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 : Contains two regions. The first is the address and length of the SAS
12 register. The second is the address and length of CPLD register for
13 SGPIO control. The second is optional, and should be set only when
14 we use a CPLD for directly attached disk LED control.
15 - hisilicon,sas-syscon: phandle of syscon used for sas control
16 - ctrl-reset-reg : offset to controller reset register in ctrl reg
17 - ctrl-reset-sts-reg : offset to controller reset status register in ctrl reg
18 - ctrl-clock-ena-reg : offset to controller clock enable register in ctrl reg
19 - queue-count : number of delivery and completion queues in the controller
20 - phy-count : number of phys accessible by the controller
21 - interrupts : For v1 hw: Interrupts for phys, completion queues, and fatal
22 sources; the interrupts are ordered in 3 groups, as follows:
24 - Completion queue interrupts
26 Phy interrupts : Each phy has 3 interrupt sources:
30 The phy interrupts are ordered into groups of 3 per phy
31 (broadcast, phyup, and abnormal) in increasing order.
32 Completion queue interrupts : each completion queue has 1
34 The interrupts are ordered in increasing order.
35 Fatal interrupts : the fatal interrupts are ordered as follows:
38 For v2 hw: Interrupts for phys, Sata, and completion queues;
39 the interrupts are ordered in 3 groups, as follows:
42 - Completion queue interrupts
43 Phy interrupts : Each controller has 2 phy interrupts:
46 Sata interrupts : Each phy on the controller has 1 Sata
47 interrupt. The interrupts are ordered in increasing
49 Completion queue interrupts : each completion queue has 1
50 interrupt source. The interrupts are ordered in
53 Optional main node properties:
54 - hip06-sas-v2-quirk-amt : when set, indicates that the v2 controller has the
55 "am-max-transmissions" limitation.
56 - hisilicon,signal-attenuation : array of 3 32-bit values, containing de-emphasis,
57 preshoot, and boost attenuation readings for the board. They
58 are used to describe the signal attenuation of the board. These
59 values' range is 7600 to 12400, and used to represent -24dB to
61 The formula is "y = (x-10000)/10000". For example, 10478
