Subject: [PATCH] ARM: DTS: rk3288-tinker: Enabling SDIO and Wifi
|
|
|
|
Adding the appropriate nodes in order to exploit the WiFi capabilities
|
|
of the board.
|
|
Since these capabilities are provided through SDIO, and the SDIO
|
|
nodes were not defined, these were added too.
|
|
|
|
These seems to depend on each other so they are added in one big
|
|
patch.
|
|
|
|
Split if necessary.
