* mv643xx_eth: Place explicit port number in mv643xx_eth_platform_dataDale Farnsworth2007-03-061-0/+2
| | | | | | | | | | | | | | We were using the platform_device.id field to identify which ethernet port is used for mv643xx_eth device. This is not generally correct. It will be incorrect, for example, if a hardware platform uses a single port but not the first port. Here, we add an explicit port_number field to struct mv643xx_eth_platform_data. This makes the mv643xx_eth_platform_data structure required, but that isn't an issue since all users currently provide it already.

* [PATCH] msi: sanely support hardware level msi disablingEric W. Biederman2007-03-051-1/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | In some cases when we are not using msi we need a way to ensure that the hardware does not have an msi capability enabled. Currently the code has been calling disable_msi_mode to try and achieve that. However disable_msi_mode has several other side effects and is only available when msi support is compiled in so it isn't really appropriate. Instead this patch implements pci_msi_off which disables all msi and msix capabilities unconditionally with no additional side effects. pci_disable_device was redundantly clearing the bus master enable flag and clearing the msi enable bit. A device that is not allowed to perform bus mastering operations cannot generate intx or msi interrupt messages as those are essentially a special case of dma, and require bus mastering. So the call in pci_disable_device to disable msi capabilities was redundant. quirk_pcie_pxh also called disable_msi_mode and is updated to use pci_msi_off. Signed-off-by: Eric W.

* backlight: Separate backlight properties from backlight ops pointersRichard Purdie2007-02-202-5/+5
| | | | | | | | | Per device data such as brightness belongs to the indivdual device and should therefore be separate from the the backlight operation function pointers. This patch splits the two types of data and allows simplifcation of some code. Signed-off-by: Richard Purdie <rpurdie@rpsys.net>
* backlight: Fix external uses of backlight internal semaphoreRichard Purdie2007-02-202-17/+6Star
| | | | | | | | | | | | | | | | | | backlight_device->sem has a very specific use as documented in the header file. The external users of this are using it for a different reason, to serialise access to the update_status() method. backlight users were supposed to implement their own internal serialisation of update_status() if needed but everyone is doing things differently and incorrectly. Therefore add a global mutex to take care of serialisation for everyone, once and for all. Locking for get_brightness remains optional since most users don't need it. Also update the lcd class in a similar way. Signed-off-by: Richard Purdie <rpurdie@rpsys.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The semantic effect of insert_at_head is that it would allow new registered sysctl entries to override existing sysctl entries of the same name. Which is pain for caching and the proc interface never implemented. I have done an audit and discovered that none of the current users of register_sysctl care as (excpet for directories) they do not register duplicate sysctl entries. So this patch simply removes the support for overriding existing entries in the sys_sysctl interface since no one uses it or cares and it makes future enhancments harder. Signed-off-by: Eric W.

| | | | | | | | | | | | | | | udbg_early_init() is a function used on 64 bit systems, which initializes whichever early udbg backend is configured. This function is not called on 32-bit, however if btext early debug is enabled it does have an explicit, inline, #ifdef-ed assignment performing analagous initialization.

* [POWERPC] Open Firmware serial port driverArnd Bergmann2007-02-141-0/+15
| | | | | | | | | | | | | | | | | This can be used for serial ports that are connected to an OF platform bus but are not autodetected by the lecacy serial support. It will automatically take over devices that come from the legacy serial detection, which usually is only one device. In some cases, rtas may be set up to use the serial port in the firmware, which allows easier debugging before probing the serial ports. In this case, the "used-by-rtas" property must be set by the firmware. This patch also adds code to the legacy serial driver to check for this.

* [POWERPC] Move MPIC smp routines into mpic.cMichael Ellerman2007-02-142-23/+21Star
| | | | | | | | Move a couple of MPIC smp routines into mpic.c, they're inside an SMP block in mpic.c - so they're still only built for SMP. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [POWERPC] Cleanup pseries kexec codeMichael Ellerman2007-02-144-48/+83
| | | | | | | | | | | | | Move all the pseries kexec code into one file, platforms/pseries/kexec.c Provide helpers for setting up ppc_md.kexec_cpu_down, so that we don't have to have #ifdef CONFIG_KEXEC in setup.c Move the initialisation of the ppc_md kexec callbacks into an init routine. This is well and truly early enough to cause no change in behaviour, we can't kexec until userspace has given us a kernel to kexec into.

* [POWERPC] Cleanup pseries smp initialisation codeMichael Ellerman2007-02-143-6/+9
| | | | | | | | | Move some extern declarations from setup.c into the new pseries.h. While we're at it, provide dummy implementations for !SMP, to avoid cluttering the C file with more #ifdefs. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
