35 We have not been able to figure out which bit fields these correspond to
51 - compatible: should be one of:
52 "qcom,msm8660-ebi2"
53 "qcom,apq8060-ebi2"
54 - #address-cells: should be <2>: the first cell is the chipselect,
56 - #size-cells: should be <1>
57 - ranges: should be set to:
64 - reg: two ranges of registers: EBI2 config and XMEM config areas
65 - reg-names: should be "ebi2", "xmem"
66 - clocks: two clocks, EBI_2X and EBI
67 - clock-names: should be "ebi2x", "ebi2"
70 - Nodes inside the EBI2 will be considered device nodes.
77 - qcom,xmem-recovery-cycles: recovery cycles is the time the memory continues to
78 drive the data bus after OE is de-asserted, in order to avoid contention on
79 the data bus. They are inserted when reading one CS and switching to another
80 CS or read followed by write on the same CS. Valid values 0 thru 15. Minimum
82 - qcom,xmem-write-hold-cycles: write hold cycles, these are extra cycles
83 inserted after every write minimum 1. The data out is driven from the time
84 WE is asserted until CS is asserted. With a hold of 1 (value = 0), the CS
86 - qcom,xmem-write-delta-cycles: initial latency for write cycles inserted for
88 - qcom,xmem-read-delta-cycles: initial latency for read cycles inserted for the
90 - qcom,xmem-write-wait-cycles: number of wait cycles for every write access, 0=1
92 - qcom,xmem-read-wait-cycles: number of wait cycles for every read access, 0=1
96 - qcom,xmem-address-hold-enable: this is a boolean property stating that we
99 - qcom,xmem-adv-to-oe-recovery-cycles: the number of cycles elapsed before an OE
102 - qcom,xmem-read-hold-cycles: the length in cycles of the first segment of a
103 read transfer. For a single read transfer this will be the time from CS
