The DTPM framework will evolve in the next cycles. Let's add a
temporary EXPERIMENTAL tag to the option so users will be aware
the API may change over time.

powercap/drivers/dtpm: Fix root node initialization2021-03-01T16:43:29ZDaniel Lezcanodaniel.lezcano@linaro.org2021-02-24T18:30:21Zurn:sha1:f3c141057976120148ca32d9d030a2256a5ffb7b
The root node is not set to NULL when the dtpm root node is
removed. Consequently, it is not possible to create a new root
as it is already set.
Set the root node to NULL when the last node is removed.

It's not a good idea to access the phys_proc_id of cpuinfo directly.
Use topology_physical_package_id(cpu) instead.

powercap/drivers/dtpm: Fix size of object being allocated2021-01-07T17:16:03ZColin Ian Kingcolin.king@canonical.com2021-01-04T12:10:53Zurn:sha1:66e713fbbbc6c259559d4937a3b016d36ab529ff
The kzalloc allocation for dtpm_cpu is currently allocating the size
of the pointer and not the size of the structure. Fix this by using
the correct sizeof argument.
Addresses-Coverity: ("Wrong sizeof argument")

The powercap_register_control_type() function never returns NULL, it
returns error pointers on error so update this check.

powercap/drivers/dtpm: Fix a double shift bug2021-01-07T17:13:51ZDan Carpenterdan.carpenter@oracle.com2021-01-06T08:36:35Zurn:sha1:2185c23071e2c1f26fbccb323aa831732540cfcc
The DTPM_POWER_LIMIT_FLAG is used for test_bit() etc which take a bit
number so it should be bit 0. But currently it's set to BIT(0) then
that is double shifted equivalent to BIT(BIT(0)). This doesn't cause a
run time problem because it's done consistently.

powercap/drivers/dtpm: Fix __udivdi3 and __aeabi_uldivmod unresolved symbols2020-12-30T17:47:33ZDaniel Lezcanodaniel.lezcano@linaro.org2020-12-30T15:37:44Zurn:sha1:8f50db4b5c79af2ba54f5fbe8a5173fd7f37a493
32-bit architectures do not support u64 divisions, so the macro
DIV_ROUND_CLOSEST is not adequate as the compiler will replace the
call to an unexisting function for the platform, leading to
unresolved references to symbols.
Fix this by using the compatible macros:
DIV64_U64_ROUND_CLOSEST and DIV_ROUND_CLOSEST_ULL.
