Subject: Obtaining official minor device number : How ? (tried device@lanana.org, no answer)
Date: Mon, 22 Aug 2005 23:10:45 +0200 [thread overview]
Message-ID: <430A3F55.7090909@246tNt.com> (raw)
Hello,
I'd like to obtain some minor device number and I'm not sure how to do
so. I've seen that a request must be sent to device@lanana.org, and I've
done it, following the instructions (I think). I've sent it twice, a
first time two month ago, then again a little less than a month ago.
Each time with no anwer ;(
Here is the mail I sent each time (greeting & thanks snipped) :
----<CUT>----
I'd like to obtain an official range in the low-density serial port
(major=204) for the serial ports on the SoC MPC5200. This chip has 6 PSC
that can act as serial port. I'd suggest naming them ttyPSC[0-5] and
just using "PPC PSC - port n" as decription since freescale might decide
to reuse the PSC for future chips in the same family.
Something like that I'd guess
148 = /dev/ttyPSC0 PPC PSC - port 0
...
153 = /dev/ttyPSC5 PPC PSC - port 5
Currently the driver (drivers/serial/mpc52xx_uart.c) uses the "standard"
/dev/ttySx but that causes conflicts when for example a pcmcia serial
card is present since both driver want the same serial. Apparently the
"low density serial port" major is there for theses kind of ports so ;)
----<CUT>----
Is there some critical information missing ? Something I don't get ?
Sylvain
