implementation supports boot into a kernel with only UART console.
|
||||
Other features will be added later.

|

files
|
||||
|
||||
Even though they will be the same for all boards, i2c and uart aliases
|
||||
are supposed to live in the individual board files, to not create
|
||||
aliases for disabled nodes.
|
||||
|
||||
So move the newly added aliases for rk3528 over to the Radxa E20C board,
|
||||
which is the only rk3528 board right now.

Subject: [PATCH] arm64: dts: rockchip: Enable eMMC HS200 mode on Radxa E20C
|
||||
|
||||
eMMC HS200 mode (1.8V I/O) is supported by the MMC host controller on
|
||||
RK3528 and works with the optional on-board eMMC module on Radxa E20C.
|
||||
|
||||
Be explicit about HS200 support in the device tree for Radxa E20C.

|

|

Radxa E20C provides one of its GbE ports through RTL8111H connected to
|
||||
SoC's PCIe controller. Let's enable the controller and the PHY used by
|
||||
it to allow usage of the port.
