• f4d862237   spi/bcm63xx-hsspi: add support for dual spi read/write ... Browse Code »

  Add support for dual read/writes on spi-bcm63xx-hsspi. This has been
  tested with a s25fl129p1 dual read capable spi flash, with a nice speed
  improvement:

  serial read:

  root@OpenWrt:/# time dd if=/dev/mtd4 of=/dev/null bs=8192
  2032+0 records in
  2032+0 records out
  real 0m 4.39s
  user 0m 0.00s
  sys 0m 1.55s

  dual read:

  root@OpenWrt:/# time dd if=/dev/mtd4 of=/dev/null bs=8192
  2032+0 records in
  2032+0 records out
  real 0m 3.09s
  user 0m 0.00s
  sys 0m 1.56s

  Calling init_completion() once is enough.

  devm_request_and_ioremap() returns NULL on error, it doesn't return an
  ERR_PTR(). This patch fixes it by switching to devm_ioremap_resource()
  which is the prefered function anyway.
