rtc: add NXP PCF8523 support 2012-12-18T01:15:21+00:00 Thierry Reding thierry.reding@avionic-design.de 2012-12-18T00:02:44+00:00 f803f0d079ded4272d7a1c9813bfd24c58b8ee5f Add an RTC driver for PCF8523 chips by NXP Semiconductors. No support is currently provided for the alarm and interrupt functions. Only the time and date functionality is implemented.
