Hello, all In ACPI spec 3.0, section 9.9 defines 4 objects for PATA/SATA: _GTM and _STM are PATA-only objects, which are used to get/set PATA timing information(i.e. PIO and DMA speed); _SDD is SATA-only object, which is used to inform the platform of the type of device attached to a port; _GTF is for both PATA and SATA, which is used to return ATA task file needed to re-init the drive In this patch set, ata_acpi_get_timing() is for getting PATA timing information; ata_acpi_push_timing() is for setting PATA timing information; ata_acpi_push_id() is for operating on _SDD; ata_acpi_exec_tfs() is for getting ATA task file from _GTF and executing them for a given drive NOTE: ata_acpi_get_timing() and ata_acpi_push_timing() are channel (port)-level operations, which have more suitable invocation place in Tejun's upcoming PM patch. So I would not bother to reference(invoke) them in this version of patches and will send out updated patches after Tejun's PM patch is merged into #upstream. Randy, I'll add your sign-off line after you review the patch.
