+  * NEON doesn't have a rotate instruction.  The alternatives are, more or less:
+  *
+  * (a)  vshl.u32 + vsri.u32		(needs temporary register)
+  * (b)  vshl.u32 + vshr.u32 + vorr	(needs temporary register)
+  * (c)  vrev32.16			(16-bit rotations only)
+  * (d)  vtbl.8 + vtbl.8		(multiple of 8 bits rotations only,
+  *					 needs index vector)
+  *
+  * ChaCha20 has 16, 12, 8, and 7-bit rotations.  For the 12 and 7-bit
+  * rotations, the only choices are (a) and (b).  We use (a) since it takes
+  * two-thirds the cycles of (b) on both Cortex-A7 and Cortex-A53.
+  *
+  * For the 16-bit rotation, we use vrev32.16 since it's consistently fastest
+  * and doesn't need a temporary register.
+  *
+  * For the 8-bit rotation, we use vtbl.8 + vtbl.8.  On Cortex-A7, this sequence
+  * is twice as fast as (a), even when doing (a) on multiple registers
+  * simultaneously to eliminate the stall between vshl and vsri.  Also, it
+  * parallelizes better when temporary registers are scarce.
+  *
+  * A disadvantage is that on Cortex-A53, the vtbl sequence is the same speed as
+  * (a), so the need to load the rotation table actually makes the vtbl method
+  * slightly slower overall on that CPU (~1.3% slower ChaCha20).  Still, it
+  * seems to be a good compromise to get a more significant speed boost on some
+  * CPUs, e.g. ~4.8% faster ChaCha20 on Cortex-A7.

+ * ARM VMSAv8-64 defines an algorithm for finding the translation table
+ * descriptors in section D4.2.8 in ARM DDI 0487C.a.
+ *
+ * The algorithm defines the expectations on the translation table
+ * addresses for each level, based on PAGE_SIZE, entry level
+ * and the translation table size (T0SZ). The variable "x" in the
+ * algorithm determines the alignment of a table base address at a given
+ * level and thus determines the alignment of VTTBR:BADDR for stage2
+ * page table entry level.
+ * Since the number of bits resolved at the entry level could vary
+ * depending on the T0SZ, the value of "x" is defined based on a
+ * Magic constant for a given PAGE_SIZE and Entry Level. The
+ * intermediate levels must be always aligned to the PAGE_SIZE (i.e,
+ * x = PAGE_SHIFT).
+ *
+ * The value of "x" for entry level is calculated as :
+ *    x = Magic_N - T0SZ
+ *
+ * where Magic_N is an integer depending on the page size and the entry
+ * level of the page table as below:
+ *
+ *	--------------------------------------------
+ *	| Entry level		|  4K    16K   64K |
+ *	--------------------------------------------
+ *	| Level: 0 (4 levels)	| 28   |  -  |  -  |
+ *	--------------------------------------------
+ *	| Level: 1 (3 levels)	| 37   | 31  | 25  |
+ *	--------------------------------------------
+ *	| Level: 2 (2 levels)	| 46   | 42  | 38  |
+ *	--------------------------------------------
+ *	| Level: 3 (1 level)	| -    | 53  | 51  |
+ *	--------------------------------------------
+ *
+ * We have a magic formula for the Magic_N below:
+ *
+ *  Magic_N(PAGE_SIZE, Level) = 64 - ((PAGE_SHIFT - 3) * Number_of_levels)
+ *
+ * where Number_of_levels = (4 - Level). We are only interested in the
+ * value for Entry_Level for the stage2 page table.
+ *
+ * So, given that T0SZ = (64 - IPA_SHIFT), we can compute 'x' as follows:
+ *
+ *	x = (64 - ((PAGE_SHIFT - 3) * Number_of_levels)) - (64 - IPA_SHIFT)
+ *	  = IPA_SHIFT - ((PAGE_SHIFT - 3) * Number of levels)
+ *
+ * Here is one way to explain the Magic Formula:
+ *
+ *  x = log2(Size_of_Entry_Level_Table)
+ *
+ * Since, we can resolve (PAGE_SHIFT - 3) bits at each level, and another
+ * PAGE_SHIFT bits in the PTE, we have :
+ *
+ *  Bits_Entry_level = IPA_SHIFT - ((PAGE_SHIFT - 3) * (n - 1) + PAGE_SHIFT)
+ *		     = IPA_SHIFT - (PAGE_SHIFT - 3) * n - 3
+ *  where n = number of levels, and since each pointer is 8bytes, we have:
+ *
+ *  x = Bits_Entry_Level + 3
+ *    = IPA_SHIFT - (PAGE_SHIFT - 3) * n
+ *
+ * The only constraint here is that, we have to find the number of page table
+ * levels for a given IPA size (which we do, see stage2_pt_levels())

