* kdb: core for kgdb back end (1 of 2)Jason Wessel2010-05-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch contains only the kdb core. Because the change set was large, it was split. The next patch in the series includes the instrumentation into the core kernel which are mainly helper functions for kdb. This work is directly derived from kdb v4.4 found at: ftp://oss.sgi.com/projects/kdb/download/v4.4/ The kdb internals have been re-organized to make them mostly platform independent and to connect everything to the debug core which is used by gdbstub (which has long been known as kgdb). The original version of kdb was 58,000 lines worth of changes to support x86. From that implementation only the kdb shell, and basic commands for memory access, runcontrol, lsmod, and dmesg where carried forward. This is a generic implementation which aims to cover all the current architectures using the kgdb core: ppc, arm, x86, mips, sparc, sh and blackfin. More archictectures can be added by implementing the architecture specific kgdb functions.

* kgdb,sh: update superh kgdb exception handlingJason Wessel2010-05-20
| | | | | | | | | | | | | | | Implement kgdb_arch_pc() which adjusts the pc if it needs to be adjusted after a software breakpoint trap. Implement kgdb_arch_set_pc() which is a new required function in the kgdb debug core. When processing a single step return zero in the error exception field so that the debug core can distinguish between a single step trap and a breakpoint trap generically.

* Separate the gdbstub from the debug coreJason Wessel2010-05-20
| | | | | | | | | | | | | Split the former kernel/kgdb.c into debug_core.c which contains the kernel debugger exception logic and to the gdbstub.c which contains the logic for allowing gdb to talk to the debug core. This also created a private include file called debug_core.h which contains all the definitions to glue the debug_core to any other debugger connections.

The AD7142 and AD7147 can interface to external capacitance sensors implementing functions such as buttons, scrollwheels, sliders, touchpads and so on. The chips don't restrict the specific usage. Depending on the hardware connection, one special target board can include one or several these components. The platform_data for the device's "struct device" holds these information. The data-struct defined in head file descript the hardware feature of button/scrollwheel/slider/touchpad components on target boards, which need be filled in the arch/mach-/. As the result, the driver is independent of boards. It gets the components layout from the platform_data, registers related devices, fullfills the algorithms and state machines for these components and report related input events to up level.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Touch enbaled devices share the same product ID with pen. However, we do not want to post touch events while pen is in prox. To do so, we used to keep a local static variable to keep track of if pen is in prox or not. This works fine for Tablet PC devices since there is only one device attached. With the newer touch enabled regular tablets, we can not make this assumption any more, i.e, one system may have more than one identical tablet plugged in. This patch adds an new entry, shared, into the struct wacom_wac so touch data can access pen data to locally. This solution assumes the two tools (touch and pen) of the same ID will be probed one after the other without interruption in between by another Wacom device of the same ID.
