• bd16f9ebd   rtc-ds1307: typo fix found by coverity ... Browse Code »

  Fix a typo turned up by a Coverity check: referring to the wrong register,
  which could cause problems with DS1338 RTCs whose oscillators halted.

• c065f35c1   rtc-ds1307 becomes new-style i2c driver ... Browse Code »

  Convert the rtc-ds1307 driver into a "new style" driver.

  Also improve probe() checks: be more correct about switching out of
  AM/PM mode, and issue a (debug) diagnostic when failing due to bogus
  register values.

• be5f59f4b   rtc-ds1307: oscillator restart for ds13{37,38,39,40} ... Browse Code »

  When we find a ds1337 or ds1339 with the oscillator powered off, turn it
  on. If the oscillator fault flag was set, clear it and warn that the clock
  needs to be set.

  David Brownell: Bugfixes; provide corresponding update for ds1338, and the
  core of the fix for ds1340. Use a common warning message ("SET TIME!")
  whenever the clock needs to be set after oscillator fault (or oscillator
  enable, if fault is not a separate status).

• 045e0e85f   rtc-ds1307 cleanups ... Browse Code »

  This updates the rtc-ds1307 driver so that converting it to a "new style"
  driver (driver model, not legacy i2c model) will involve fewer changes.

  - Use pointer to i2c_client almost everywhere, so that it's easy
  to let the i2c core create that object;

  - Avoid using i2c_client.adapter, since that field is redundant and
  thus may go away (same object as i2c_client.dev.parent).

  - Extend type enum to include various RTCs this is expected to
  work with, and include register support for them.

  It also cleans up the support for multiple chip types, and fixes a
  glitch that could appear with an un-initialized RTC.

  Update RTC framework so that drivers can constify their method tables, moving
  them from ".data" to ".rodata". Then update the drivers.

• 1abb0dc92   [PATCH] "RTC-framework" driver for DS1307 and similar RTC chips ... Browse Code »

  This is an "RTC-framework" driver for DS1307 and similar RTC chips,

  It should be a full replacement for the existing ds1337.c driver (using the
  older RTC glue), giving a net increase in the number of RTC chips that work
  out-of-the-box. There's a whole cluster of RTCs that are very similar, but
  the 1337 driver was a bit too picky to work with most of them.

  Still no support for RTC alarm IRQs (on chips that support them).
