Dear Maintainers, if Allwinner i2c locks, the is a LCR register (reg_base + 0x20), which shows directly the state of the SCL and SDA lines. So you can see which line (if any) is pulled externally low. Is there a similar usefull register in the original MV64XXX MARVELL chip? I'd like to make the patch https://bitbucket.org/hlauer/kernel/src/master/patches/i2c-buslock.patchl working for that chip, too. Thanks for any ideas.
