[linux-sunxi] [PATCH 2/2] sunxi: A64: enable USB support

From: Amit Singh Tomar Mostly by adding MACH_SUN50I to some existing #ifdefs enable support for the the HCI0 USB host controller on the A64. Fix up some minor 64-bit hiccups on the way. Add the bare minimum DT bits to the A64 .dtsi and enable the controllers and the PHY on

[linux-sunxi] [PATCH 0/2] arm64: Pine64/A64: USB support

Hi, these two patches enable the first USB host controller on the Pine64 board. This allows to load and boot from USB pen drives inserted into the lower USB socket on the board, for instance. The first patch massages the OHCI driver to compile cleanly for 64-bit. This is admittedly cutting some

[linux-sunxi] [PATCH 1/2] drivers: USB: OHCI: allow compilation for 64-bit targets

OHCI has a known limitation of allowing only 32-bit DMA buffer addresses, so we have a lot of u32 variables around, which are assigned to pointers and vice versa. This obviously creates issues with 64-bit systems, so the compiler complains here and there. To allow compilation for 64-bit boards

[linux-sunxi] [PATCH] arm: dts: Pine64: add Ethernet alias

The sun8i-emac driver works fine with the A64 Ethernet IP, but we are missing an alias entry to trigger the driver instantiation by U-Boot. Add the line to point U-Boot to the Ethernet DT node. This enables TFTP boot on the Pine64. Signed-off-by: Andre Przywara ---

Hi, As it was in the first iteration, this is the A64 support based on the new sunxi-ng clock framework. The support for it is quite minimal at the moment, but it should be fairly easy to add new devices, as most of the design is shared with older SoCs. Let me know what you think, Maxime
