   4 Subject: [PATCH] ARM: dts: Make vcio a child of the firmware node
   5
   6 In order to resolve a potential startup order bug, the vcio driver has
   7 been rewritten as a platform driver that depends on a DT node for
   8 its instantiation and to locate the firmware driver.
   9
  10 Add that DT node.
