+The GPIO sysfs is deprecated and disabled in the defconfig files.

+add the missing GPIO line names for Raspberry Pi 2 and 3. In the lack
+of full schematics i would leave all undocumented pins as unnamed.

+
+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".

-
-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).
-
-Further 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.)
-
-Without trapping reads to CNTVCT, a userspace program is able to read it
-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 11 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 the smallest
-backward jumps of 2048 cycles observed over 400 times per second on each
-core. (Of course, this is partially due to 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 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

-Tested-by: Andre Przywara <andre.przywara@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 iff the three values are 1) individually unique
-and 2) increasing. This takes at minimum 3 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 (2046/2048 of the time) to a single read by
-simply ignoring values that match the pattern. This still takes no more
-than 3 cycles in the worst case, and requires much less code.
