2012-11-08ARM: OMAP2+: PRCM: remove obsolete prcm.[ch]Paul Walmsley
arch/arm/mach-omap2/prcm.c and arch/arm/plat-omap/include/plat/prcm.h are now completely unused and can be removed. Signed-off-by: Paul Walmsley <paul@pwsan.com> Tested-by: Vaibhav Hiremath <hvaibhav@ti.com>
2012-11-08ARM: OMAP2+: hwmod: call to _omap4_disable_module() should use the ↵Paul Walmsley
SoC-specific call The hwmod code unconditionally calls _omap4_disable_module() on all SoCs when a module doesn't enable correctly. This "worked" due to the weak function omap4_cminst_wait_module_idle() in arch/arm/mach-omap2/prcm.c, which was a no-op. But now those weak functions are going away - they should not be used. So this patch will now call the SoC-specific disable_module code, assuming it exists. Needs to be done before the weak function is removed, otherwise AM33xx will crash early in boot.

2012-11-08ARM: OMAP2+: PRCM: split and relocate the PRM/CM globals setupPaul Walmsley
Split omap2_set_globals_prcm() into PRM, CM, and PRCM_MPU variants, since these are all separate IP blocks. This should make it easier to move the PRM, CM, PRCM_MPU code into drivers/ in future patchsets. At this point arch/arm/plat-omap/include/plat/prcm.h is empty; a subsequent patch will remove it, and remove the #include from all the files that #include it.

2012-11-08ARM: OMAP2+: CM/clock: convert _omap2_module_wait_ready() to use ↵Paul Walmsley
SoC-independent CM functions Convert the OMAP clock code's _omap2_module_wait_ready() to use SoC-independent CM functions that are provided by the CM code, rather than using a deprecated function from mach-omap2/prcm.c. This facilitates the future conversion of the CM code to a driver, and also removes a mach-omap2/prcm.c user. mach-omap2/prcm.c will be removed by a subsequent patch. Some modules have IDLEST registers that aren't in the CM module, such as the AM3517 IDLEST bits. So we also need a fallback function for these non-CM odd cases. Create a temporary one in mach-omap2/clock.c, intended to exist until the SCM drivers are ready. Signed-off-by: Paul Walmsley <paul@pwsan.com> Tested-by: Vaibhav Hiremath <hvaibhav@ti.com>

Convert the OMAP2xxx APLL code to use omap2_cm_wait_module_ready(), and move the low-level CM register manipulation functions to mach-omap2/cm2xxx.c. The objectives here are to remove the dependency on the deprecated omap2_cm_wait_idlest() function in mach-omap2/prcm.c, so that code can be removed later; and move low-level register accesses to the CM IP block to the CM code, which will soon be moved into drivers/.

Modify the board files to use the SoC-specific system restart functions. At this point it's possible to remove omap_prcm_restart() from mach-omap2/prcm.c. While removing the prototypes for the now-unused restart functions, clean up a few more obsolete prototypes in mach-omap2/clock.h.

2012-11-08ARM: OMAP2+: PRCM: create SoC-specific chip restart functionsPaul Walmsley
Split omap_prcm_restart() from mach-omap2/prcm.c into SoC-specific variants. These functions need to be able to save the reboot reason into the scratchpad RAM. This implies a dependency on both the PRM and SCM IP blocks, so they've been moved into their own file. This will eventually call functions in the PRM and SCM drivers, once those are created. Vaibhav Hiremath <hvaibhav@ti.com> identified an unused prototype in the first version of this patch - now removed. Tony Lindgren <tony@atomide.com> noted a compile problem with some RMK Kconfigs; resolved in this patch.

2012-11-08ARM: OMAP2xxx: clock: remove global 'dclk' variablePaul Walmsley
Remove the global 'dclk' variable, instead replacing it with a variable local to the dpllcore clock type C file. This removes some of the special-case code surrounding the OMAP2xxx clock init. This patch is a prerequisite for the removal of the omap_prcm_restart() code from arch/arm/mach-omap2/prcm.c. It also cleans up some special-case OMAP2xxx clock code in the process.

Add SoC reset functions into the PRM code. These functions are based on code from mach-omap2/prcm.c. They reset the SoC using the CORE DPLL reset method (as opposed to one of the other two or three chip reset methods). Adding them here will facilitate their removal from arch/arm/mach-omap2/prcm.c.

2012-10-29ARM: OMAP2+: WDT: move init; add read_reset_sources pdata function pointerPaul Walmsley
The OMAP watchdog timer driver directly calls a function exported by code in arch/arm/mach-omap2. This is not good; it tightly couples this driver to the mach-omap2 integration code. Instead, add a temporary platform_data function pointer to abstract this function call. A subsequent patch will convert the watchdog driver to use this function pointer. This patch also moves the device creation code out of arch/arm/mach-omap2/devices.c and into arch/arm/mach-omap2/wd_timer.c. This is another step towards the removal of arch/arm/mach-omap2/devices.c.

