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.

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.

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: h3/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.

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.

||||
|
||||
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")

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

||||

|
||||
|
||||
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)
|
||||

|
||||
|
||||
========================================================================
|
||||
|
||||
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".
