Subject: [PATCH] net: stmmac: snps, dwmac-mdio MDIOs are automatically
registered
stmmac bindings docs said that its mdio node must have
compatible = "snps,dwmac-mdio";
Since dwmac-sun8i does not have any good reasons to not doing it, all
their MDIO node must have it.
Since these compatible is automatically registered, dwmac-sun8i compatible
does not need to be in need_mdio_ids.

Subject: [PATCH] net: stmmac: dwmac-sun8i: Handle integrated/external MDIOs
The Allwinner H3 SoC have two distinct MDIO bus, only one could be
active at the same time.
The selection of the active MDIO bus are done via some bits in the EMAC
register of the system controller.
This patch implement this MDIO switch via a custom MDIO-mux.

Subject: [PATCH] net: stmmac: sun8i: Restore the compatibles
The original dwmac-sun8i DT bindings have some issue on how to handle
integrated PHY and was reverted in last RC of 4.13.
But now we have a solution so we need to get back that was reverted.
This patch restore compatibles about dwmac-sun8i
This reverts commit ad4540cc5aa3 ("net: stmmac: sun8i: Remove the compatibles")

Subject: net: stmmac: dwmac-sun8i: fix allwinner,leds-active-low handling
The driver expect "allwinner,leds-active-low" to be in PHY node, but
the binding doc expect it to be in MAC node.
Since all board DT use it also in MAC node, the driver need to search
allwinner,leds-active-low in MAC node.

Subject: [PATCH] ARM: dts: sunxi: Restore EMAC changes (boards)
The original dwmac-sun8i DT bindings have some issue on how to handle
integrated PHY and was reverted in last RC of 4.13.
But now we have a solution so we need to get back that was reverted.
This patch restore all boards DT about dwmac-sun8i
This reverts partially commit fe45174b72ae ("arm: dts: sunxi: Revert EMAC changes")

Subject: [PATCH] ARM: dts: sunxi: h3/h5: represent the mdio switch used by
sun8i-h3-emac
Since dwmac-sun8i could use either an integrated PHY or an external PHY
(which could be at same MDIO address), we need to represent this selection
by a MDIO switch.

Subject: [PATCH] arm64: dts: allwinner: add snps,dwmac-mdio compatible to
emac/mdio
stmmac bindings docs said that its mdio node must have
compatible = "snps,dwmac-mdio";
Since dwmac-sun8i does not have any good reasons to not doing it, all
their MDIO node must have it.

Subject: [PATCH] arm64: dts: allwinner: H5: Restore EMAC changes
The original dwmac-sun8i DT bindings have some issue on how to handle
integrated PHY and was reverted in last RC of 4.13.
But now we have a solution so we need to get back that was reverted.
This patch restore arm64 DT about dwmac-sun8i for H5
This reverts a part of commit 87e1f5e8bb4b ("arm64: dts: allwinner: Revert EMAC changes")

counter
As we are about to use the physical counter on arm64 systems that have
KVM support, implement arch_counter_get_cntpct() and the associated
errata workaround functionality for stable timer reads.

Add a watchdog node for the A64, automatically enabled on all boards.
Since the device is compatible with an existing driver, we only reserve
a new compatible string to be used together with the fall back.
Tested on Olimex Teres-I.

The A64 SPI controllers are register compatible to the h3/h5 SPI
controllers.
The A64 has two SPI controllers, each with a single chip select.
The handles for the DMA channels (23/24 for SPI0/SPI1) are omitted,
as the A64 DMA support is currently missing.

