* ata: ahci_tegra: call tegra_powergate_power_off only when PM domain is not ↵Sowjanya Komatineni2021-04-121-2/+4
| | | | | | | | | | | | | | present This patch adds check to call legacy power domain API tegra_powergate_power_off() only when PM domain is not present. Fixes: 868ed7311cd8 ("ata: ahci_tegra: Add AHCI support for Tegra186") Reviewed-by: Dmitry Osipenko <digetx@gmail.com> Acked-by: Thierry Reding <treding@nvidia.com> Link: https://lore.kernel.org/r/1617915315-13639-2-git-send-email-skomatineni@nvidia.com Signed-off-by: Sowjanya Komatineni <skomatineni@nvidia.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
* ata: ahci_tegra: Add AHCI support for Tegra186Sowjanya Komatineni2021-04-071-13/+47
| | | | | | | | | | | | | | | | | | This patch adds support for AHCI-compliant Serial ATA controller on Tegra186 SoC. Tegra186 does not have sata-oob reset. Tegra186 SATA_NVOOB register filed COMMA_CNT position and width are different compared to Tegra210 and prior. So, this patch adds a flag has_sata_oob_rst and tegra_ahci_regs to SoC specific strcuture tegra_ahci_soc and updated their implementation accordingly.

* ata: add an extra argument to ahci_platform_get_resources()Kunihiko Hayashi2018-08-221-1/+1
| | | | | | | | | | | | | | | | | Add an extra argument to ahci_platform_get_resources(), that is for the bitmap representing the resource to get in this function. Currently there is no resources to be defined, so all the callers set '0' to the argument.

* ata: ahci_platform: fix owner module reference mismatch for scsi hostAkinobu Mita2015-01-291-2/+9
| | | | | | | | | | | | | | | | | | | The owner module reference of the ahci platform's scsi_host is initialized to libahci_platform's one, because these drivers use a scsi_host_template defined in libahci_platform. So these drivers can be unloaded even if the scsi device is being accessed. This fixes it by pushing the scsi_host_template from libahci_platform to all leaf drivers. The scsi_host_template is passed through a new argument of ahci_platform_init_host().

* ata: ahci_tegra: Read calibration fuseMikko Perttunen2014-08-261-4/+10
| | | | | | | | | | | | | The original version of the driver did not read the SATA calibration fuse to remove the dependency to the fuse driver. The fuse driver is now merged, so add this functionality. The calibration fuse contains a 2-bit value used to pick a set of calibration values for the SATA pad.

* ata: libahci_platform: move port_map parameters into the AHCI structureAntoine Ténart2014-07-301-2/+1
| | | | | | | | | | | | | | This patch moves force_port_map and mask_port_map into the ahci_host_priv structure. This allows to modify them into the AHCI framework. This is needed by the new dt bindings representing ports as the port_map mask is computed automatically. Parameters modifying force_port_map, mask_port_map and flags have been removed from the ahci_platform_init_host() function, and inputs in the ahci_host_priv structure are now directly filed.
