26b36df751 clk: Add generic sync_state callback for disabling unused clocks
There are unused clocks that need to remain untouched by clk_disable_unused,
and most likely could be disabled later on sync_state. So provide a generic
sync_state callback for the clock providers that register such clocks.
Then, use the same mechanism as clk_disable_unused from that generic
callback, but pass the device to make sure only the clocks belonging to
the current clock provider get disabled, if unused. Also, during the
default clk_disable_unused, if the driver that registered the clock has
the generic clk_sync_state_disable_unused callback set for sync_state,
skip disabling its clocks.

e5ca1b251d clk: qcom: smd-rpm: rename msm8992_ln_bb_* clocks to qcs404_ln_bb_*
For each of XO_BUFFER_PINCTRL clocks there is a corresponding XO_BUFFER clock
with the similar name (e.g. msm8998_ln_bb_clk3_pin vs
msm8998_ln_bb_clk3). For qcs404_ln_bb_clk_pin there is no
qcs404_ln_bb_clk, since the msm8992_ln_bb_clk was used instead (even for
qcs404 platform).

Follow the usual practice and rename msm8992_ln_bb_clk clocks to
qcs404_ln_bb_clk (and rename active-only clock in a similar way).

This is a preparation step for the next patch, which will merge
XO_BUFFER and XO_BUFFER_PINCTRL definitions.

2ce81afa0c clk: qcom: gcc-qcs404: sort out the cxo clock
The GCC driver registers the cxo clock as a thin wrapper around board's
xo_board clock. Nowadays we can use the xo_board directly in all the
clocks that use it. Use the fw_name "cxo" for this clock.

Convert the clock driver to specify parent data rather than parent
names, to actually bind using 'clock-names' specified in the DTS rather
than global clock names. Use parent_hws where possible to refer parent
clocks directly, skipping the lookup.

a613af2ccb clk: qcom: gcc-qcs404: fix the name of the HDMI PLL clock
The QCS404 uses 28nm HDMI PHY. The in-kernel driver doesn't provide the
PLL (yet), but the out of tree patches used the name "hdmi_pll" for it.
Other Qualcomm HDMI PHYs use either the name "hdmi_pll" (8960) or
"hdmipll" (8996). Thus change the expected HDMI PLL clock name to
"hdmi_pll".

On the QCS404 platform the driver for the Global Clock Controller
doens't define gpll0_out_aux and gpll4_out_aux clocks, so it's not
possible to use them as parents. Remove entries for these clocks.

Note: backporting this patch to earlier kernels would also require a

292a089d78 treewide: Convert del_timer*() to timer_shutdown*()
Due to several bugs caused by timers being re-armed after they are
shutdown and just before they are freed, a new state of timers was added
called "shutdown".  After a timer is set to this state, then it can no
longer be re-armed.

The following script was run to find all the trivial locations where
del_timer() or del_timer_sync() is called in the same function that the
object holding the timer is freed.  It also ignores any locations where
the timer->function is modified between the del_timer*() and the free(),
as that is not considered a "trivial" case.

This was created by using a coccinelle script and the following
commands:

    $ cat timer.cocci
    @@
    expression ptr, slab;
    identifier timer, rfield;
    @@
    (
    -       del_timer(&ptr->timer);
    +       timer_shutdown(&ptr->timer);
    |
    -       del_timer_sync(&ptr->timer);
    +       timer_shutdown_sync(&ptr->timer);
    )
      ... when strict
          when != ptr->timer
    (
            kfree_rcu(ptr, rfield);
    |
            kmem_cache_free(slab, ptr);
    |
            kfree(ptr);
    )
