/*
* LPC32XX CPU and system power management
*
* The LPC32XX has three CPU modes for controlling system power: run,
* direct-run, and halt modes. When switching between halt and run modes,
* the CPU transistions through direct-run mode. For Linux, direct-run
* mode is not used in normal operation. Halt mode is used when the
* system is fully suspended.
*
* Run mode:
* The ARM CPU clock (HCLK_PLL), HCLK bus clock, and PCLK bus clocks are
* derived from the HCLK PLL. The HCLK and PCLK bus rates are divided from
* the HCLK_PLL rate. Linux runs in this mode.
*
* Direct-run mode:
* The ARM CPU clock, HCLK bus clock, and PCLK bus clocks are driven from
* SYSCLK. SYSCLK is usually around 13MHz, but may vary based on SYSCLK
* source or the frequency of the main oscillator. In this mode, the
* HCLK_PLL can be safely enabled, changed, or disabled.
*
* Halt mode:
* SYSCLK is gated off and the CPU and system clocks are halted.
* Peripherals based on the 32KHz oscillator clock (ie, RTC, touch,
* key scanner, etc.) still operate if enabled. In this state, an enabled
* system event (ie, GPIO state change, RTC match, key press, etc.) will
* wake the system up back into direct-run mode.
*
* DRAM refresh
* DRAM clocking and refresh are slightly different for systems with DDR
* DRAM or regular SDRAM devices. If SDRAM is used in the system, the
* SDRAM will still be accessible in direct-run mode. In DDR based systems,
* a transition to direct-run mode will stop all DDR accesses (no clocks).
* Because of this, the code to switch power modes and the code to enter
* and exit DRAM self-refresh modes must not be executed in DRAM. A small
* section of IRAM is used instead for this.
*
* Suspend is handled with the following logic:
* Backup a small area of IRAM used for the suspend code
* Copy suspend code to IRAM
* Transfer control to code in IRAM
* Places DRAMs in self-refresh mode
* Enter direct-run mode
* Save state of HCLK_PLL PLL
* Disable HCLK_PLL PLL
* Enter halt mode - CPU and buses will stop
* System enters direct-run mode when an enabled event occurs
* HCLK PLL state is restored
* Run mode is entered
* DRAMS are placed back into normal mode
* Code execution returns from IRAM
* IRAM code are used for suspend is restored
* Suspend mode is exited

*
* Notes on locking
* ----------------
*
* The following locks and mutexes are used by kmemleak:
*
* - kmemleak_lock (rwlock): protects the object_list modifications and
* accesses to the object_tree_root. The object_list is the main list
* holding the metadata (struct kmemleak_object) for the allocated memory
* blocks. The object_tree_root is a red black tree used to look-up
* metadata based on a pointer to the corresponding memory block. The
* kmemleak_object structures are added to the object_list and
* object_tree_root in the create_object() function called from the
* kmemleak_alloc() callback and removed in delete_object() called from the
* kmemleak_free() callback
* - kmemleak_object.lock (spinlock): protects a kmemleak_object. Accesses to
* the metadata (e.g. count) are protected by this lock. Note that some
* members of this structure may be protected by other means (atomic or
* kmemleak_lock). This lock is also held when scanning the corresponding
* memory block to avoid the kernel freeing it via the kmemleak_free()
* callback. This is less heavyweight than holding a global lock like
* kmemleak_lock during scanning
* - scan_mutex (mutex): ensures that only one thread may scan the memory for
* unreferenced objects at a time. The gray_list contains the objects which
* are already referenced or marked as false positives and need to be
* scanned. This list is only modified during a scanning episode when the
* scan_mutex is held. At the end of a scan, the gray_list is always empty.
* Note that the kmemleak_object.use_count is incremented when an object is
* added to the gray_list and therefore cannot be freed. This mutex also
* prevents multiple users of the "kmemleak" debugfs file together with
* modifications to the memory scanning parameters including the scan_thread
* pointer
*
* Locks and mutexes are acquired/nested in the following order:
*
* scan_mutex [-> object->lock] -> kmemleak_lock -> other_object->lock (SINGLE_DEPTH_NESTING)
*
* No kmemleak_lock and object->lock nesting is allowed outside scan_mutex
* regions.
*
* The kmemleak_object structures have a use_count incremented or decremented
* using the get_object()/put_object() functions. When the use_count becomes
* 0, this count can no longer be incremented and put_object() schedules the
* kmemleak_object freeing via an RCU callback. All calls to the get_object()
* function must be protected by rcu_read_lock() to avoid accessing a freed
* structure.

