I2C MV64XXX: Showing Allwinner debug LCR register in bus lock case

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.

Greetings
  Hermann
