9c940bbe2b clk: s2mps11: Add used attribute to s2mps11_dt_match
Clang warns after commit 8985167ecf57 ("clk: s2mps11: Fix matching when
built as module and DT node contains compatible"):

drivers/clk/clk-s2mps11.c:242:34: warning: variable 's2mps11_dt_match'
is not needed and will not be emitted [-Wunneeded-internal-declaration]
static const struct of_device_id s2mps11_dt_match[] = {
                                 ^
1 warning generated.

This warning happens when a variable is used in some construct that
doesn't require a reference to that variable to be emitted in the symbol
table; in this case, it's MODULE_DEVICE_TABLE, which only needs to hold
the data of the variable, not the variable itself.

$ nm -S drivers/clk/clk-s2mps11.o | rg s2mps11_dt_match
00000078 000003d4 R __mod_of__s2mps11_dt_match_device_table

Normally, with device ID table variables, it means that the variable
just needs to be tied to the device declaration at the bottom of the
file, like s2mps11_clk_id:

$ nm -S drivers/clk/clk-s2mps11.o | rg s2mps11_clk_id
00000000 00000078 R __mod_platform__s2mps11_clk_id_device_table
00000000 00000078 r s2mps11_clk_id

However, because the comment above this deliberately doesn't want this
variable added to .of_match_table, we need to mark s2mps11_dt_match as
__used to silence this warning. This makes it clear to Clang that the
variable is used for something, even if a reference to it isn't being
emitted.

77612720a2 clk: qcom: Add safe switch hook for krait mux clocks
When the Hfplls are reprogrammed during the rate change,
the primary muxes which are sourced from the same hfpll
for higher frequencies, needs to be switched to the 'safe
secondary mux' as the parent for that small window. This
is done by registering a clk notifier for the muxes and
switching to the safe parent in the PRE_RATE_CHANGE notifier
and back to the original parent in the POST_RATE_CHANGE notifier.

The Krait CPU clocks are made up of a primary mux and secondary
mux for each CPU and the L2, controlled via cp15 accessors. For
Kraits within KPSSv1 each secondary mux accepts a different aux
source, but on KPSSv2 each secondary mux accepts the same aux
source.

4d7dc77bab clk: qcom: Add support for Krait clocks
The Krait clocks are made up of a series of muxes and a divider
that choose between a fixed rate clock and dedicated HFPLLs for
each CPU. Instead of using mmio accesses to remux parents, the
Krait implementation exposes the remux control via cp15
registers. Support these clocks.

c1e4580a1d clk: at91: generated: set audio_pll_allowed in at91_clk_register_generated()
Set gck->audio_pll_allowed in at91_clk_register_generated. This makes it
easier to do it from code that is not parsing device tree.

Also, this fixes an issue where the resulting clk_hw can be dereferenced
before being tested for error.

7fa75007b7 clk: at91: audio-pll: fix audio pmc type
The allocation for the audio pmc is using the size of struct clk_audio_pad
instead of struct clk_audio_pmc. This works fine because the former is
larger than the latter but it is safer to be correct.

0d09e668b7 clk: imx7d: remove CLK_IS_CRITICAL flag for arm_a7_root_clk
i.MX7D uses virtual cpu clock of "arm" clock to be child clock

665636b294 clk: rockchip: Fix static checker warning in rockchip_ddrclk_get_parent call
Fixes the signedness bug returning '(-22)' on the return type by removing the
sanity checker in rockchip_ddrclk_get_parent(). The function should return
and unsigned value only and it's safe to remove the sanity checker as the
core functions that call get_parent like clk_core_get_parent_by_index already
ensures the validity of the clk index returned (index >= core->num_parents).

480d99fdc3 clk: mvebu: armada-37xx-tbg: Switch to clk_get and balance it in probe
The parent clock is get only to have its name, and then the clock is no
more used, so we can safely free it using clk_put. Furthermore as between
the successful devm_clk_get() and the devm_clk_put() call we don't exit
the probe function in error so I can use non managed version of clk_get()
and clk_put().
