1 * Cadence Quad SPI controller
4 - compatible : Should be "cdns,qspi-nor".
5 - reg : Contains two entries, each of which is a tuple consisting of a
6 physical address and length. The first entry is the address and
7 length of the controller register set. The second entry is the
8 address and length of the QSPI Controller data area.
9 - interrupts : Unit interrupt specifier for the controller interrupt.
10 - clocks : phandle to the Quad SPI clock.
11 - cdns,fifo-depth : Size of the data FIFO in words.
12 - cdns,fifo-width : Bus width of the data FIFO in bytes.
13 - cdns,trigger-address : 32-bit indirect AHB trigger address.
16 - cdns,is-decoded-cs : Flag to indicate whether decoder is used or not.
19 Subnodes of the Cadence Quad SPI controller are spi slave nodes with additional
21 - cdns,read-delay : Delay for read capture logic, in clock cycles
22 - cdns,tshsl-ns : Delay in nanoseconds for the length that the master
23 mode chip select outputs are de-asserted between
25 - cdns,tsd2d-ns : Delay in nanoseconds between one chip select being
26 de-activated and the activation of another.
27 - cdns,tchsh-ns : Delay in nanoseconds between last bit of current
28 transaction and deasserting the device chip select
30 - cdns,tslch-ns : Delay in nanoseconds between setting qspi_n_ss_out low
31 and first bit transfer.
