This helps, but it only addresses one part of one of the 4 reasons I listed as motivation for my revert. For example serial8250_do_shutdown() also clearly intends to disable the FIFOs.OK. So, let's fix that :-)I already did, or at least tried to, on Thursday [1].quoted
By all means, it would be really nice to push forward and fix the garbage issue on JZ4780, as well as the transmission issue on AM335x. AM335x is a wildly popular platform, and it's not funny to break it.Well, clearly not if it was broken in v4.10 & only just fixed..? And from Marek's commit message the patch in v4.10 doesn't break the whole system just RS485.quoted
So, let's please stop discussing which board we'll break and just fix both.I completely agree that would be ideal and I wrote a patch hoping to do that on Thursday, but didn't get any response on testing. It's late in the cycle hence a revert made sense. Simple as that.
A revert makes sense now, I'll go queue this up, thanks. greg k-h
