Subject: [PATCH 0/2] i2c: i2c-ocores: Add support for sparc, custom set and get functions, and the GRLIB port of the controller
Date: Tue, 23 Oct 2012 17:03:55 +0200 [thread overview]
Message-ID: <1351004637-11049-1-git-send-email-andreas@gaisler.com> (raw)
On sparc, irqs are not present as an IORESOURCE in the struct platform_device
representation. Therefore, for sparc the irq needs to be fetched in a different
manner.
The GRLIB port of the ocores i2c controller needs custom getreg and setreg
functions to allow for big endian register access and to deal with the fact that
the PRELOW and PREHIGH registers have been merged into one register.
