Subject: [PATCH] clk: sunxi: register factors clocks behind composite
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This commit reworks factors clock registration to be done behind a
composite clock. This allows us to additionally add a gate, mux or
divisors, as it will be needed by some future PLLs.

The A20 and A31 SMP code have a different way of bringing up a new core.
This will prevent us from using the same set of smp_operations for the
two SoCs family.

The A20 boards we currently have share the same pins for the i2c
controllers they share. Add them to the DTSI.

Subject: [PATCH] reset: Add Allwinner A31 Reset Controller Driver
The Allwinner A31 has an IP maintaining a few other IPs in the SoC in
reset by default. Among these IPs are the High Speed Timers, hence why
we can't use the regular driver construct, and need to call the
registering function directly during machine initialisation.

The A31 has a reset IP that maintains a few other IPs in reset by

thus need to register the reset driver before initializing the timers so
that the reset timer can use the reset framework.

Subject: [PATCH] ARM: sunxi: Initial support for Allwinner's Security ID fuses
Allwinner has electric fuses (efuse) on their line of chips. This driver
reads those fuses, seeds the kernel entropy and exports them as a sysfs
node.
These fuses are most likely to be programmed at the factory, encoding
things like Chip ID, some sort of serial number, etc. and appear to be
reasonably unique.
While in theory, these should be writeable by the user, it will probably
be inconvenient to do so. Allwinner recommends that a certain input pin,
labeled 'efuse_vddq', be connected to GND. To write these fuses however,
a 2.5 V programming voltage needs to be applied to this pin.
Even so, they can still be used to generate a board-unique mac from,
board unique RSA key and seed the kernel RNG.
On sun7i additional storage is available, this is initially used for an
UEFI BOOT key, Secure JTAG key, HDMI-HDCP key and vendor specific keys.
Currently supported are the following known chips:
Allwinner sun4i (A10)
Allwinner sun5i (A10s, A13)
Allwinner sun7i (A20)

+Description: read-only access to the SID (Security-ID) on current
+ A-series SoC's from Allwinner. Currently supports A10, A10s, A13
+ and A20 CPU's. The earlier A1x series of SoCs exports 16 bytes,
+ whereas the newer A20 SoC exposes 512 bytes split into sections.
+ Besides the 16 bytes of SID, there's also an SJTAG area,
+ HDMI-HDCP key and some custom keys. Below a quick overview, for
+ details see the user manual:
+ 0x000 128 bit root-key (sun[457]i)
+ 0x010 128 bit boot-key (sun7i)
+ 0x020 64 bit security-jtag-key (sun7i)
+ 0x028 16 bit key configuration (sun7i)
+ 0x02b 16 bit custom-vendor-key (sun7i)
+ 0x02c 320 bit low general key (sun7i)
+ 0x040 32 bit read-control access (sun7i)
+ 0x064 224 bit low general key (sun7i)
+ 0x080 2304 bit HDCP-key (sun7i)
+ 0x1a0 768 bit high general key (sun7i)
+Users: any user space application which wants to read the SID on
+ Allwinner's A-series of CPU's.
