  Can you please check once why do we need pull-up and
  pull-down for NAND pins. The NAND chip will be mounted
  over board itself so board design should take care of
  required pull up and pull downs.

  Also, some of the above pins like gpio52 will be only used
  for LCD so we can remove those pins. Later on, when LCD
  support will be added, we can add those pins.

  Thanks,
  Abhishek

  It seems major diff between DK01 C1 and other variants is
  qpic nand. qpic nand is only available in C1 so do we need
  to disable the nand is base dk04 dtsi and enable it in this
  C1 dts only. same for qpic bam.

  Thanks,
  Abhishek

  Normally we need to disable in base dtsi and enable in
  board dtsi so that base dtsi will always work in all the
  boards. Now If We load the base dtsi in any DK04 board
  other than C1, then nand failure will come.

  We can disable in base dtsi itself.

  Normally spi pins should contains spi protocol related pins
  could you please explain what is the role of host_pin and rst
  pins and which driver will use these.

  From pinmux, it looks like multiple gpio based cs are being
  used so do we need to specify cs-gpios like dk01-c2.

  Mostly because, these are always **weak** pull up/down as defaults
  and should be overridden by the ones in the board (if there).

 C1 - Has QPIC NAND, spi 78b5000-> cs0 -> spi_nor
 C5 - Has QPIC NAND, spi 78b5000-> cs0 -> spi_nor, cs1 -> spi_nand
 C2 - Has QPIC NAND, spi 78b5000-> cs0 -> spi_nor ( Audio board, yet to be posted for pending audio drivers)
 C3 - spi 78b5000-> cs0 -> spi_nor

 So C3 is the board where it is disabled and enabled in the rest. But from a
 readability point, feels better to touch this only in each board specific file.
 So will remove this from the common 04.dtsi and move it to each board file.

 Hmm, qpic nand is not there only on C3 and available in rest
 of dk04-c* variants. So it should work, downstream also
 does it in same way. Anyways, from a readability point, feel that
 better to make these uncommon configurations in each board file
 specifically rather than putting in common file and changing like this.

 hmm, as mentioned in the previous patch, feels better to enable
 it only in the board file specifically and not to touch this here
 and the common dtsi.

 hmm, the additional pins were required for zigbee connected as the
 spidev device. So the right probably is to have the additional
 pins required for the device populated under the spi's child node.

 ok, let me check.
