include/dt-bindings: Sync some files with the kernel
This commit syncs the dt-bindings/input/* headers with the kernel (v4.5)
and adds dt-bindings/clock/sun4i-a10-pll2.h, both are necessary for newer

sunxi: A23: Fix some revisions needing a different magic sram poke
I've had this one a23 tablet which would not boot and I've finally
figured out what the problem is by looking at the released boot0 code,
it seems the magic sram controller poke which we need to do in s_init()
depends on the revision of the a23.
Specifically this change is needed to get the A23 SoC I have with the
following serial to boot: "E6071AB 26Y7".

ARM: uniphier: switch to raw U-Boot image
Now everything is done to load a raw U-Boot proper image instead of
an mkimage-processed one (as far as I tested on NAND, eMMC, NOR).
The SPL already knows the load address of the U-Boot proper without
parsing its uImage header because the load address is defined by
CONFIG_SYS_TEXT_BASE, assuming that the two images are generated from
the same build.
My main motivation of this switch is to use u-boot-with-spl.bin, a
concatenation of u-boot-spl.bin and u-boot.bin. (I wish there were
a concatenation of u-boot-spl.bin and u-boot.img...) Anyway, this
commit would be useful for one-shot image burn.

ARM: uniphier: support Debug UART
For ARM32 architecture, CONFIG_DEBUG_LL is available for early
low-level debugging (and actually UniPhier 32bit SoCs use it), but
ARM64 architecture does not support it. Instead, CONFIG_DEBUG_UART
is available as an architecture-independent debug facility.
This commit supports it on all the UniPhier SoCs (including the new
ARMv8 SoCs), which is very useful for new SoC bringups.

The System Control block moved to a completely different register

These commands are not necessarily needed for usual operations
(they are useful in case of DDR memory trouble), but enabling them
by default would be nice in terms of the compilation test coverage.
They are small enough, so limited impact on the memory footprint.

ARM: uniphier: add work-around to support Micro Support Card v3.6.10
Due to some hardware guy's awful work, this version is not compatible
with v3.6: the logic of BIT(0) of the reset logic is inverted! (and
v3.6.10 is horribly wrong in multiple ways), but this is what we have
to solve now.
The v3.6 expects 0x0000 set to the register for reset de-assertion,
while v3.6 does 0x0001.
This commit (ab)uses another bug of v3.6.10 to work around the issue.
The UniPhier System Bus is a 16-bit bus, which this support card is
connected to. A 32-bit write to the bus (writel() function call) is
divided into two 16-bit write transactions, with LSB the first. What
is amazing for v3.6.10 is that access to address 4N + 2 goes to 4N
(Jesus Christ!).
For clarification, things are like this:
writel(0x00010000, MICRO_SUPPORT_CARD_RESET);
is done with two bus transactions as follows
[1] write 0x0000 to address MICRO_SUPPORT_CARD
[2] write 0x0001 to address MICRO_SUPPORT_CARD + 2
For v3.6, [1] is written to the register and [2] is correctly ignored
because there is nothing at the address MICRO_SUPPORT_CARD + 2. This
is what we expect.
For v3.6.10, [1] is written to the reset register and then [2] is
over-written to the same register due to the bus access bug.
For the latter, it produces a glitch signal to the BIT[0], so the
device state is lost due to the reset pulse. This solution only
works for the start-up code.
