      net: dsa: fix filling routing table from OF description · 30303813
      由 Pavel Nakonechny 提交于 
      According to description in 'include/net/dsa.h', in cascade switches
configurations where there are more than one interconnected devices,
'rtable' array in 'dsa_chip_data' structure is used to indicate which
port on this switch should be used to send packets to that are destined
for corresponding switch.

However, dsa_of_setup_routing_table() fills 'rtable' with port numbers
of the _target_ switch, but not current one.

This commit removes redundant devicetree parsing and adds needed port
number as a function argument. So dsa_of_setup_routing_table() now just
looks for target switch number by parsing parent of 'link' device node.

To remove possible misunderstandings with the way of determining target
switch number, a corresponding comment was added to the source code and
to the DSA device tree bindings documentation file.

This was tested on a custom board with two Marvell 88E6095 switches with
following corresponding routing tables: { -1, 10 } and { 8, -1 }.

      Input: sun4i-ts - A10 (sun4i) has a different temperature curve · 91c68a7c
      由 Hans de Goede 提交于 
      Testing has revealed that the temperature in the rtp controller of the A10
(sun4i) SoC has a different curve then on the A13 (sun5i) and later models.

Add a new sun5i-a13-ts compatible to differentiate the newer models and
set the curve based on the compatible string.

The new curve is still not ideal on all A10-s, that seems to have to
do with there being a large spread between different A10-s out there,
the new curve us based on callibration results on 4 completely different
models:
                        raw min raw max temp min temp max stepsize offset
Tong Zhang's hackberry    2402    2680    45.0     80.0    0.125   -255.3
Hansg's Cubieboard        2207    2300    36.0     45.0    0.096   -175.8
Olliver's lime 1 (*):     2258    2537    48.3     87.1    0.139   -265.7
Olliver's lime 2 (*):     2222    2486    46.7     91.7    0.170   -331.0
*) from: http://linux-sunxi.org/Temperature_Calibration

Average all 4:                                             0.133   -257.0
Average without outliers (middle 2):                       0.132   -261.0

Since it is better to slightly overreport the temperature this patch uses
the average of all 4 as curve.

This fixes the temperature reported on the A10 being much higher then
expected.

      rtc: add support for Abracon AB-RTCMC-32.768kHz-B5ZE-S3 I2C RTC chip · 0b2f6228
      由 Arnaud Ebalard 提交于 
      This patch adds support for Abracon AB-RTCMC-32.768kHz-B5ZE-S3
RTC/Calendar module w/ I2C interface.

This support includes RTC time reading and setting, Alarm (1 minute
accuracy) reading and setting, and battery low detection.  The device also
supports frequency adjustment and two timers but those features are
currently not implemented in this driver.  Due to alarm accuracy
limitation (and current lack of timer support in the driver), UIE mode is
not supported.

      of: add vendor prefix for Abracon Corporation · 446810f2
      由 Arnaud Ebalard 提交于 
      This series adds support for Abracon AB-RTCMC-32.768kHz-B5ZE-S3 I2C RTC
chip. Unlike many RTC chips, it includes an internal oscillator which
spares room on the PCB. It also has some interesting features, like
battery low detection (which the driver in this series supports). The
only small "limitation" (mainly due to what RTC subsystem expects from
RTC chips) is the fact that its alarm is accurate to the second. This
series provides a solution (described below) for that limitation using
another mechanism of the chip.

I decided to split support between three different patches for
this v0:

- Patch 1/3: it simply references Abracon Corporation in vendor-prefixes
  documentation file. As Abracon has no NASDAQ ticker symbol; I have
  decided to use "abcn" (I initially started my work w/ "ab" but later
  changed for "abcn" which looked more meaningful)
- Patch 2/3: it adds initial support for the chip and provides the
  ability to read/write time and also read/write alarm. As the alarm
  the chip provides is accurate to the minute, the support provided
  by this patch also has this limitation (e.g. UIE mode is not
  supported).
- Patch 3/3: the chip supports a watchdog timer which can be used to
  extend the alarm mechanism in patch 2/3 in order to provide support
  for alarms under one minute (e.g. support UIE mode). In practice,
  the logic I implemented is to use the watchdog timer for alarms which
  are at most 4 minutes in the future and use the common alarm mechanism
  for alarms which are set to larger values. With that additional patch
  the device fully passes the rtctest.c program.

I decided to split the driver between two patches (2 and 3 of 3) in
order to ease review: patch 2 should be pretty straightforward to read
for someone familiar w/ RTC subsystem. Patch 3 only extends what is in
patch 2 regarding alarms.

      rtc: rtc-isl12057: add isil,irq2-can-wakeup-machine property for in-tree users · 298ff012
      由 Arnaud Ebalard 提交于 
      Current in-tree users of ISL12057 RTC chip (NETGEAR ReadyNAS 102, 104 and
2120) do not have the IRQ#2 pin of the chip (associated w/ the Alarm1
mechanism) connected to their SoC, but to a PMIC (TPS65251 FWIW).  This
specific hardware configuration allows the NAS to wake up when the alarms
rings.

Recently introduced alarm support for ISL12057 relies on the provision of
an "interrupts" property in system .dts file, which previous three users
will never get.  For that reason, alarm support on those devices is not
function.  To support this use case, this patch adds a new DT property for
ISL12057 (isil,irq2-can-wakeup-machine) to indicate that the chip is
capable of waking up the device using its IRQ#2 pin (even though it does
not have its IRQ#2 pin connected directly to the SoC).

This specific configuration was tested on a ReadyNAS 102 by setting an
alarm, powering off the device and see it reboot as expected when the
alarm rang w/:

  # echo `date '+%s' -d '+ 1 minutes'` > /sys/class/rtc/rtc0/wakealarm
  # shutdown -h now

As a side note, the ISL12057 remains in the list of trivial devices,
because the property is not per se required by the device to work but can
help handle system w/ specific requirements.  In exchange, the new feature
is described in details in a specific documentation file.
