* sh: sh7786 clkdev lookups.Paul Mundt2010-03-292-12/+68
| | | | | | | | | | This plugs in clkdev lookups for the SH7786 clocks and migrates off of clock string usage for the TMU clocks. Previously the TMU clocks were aliased to the peripheral clock, so this gets the driver actually toggling the proper clocks now as well. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* clocksource: Deprecate clock string across the SH drivers.Paul Mundt2010-03-293-12/+24
| | | | | | | | | | | | | | We want to get rid of the clock string from platform data entirely, depending on the clkdev-based clock lookup to do the right thing for us instead. This converts all of the SH drivers to request their associated function clocks directly, and if there is no match for that then we fall back on the legacy lookup while warning about it. After all of the outstanding CPUs have been converted to clkdev lookups the clock string will be killed off completely. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* | serial: sh-sci: clkdev updates for MSTP gating.Paul Mundt2010-03-1014-80/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes up some of the I/D/F clock ambiguity in the sh-sci driver. The interface clock in most cases just wraps back to the peripheral clock, while the function clock wraps in to the MSTP bits. As the logic was somewhat inverted, this cleans that up, and also enables all CPUs with SCI MSTP bits to match function clocks through clkdev lookup. As a result, this gets rid of the clk string abuse on the sh side, and the clock string will be killed off once the ARM code has had a chance to sync up. This also enables MSTP gating on CPUs like 7786 which had never wired it up before. Impacted CPUs are primarily all SH-Mobiles, SH7785, and SH7786. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| * driver core: Early dev_name() support.Paul Mundt2010-03-102-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Presently early platform devices suffer from the fact they are unable to use dev_xxx() calls early on due to dev_name() and others being unavailable at the time ->probe() is called. This implements early init_name construction from the matched name/id pair following the semantics of the late device/driver match. As a result, matched IDs (inclusive of requested ones) are preserved when the handoff from the early platform code happens at kobject initialization time. Since we still require kmalloc slabs to be available at this point, using kstrdup() for establishing the init_name works fine. This subsequently needs to be tested from dev_name() prior to the init_name being cleared by the driver core. We don't kfree() since others will already have a handle on the string long before the kobject initialization takes place. This is also needed to permit drivers to use the clock framework early, without having to manually construct their own device IDs from the match id/name pair locally (needed by the early console and timer code on sh and arm).

This patch creates the device_lock/unlock/trylock() functions, and converts all in-tree users to them.

Sysfs adds to the normal number of places where the vfs inode is updated by also updatng the vfs inode in sysfs_refresh_inode. Typically the inode mutex is used to serialize updates to the vfs inode, but grabbing the inode mutex in sysfs_permission and sysfs_getattr causes deadlocks, because sometimes the vfs calls those operations with the inode mutex held. Therefore sysfs can not use the inode mutex to serial updates to the vfs inode. The sysfs_mutex is acquired in all of the routines where sysfs updates the vfs inode, and with a small change we can consistently protext sysfs vfs inode updates with the sysfs_mutex. To protect the sysfs vfs inode updates with the sysfs_mutex simply requires extending the scope of sysfs_mutex in sysfs_setattr over inode_setattr, and over inode_change_ok (so we have an unchanging inode when we perform the check).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ben Nizette, the author of this driver, told me in a private mail that this project has been cancelled. He suggested to remove the driver for now, and will come back with a new version should the hardware really exist. This patch completely removes the driver. Signed-off-by: Hans J.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Two trivial fixes for the Userspace IO Kconfig file: 1) uio_sercos3 is a PCI driver, so let it depend on PCI. 2) "default n" under UIO_PCI_GENERIC is luxury since it is already the default.

| | * UIO: Add a driver for Hilscher netX-based fieldbus cardsHans J. Koch2010-03-083-0/+184
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a Userspace IO driver for netX-based fieldbus cards by Hilscher (see http://www.hilscher.com). ATM, cifX and comX cards are supported. The userspace part for this driver is provided by Hilscher and should come with the card. The driver is in use for several months now and has been tested by people at Hilscher and Linutronix. Signed-off-by: Hans J.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A pointer to cfag12864bfb_probe is passed to the core via platform_driver_register and so the function must not disappear when the .init sections are discarded. Otherwise (if also having HOTPLUG=y) unbinding and binding a device to the driver via sysfs will result in an oops as does a device being registered late. An alternative to this patch is using platform_driver_probe instead of platform_driver_register plus removing the pointer to the probe function from the struct platform_driver.
