* [PATCH 4/4] rtc: rv3029c2: constify i2c_device_id
From: Arvind Yadav @ 2017-08-19 19:07 UTC (permalink / raw)

In-Reply-To: <1503169678-18078-1-git-send-email-arvind.yadav.cs@gmail.com>
i2c_device_id are not supposed to change at runtime. All functions
working with i2c_device_id provided by <linux/i2c.h> work with
const i2c_device_id. So mark the non-const structs as const.

This driver is in my tree already, no need to resend it again.
Thanks.

+Pincontrol driver for RK805 Power management IC.
+
+RK805 has 2 pins which can be configured as GPIO output only.
+
+Please refer file <devicetree/bindings/pinctrl/pinctrl-bindings.txt>
+for details of the common pinctrl bindings used by client devices,
+including the meaning of the phrase "pin configuration node".
+
+Optional Pinmux properties:
+--------------------------
+Following properties are required if default setting of pins are required
+at boot.
+- pinctrl-names: A pinctrl state named per <pinctrl-binding.txt>.
+- pinctrl[0...n]: Properties to contain the phandle for pinctrl states per
+ <pinctrl-binding.txt>.
+
+The pin configurations are defined as child of the pinctrl states node. Each
+sub-node have following properties:
+
+Required properties:
+------------------
+- #gpio-cells: Should be two. The first cell is the pin number and the
+ second is the GPIO flags.
+
+- gpio-controller: Marks the device node as a GPIO controller.
+
+- pins: List of pins. Valid values of pins properties are: gpio0, gpio1.
+
+First 2 properties must be added in the RK805 PMIC node, documented in
+Documentation/devicetree/bindings/mfd/rk808.txt
+
+Optional properties:
+-------------------
+Following are optional properties defined as pinmux DT binding document
+<pinctrl-bindings.txt>. Absence of properties will leave the configuration
+on default.
+ function,
+ output-low,
+ output-high.
+
+Valid values for function properties are: gpio.
+
+Theres is also not customised properties for any GPIO.
+
+Example:
+--------
+rk805: rk805@18 {
+ compatible = "rockchip,rk805";
+ ...
+ gpio-controller;
+ #gpio-cells = <2>;
+
+ pinctrl-names = "default";
+ pinctrl-0 = <&pmic_int_l>, <&rk805_default>;
+
+ rk805_default: pinmux {
+ gpio01 {
+ pins = "gpio0", "gpio1";
+ function = "gpio";
+ output-high;
+ };

RK805 is one of Rockchip PMICs family, it has 2 output only GPIOs.
This driver is also designed for other Rockchip PMICs to expend.
Different PMIC maybe have different pin features, for example,
RK816 has one pin which can be used for TS or GPIO(input/out).
The mainly difference between PMICs pins are pinmux, direction
and output value, that is 'struct rk805_pin_config'.

We can reuse the clk driver for the RK805 PMIC. So let's add
the RK805 in the Kconfig description.

The RK805 chip is a Power Management IC (PMIC) for multimedia and handheld
devices. It contains the following components:
- Regulators
- RTC
- Clocking
Both RK808 and RK805 chips are using a similar register map,
so we can reuse the RTC and Clocking functionality.

* [rtc-linux] [RESEND v9 03/12] regulator: rk808: Add regulator driver for RK805

In-Reply-To: <1502848628-27757-1-git-send-email-chenjh@rock-chips.com>
From: Elaine Zhang <zhangqing@rock-chips.com>
Add support for the rk805 regulator. The regulator module consists
of 4 DCDCs, 3 LDOs.
The output voltages are configurable and are meant to supply power
to the main processor and other components.

* [PATCH v2 1/1] rtc: rtctest: Improve support detection
From: Lukáš Doktor @ 2017-08-15 8:46 UTC (permalink / raw)
To: ldoktor, a.zummo, linuxppc-dev, sboyd, linux-kernel,
alexandre.belloni, linux-kselftest, john.stultz, tglx, shuah,
linux-rtc
In-Reply-To: <20170815084600.6285-1-ldoktor@redhat.com>
The rtc-generic and opal-rtc are failing to run this test as they do not
support all the features. Let's treat the error returns and skip to the
following test.
Theoretically the test_DATE should be also adjusted, but as it's enabled
on demand I think it makes sense to fail in such case.

* [PATCH v2 0/1] rtc: rtctest: Support opal-rtc and rtc-generic
From: Lukáš Doktor @ 2017-08-15 8:45 UTC (permalink / raw)

alexandre.belloni, linux-kselftest, john.stultz, tglx, shuah,

On ppc64le machines the opal-rtc, resp rtc-generic in guest is used. They only
support minimal set of functionality and fail this test in not-yet treated
way. This extends the checks and skips to the next test when feature is not
supported.
Changes in v2:
- Removed the double EINVAL check
- Added missing space before "EIO" check.
