* rtc: omap: prevent disabling of clock/module during suspendTero Kristo2016-11-041-6/+26
| | | | | | | | | | | | | | | | | If RTC is running from an internal clock source, the RTC module can't be disabled; otherwise it stops ticking completely. Current suspend handler implementation disables the clock/module unconditionally, instead fix this by disabling the clock only if we are running on external clock source, which is not affected by suspend. The prevention of disabling the clock must be done via implementing the runtime_pm handlers for the device, and returning an error code from the runtime suspend handler; otherwise OMAP core PM will disable the clocks for the driver.

* rtc: omap: Fix selecting external oscLokesh Vutla2016-11-041-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RTC can be clocked from an external 32KHz oscillator, or from the Peripheral PLL. The RTC has an internal oscillator buffer to support direct operation with a crystal. ---------------------------------------- | Device --------- | | | | | | | RTCSS | | | --------- | | | OSC |<------| RTC | | | | |------>| OSC |--- | | | | -------- | | | | | ----|clk | | | -------- | | | | | | PRCM |--- | | | | -------- -------- | ---------------------------------------- The RTC functional clock is sourced by default from the clock derived from the Peripheral PLL. In order to select source as external osc clk the following changes needs to be done: - Enable the RTC OSC (RTC_OSC_REG[4]OSC32K_GZ = 0) - Enable the clock mux(RTC_OSC_REG[6]K32CLK_EN = 1) - Select the external clock source (RTC_OSC_REG[3]32KCLK_SEL = 1) Fixes: 399cf0f63f6f2 ("rtc: omap: Add external clock enabling support") Signed-off-by: Keerthy <j-keerthy@ti.com> Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com> Signed-off-by: Dave Gerlach <d-gerlach@ti.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>
* rtc: cmos: Don't enable interrupts in the middle of the interrupt handlerVille Syrjälä2016-10-201-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Using spin_lock_irq()/spin_unlock_irq() from within the interrupt handler is a no-no. Let's save/restore the flags to avoid turning on interrupts prematurely. We hit this in a bunch of our CI systems, but for whatever reason I wasn't able to reproduce on my own machine, so this fix is just based on the backtrace.

This patch restores the RTC alarm on resume to ensure that kernel and hardware are in sync. The case we've seen is Intel Rapid Start, which is a firmware-mediated feature that automatically transitions systems from suspend-to-RAM to suspend-to-disk without OS involvement. It does this by setting the RTC alarm and a flag that indicates that on wake it should perform the transition rather than re-starting the OS. However, if the OS has set a wakeup alarm that would wake the machine earlier, it refuses to overwrite it and allows the system to wake instead. This fails in the following situation: 1) User configures Intel Rapid Start to transition after (say) 15 minutes 2) User suspends to RAM. Firmware sets the wakeup alarm for 15 minutes in the future 3) User resumes after 5 minutes. Firmware does not reset the alarm, and as such it is still set for 10 minutes in the future 4) User suspends after 5 minutes. Firmware notices that the alarm is set for 5 minutes in the future, which is less than the 15 minute transition threshold. It therefore assumes that the user wants the machine to wake in 5 minutes 5) System resumes after 5 minutes The worst case scenario here is that the user may have put the system in a bag between (4) and (5), resulting in it running in a confined space and potentially overheating. This seems reasonably important. The Rapid Start support code got added in 3.11, but it can be configured in the firmware regardless of kernel support.

| * rtc: cmos: Clear ACPI-driven alarms upon resumeGabriele Mazzotta2016-09-211-0/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently ACPI-driven alarms are not cleared when they wake the system. As consequence, expired alarms must be manually cleared to program a new alarm. Fix this by correctly handling ACPI-driven alarms. More specifically, the ACPI specification [1] provides for two alternative implementations of the RTC. Depending on the implementation, the driver either clear the alarm from the resume callback or from ACPI interrupt handler: - The platform has the RTC wakeup status fixed in hardware (ACPI_FADT_FIXED_RTC is 0). In this case the driver can determine if the RTC was the reason of the wakeup from the resume callback by reading the RTC status register. - The platform has no fixed hardware feature event bits. In this case a GPE is used to wake the system and the driver clears the alarm from its handler.

So, neither hpet_default_delta nor hpet_t1_cmp is initialized by the time interrupt is raised in the given situation, and this results in NMI watchdog LOCKUP. It has only been observed sporadically on kdump secondary kernels.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | V1F indicates that the time accuracy may have been compromised because of a voltage drop (possibly only temporary) below VLOW1, which stops the temperature compensation. When the time is set, the accuracy is restored, so V1F should be cleared in order to indicate this and to be able to detect the next temperature compensation loss. This is the same principle as for V2F, which is cleared when the time is set to indicate that the time is no longer invalid and to be able to detect the next data loss.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the application manual of the RX8900, the RESET bit must be set to 1 to prevent a timer update while setting the time. This also resets the subsecond counter. The application manual of the RV-8803 does not mention such a requirement, and it says that the 100th Seconds register is cleared when writing to the Seconds register, but using the RESET bit for the RV-8803 too should not be an issue and is probably safer. This change also ensures that the RESET bit is initialized properly in all cases. Indeed, all the registers must be initialized if the voltage has been lower than VLOW2 (triggering V2F), but not low enough to trigger a POR.

Consequently, the workaround must be applied for all the I²C transfers. This commit abstracts the I²C transfer code into register access functions. This avoids duplicating the I²C workaround everywhere. This also avoids the duplication of the code handling the return value of i2c_smbus_read_i2c_block_data(). Error messages are issued in case of definitive register access failures (if the workaround fails). This change also makes the I²C transfer return value checks consistent.

| * rtc: pcf85063: fix year rangeAlexandre Belloni2016-07-191-7/+5
| | | | | | | | | | | | | | | | | | | | The year range is not validated properly As the driver has been mainlined in 2014, it is not an issue to stop handling dates between 1970 and 2000 with the benefit of handling dates up to 2100.

| * rtc: explicitly set tm_sec = 0 for drivers with minute accurancyUwe Kleine-König2016-07-195-0/+6
| | | | | | | | | | | | | | | | | | Since all time members of the alarm data is initialized to -1 the drivers are responsible to set the tm_sec member to 0.

| * rtc: s3c: Add s3c_rtc_{enable/disable}_clk in s3c_rtc_setfreq()Alim Akhtar2016-07-191-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: s3c: Remove unnecessary call to disable already disabled clockAlim Akhtar2016-07-191-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | At the end of s3c_rtc_probe(), s3c_rtc_disable_clk() being called with rtc clock already disabled (by s3c_rtc_gettime()), which looks extra and unnecessary call. Lets clean it up.

| | | | | | | | | | | | | | | | | | | | If devm_add_action() fails we are explicitly calling the cleanup to free the resources allocated. Lets use the helper devm_add_action_or_reset() and return directly in case of error, as we know that the cleanup function has been already called by the helper if there was any error.
