Merge tag 'ata-6.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dlemoal/libata
Pull ata updates from Damien Le Moal: - Add support for the .remove_new callback to the ata_platform code to simplify device removal interface (Uwe) - Code simplification in ata_dev_revalidate() (Yahu) - Fix code indentation and coding style in the pata_parport protocol modules to avoid warnings from static code analyzers (me) - Clarify ata_eh_qc_retry() behavior with better comments (Niklas) - Simplify and improve ata_change_queue_depth() behavior to have a consistent behavior between libsas managed devices and libata managed devices (e.g. AHCI connected devices) (me) - Cleanup libata-scsi and libata-eh code to use the ata_ncq_enabled() and ata_ncq_supported() helpers instead of open coding flags tests (me) - Cleanup ahci_reset_controller() code (me) - Change the pata_octeon_cf and sata_svw drivers to use of_property_read_reg() to simplify the code (Rob, me) - Remove unnecessary include files from ahci_octeon driver (me) - Modify the DesignWare ahci dt bindings to add support for the Rockchip RK3588 AHCI (Sebastian) * tag 'ata-6.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dlemoal/libata: (29 commits) dt-bindings: phy: rockchip: rk3588 has two reset lines dt-bindings: ata: dwc-ahci: add Rockchip RK3588 dt-bindings: ata: dwc-ahci: add PHY clocks ata: ahci_octeon: Remove unnecessary include ata: pata_octeon_cf: Add missing header include ata: ahci: Cleanup ahci_reset_controller() ata: Use of_property_read_reg() to parse "reg" ata: libata-scsi: Use ata_ncq_supported in ata_scsi_dev_config() ata: libata-eh: Use ata_ncq_enabled() in ata_eh_speed_down() ata: libata-sata: Improve ata_change_queue_depth() ata: libata-sata: Simplify ata_change_queue_depth() ata: libata-eh: Clarify ata_eh_qc_retry() behavior at call site ata: pata_parport: Fix on26 module code indentation and style ata: pata_parport: Fix on20 module code indentation and style ata: pata_parport: Fix ktti module code indentation and style ata: pata_parport: Fix kbic module code indentation and style ata: pata_parport: Fix friq module code indentation and style ata: pata_parport: Fix fit3 module code indentation and style ata: pata_parport: Fix fit2 module code indentation and style ata: pata_parport: Fix epia module code indentation and style ...
