      drivers/rtc/rtc-armada38x: add a new RTC driver for recent mvebu SoCs · a3a42806
      Gregory CLEMENT 提交于
      The new mvebu SoCs come with a new RTC driver. This patch adds the
      support for this new IP which is currently found in the Armada 38x
      SoCs.
      
      This RTC provides two alarms, but only the first one is used in the
      driver. The RTC also allows using periodic interrupts.

      rtc: rtc-ab-b5ze-s3: add sub-minute alarm support · c8a1d8a5
      Arnaud Ebalard 提交于
      Abracon AB-RTCMC-32.768kHz-B5ZE-S3 alarm is only accurate to the minute.
      For that reason, UIE mode is currently not supported by the driver.  But
      the device provides a watchdog timer which can be coupled with the alarm
      mechanism to extend support and provide sub-minute alarm capability.
      
      This patch implements that extension.  More precisely, it makes use of the
      watchdog timer for alarms which are less that four minutes in the future
      (with second accuracy) and use standard alarm mechanism for other alarms
      (with minute accuracy).

      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
      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.

      drivers/rtc/rtc-rk808.c: fix rtc time reading issue · c412c603
      Chris Zhong 提交于
      After we set the GET_TIME bit, the rtc time can't be read immediately.  We
      should wait up to 31.25 us, about one cycle of 32khz.  Otherwise reading
      RTC time will return a old time.  If we clear the GET_TIME bit after
      setting, the time of i2c transfer is certainly more than 31.25us.
      
      Doug said:
      
      : I think we are safe.  At 400kHz (the max speed of this part) each bit can
      : be transferred no faster than 2.5us.  In order to do a valid i2c
      : transaction we need to _at least_ write the address of the device and the
      : data onto the bus, which is 16 bits.  16 * 2.5us = 40us.  That's above the
      : 31.25us

      ARM: mvebu: ISL12057 rtc chip can now wake up RN102, RN102 and RN2120 · 1a67e256
      Arnaud Ebalard 提交于
      Now that alarm support for ISL12057 chip is available w/ the specific
      "isil,irq2-can-wakeup-machine" property, let's use that feature of the
      driver dedicated to NETGEAR ReadyNAS 102, 104 and 2120 specific routing of
      RTC Alarm IRQ#2 pin; on those devices, this pin is not connected to the
      SoC but to a PMIC, which allows the device to be powered up when RTC alarm
      rings.
      
      For that to work, the chip needs to be explicitly marked as a device
      wakeup source using this "isil,irq2-can-wakeup-machine" boolean property.
      This makes 'wakealarm' sysfs entry available to configure the alarm.
