ata: ahci-dwc: Remove not-going-to-be-supported code for Baikal SoC

2026-02-24T14:29:57+00:00

As noticed in the discussion [1] the Baikal SoC and platforms are not going to be finalized, hence remove stale code. Link: https://lore.kernel.org/lkml/22b92ddf-6321-41b5-8073-f9c7064d3432@infradead.org/ [1] Signed-off-by: Andy Shevchenko Acked-by: Rob Herring (Arm) Signed-off-by: Niklas Cassel

Pull ATA updates from Damien Le Moal: - Cleanup IRQ masking in the handling of completed report zones commands (Niklas) - Improve the handling of Thunderbolt attached devices to speed up device removal (Henry) - Several patches to generalize the existing max_sec quirks to facilitates quirking the maximum command size of buggy drives, many of which have recently showed up with the recent increase of the default max_sectors block limit (Niklas) - Cleanup the ahci-platform and sata dt-bindings schema (Rob, Manivannan) - Improve device node scan in the ahci-dwc driver (Krzysztof) - Remove clang W=1 warnings with the ahci-imx and ahci-xgene drivers (Krzysztof) - Fix a long standing potential command starvation situation with non-NCQ commands issued when NCQ commands are on-going (me) - Limit max_sectors to 8191 on the INTEL SSDSC2KG480G8 SSD (Niklas) - Remove Vesa Local Bus (VLB) support in the pata_legacy driver (Ethan) - Simple fixes in the pata_cypress (typo) and pata_ftide010 (timing) drivers (Ethan, Linus W) * tag 'ata-6.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/libata/linux: ata: pata_ftide010: Fix some DMA timings ata: pata_cypress: fix typo in error message ata: pata_legacy: remove VLB support ata: libata-core: Quirk INTEL SSDSC2KG480G8 max_sectors dt-bindings: ata: sata: Document the graph port ata: libata-scsi: avoid Non-NCQ command starvation ata: libata-scsi: refactor ata_scsi_translate() ata: ahci-xgene: Fix Wvoid-pointer-to-enum-cast warning ata: ahci-imx: Fix Wvoid-pointer-to-enum-cast warning ata: ahci-dwc: Simplify with scoped for each OF child loop dt-bindings: ata: ahci-platform: Drop unnecessary select schema ata: libata: Allow more quirks ata: libata: Add libata.force parameter max_sec ata: libata: Add support to parse equal sign in libata.force ata: libata: Change libata.force to use the generic ATA_QUIRK_MAX_SEC quirk ata: libata: Add ata_force_get_fe_for_dev() helper ata: libata: Add ATA_QUIRK_MAX_SEC and convert all device quirks ata: libata: avoid long timeouts on hot-unplugged SATA DAS ata: libata-scsi: Remove superfluous local_irq_save()

dt-bindings: ata: sata: Document the graph port

2026-01-14T10:23:20+00:00

An external connector like M.2 could expose the SATA interface to the plugin cards. So add the graph port to establish link between the SATA port and the connector node. Signed-off-by: Manivannan Sadhasivam Reviewed-by: Rob Herring (Arm) Signed-off-by: Damien Le Moal

dt-bindings: ata: ahci-platform: Drop unnecessary select schema

2026-01-08T08:42:45+00:00

The "select" schema is not necessary. It looks like it is there to prevent matching on "generic-ahci" compatible, but that's not necessary because this is the only place "generic-ahci" compatible is present. Signed-off-by: Rob Herring (Arm) Signed-off-by: Damien Le Moal

dt-bindings: Updates Linus Walleij's mail address

My name is stamped into maintainership for a big slew of DT bindings. Now that it is changing, switch it over to my kernel.org mail address, which will hopefully be stable for the rest of my life.

dt-bindings: ata: snps,dwc-ahci: Allow 'iommus' property

2025-10-23T12:29:41+00:00

The AMD Seattle DWC AHCI is behind an IOMMU and has 1-3 entries, so add the 'iommus' property. There's not a specific compatible, so we can't limit it to Seattle. Signed-off-by: Rob Herring (Arm) Signed-off-by: Niklas Cassel

The "apm,xgene-ahci-v2" compatible has been in use for a long time, but was undocumented. It doesn't require clocks or phys. Remove the "apm,xgene-ahci-pcie" compatible which isn't used anywhere while we're here. Signed-off-by: Rob Herring (Arm) Signed-off-by: Damien Le Moal
