  The old code for i2c write would break on some controllers, which fails
  at handling Repeated Start Condition. So we will just use i2c_master_send
  to handle write in one transanction.

  Changes since v1:
  - Remove indentation change

• 7ea5fda2b   ptp: ptp_clockmatrix: update to support 4.8.7 firmware ... Browse Code »

  With 4.8.7 firmware, adjtime can change delta instead of absolute time,
  which greately increases snap accuracy. PPS alignment doesn't have to
  be set for every single TOD change. Other minor changes includes:
  adding more debug logs, increasing snap accuracy for pre 4.8.7 firmware
  and supporting new tcs2bin format.

• 3a6ba7dc7   ptp: Add a ptp clock driver for IDT ClockMatrix. ... Browse Code »

  The IDT ClockMatrix (TM) family includes integrated devices that provide
  eight PLL channels. Each PLL channel can be independently configured as a
  frequency synthesizer, jitter attenuator, digitally controlled
  oscillator (DCO), or a digital phase lock loop (DPLL). Typically
  these devices are used as timing references and clock sources for PTP
  applications. This patch adds support for the device.
