9 - compatible: Armada 370/XP SoC are supported using the
10 "marvell,mvebu-devbus" compatible string.
13 "marvell,orion-devbus" compatible string.
15 - reg: A resource specifier for the register space.
20 - #address-cells: Must be set to 1
21 - #size-cells: Must be set to 1
22 - ranges: Must be set up to reflect the memory layout with four
23 integer values for each chip-select line in use:
28 - devbus,keep-config This property can optionally be used to keep
37 - devbus,turn-off-ps: Defines the time during which the controller does not
41 Mandatory, except if devbus,keep-config is used.
43 - devbus,bus-width: Defines the bus width, in bits (e.g. <16>).
44 Mandatory, except if devbus,keep-config is used.
46 - devbus,badr-skew-ps: Defines the time delay from from A[2:0] toggle,
50 Mandatory, except if devbus,keep-config is used.
52 - devbus,acc-first-ps: Defines the time delay from the negation of
55 Mandatory, except if devbus,keep-config is used.
57 - devbus,acc-next-ps: Defines the time delay between the cycle that
60 Mandatory, except if devbus,keep-config is used.
62 - devbus,rd-setup-ps: Defines the time delay between DEV_CSn assertion to
63 DEV_OEn assertion. If set to 0 (default),
65 This parameter has no affect on <acc-first-ps> parameter
66 (no affect on first data sample). Set <rd-setup-ps>
67 to a value smaller than <acc-first-ps>.
68 Mandatory for "marvell,mvebu-devbus" compatible string,
69 except if devbus,keep-config is used.
71 - devbus,rd-hold-ps: Defines the time between the last data sample to the
72 de-assertion of DEV_CSn. If set to 0 (default),
73 DEV_OEn and DEV_CSn are de-asserted at the same cycle
75 This parameter has no affect on DEV_OEn de-assertion.
76 DEV_OEn is always de-asserted the next cycle after
78 affect on <turn-off-ps> parameter.
79 Set <rd-hold-ps> to a value smaller than <turn-off-ps>.
80 Mandatory for "marvell,mvebu-devbus" compatible string,
81 except if devbus,keep-config is used.
85 - devbus,ale-wr-ps: Defines the time delay from the ALE[0] negation cycle
86 to the DEV_WEn assertion.
89 - devbus,wr-low-ps: Defines the time during which DEV_WEn is active.
95 - devbus,wr-high-ps: Defines the time during which DEV_WEn is kept
98 <wr-high-ps> - <tick> ps.
103 - devbus,sync-enable: Synchronous device enable.
106 Mandatory for "marvell,mvebu-devbus" compatible string,
107 except if devbus,keep-config is used.
