2017-05-23arm64: dts: hi6220: Move board data from the dwmmc nodes to hikey dtsUlf Hansson1-19/+0
Move the board specific descriptions for the dwmmc nodes in the hi6220 SoC dtsi, into the hikey dts as it's there these belongs. While changing this, let's take the opportunity to drop the use of the "ti,non-removable" binding for one of the dwmmc device nodes, as it's not a valid binding and not used. Drop also the unnecessary use of "num-slots = <0x1>" for all of the dwmmc nodes, as there is no need to set this since when default number of slots is one.

2017-05-23arm64: dts: hi6220: Move the fixed_5v_hub regulator to the hikey dtsUlf Hansson1-11/+1
The regulator is a part of the hikey board, therefore let's move it from the hi6220 SoC dtsi file into the hikey dts file . Let's also rename the regulator according to the datasheet (5V_HUB) to better reflect the HW.

The MMC hosts could be left in an unconsistent or uninitialized state from the firmware. Instead of assuming, the firmware did the right things, let's reset the host controllers.

2015-10-06arm64: dts: add all hi6220 uart nodesTyler Baker1-1/+42
This patch adds all UART nodes for the Hi6220 SoC. Recently a board[1] has been developed to standardize UART access across all the 96boards consumer edition boards. To use this hardware on HiKey we must configure and enable UART3. However, to ensure backward compatibility we must keep UART0 enabled as well. I have removed the hard coded clock index values in favor of using the ones already defined in include/dt-bindings/clock/hi6220-clock.h. Since UART0 needs to be soldered, it has been suggested to use the UART3 as the default console. This patch was boot tested on top of next-20150930, with both UART configurations.
