Pull one more T-HEAD clk driver update from Drew Fustini:

Yao Zi has fixed an issue where the c910 mux clk could end up as an
orphan in CCF when the bootloader reparents it to the c910-i0 mux clk.
The solution is to refactor the handling of mux clocks by embedding a
clk_mux structure directly in ccu_mux. This allows the mux clocks to be
registered with devm_clk_hw_register() without allocating any new clk_hw
pointer which solves the orphan issue.

This change has been tested in linux-next. The LPi4a still boots okay
without clk_ignore_unused and peripherals like serial, emmc and ethernet
are functional. The file /sys/kernel/debug/clk/c910/clk_possible_parents
now correctly outputs: "c910-i0 cpu-pll1"

clk: thead: th1520-ap: Describe mux clocks with clk_mux

Mux clocks are now described with a customized ccu_mux structure
consisting of ccu_internal and ccu_common substructures, and registered
later with devm_clk_hw_register_mux_parent_data_table(). As this helper
always allocates a new clk_hw structure, it's extremely hard to use mux
clocks as parents statically by clk_hw pointers, since CCF has no
knowledge about the clk_hw structure embedded in ccu_mux.

This scheme already causes issues for clock c910, which takes a mux
clock, c910-i0, as a possible parent. With mainline U-Boot that
reparents c910 to c910-i0 at boottime, c910 is considered as an orphan
by CCF.

This patch refactors handling of mux clocks, embeds a clk_mux structure
in ccu_mux directly. Instead of calling devm_clk_hw_register_mux_*(),
we could register mux clocks on our own without allocating any new
clk_hw pointer, fixing c910 clock's issue.

Enabling runtime PM without explicitly resuming the device caused
the power domain cut off after clk_register() is called. As a result,
a crash happens when the clock hardware provider is added and attempts
to access the BLK_CTL register.

Fix this by using devm_pm_runtime_enable() instead of pm_runtime_enable()
and getting rid of the pm_runtime_disable() in the cleanup path.

>From the build perspective, the videocc-sm8550 driver doesn't depend on
having one of the GCC drivers enabled. It builds just fine without the GCC
driver. In practice, it doesn't make much sense to have it enabled without
the GCC driver, but currently this extra dependency is inconsistent with
most of the other VIDEOCC entries in Kconfig. This can easily cause
confusion when you see the VIDEOCC options for some of the SoCs but not for
all of them.

Let's just drop the depends line to allow building the videocc driver
independent of the GCC selection. Compile testing with randconfig will also
benefit from keeping the dependencies minimal.

I manually fixed up one minor formatting issue that occurred after
applying the semantic patch:

        req->rate = ccu_nm_find_best(&nm->common, req->best_parent_rate,
                                     req->rate,
                                     &_nm);

I manually changed it to:

        req->rate = ccu_nm_find_best(&nm->common, req->best_parent_rate,
                                     req->rate, &_nm);

3 weeks agoclk: sunxi-ng: v3s: Assign the de and tcon clocks to the video pll
Paul Kocialkowski [Fri, 4 Jul 2025 15:40:08 +0000 (17:40 +0200)] 
clk: sunxi-ng: v3s: Assign the de and tcon clocks to the video pll

It appears (based on experimentation) that both the de and tcon clocks
need to have the same parent for the two units to work together.

Assign them both to the video pll by manually clearing the parent
selection bits (effectively setting index 0) and marking the clocks
with the CLK_SET_RATE_NO_REPARENT flag, which ensures that they will
never use a different parent.

The video pll is also a possible parent for the camera subsystem,
but it can use the dedicated isp pll if needed so there should be
no negative side-effect due to this change.

Note that ccu_mux_helper_set_parent cannot be used at this stage as
it requires the clock driver to be initialized and this configuration
is best done before the clock driver is available to consumers.

restricts flexibility for other clocks using the same parent.

In addition the source selection (parent) field is marked as using
2 bits, when it the documentation reports that it uses 3.
