been resumed, which may cause issues if it remains suspended while the card is accessible. This patch ensures that all child devices, including the mmc host controller, are explicitly resumed before returning -EAGAIN. This fixes a corner case introduced by earlier remote wakeup handling, improving reliability of runtime PM when a card is inserted.

misc: rtsx: Add support for RTS5264 Version B and optimize init flow

2025-06-24T15:45:55Z

This patch adds support for the Realtek RTS5264 Version B card reader controller. To support this chip revision, the driver introduces specific initialization logic to handle the hardware requirements of Version B. The probe flow is updated to detect this version and apply the necessary register configurations. Additionally, the initialization sequence for Version B has been optimized to improve robustness and ensure proper device setup during power-on. These changes ensure correct operation and compatibility with systems using RTS5264 Version B.

misc: cardreader: Return -EBUSY if regions are busy

2025-04-25T13:54:08Z

cardreader returns -ENOMEM if a PCI region is currently in use ("requested") by another driver. The proper return code for this is -EBUSY. Replace -ENOMEM with -EBUSY.

misc: cardreader: Use non-hybrid PCI devres API

2025-04-25T13:54:08Z

cardreader 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().

misc: rtsx: Enhance the signal handling processes in SVID/SSID 1028:0CE1 platform

2025-04-15T14:14:37Z

This patch introduces improvements to the signal handling processes on the SVID/SSID 1028:0CE1 platform. By optimizing signal handling processes we aim to deliver a more stable and reliable user experience. The enhancements ensure robust connectivity and enhance signal process performance. We have conducted extensive testing to ensure these modifications result in noticeable improvements without impacting existing functionalities.

Revert "drivers/card_reader/rtsx_usb: Restore interrupt based detection"

2025-02-27T20:24:53Z

This reverts commit 235b630eda072d7e7b102ab346d6b8a2c028a772. This commit was found responsible for issues with SD card recognition, as users had to re-insert their cards in the readers and wait for a while. As for some people the SD card was involved in the boot process it also caused boot failures.

drivers/card_reader/rtsx_usb: Restore interrupt based detection

2025-01-10T14:42:53Z

This commit reintroduces interrupt-based card detection previously used in the rts5139 driver. This functionality was removed in commit 00d8521dcd23 ("staging: remove rts5139 driver code"). Reintroducing this mechanism fixes presence detection for certain card readers, which with the current driver, will taken approximately 20 seconds to enter S3 as `mmc_rescan` has to be frozen.
