* rtc-v3020: add ability to access v3020 chip with GPIOsMike Rapoport2009-04-021-0/+6
| | | | | | | | | | | | The v3020 RTC can be connected to GPIOs as well as to memory-like interface. Add ability to use GPIO bit-bang for v3020 read-write access.

* [PATCH] Add v3020 RTC supportRaphael Assenat2006-06-251-0/+35
This patch adds support for the v3020 RTC from EM Microelectronic. The v3020 RTC is designed to be connected on a bus using only one data bit. Since any data bit may be used, it is necessary to specify this to the driver by passing a struct v3020_platform_data pointer (see include/linux/rtc-v3020.h) to the driver. Part of the following code comes from the kernel patchs produced by Compulab for their products. The original file (available here: http://raph.people.8d.com/misc/emv3020.c) was released under the terms of the GPL license.
