Merge branch 'for-4.15' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata
Pull libata updates from Tejun Heo: "Nothing too interesting or alarming. Other than a new power saving mode addition to ahci and crash fix on a tracepoint, all changes are trivial or device-specific" * 'for-4.15' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata: (22 commits) ahci: imx: Handle increased read failures for IMX53 temperature sensor in low frequency mode. ata: sata_dwc_460ex: Propagate platform device ID to DMA driver ata: fixes kernel crash while tracing ata_eh_link_autopsy event ata: pata_pdc2027x: Fix space before '[' error. libata: fix spelling mistake: 'ambigious' -> 'ambiguous' ata: ceva: Add SMMU support for SATA IP ata: ceva: Correct the suspend and resume logic for SATA ata: ceva: Correct the AXI bus configuration for SATA ports ata: ceva: Add CCI support for SATA if CCI is enabled ata: ceva: Make RxWaterMark value as module parameter ata: ceva: Disable Device Sleep capability ata: ceva: Add gen 3 mode support in driver ata: ceva: Move sata port phy oob settings to device-tree devicetree: bindings: Add sata port phy config parameters in ahci-ceva ata: mark expected switch fall-throughs ata: sata_mv: remove a redundant assignment to pointer ehi ahci: Add support for Cavium's fifth generation SATA controller ata: sata_rcar: Use of_device_get_match_data() helper libata: make ata_port_type const libata: make static arrays const, reduces object code size ...
