* Improve ASUS Tinker Board support for 5.10 Remove patches which are unnecessary. Revert DMA for UART as it seems to cause more problems (its also what Armbian is doing). With that Bluetooth firmware seems to load without errors when loaded before the bluetooth daemon is running! Note: It seems that the board overheats quite quickly. With Armbian, without load, that seems not to be a big deal, but HAOS does quite a bunch at startup, leading the CPU to reach the 90°C trip point. Maybe it was related to the rather closed shelf I have the ASUS Tinker board running, but only after using a fan the board behaved for me. * Use hardware flow control explicitly The rtk_hciattach program uses hardware flow control by default (judging from tty settings after starting the program). Just to be sure, explicitly request 115200 and hardware flow control.

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.
