   4 Subject: [PATCH 270/304] ARM: bcm2835: clarify RASPBERRYPI_FIRMWARE dependency
   5
   6 The firmware driver can be a loadable module, but the power domain
   7 can only be built-in, so we get a build error in an allmodconfig
   8 kernel:
   9
  10 :(.text+0x17e59c): undefined reference to `rpi_firmware_property'
  11 :(.text+0x17e51c): undefined reference to `rpi_firmware_get'
  12 :(.text+0x17e244): undefined reference to `rpi_firmware_property'
  13
  14 This changes the dependency to only allow the power domain code
  15 to be enabled when the firmware driver is built-in. Other users
  16 of the firmware driver may still be loadable modules and not
  17 everyone needs the power domains, so we don't change the firmware
  18 code.