* option is available.
*
* __GFP_KSWAPD_RECLAIM indicates that the caller wants to wake kswapd when
* the low watermark is reached and have it reclaim pages until the high
* watermark is reached. A caller may wish to clear this flag when fallback
* options are available and the reclaim is likely to disrupt the system. The
* canonical example is THP allocation where a fallback is cheap but
* reclaim/compaction may cause indirect stalls.
*
* __GFP_RECLAIM is shorthand to allow/forbid both direct and kswapd reclaim.
*
* __GFP_REPEAT: Try hard to allocate the memory, but the allocation attempt
* _might_ fail. This depends upon the particular VM implementation.
*
* __GFP_NOFAIL: The VM implementation _must_ retry infinitely: the caller
* cannot handle allocation failures. New users should be evaluated carefully
* (and the flag should be used only when there is no reasonable failure
* policy) but it is definitely preferable to use the flag rather than
* opencode endless loop around allocator.
*
* __GFP_NORETRY: The VM implementation must not retry indefinitely and will
* return NULL when direct reclaim and memory compaction have failed to allow
* the allocation to succeed. The OOM killer is not called with the current
* implementation.

* Useful GFP flag combinations that are commonly used. It is recommended
* that subsystems start with one of these combinations and then set/clear
* __GFP_FOO flags as necessary.
*
* GFP_ATOMIC users can not sleep and need the allocation to succeed. A lower
* watermark is applied to allow access to "atomic reserves"
*
* GFP_KERNEL is typical for kernel-internal allocations. The caller requires
* ZONE_NORMAL or a lower zone for direct access but can direct reclaim.
*
* GFP_KERNEL_ACCOUNT is the same as GFP_KERNEL, except the allocation is
* accounted to kmemcg.
*
* GFP_NOWAIT is for kernel allocations that should not stall for direct
* reclaim, start physical IO or use any filesystem callback.
*
* GFP_NOIO will use direct reclaim to discard clean pages or slab pages
* that do not require the starting of any physical IO.
*
* GFP_NOFS will use direct reclaim but will not use any filesystem interfaces.
*
* GFP_USER is for userspace allocations that also need to be directly
* accessibly by the kernel or hardware. It is typically used by hardware
* for buffers that are mapped to userspace (e.g. graphics) that hardware
* still must DMA to. cpuset limits are enforced for these allocations.
*
* GFP_DMA exists for historical reasons and should be avoided where possible.
* The flags indicates that the caller requires that the lowest zone be
* used (ZONE_DMA or 16M on x86-64). Ideally, this would be removed but
* it would require careful auditing as some users really require it and
* others use the flag to avoid lowmem reserves in ZONE_DMA and treat the
* lowest zone as a type of emergency reserve.
*
* GFP_DMA32 is similar to GFP_DMA except that the caller requires a 32-bit
* address.
*
* GFP_HIGHUSER is for userspace allocations that may be mapped to userspace,
* do not need to be directly accessible by the kernel but that cannot
* move once in use. An example may be a hardware allocation that maps
* data directly into userspace but has no addressing limitations.
*
* GFP_HIGHUSER_MOVABLE is for userspace allocations that the kernel does not
* need direct access to but can use kmap() when access is required. They
* are expected to be movable via page reclaim or page migration. Typically,
* pages on the LRU would also be allocated with GFP_HIGHUSER_MOVABLE.
*
* GFP_TRANSHUGE and GFP_TRANSHUGE_LIGHT are used for THP allocations. They are
* compound allocations that will generally fail quickly if memory is not
* available and will not wake kswapd/kcompactd on failure. The _LIGHT
* version does not attempt reclaim/compaction at all and is by default used
* in page fault path, while the non-light is used by khugepaged.
