This is a reasonable amount of support for the ep93xx in mainline now.
Drivers have been added recently for keypad, pwm, framebuffer, dma, etc.
There are patches currently on the ARM kernel list for an spi driver
which look like the are suitable for merging soon.

I believe there was some fallout between Cirrus and Lennert a while
back. Cirrus logic were basically useless as far as support went, we
contacted them several times with issues and never got anywhere with
them. You are correct that the ep93xx line is now end of life, Cirrus
Logic decided to abandon the ARM market. We are still keen to get better
support in the mainline since there are a number of ep93xx based boards
around.
