* of/address: Clean up function declarationsGrant Likely2010-08-011-0/+1
| | | | | | | | | | | | This patch moves the declaration of of_get_address(), of_get_pci_address(), and of_pci_address_to_resource() out of arch code and into the common linux/of_address header file. This patch also fixes some of the asm/prom.h ordering issues. It still includes some header files that it ideally shouldn't be, but at least the ordering is consistent now so that of_* overrides work. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

* | of: Remove duplicate fields from of_platform_driverGrant Likely2010-05-221-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | .name, .match_table and .owner are duplicated in both of_platform_driver and device_driver. This patch is a removes the extra copies from struct of_platform_driver and converts all users to the device_driver members. This patch is a pretty mechanical change. The usage model doesn't change and if any drivers have been missed, or if anything has been fixed up incorrectly, then it will fail with a compile time error, and the fixup will be trivial. This patch looks big and scary because it touches so many files, but it should be pretty safe.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We use a rather complicated logic to support eTSEC and eTSEC2.0 registers maps in a single driver. Currently, the code tries to unmap 'regs', but for non-eTSEC2.0 controllers 'regs' doesn't point to a mapping start, and this might cause badness on probe failure or module removal: Freescale PowerQUICC MII Bus: probed Trying to vfree() nonexistent vm area (e107f000) ------------[ cut here ]------------ Badness at c00a7754 [verbose debug info unavailable] NIP: c00a7754 LR: c00a7754 CTR: c02231ec [...] NIP [c00a7754] __vunmap+0xec/0xf4 LR [c00a7754] __vunmap+0xec/0xf4 Call Trace: [df827e50] [c00a7754] __vunmap+0xec/0xf4 (unreliable) [df827e70] [c001519c] iounmap+0x44/0x54 [df827e80] [c028b924] fsl_pq_mdio_probe+0x1cc/0x2fc [df827eb0] [c02fb9b4] of_platform_device_probe+0x5c/0x84 [df827ed0] [c0229928] really_probe+0x78/0x1a8 [df827ef0] [c0229b20] __driver_attach+0xa4/0xa8 Fix this by introducing a proper priv structure (finally!), which now holds 'regs' and 'map' fields separately.

So, instead of introducing the casts, rework the code to substitute an offset from an already mapped area. This makes the code a lot simpler and less duplicated. Plus, from now on we don't actually map reserved registers on non-etsec2.0 devices, so we have more chances to catch programming errors.

* fsl_pq_mido: Set the first UCC as the mii management interface masterHaiying Wang2009-06-031-1/+5
| | | | | | | | | | | | | | Current code makes the UCC whose register range includes the current mdio register to be the MII managemnt interface master of the QE. If there is more than one mdio bus for QE, the UCC of the last mdio bus will be the MII management interface master which will make the primary mdio bus working unproperly, e.g. can not get the right clock. Normally the primary mdio bus is the first UEC's mdio bus. This patch allows the first UCC to be the MII management interface master of the multiple UCC mdio buses.

* net: fix fsl_pq_mdio driver to use module_init()Grant Likely2009-04-271-1/+1
| | | | | | | | | | | | | | | | | Modules are not supposed to use any of the *_initcall*() hooks as the entry point. fsl_pq_mdio.c was using subsys_initcall_sync() instead of module_init() to guarantee that the MDIO bus was initialized before the Ethernet driver goes looking for the phy. However, the recent OF helpers rework happens to also make sure PHY connection is deferred to .open time, so using an initcall is no longer necessary. This patch replaces the initcall with a more traditional an accepted module_init() call. Tested on Freescale MPC8349emitxgp eval board.
