7 title: Synopsys DWC AHCI SATA controller properties
10 - Serge Semin <fancer.lancer@gmail.com>
13 This document defines device tree schema for the generic Synopsys DWC
14 AHCI controller properties.
19 - $ref: ahci-common.yaml#
30 Basic DWC AHCI SATA clock sources like application AXI/AHB BIU clock,
31 PM-alive clock, RxOOB detection clock, embedded PHYs reference (Rx/Tx)
41 - description: Application APB/AHB/AXI BIU clock
47 - description: Power Module keep-alive clock
49 - description: RxOOB detection clock
51 - description: SATA Ports reference clock
56 At least basic application and reference clock domains resets are
57 normally supported by the DWC AHCI SATA controller.
