   4 Subject: [PATCH] ARM: dts: BCM53573: Describe Tenda AC9 PCIe card in DT
   5 MIME-Version: 1.0
   6 Content-Type: text/plain; charset=UTF-8
   7 Content-Transfer-Encoding: 8bit
   8
   9 Tenda AC9 has PCIe controller with just one device connected to it:
  10 0000:00:00.0            14e4:d145       Bridge Device
  11 └─ 0000:01:00.0             14e4:a8db       Network Controller
  12
  13 This card is directly on SoC (doesn't use physical connector) and has
  14 BCM43217 chipset with bcma bus. One of its components is ChipCommon core
  15 which is also a GPIO controller. We need to describe it to be able to
  16 add devices using its GPIO pins.
