| * powerpc/fsl: proliferate simple-bus compatibility to soc nodesKim Phillips2008-07-2931-10/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | add simple-bus compatible property to soc nodes for 83xx/85xx platforms that were missing them. Add same to platform probe code. This fixes SoC device drivers (such as talitos) to succeed in matching devices present in the soc node. also update mpc836x_rdk dts to new SEC bindings (overlooked in commit 3fd4473: powerpc/fsl: update crypto node definition and device tree instances).

| * Documentation: remove old sbc8260 board specific informationPaul Gortmaker2008-07-282-199/+0
| | | | | | | | | | | | | | | | | | | | | | This file contains 8 yr. old board specific information that was for the now gone ppc implementation, and it pre-dates widespread u-boot support. Any of the technical details of the board memory map would be more appropriately captured in a dts if I revive it as powerpc anyway.

| * cpm2: Rework baud rate generators configuration to support external clocks.Laurent Pinchart2008-07-282-43/+37
| | | | | | | | | | | | | | | | | | | | | | The CPM2 BRG setup functions cpm_setbrg and cpm2_fastbrg don't support external clocks. This patch adds a new exported __cpm2_setbrg function that takes the clock rate and clock source as extra parameters, and moves cpm_setbrg and cpm2_fastbrg to include/asm-powerpc/cpm2.h where they become inline wrappers around __cpm2_setbrg.

| * powerpc: rtc_cmos_setup: assign interrupts only if there is i8259 PICAnton Vorontsov2008-07-281-6/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | i8259 PIC is disabled on MPC8610HPCD boards, thus currently rtc-cmos driver fails to probe. To fix the issue, we lookup the device tree for "chrp,iic" and "pnpPNP,000" compatible devices, and if not found we do not assign RTC IRQ and assuming that i8259 was disabled. Though this patch fixes RTC on some boards (and surely should not break any other), the whole approach is still broken. We can't easily fix this though, because old device trees do not specify i8259 interrupts for the cmos rtc node.

| * cpm_uart: Add generic clock API support to set baudratesLaurent Pinchart2008-07-283-7/+21
| | | | | | | | | | | | | | | | | | | | This patch introduces baudrate setting support via the generic clock API. When present the optional device tree clock property is used instead of fsl-cpm-brg. Platforms can then define complex clock schemes, to output the serial clock on an external pin for instance.

| | | | | | | | | | | | | | | | | | | | | | | | This patch replaces the get_mctrl/set_mctrl stubs with modem control line read/write access through the GPIO lib. Available modem control lines are described in the device tree using GPIO bindings. The driver expect a GPIO pin for each of the CTS, RTS, DCD, DSR, DTR and RI signals. Unused control lines can be left out. Signed-off-by: Laurent Pinchart <laurentp@cse-semaphore.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| * | lguest: turn Waker into a thread, not a processRusty Russell2008-07-291-63/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | lguest uses a Waker process to break it out of the kernel (ie. actually running the guest) when file descriptor needs attention. Changing this from a process to a thread somewhat simplifies things: it can directly access the fd_set of things to watch. More importantly, it means that the Waker can see Guest memory correctly, so /dev/vring file descriptors will work as anticipated (the alternative is to actually mmap MAP_SHARED, but you can't do that with /dev/zero).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the correct timeout value varies, use a heuristic which adjusts the timeout depending on how many packets we've seen.

However their implementation is nearly identical. Refactor out common code to be reused by them. Signed-off-by: Dmitry Baryshkov <dbaryshkov@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
| * | | | | | | PCI: add D3 power state avoidance quirkAlan Cox2008-07-283-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Libata has some hacks to deal with certain controllers going silly in D3 state. The right way to handle this is to keep a PCI device flag for such devices. That can then be generalised for no ATA devices with power problems.

| * | | | | | | PCI: fix bogus "'device' may be used uninitialized" warning in pci_slotMatthew Wilcox2008-07-281-11/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I get warnings about 'device' possibly being used uninitialised. While I can deduce this is not true, it seems that GCC can't. This patch changes `check_slot' to return device on success and -1 on error, which shuts GCC up.
