6f42f5e73b soc: mediatek: mtk-svs: add missing MODULE_DEVICE_TABLE 
This patch adds missing MODULE_DEVICE_TABLE definition
which generates correct modalias for automatic loading
of this driver when it is built as an external module.

916120df5a soc: mediatek: mtk-devapc: Switch to devm_clk_get_enabled() 
This driver does exactly devm_clk_get() and clk_prepare_enable() right
after, which is exactly what devm_clk_get_enabled() does: clean that
up by switching to the latter.

This commit brings no functional changes.

8af1f6b5bc soc: mediatek: add cmdq support of mtk-mmsys config API for mt8195 vdosys1 
Add cmdq support for mtk-mmsys config API.
The mmsys config register settings need to take effect with the other
HW settings(like OVL_ADAPTOR...) at the same vblanking time.

If we use CPU to write the mmsys reg, we can't guarantee all the
settings can be written in the same vblanking time.
Cmdq is used for this purpose. We prepare all the related HW settings
in one cmdq packet. The first command in the packet is "wait stream done",
and then following with all the HW settings. After the cmdq packet is
flush to GCE HW. The GCE waits for the "stream done event" to coming
and then starts flushing all the HW settings. This can guarantee all
the settings flush in the same vblanking.

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);
    )

    $ spatch timer.cocci . > /tmp/t.patch
    $ patch -p1 < /tmp/t.patch
