Re: [PATCH] serial: 8250: probe all 16550A variants by default

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

 



This change breaks all my devices: OMAP-L138 (davinci based), LS1021A, T1040, Marvell (kirkwood2 based). Only enabling VARIANTS on all my devices fix the issue.

On NXP T1040, the UART is typically detected as 16550A_FSL64. After said

completely garbled and missing characters.
Interesting that there's*new*  powerpc hardware that needs these
variants. I based the patch on the fact that, on x86 at least, hardware
using these variants hasn't been made for a long time.
