+
+Timing properties for child nodes:
Read parameters:
drive the AD bus after the completion of a device read.
This prevents contentions on the Device Bus after a read
cycle from a slow device.
+ Mandatory, except if devbus,keep-config is used.
- - devbus,bus-width: Defines the bus width (e.g. <16>)

+ Mandatory, except if devbus,keep-config is used.
- devbus,badr-skew-ps: Defines the time delay from from A[2:0] toggle,
to read data sample. This parameter is useful for
synchronous pipelined devices, where the address
precedes the read data by one or two cycles.
+ Mandatory, except if devbus,keep-config is used.
- devbus,acc-first-ps: Defines the time delay from the negation of
ALE[0] to the cycle that the first read data is sampled
by the controller.
+ Mandatory, except if devbus,keep-config is used.
- devbus,acc-next-ps: Defines the time delay between the cycle that
samples data N and the cycle that samples data N+1
(in burst accesses).
+ Mandatory, except if devbus,keep-config is used.
- devbus,rd-setup-ps: Defines the time delay between DEV_CSn assertion to
DEV_OEn assertion. If set to 0 (default),
This parameter has no affect on <acc-first-ps> parameter
(no affect on first data sample). Set <rd-setup-ps>
to a value smaller than <acc-first-ps>.
+ Mandatory for "marvell,mvebu-devbus" compatible string,
+ except if devbus,keep-config is used.
- devbus,rd-hold-ps: Defines the time between the last data sample to the
de-assertion of DEV_CSn. If set to 0 (default),
last data sampled. Also this parameter has no
affect on <turn-off-ps> parameter.
Set <rd-hold-ps> to a value smaller than <turn-off-ps>.
+ Mandatory for "marvell,mvebu-devbus" compatible string,
+ except if devbus,keep-config is used.
Write parameters:
- devbus,ale-wr-ps: Defines the time delay from the ALE[0] negation cycle
to the DEV_WEn assertion.
+ Mandatory.
- devbus,wr-low-ps: Defines the time during which DEV_WEn is active.
A[2:0] and Data are kept valid as long as DEV_WEn
is active. This parameter defines the setup time of
address and data to DEV_WEn rise.
+ Mandatory.
- devbus,wr-high-ps: Defines the time during which DEV_WEn is kept
inactive (high) between data beats of a burst write.
<wr-high-ps> - <tick> ps.
This parameter defines the hold time of address and
data after DEV_WEn rise.
+ Mandatory.

1: True
0: False
+ Mandatory for "marvell,mvebu-devbus" compatible string,