-#	STRUCT job_aes2
-#	RES_Q	.plaintext,	1
-#	RES_Q	.ciphertext,	1
-#	RES_DQ	.IV,		1
-#	RES_B	.nested,	_JOB_AES_SIZE, _JOB_AES_ALIGN
-#	RES_U	.union,		size1, align1, \
-#				size2, align2, \
-#				...
-#	ENDSTRUCT
-#	# Following only needed if nesting
-#	%assign job_aes2_size	_FIELD_OFFSET
-#	%assign job_aes2_align	_STRUCT_ALIGN
-#
-# RES_* macros take a name, a count and an optional alignment.
-# The count in in terms of the base size of the macro, and the
-# default alignment is the base size.
-# The macros are:
-# Macro    Base size
-# RES_B	    1
-# RES_W	    2
-# RES_D     4
-# RES_Q     8
-# RES_DQ   16
-# RES_Y    32
-# RES_Z    64
-#
-# RES_U defines a union. It's arguments are a name and two or more
-# pairs of "size, alignment"
-#
-# The two assigns are only needed if this structure is being nested
-# within another. Even if the assigns are not done, one can still use
-# STRUCT_NAME_size as the size of the structure.
-#
-# Note that for nesting, you still need to assign to STRUCT_NAME_size.
-#
-# The differences between this and using "struc" directly are that each
-# type is implicitly aligned to its natural length (although this can be
-# over-ridden with an explicit third parameter), and that the structure
-# is padded at the end to its overall alignment.

-# RES_* macros take a name, a count and an optional alignment.
-# The count in in terms of the base size of the macro, and the
-# default alignment is the base size.
-# The macros are:
-# Macro    Base size
-# RES_B	    1
-# RES_W	    2
-# RES_D     4
-# RES_Q     8
-# RES_DQ   16
-# RES_Y    32
-# RES_Z    64
-#
-# RES_U defines a union. It's arguments are a name and two or more
-# pairs of "size, alignment"
-#
-# The two assigns are only needed if this structure is being nested
-# within another. Even if the assigns are not done, one can still use
-# STRUCT_NAME_size as the size of the structure.
-#
-# Note that for nesting, you still need to assign to STRUCT_NAME_size.
-#
-# The differences between this and using "struc" directly are that each
-# type is implicitly aligned to its natural length (although this can be
-# over-ridden with an explicit third parameter), and that the structure
-# is padded at the end to its overall alignment.

-#       RES_Q   .plaintext,     1
-#       RES_Q   .ciphertext,    1
-#       RES_DQ  .IV,            1
-#       RES_B   .nested,        _JOB_AES_SIZE, _JOB_AES_ALIGN
-#       RES_U   .union,         size1, align1, \
-#                               size2, align2, \
-#                               ...
-#       ENDSTRUCT
-#       # Following only needed if nesting
-#       %assign job_aes2_size   _FIELD_OFFSET
-#       %assign job_aes2_align  _STRUCT_ALIGN
-#
-# RES_* macros take a name, a count and an optional alignment.
-# The count in in terms of the base size of the macro, and the
-# default alignment is the base size.
-# The macros are:
-# Macro    Base size
-# RES_B     1
-# RES_W     2
-# RES_D     4
-# RES_Q     8
-# RES_DQ   16
-# RES_Y    32
-# RES_Z    64
-#
-# RES_U defines a union. It's arguments are a name and two or more
-# pairs of "size, alignment"
-#
-# The two assigns are only needed if this structure is being nested
-# within another. Even if the assigns are not done, one can still use
-# STRUCT_NAME_size as the size of the structure.
-#
-# Note that for nesting, you still need to assign to STRUCT_NAME_size.
-#
-# The differences between this and using "struc" directly are that each
-# type is implicitly aligned to its natural length (although this can be
-# over-ridden with an explicit third parameter), and that the structure
-# is padded at the end to its overall alignment.

+ * This function blocks P-Unit accesses to the PMIC I2C bus, so that kernel

+ *
+ * This function may be called by I2C controller code while an I2C driver has
+ * already blocked P-Unit accesses because it wants them blocked over multiple
+ * i2c-transfers, for e.g. read-modify-write of an I2C client register.
+ *
+ * The P-Unit accesses already being blocked is tracked through the
+ * iosf_mbi_block_punit_i2c_access_count variable which is protected by the
+ * iosf_mbi_block_punit_i2c_access_count_mutex this mutex is hold for the
+ * entire duration of the function.
+ *
+ * If access is not blocked yet, this function takes the following steps:
+ *
+ * 1) Some code sends request to the P-Unit which make it access the PMIC
+ *    I2C bus. Testing has shown that the P-Unit does not check its internal
+ *    PMIC bus semaphore for these requests. Callers of these requests call
+ *    iosf_mbi_punit_acquire()/_release() around their P-Unit accesses, these
+ *    functions lock/unlock the iosf_mbi_punit_mutex.
+ *    As the first step we lock the iosf_mbi_punit_mutex, to wait for any in
+ *    flight requests to finish and to block any new requests.
+ *
+ * 2) Some code makes such P-Unit requests from atomic contexts where it
+ *    cannot call iosf_mbi_punit_acquire() as that may sleep.
+ *    As the second step we call a notifier chain which allows any code
+ *    needing P-Unit resources from atomic context to acquire them before
+ *    we take control over the PMIC I2C bus.
+ *
+ * 3) When CPU cores enter C6 or C7 the P-Unit needs to talk to the PMIC
+ *    if this happens while the kernel itself is accessing the PMIC I2C bus
+ *    the SoC hangs.
+ *    As the third step we call pm_qos_update_request() to disallow the CPU
+ *    to enter C6 or C7.
+ *
+ * 4) The P-Unit has a PMIC bus semaphore which we can request to stop
+ *    autonomous P-Unit tasks from accessing the PMIC I2C bus while we hold it.
+ *    As the fourth and final step we request this semaphore and wait for our
+ *    request to be acknowledged.
