2016-03-14rtc: make class.c explicitly non-modularPaul Gortmaker1-13/+0
The Makefile/Kconfig currently controlling compilation of this code is: obj-$(CONFIG_RTC_CLASS) += rtc-core.o rtc-core-y := class.o interface.o drivers/rtc/Kconfig:menuconfig RTC_CLASS drivers/rtc/Kconfig: bool "Real Time Clock" ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the code there is no doubt it is builtin-only. We don't replace module.h with init.h since the file does need to know what a struct module is. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments.

2016-03-14rtc: pcf85063: fix time/date settingJuergen Borleis1-23/+55
When setting a new time/date the RTC's clock must be stopped first, in order to write the time/date registers in an atomic manner. So, this change stops the clock first and then writes the time/date registers and the clock control register (to re-enable the clock) in one turn.

2016-03-14rtc: pcf85063: simplify code to read the current timeJuergen Borleis1-26/+21
By using i2c_smbus_read_i2c_block_data() the code is now much simpler. While at it: when reading the RTC's seconds register, all time/date registers are frozen until the RTC's year register is read. So it is important to read all time/date registers in one turn to not lose a second event. Make it more clear why the read must happen in this way.

2016-03-14rtc: Add functions to set and read rtc offsetJoshua Clayton2-0/+58
A number of rtc devices, such as the NXP pcf2123 include a facility to adjust the clock in order to compensate for temperature or a crystal, capacitor, etc, that results in the rtc clock not running at exactly 32.768 kHz. Data sheets I have seen refer to this as a clock offset, and measure it in parts per million, however they often reference ppm to 2 digits of precision, which makes integer ppm less than ideal. We use parts per billion, which more than covers the precision needed and works nicely within 32 bits Signed-off-by: Joshua Clayton <[email protected]> Signed-off-by: Alexandre Belloni <[email protected]>

To make RTC block of MAX77686/MAX77802 as independent driver, move the registration of i2c device, regmap for register access and irq_chip for interrupt support inside the RTC driver. Removed the same initialisation from MFD driver. Having this change will allow to reuse this driver for different PMIC/devices from Maxim Semiconductor if they kept same RTC IP on different PMIC. Some of examples as PMIC MAX77620, MAX20024 where same RTC IP used and hence driver for these chips will use this driver only for RTC support.

2016-03-14rtc: pcf2123: avoid resetting the clock if possibleJoshua Clayton1-3/+12
pcf2123 data sheet recommends a software reset when the chip is first powered on. This change avoids resetting the chip every time the driver is loaded, which has some negative effects. There are several registers including a clock rate adjustment that really should survive a reload of the driver (or reboot). In addition, stopping and restarting the clock to verify the chip is there is not a good thing once the time is set. According to the data sheet, the seconds register has a 1 in the high bit when the voltage has gotten low. We check for this condition, as well as whether the time retrieved from the chip is valid. We reset the rtc only if the time is not reliable and valid. This is sufficient for checking for the presence of the chip, as either all zeros or all 0xff will result in an invalid time/date Signed-off-by: Joshua Clayton <[email protected]> Signed-off-by: Alexandre Belloni <[email protected]>

Switch to resource-managed function devm_led_classdev_register instead of led_classdev_register and remove unneeded led_classdev_unregister. Also, remove unnecessary function pdev_to_gpio, platform_set_drvdata in the probe function and the remove function, s3c24xx_led_remove as it is now has nothing to do. The Coccinelle semantic patch used to make this change is as follows: //<smpl> @platform@ identifier p, probefn, removefn; @@ struct platform_driver p = { .probe = probefn, .remove = removefn, }; @prb@ identifier platform.probefn, pdev; expression e; @@ probefn(struct platform_device *pdev, ...) { ... e = - led_classdev_register + devm_led_classdev_register (...); ... ?- led_classdev_unregister(...); ... } @remove depends on prb@ identifier platform.removefn; @@ removefn(...) { ... ?- led_classdev_unregister(...); ... } //</smpl> Signed-off-by: Amitoj Kaur Chawla <[email protected]> Signed-off-by: Jacek Anaszewski <[email protected]>
