1 * HiSilicon SAS controller
3 The HiSilicon SAS controller supports SAS/SATA.
5 Main node required properties:
6 - compatible : value should be as follows:
7 (a) "hisilicon,hip05-sas-v1" for v1 hw in hip05 chipset
8 (b) "hisilicon,hip06-sas-v2" for v2 hw in hip06 chipset
9 (c) "hisilicon,hip07-sas-v2" for v2 hw in hip07 chipset
10 - sas-addr : array of 8 bytes for host SAS address
11 - reg : Address and length of the SAS register
12 - hisilicon,sas-syscon: phandle of syscon used for sas control
13 - ctrl-reset-reg : offset to controller reset register in ctrl reg
14 - ctrl-reset-sts-reg : offset to controller reset status register in ctrl reg
15 - ctrl-clock-ena-reg : offset to controller clock enable register in ctrl reg
16 - queue-count : number of delivery and completion queues in the controller
17 - phy-count : number of phys accessible by the controller
18 - interrupts : For v1 hw: Interrupts for phys, completion queues, and fatal
19 sources; the interrupts are ordered in 3 groups, as follows:
21 - Completion queue interrupts
23 Phy interrupts : Each phy has 3 interrupt sources:
27 The phy interrupts are ordered into groups of 3 per phy
28 (broadcast, phyup, and abnormal) in increasing order.
29 Completion queue interrupts : each completion queue has 1
31 The interrupts are ordered in increasing order.
32 Fatal interrupts : the fatal interrupts are ordered as follows:
35 For v2 hw: Interrupts for phys, Sata, and completion queues;
36 the interrupts are ordered in 3 groups, as follows:
39 - Completion queue interrupts
40 Phy interrupts : Each controller has 2 phy interrupts:
43 Sata interrupts : Each phy on the controller has 1 Sata
44 interrupt. The interrupts are ordered in increasing
46 Completion queue interrupts : each completion queue has 1
47 interrupt source. The interrupts are ordered in
50 Optional main node properties:
51 - hip06-sas-v2-quirk-amt : when set, indicates that the v2 controller has the
52 "am-max-transmissions" limitation.
