Note if you decide to take this as is, please s/bananapi.org/lemaker.org/ in the commit message, bananapi.org is an unofficial site, I should have put lemaker.org there. Note btw that we already have this problem for spi1, the current spi1_pins_a does not include the cs1 pin, because it was added for use in sun7i-a20-olinuxino-micro.dts where only cs0 is hooked up, but I decided to leave that as is for now. Also the "primary" binding for spi2 is to PORTB, but our spi2_pins_a binds it to PORTC, so it should be renamed spi2_pins_b IMHO.
