Subject: [PATCH RFC 0/3] i2c-nomadik changes
Date: Wed, 30 May 2012 19:45:30 +0200 [thread overview]
Message-ID: <cover.1338398567.git.rubini@gnudd.com> (raw)
The patch set turns a platform device into an amba device. Its users,
i.e. mach-ux500, are converted too. The set has no external
dependencies, although is has no visible effect until other patches
are accepted.
Reasoning:
In the STA2X11 I/O hub we are exporting a number of AMBA peripherals
to the PCI world. Using a generic pci-amba driver there is no further
code for each device, provided they are already registered under the
AMBA bus. I already submitted the generic bridge
(https://lkml.org/lkml/2012/5/28/194).
Status of this patch set:
The users of the driver (i.e. mach-ux600) compile properly, but I
couldn't test on any board. The driver, as is, works on x86 under the
PCI bridge, with the not-yet-upstream clock framework and platform
data for sta2x11 devices. However, this set is not introducing any
dead code as it only adds more flexibility. The big part of it is a
massive s/platform_device/amba_device/ and s/pdev/adev/ .
The cell-id I used in the table are the one for ux500 (only as far as
I know from the stn-8815 manuals) and the one for STA2X11.
