[PATCH v6 0/4] ARM: dts: sun9i: Enable X-Powers AC100 RTC

[Chen-Yu Tsai]

Hi everyone,

This was "mfd: ac100: Add support for X-Powers AC100 audio codec / RTC
combo IC". The driver bits have all been merged.

Changes since v5:

  - Driver bits merged and dropped from series.
  - Added fix to rtc-ac100 clock register code to honor the
    "clock-output-names" DT property.
  - Added "clk-div" and "clk-mult" to osc32k placeholder clock node

Changes since v4:

  - Style changes to DT bindings.
  - Added commit message to DT bindings commit.

Changes since v3:

  - bulk write support for regmaps without raw formatting patch merged
    and thus dropped from series.

  - sun9i device node re-ordering patches merged and thus dropped from
    series.

  - Fixed device node name and added labels to device tree binding example.

  - Moved 4M_adda clock to codec side, and added clock bindings to codec
    node.

  - Rename RTC clock output related prefixes from clk32k to clkout.

  - Rename default clock output names to cko{1,2,3}-rtc.

  - Move struct tm to/from RTC conversion offsets inline with reg[]
    assignments

  - Drop separate mutex and use rtc->ops_lock in interrupt handler.

  - Use platform_get_irq instead of of_get_irq.

  - Add struct of_device_id and .of_match_table to RTC driver.

Changes since v2:

  - Fix ac100_codec interrupt line in DT binding example.

  - Fix copy-paste errors in RTC set_alarm. Alarm now works.

  - Drop file name from MFD driver.

  - Add / update copyright notices.

  - Change license of RTC driver to GPL v2, matching MFD driver.

  - Fix MFD driver MODULE_LICENSE to match license declaration in header.

Changes since v1:

  - Complete register definitions and regmap regions.


Patch 1 adds a fix to rtc-ac100 clock register code to honor the
"clock-output-names" DT property.

Patch 2 adds the AC100 device nodes to the A80 Optimus board dts.

Patch 3 adds the AC100 device nodes to the Cubieboard4 board dts.

Patch 4 changes the fixed osc_32k clk to a fixed factor clk,
representing the 32k clk input pin on the SoC, and also hooks up the
ac100 rtc clk output to this clk in the board dts files.
