2019-10-19rtc: ds1343: remove unnecessary mutexAlexandre Belloni
Use rtc_lock and rtc_unlock to lock the rtc from the interrupt handler. This removes the need for a driver specific lock. Link: https://lore.kernel.org/r/20191019204941.6203-7-alexandre.belloni@bootlin.com Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>

2019-10-16rtc: ds1685: add indirect access method and remove plat_read/plat_writeThomas Bogendoerfer
SGI Octane (IP30) doesn't have RTC register directly mapped into CPU address space, but accesses RTC registers with an address and data register. This is now supported by additional access functions, which are selected by a new field in platform data. Removed plat_read/plat_write since there is no user and their usage could introduce lifetime issue, when functions are placed in different modules.

If the RTC HW returns an invalid time, the rtc_year_days() call would crash. This patch adds error logging in this situation, and removes the tm_yday and tm_wday calculations. These fields should not be relied upon by userspace according to man rtc, and thus we don't need to calculate them.

2019-10-07rtc: ds1347: properly handle oscillator failuresAlexandre Belloni
The comment in the probe function stating that it disables oscillator stop detection and glitch filtering is incorrect as it sets bits 3 and 4 while it should be setting 5 and 6 to achieve that. Then, it is safe to assume that the oscillator failure detection is actually enabled. Properly handle oscillator failures by returning -EINVAL when the time and date are know to be incorrect and reset the flag when the time is set.

2019-10-03rtc: interface: use timeu64_t for range_maxEmmanuel Nicolet
For rtc drivers where rtc->range_max is set U64_MAX, like the PS3 rtc, rtc_valid_range() always returns -ERANGE. This is because the local variable range_max has type time64_t, so the test if (time < range_min || time > range_max) return -ERANGE; becomes (time < range_min || time > -1), which always evaluates to true. timeu64_t should be used, since it's the type of rtc->range_max.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "We have a small collection of core framework updates this time, mostly around clk registration by clk providers and debugfs "nice to haves" for rate constraints. I'll highlight that we're now setting the clk_init_data pointer inside struct clk_hw to NULL during clk_register(), which may break some drivers that thought they could use that pointer during normal operations. That change has been sitting in next for a while now but maybe something is still broken. We'l see. Other than that the core framework changes aren't invasive and they're fixing bugs, simplifying, and making things better. On the clk driver side we got the usual addition of new SoC support, new features for existing drivers, and bug fixes scattered throughout. The biggest diffstat is the Amlogic driver that gained CPU clk support in addition to migrating to the new way of specifying clk parents. After that the Qualcomm, i.MX, Mediatek, and Rockchip clk drivers got support for various new SoCs and clock controllers from those vendors.

And the bootloader will validate this flag to check if the booting mode is alarm booting mode, thus we should not clear this flag in kernel, instead bootloader will clear this flag after checking the booting mode.

2019-09-02mfd / platform: cros_ec: Reorganize platform and mfd includesEnric Balletbo i Serra
There is a bit of mess between cros-ec mfd includes and platform includes. For example, we have a linux/mfd/cros_ec.h include that exports the interface implemented in platform/chrome/cros_ec_proto.c. Or we have a linux/mfd/cros_ec_commands.h file that is non related to the multifunction device (in the sense that is not exporting any function of the mfd device). This causes crossed includes between mfd and platform/chrome subsystems and makes the code difficult to read, apart from creating 'curious' situations where a platform/chrome driver includes a linux/mfd/cros_ec.h file just to get the exported functions that are implemented in another platform/chrome driver. In order to have a better separation on what the cros-ec multifunction driver does and what the cros-ec core provides move and rework the affected includes doing: - Move cros_ec_commands.h to include/linux/platform_data/cros_ec_commands.h - Get rid of the parts that are implemented in the platform/chrome/cros_ec_proto.c driver from include/linux/mfd/cros_ec.h to a new file include/linux/platform_data/cros_ec_proto.h - Update all the drivers with the new includes, so - Drivers that only need to know about the protocol include - linux/platform_data/cros_ec_proto.h - linux/platform_data/cros_ec_commands.h - Drivers that need to know about the cros-ec mfd device also include - linux/mfd/cros_ec.h Signed-off-by: Enric Balletbo i Serra <enric.balletbo@collabora.com> Acked-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Acked-by: Mark Brown <broonie@kernel.org> Acked-by: Wolfram Sang <wsa@the-dreams.de> Acked-by: Neil Armstrong <narmstrong@baylibre.com> Acked-by: Alexandre Belloni <alexandre.belloni@bootlin.com> Acked-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Acked-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> Acked-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Acked-by: Sebastian Reichel <sebastian.reichel@collabora.com> Acked-by: Chanwoo Choi <cw00.choi@samsung.com> Reviewed-by: Gwendal Grignou <gwendal@chromium.org> Tested-by: Gwendal Grignou <gwendal@chromium.org> Series changes: 3 - Fix dereferencing pointer to incomplete type 'struct cros_ec_dev' (lkp) Signed-off-by: Lee Jones <lee.jones@linaro.org>

2019-09-01rtc: sun6i: Allow using as wakeup source from suspendAlejandro González
This patch allows userspace to set up wakeup alarms on any RTC handled by the sun6i driver, and adds the necessary PM operations to allow resuming from suspend when the configured wakeup alarm fires a IRQ. Of course, that the device actually resumes depends on the suspend state and how a particular hardware reacts to it, but that is out of scope for this patch. I've tested these changes on a Pine H64 model B, which contains a Allwinner H6 SoC, with the help of CONFIG_PM_TEST_SUSPEND kernel option. These are the interesting outputs from the kernel and commands which show that it works. As every RTC handled by this driver is largely the same, I think that it shouldn't introduce any regression on other SoCs, but I may be wrong.
