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