Did almost a year ago, but unfortunately got caught by RISC-V bustle, Sorry for github links: Almost "clean" branch: https://github.com/maquefel/linux/tree/ep93xx_dt_rework Dirty, last known good branch: https://github.com/maquefel/linux/tree/gpio/devel-ep93xx-rework-v6 But all my users moved from ts7250 usage to other products, so i am okay if it vanishes from main tree... I have a dozen of ts7250, even with TS-DIO24, TS-SER4, CAN etc..., if someone is interested in Device Tree version of ep93xx/ts7250, it's not a problem for me to finalize the current work on the top of most recent version, but i can test only on ts7250. Yours, Nikita Shubin.
