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