Subject: [PATCH] clocksource/drivers/arch_timer: Workaround for Allwinner A64
timer instability
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The Allwinner A64 SoC is known[1] to have an unstable architectural
timer, which manifests itself most obviously in the time jumping forward
a multiple of 95 years[2][3]. This coincides with 2^56 cycles at a
timer frequency of 24 MHz, implying that the time went slightly backward
(and this was interpreted by the kernel as it jumping forward and
wrapping around past the epoch).
Investigation revealed instability in the low bits of CNTVCT at the
point a high bit rolls over. This leads to power-of-two cycle forward
and backward jumps. (Testing shows that forward jumps are about twice as
likely as backward jumps.) Since the counter value returns to normal
after an indeterminate read, each "jump" really consists of both a
forward and backward jump from the software perspective.
Unless the kernel is trapping CNTVCT reads, a userspace program is able
to read the register in a loop faster than it changes. A test program
running on all 4 CPU cores that reported jumps larger than 100 ms was
run for 13.6 hours and reported the following:
Count | Event
-------+---------------------------
9940 | jumped backward 699ms
268 | jumped backward 1398ms
1 | jumped backward 2097ms
16020 | jumped forward 175ms
6443 | jumped forward 699ms
2976 | jumped forward 1398ms
9 | jumped forward 356516ms
9 | jumped forward 357215ms
4 | jumped forward 714430ms
1 | jumped forward 3578440ms
This works out to a jump larger than 100 ms about every 5.5 seconds on
each CPU core.
The largest jump (almost an hour!) was the following sequence of reads:
0x0000007fffffffff → 0x00000093feffffff → 0x0000008000000000
Note that the middle bits don't necessarily all read as all zeroes or
all ones during the anomalous behavior; however the low 10 bits checked
by the function in this patch have never been observed with any other
value.
Also note that smaller jumps are much more common, with backward jumps
of 2048 (2^11) cycles observed over 400 times per second on each core.
(Of course, this is partially explained by lower bits rolling over more
frequently.) Any one of these could have caused the 95 year time skip.
Similar anomalies were observed while reading CNTPCT (after patching the
kernel to allow reads from userspace). However, the CNTPCT jumps are
much less frequent, and only small jumps were observed. The same program
as before (except now reading CNTPCT) observed after 72 hours:
Count | Event
-------+---------------------------
17 | jumped backward 699ms
52 | jumped forward 175ms
2831 | jumped forward 699ms
5 | jumped forward 1398ms
Further investigation showed that the instability in CNTPCT/CNTVCT also
affected the respective timer's TVAL register. The following values were
observed immediately after writing CNVT_TVAL to 0x10000000:
CNTVCT | CNTV_TVAL | CNTV_CVAL | CNTV_TVAL Error
--------------------+------------+--------------------+-----------------
0x000000d4a2d8bfff | 0x10003fff | 0x000000d4b2d8bfff | +0x00004000
0x000000d4a2d94000 | 0x0fffffff | 0x000000d4b2d97fff | -0x00004000
0x000000d4a2d97fff | 0x10003fff | 0x000000d4b2d97fff | +0x00004000
0x000000d4a2d9c000 | 0x0fffffff | 0x000000d4b2d9ffff | -0x00004000
The pattern of errors in CNTV_TVAL seemed to depend on exactly which
value was written to it. For example, after writing 0x10101010:
CNTVCT | CNTV_TVAL | CNTV_CVAL | CNTV_TVAL Error
--------------------+------------+--------------------+-----------------
0x000001ac3effffff | 0x1110100f | 0x000001ac4f10100f | +0x1000000
0x000001ac40000000 | 0x1010100f | 0x000001ac5110100f | -0x1000000
0x000001ac58ffffff | 0x1110100f | 0x000001ac6910100f | +0x1000000
0x000001ac66000000 | 0x1010100f | 0x000001ac7710100f | -0x1000000
0x000001ac6affffff | 0x1110100f | 0x000001ac7b10100f | +0x1000000
0x000001ac6e000000 | 0x1010100f | 0x000001ac7f10100f | -0x1000000
I was also twice able to reproduce the issue covered by Allwinner's
workaround[4], that writing to TVAL sometimes fails, and both CVAL and
TVAL are left with entirely bogus values. One was the following values:
CNTVCT | CNTV_TVAL | CNTV_CVAL
--------------------+------------+--------------------------------------
0x000000d4a2d6014c | 0x8fbd5721 | 0x000000d132935fff (615s in the past)
Reviewed-by: Marc Zyngier <marc.zyngier@arm.com>
========================================================================
Because the CPU can read the CNTPCT/CNTVCT registers faster than they
change, performing two reads of the register and comparing the high bits
(like other workarounds) is not a workable solution. And because the
timer can jump both forward and backward, no pair of reads can
distinguish a good value from a bad one. The only way to guarantee a
good value from consecutive reads would be to read _three_ times, and
take the middle value only if the three values are 1) each unique and
2) increasing. This takes at minimum 3 counter cycles (125 ns), or more
if an anomaly is detected.
However, since there is a distinct pattern to the bad values, we can
optimize the common case (1022/1024 of the time) to a single read by
simply ignoring values that match the error pattern. This still takes no
more than 3 cycles in the worst case, and requires much less code. As an
additional safety check, we still limit the loop iteration to the number
of max-frequency (1.2 GHz) CPU cycles in three 24 MHz counter periods.
For the TVAL registers, the simple solution is to not use them. Instead,
read or write the CVAL and calculate the TVAL value in software.
Although the manufacturer is aware of at least part of the erratum[4],
there is no official name for it. For now, use the kernel-internal name
"UNKNOWN1".

Subject: [PATCH] ARM: dts: sun8i: fix USB Ethernet of Orange Pi R1
Orange Pi R1 uses a Realtek RTL8152B USB Ethernet chip, which is easily
seen on the board but not show in the schematics. A regulator for the
power of the RTL8152B chip is hidden, which uses the same pin with the
Wi-Fi regulator on the original Orange Pi Zero.
Add this regulator back to the device tree, and bind it to USB1.
