rtc: m48t86: use generic nvmem

2017-10-12T22:10:10Z

Instead of adding a binary sysfs attribute from the driver (which suffers from a race condition as the attribute appears after the device), use the core to register an nvmem device. Signed-off-by: Alexandre Belloni

rtc: m48t86: switch to rtc_register_device

2017-10-12T22:10:08Z

This allows for future improvement of the driver. Signed-off-by: Alexandre Belloni

rtc: m48t86: remove unused platform_data

2017-02-21T20:23:13Z

All users of this driver have been updated to allow the driver to manage it's own resources and do the read/write operations internally. The m48t86_ops are no longer used. Remove the platform_data header and the support code in the driver. Signed-off-by: H Hartley Sweeten Signed-off-by: Alexandre Belloni

rtc: m48t86: verify that the RTC is actually present

2017-02-21T17:16:31Z

The RTC is an optional feature at purchase time on some Technologic Systems boards. Verify that it actually exists by checking if the last two bytes of the NVRAM can be changed. Signed-off-by: H Hartley Sweeten Signed-off-by: Alexandre Belloni

rtc: m48t86: add NVRAM support

2017-02-12T00:08:01Z

This RTC has 114 bytes of NVRAM. Provide access to it via a binary sysfs 'nvram' attribute file. Signed-off-by: H Hartley Sweeten Signed-off-by: Alexandre Belloni

rtc: m48t86: allow driver to manage its resources

2017-02-12T00:07:38Z

Allow this driver to, optionally, manage it's own resources and do the read/write operations if the platform does not provide them. Signed-off-by: H Hartley Sweeten Signed-off-by: Alexandre Belloni

rtc: m48t86: shorten register name defines

2017-02-12T00:06:35Z

For aesthetics. Shorten all the register names by removing '_REG' from all of them. This helps fix all the checkpatch.pl issues. Signed-off-by: H Hartley Sweeten Signed-off-by: Alexandre Belloni

rtc: m48t86: move m48t86.h to platform_data

2016-06-27T16:15:25Z

m48t86.h belongs to include/linux/platform_data/ Acked-by: Jason Cooper Acked-by: H Hartley Sweeten Acked-by: Alexander Clouter Signed-off-by: Alexandre Belloni

rtc: remove useless DRV_VERSION

2016-05-20T10:33:51Z

Many drivers are defining a DRV_VERSION. This is often only used for MODULE_VERSION and sometimes to print an info message at probe time. This is kind of pointless as they are all versionned with the kernel anyway. Also the core will print a message when a new rtc is found. Signed-off-by: Alexandre Belloni

rtc: drop owner assignment from platform_drivers

2014-10-20T14:21:31Z

A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang
