X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ac771ed746c800749ec5adbb4b7c22ce1d89943e;p=linux.git

rtc: rv8803: add Epson RX8803 support

The Epson rx8803 is mostly similar to the Microcrystal RV8803 but the size
of the offset register is 4 bits vs 6 bits but it has a configurable
temperature compensation.
