Instead of using legacy suspend/resume methods, using newer dev_pm_ops structure allows better control over power management. Also, 'wake_en' variable is moved, because it is only used when CONFIG_PM_SLEEP is enabled. Signed-off-by:

The rtc-ds1307 driver does not properly handle block operations bigger than 32 bytes in either of the two modes supported (SMbus native, or emulated if not supported by the SMbus platform driver). It also does not properly handle userland-supplied input (block operation length) through sysfs and may suffer a type of buffer overrun. The driver has been modified with proper input validation, buffer sizes, and now splits block transfers bigger than 32 bytes into separate transfers. Explanation : Buffer size allocated is I2C_SMBUS_BLOCK_MAX which equals to 32 as per the SMbus spec. Reads and write may be up to 56 bytes (to the NVRAM). This patch allocated a 255 byte buffer, the maximum allowable (address is an u8). It's not only a buffer problem, SMbus only supports up to 32 bytes transfer at once, so it's needed to split bigger transfers. Patch successfully tested on 3.2.27; cleanly applies on 3.7-rc4.

Use devm_rtc_device_register() for registering RTC device. This will reduce the code for unregistering RTC device in cleanup path and remove the implementation of remove callback of platform driver. Signed-off-by:

The irq name of tegra rtc shows as "rtc alarm" which actually does not reflect the name related to driver. Passing the device name to have the irq names with driver name. Signed-off-by:

Make the Tegra RTC controller driver define its PM callbacks through a struct dev_pm_ops object rather than by using legacy PM hooks in struct platform_driver. Signed-off-by:

CONFIG_PM doesn't actually enable any of the PM callbacks, it only allows to enable CONFIG_PM_SLEEP and CONFIG_PM_RUNTIME. This means if CONFIG_PM is used to protect system sleep callbacks then it may end up unreferenced if only runtime PM is enabled. Hence protecting sleep callbacks with CONFIG_PM_SLEEP. Signed-off-by:
