dt-bindings: rtc: update stm32-rtc documentation for stm32mp1 rtc

2018-05-22T18:10:53+00:00

RTC embedded in stm32mp1 SoC is slightly different from stm32h7 one, it
doesn't require to disable backup domain write protection, and rtc_ck
parent clock assignment isn't allowed.
To sum up, stm32mp1 RTC requires 2 clocks, pclk and rtc_ck, and an RTC
alarm interrupt.

dt-bindings: rtc-2123: Make the node name generic

2018-05-14T13:27:50+00:00

According to Devicetree Specification v0.2 document:

"The name of a node should be somewhat generic, reflecting the function
of the device and not its precise programming model."

Do as suggested in the binding example.

dt-bindings: rtc: update stm32-rtc documentation for st, syscfg property

2018-05-06T20:22:42+00:00

RTC driver should not be aware of the PWR registers offset and bits
position. Furthermore, we can imagine that Disable Backup Protection (DBP)
relative register and bit mask could change depending on the SoC. So this
patch moves st,syscfg property from single pwrcfg phandle to pwrcfg
phandle/offset/mask triplet.

rtc: isl12026: new driver.

2018-03-17T13:20:51+00:00

The ISL12026 is a combination RTC and EEPROM device with I2C
interface.  The standard RTC driver interface is provided.  The EEPROM
is accessed via the NVMEM interface.

Pull RTC updates from Alexandre Belloni:
 "There is nothing scary this cycle, mostly driver fixes and updates.

  The core fix has been in for a while and has been tested on multiple
  kernel revisions by multiple teams.

  Core:
   - Fix setting the alarm to the next expiring timer

  New drivers:
   - Mediatek MT7622 RTC
   - NXP PCF85363
   - Spreadtrum SC27xx PMIC RTC

  Drivers updates:
   - Use generic nvmem to expose the Non volatile ram for ds1305,
     ds1511, m48t86 and omap
   - abx80x: solve possible race condition at probe
   - armada38x: support trimming the RTC oscillator
   - at91rm9200: fix reading the alarm value at boot
   - ds1511: allow waking platform
   - m41t80: rework square wave output
   - pcf8523: support trimming the RTC oscillator
   - pcf8563: fix clock output rate
   - pl031: make interrupt optional
   - xgene: fix suspend/resume"

dt-bindings: rtc: imxdi: Improve the bindings text

2017-11-20T21:48:20+00:00

Improve the bindings text by doing the following changes:

- Remove the i.MX53 reference, as the RTC on i.MX53 is a different hardware
- Add 'clocks' to the list of required properties
- Explain that the optional security violation irq is the second entry
- Use the real unit address and irq numbers for i.MX25
