Merge tag 'for-5.14/libata-2021-06-27' of git://git.kernel.dk/linux-block
Pull libata updates from Jens Axboe: "The big change in this round is that we're finally in a position where we can sanely remove the old drivers/ide/ code, as libata covers everything we need by now. This is exciting for two reasons: 1) we delete a lot of legacy code that doesn't really meet the standards we have today, and 2) it enables us to clean up various bits in the block layer that exist only because of the old IDE code. Outside of that, just a few minor fixes here, fixups for warnings, etc" * tag 'for-5.14/libata-2021-06-27' of git://git.kernel.dk/linux-block: (29 commits) ata: rb532_cf: remove redundant codes ide: remove the legacy ide driver m68k: use libata instead of the legacy ide driver ARM: disable CONFIG_IDE in pxa_defconfig ARM: disable CONFIG_IDE in footbridge_defconfig alpha: use libata instead of the legacy ide driver pata_cypress: add a module option to disable BM-DMA ata: pata_macio: Avoid overwriting initialised field in 'pata_macio_sht' ata: pata_serverworks: Avoid overwriting initialised field in 'serverworks_osb4_sht ata: pata_sc1200: sc1200_sht'Avoid overwriting initialised field in ' ata: pata_cs5530: Avoid overwriting initialised field in 'cs5530_sht' ata: pata_cs5520: Avoid overwriting initialised field in 'cs5520_sht' ata: pata_atiixp: Avoid overwriting initialised field in 'atiixp_sht' ata: sata_nv: Do not over-write initialise fields in 'nv_adma_sht' and 'nv_swncq_sht' ata: sata_mv: Do not over-write initialise fields in 'mv6_sht' ata: sata_sil24: Do not over-write initialise fields in 'sil24_sht' ata: ahci: Ensure initialised fields are not overwritten in AHCI_SHT() ata: include: libata: Move fields commonly over-written to separate MACRO ahci: Add support for Dell S140 and later controllers ata: ahci_sunxi: Disable DIPM ...
