   4 Subject: [PATCH 202/232] Add overlay and enable support for QCA7000 board
   5
   6 This adds a device tree overlay for the QCA7000 which can be used
   7 when attaching an I2SE's PLC Stamp micro EVK to the Raspberry Pi.
   8
   9 This Evaluation Board embeds a QCA7000 chip, a Homeplug Green PHY
  10 powerline chip from Qualcomm/Atheros for the Internet of Things.
  11
  12 This patch also enables the required QCA7000 driver module
  13 in the default configurations.
