2019-04-04rtc: snvs: use devm_platform_ioremap_resource() to simplify codeAnson Huang1-3/+1
Use the new helper devm_platform_ioremap_resource() which wraps the platform_get_resource() and devm_ioremap_resource() together, to simplify the code. Signed-off-by: Anson Huang <Anson.Huang@nxp.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>

2019-04-04rtc: snvs: use dev_pm_set_wake_irq() to simplify codeAnson Huang1-21/+4
With calling dev_pm_set_wake_irq() to set SNVS RTC as wakeup source for suspend, generic wake irq mechanism will automatically enable it as wakeup source when suspend, then the suspend/resume callback which are ONLY for enabling/disabling irq wake can be removed, it simplifies the code.

2019-04-04rtc: mt6397: Don't call irq_dispose_mapping.Pi-Hsun Shih1-6/+3
The IRQ mapping was changed to not being created in the rtc-mt6397 driver, so the irq_dispose_mapping is no longer needed. Also the dev_id passed to free_irq should be the same as the last argument passed to request_threaded_irq. This prevents a "Trying to free already-free IRQ 274" warning when unbinding the driver.