2012-10-21ARM: OMAP2+: PRM: create PRM reset source API for the watchdog timer driverPaul Walmsley
The OMAP watchdog timer driver needs to determine what caused the SoC to reset for its GETBOOTSTATUS ioctl. So, define a set of standard reset sources across OMAP SoCs. For OMAP2xxx, 3xxx, and 4xxx SoCs, define mappings from the SoC-specific reset source register bits to the standardized reset source IDs. Create SoC-specific PRM functions that read the appropriate per-SoC register and use the mapping to return the standardized reset bits. Register the SoC-specific PRM functions with the common PRM code via prm_register(). Create a function in the common PRM code, prm_read_reset_sources(), that calls the SoC-specific function, registered during boot. This patch does not yet handle some SoCs, such as AM33xx. Those SoCs were not handled by the code this will replace. Signed-off-by: Paul Walmsley <paul@pwsan.com>
2012-10-21ARM: OMAP1: create read_reset_sources() function (for initial use by watchdog)Paul Walmsley
On OMAP1, the existing OMAP watchdog driver reads a register directly from a non-watchdog IP block. It also does not convert the register's contents into the standard WDIOF_* bits expected from the GETBOOTSTATUS ioctl(). To move towards fixing these problems, create an function in arch/arm/mach-omap1 to return the reset source data. A subsequent patch will provide this function to the watchdog driver via platform_data. In the long term, the best approach would be to move this function to a new OMAP1 driver that handles access to the OMAP1 Clock Generation and Reset Management IP block. Then no platform_data would be needed. Signed-off-by: Paul Walmsley <paul@pwsan.com>
2012-10-21ARM: OMAP2+: CM: prepare for use of cm_ll_data function pointersPaul Walmsley
There are several CM operations which behave similarly across OMAP2+ SoCs, but which have slight differences in their underlying implementations. This patch creates the support code for this function pointer registration process. No function pointers are included yet, but a subsequent patch will create these for the module IDLEST registers. This patch allows other code to use CM-provided data and operations without needing to know which SoC is currently in use. A further description of the concept is provided in the patch entitled "ARM: OMAP2+: PRM: prepare for use of prm_ll_data function pointers". Signed-off-by: Paul Walmsley <paul@pwsan.com>
2012-10-21ARM: OMAP2+: PRM: prepare for use of prm_ll_data function pointersPaul Walmsley
There are several PRM operations which behave similarly across OMAP2+ SoCs, but which have slight differences in their underlying implementations. For example, to fetch the SoC's last reset sources, different registers are read across OMAP2xxx, 3xxx, and 44xx, and different bits are used on each SoC. But the information returned is so similar that a single, common interface for drivers is useful. This patch creates the support code for this function pointer registration process. No function pointers are included yet, but a subsequent patch will create one for the reset source API. To illustrate the end goal with the above reset source example, each per-SoC driver will use its own low-level implementation function -- e.g., prm2xxx.c would contain omap2xxx_prm_read_reset_sources(). This function would read the appropriate register and remap the register bits to a standard set of reset source bits. When the prm2xxx.c driver is loaded, it would register this function with the common PRM driver, prm.c. prm.c would then export a common function, omap_prm_read_reset_sources(). Calling it would call through to the function pointer for the currently-registered SoC PRM driver. This will allow other drivers to use PRM-provided data and operations without needing to know which SoC is currently in use. Signed-off-by: Paul Walmsley <paul@pwsan.com>

2012-10-20arm64: fix alignment padding in assembly codeMarc Zyngier
An interesting effect of using the generic version of linkage.h is that the padding is defined in terms of x86 NOPs, which can have even more interesting effects when the assembly code looks like this: ENTRY(func1) mov x0, xzr ENDPROC(func1) // fall through ENTRY(func2) mov x0, #1 ret ENDPROC(func2) Admittedly, the code is not very nice. But having code from another architecture doesn't look completely sane either. The fix is to add arm64's version of linkage.h, which causes the insertion of proper AArch64 NOPs.

git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent Pull perf/urgent fixes from Arnaldo Carvalho de Melo: * The python binding needs to link with libtraceevent and to initialize the 'page_size' variable so that mmaping works again. * The callchain folding character that appears on the TUI just before the overhead had disappeared due to recent changes, add it back. * Intel PEBS in VT-x context uses the DS address as a guest linear address, even though its programmed by the host as a host linear address. This either results in guest memory corruption and or the hardware faulting and 'crashing' the virtual machine. Therefore we have to disable PEBS on VT-x enter and re-enable on VT-x exit, enforcing a strict exclude_guest. Kernel side enforcement fix by Peter Zijlstra, tooling side fix by David Ahern. * Fix build on sparc due to UAPI, fix from David Miller. * Fixes for the srclike sort key for unresolved symbols and when processing samples in JITted code, where we don't have an ELF file, just an special symbol table, fixes from Namhyung Kim. * Fix some leaks in libtraceevent, from Steven Rostedt.
