Subject: soc: sunxi: export a regmap for EMAC clock reg on A64
The A64 SRAM controller memory zone has a EMAC clock register, which is
needed by the Ethernet MAC driver (dwmac-sun8i).
Export a regmap for this register on A64.

Subject: soc: sunxi: sram: Add updated compatible string for A64 system
control
The SRAM mapping controls on Allwinner SoCs is located in a block called
"System Controls". This block also has registers for identifying the SoC,
reading the state of an external boot-related pin, and on some newer SoCs,
glue layer controls for the EMAC Ethernet controller.
The A64 variant compatible is renamed to "allwinner,a64-system-control"
to reflect this. The old A64 compatible is deprecated. So far we haven't
seen any actual use of it.

This introduces support for the SRAM C1 section, that is controlled by
the system controller. This SRAM area can be muxed either to the CPU
or the Video Engine, that needs this area to store various tables (e.g.
the Huffman VLD decoding tables).
This only supports devices with the same layout as the A10 (which also
includes the A13, A20, A33 and other SoCs).

Subject: clk: sunxi-ng: add A64 compatible string
As claiming Allwinner A64 SRAM C is a prerequisite for all sub-blocks of
the A64 DE2, not only the CCU sub-block, a bus driver is then written for
enabling the access to the whole DE2 part by claiming the SRAM.
In this situation, the A64 compatible string will be just added with no
other requirments, as they're processed by the parent bus driver.

Subject: [PATCH 04/16] arm64: dts: allwinner: a64: Add PWM controllers
The Allwinner A64 SoC features two PWM controllers, which are fully
compatible to the one used in the A13 and H3 chips.
Add the nodes for the devices (one for the "normal" PWM, the other for
the one in the CPUS domain) and the pins their outputs are connected to.
On the A64 the "normal" PWM is muxed together with one of the MDIO pins
used to communicate with the Ethernet PHY, so it won't be usable on many
boards. But the Pinebook laptop uses this pin for controlling the LCD
backlight.
On Pine64 the CPUS PWM pin however is routed to the "RPi2" header,
at the same location as the PWM pin on the RaspberryPi.
Tested on Pinebook and Teres-I
[vasily: fixed comment message as requested by Stefan Bruens, added default
muxing options to pwm and r_pwm nodes]

Subject: [PATCH 05/16] arm64: dts: allwinner: add support for Pinebook
Pinebook is a A64-based laptop produced by Pine64, with the following
peripherals:
USB:
- Two external USB ports (one is directly connected to A64's OTG
controller, the other is under a internal hub connected to the host-only
controller.)
- USB HID keyboard and touchpad connected to the internal hub.
- USB UVC camera connected to the internal hub.
Power-related:
- A DC IN jack connected to AXP803's DCIN pin.
- A Li-Polymer battery connected to AXP803's battery pins.
Storage:
- An eMMC by Foresee on the main board (in the product revision of the
main board it's designed to be switchable).
- An external MicroSD card slot.
Display:
- An eDP LCD panel (1366x768) connected via an ANX6345 RGB-eDP bridge.
- A mini HDMI port.
Misc:
- A Hall sensor designed to detect the status of lid, connected to GPIO PL12.
- A headphone jack connected to the SoC's internal codec.
- A debug UART port muxed with headphone jack.
This commit adds basical support for it.
[vasily: squashed several commits into one, added simplefb node, added usbphy
to ehci0 and ohci0 nodes and other cosmetic changes to dts]

Subject: [PATCH 06/16] arm64: dts: allwinner: a64: add SRAM controller device
tree node
Allwinner A64 has a SRAM controller, and in the device tree currently
we have a syscon node to enable EMAC driver to access the EMAC clock
register. As SRAM controller driver can now export regmap for this
register, replace the syscon node to the SRAM controller device node,
and let EMAC driver to acquire its EMAC clock regmap.

Subject: [PATCH 09/16] arm64: allwinner: a64: allow laptops to wake up from
lid
Currently all ARM kernels will have s2idle enabled if CONFIG_SUSPEND is
present. In this case if the lid is closed, systemd-logind will enter
s2idle mode by default; however there's no possible wakeup source
defined, so the system will enter a forever idle.
Add the lid itself as a wakeup source, thus the system can wakeup when
the lid is opened.

Subject: [PATCH 11/16] arm64: dts: allwinner: a64: add device tree node for
HDMI simplefb
As the U-Boot bootloader now is also capable of initialize the HDMI on
A64 boards, add a simplefb device tree node for accessing the HDMI
framebuffer initialized by the bootloader.

Subject: [PATCH 12/16] arm64: dts: allwinner: a64: add HDMI regulator to all
DTs' simplefb_hdmi
On usual A64 board design the power of HDMI controller is connected to
DLDO1 of the AXP803 PMIC. If this regulator is shut down, the HDMI
output will be blank. Therefore the simplefb driver should keep this
regulator on.
Add the regulator to all currently available A64 boards' simplefb_hdmi
device node, if the board is capable of outputing HDMI.

address-cells/size-cells of dwmac-sun8i
address-cells/size-cells is unnecessary for dwmac-sun8i node.
It was in early days, but since a mdio node is used, it could be
removed.
This patch fix the following DT warning:

Subject: [PATCH 16/16] arm64: dts: allwinner: a64: Add Pine64-LTS device tree
file
The Pine64-LTS is a variant of the Pine64 board, from the software
visible side resembling a SoPine module on a baseboard, though the
board has the SoC and DRAM integrated on one PCB.
Due to this it basically shares the DT with the SoPine baseboard, which
we mimic in our DT by inclucing the boardboard .dts into the new file,
just overwriting the model name.
Having a separate .dts for this seems useful, since we don't know yet if
there are subtle differences between the two. Also the SoC on the LTS
board is technically an "R18" instead of the original "A64", although as
far as we know this is just a relabelled version of the original SoC.
