rtc: ds1307: Fix relying on reset value for weekday

2016-09-30T08:12:45+00:00

commit e29385fab0bf94017fac130ee32f5bb2daf74417 upstream. The reset value of weekday is 0x1. This is wrong since the reset values of the day/month/year make up to Jan 1 2001. When computed weekday comes out to be Monday. On a scale of 1-7(Sunday - Saturday) it should be 0x2. So we should not be relying on the reset value. Hence compute the wday using the current date/month/year values. Check if reset wday is any different from the computed wday, If different then set the wday which we computed using date/month/year values.

rtc: s3c: Add s3c_rtc_{enable/disable}_clk in s3c_rtc_setfreq()

2016-08-20T16:11:04+00:00

commit 70c96dfac0e231424e17743bd52f6cd2ff1f2439 upstream. As per code flow s3c_rtc_setfreq() will get called with rtc clock disabled and in set_freq we perform h/w registers read/write, which results in a kernel crash on exynos7 platform while probing rtc driver. Below is code flow: s3c_rtc_probe() clk_prepare_enable(info->rtc_clk) // rtc clock enabled s3c_rtc_gettime() // will enable clk if not done, and disable it upon exit s3c_rtc_setfreq() //then this will be called with clk disabled This patch take cares of such issue by adding s3c_rtc_{enable/disable}_clk in s3c_rtc_setfreq().

rtc: tps6586x: rename so module can be autoloaded

2016-05-21T15:07:17+00:00

This module is loaded by the related mfd driver which has the needed MODULE_DEVICE_TABLE(i2c,...). This patch fix the modalias when the rtc driver is built as a module, so the right name is used. Everything operates correctly when this module is builtin. Fixes: esdc59ed3865 ("rtc: add RTC driver for TPS6586x") Signed-off-by: Nicolas Chauvet Signed-off-by: Alexandre Belloni

rtc: rv3029: hide unused i2c device table

2016-05-21T15:07:16+00:00

The added support for SPI mode made it possible to configure the driver when I2C is disabled, leaving an unused device table: drivers/rtc/rtc-rv3029c2.c:794:29: error: 'rv3029_id' defined but not used [-Werror=unused-variable] This moves the table inside of the #ifdef section that has the only user, to avoid the harmless warning.

rtc: rs5c372: r2025: fix check for 'oscillator halted' condition

2016-05-21T15:07:16+00:00

The R2025SD chip, according to its data sheet, sets the /XST bit to zero if the oscillator stops. Hence the check for this condition was wrong. Signed-off-by: Thomas Koeller Signed-off-by: Alexandre Belloni

rtc: rv3029: fix set_time function
