Commit 63d222b9 authored by Linus Torvalds's avatar Linus Torvalds

Merge tag 'rtc-4.7' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux

Pull RTC updates from Alexandre Belloni:
 "Subsystem wide cleanups:
   - Use IS_ENABLED() instead of checking for built-in or module
   - remove useless DRV_VERSION
   - remove CLK_IS_ROOT
   - remove UIE signaling

  Drivers:
   - ds1302: rewritten to be a proper SPI device driver
   - m41t80: huge cleanup, alarm, wakelarm ans oscialltor failure
     detection support
   - rv3029: switch to regmap to handle rv3049, alarm support, fixes
   - zynqmp: enable switching to battery power, fixes
   - small fixes for at91sam9, da9053, ds1307, ds1685, ds3232, r2025,
     sa1100, snvs, stmp3xxx, tps6586x"

* Maxim/Dallas Semiconductor DS-1302 RTC
Simple device which could be used to store date/time between reboots.
The device uses the standard MicroWire half-duplex transfer timing.
Master output is set on low clock and sensed by the RTC on the rising
edge. Master input is set by the RTC on the trailing edge and is sensed
by the master on low clock.
Required properties:
- compatible : Should be "maxim,ds1302"
Required SPI properties:
- reg : Should be address of the device chip select within
the controller.
- spi-max-frequency : DS-1302 has 500 kHz if powered at 2.2V,
and 2MHz if powered at 5V.
- spi-3wire : The device has a shared signal IN/OUT line.
- spi-lsb-first : DS-1302 requires least significant bit first
transfers.
- spi-cs-high: DS-1302 has active high chip select line. This is
required unless inverted in hardware.
Example:
spi@901c {
#address-cells = <1>;
#size-cells = <0>;
compatible = "icpdas,lp8841-spi-rtc";
reg = <0x901c 0x1>;
rtc@0 {
compatible = "maxim,ds1302";
reg = <0>;
spi-max-frequency = <500000>;
spi-3wire;
spi-lsb-first;
spi-cs-high;
};
};
