clk: samsung: update PLL locktime for PLL142XX used on FSD platform

2025-03-22T19:50:47+00:00

commit 53517a70873c7a91675f7244768aad5006cc45de upstream.

Currently PLL142XX locktime is 270. As per spec, it should be 150. Hence
update PLL142XX controller locktime to 150.

clk: mediatek: mt2701-mm: add missing dummy clk

2025-02-17T08:40:20+00:00

commit 67aea188f23a5dde51c31a720ccf66aed0ce4187 upstream.

Add dummy clk which was missed during the conversion to
mtk_clk_pdev_probe() and is required for the existing DT bindings to
keep working.

clk: mediatek: mt2701-aud: fix conversion to mtk_clk_simple_probe

2025-02-17T08:40:19+00:00

commit 5fba40be5fbad563914e3ce9d5129a6baaea1ff5 upstream.

Some of the audio subsystem clocks defined in clk-mt2701.h aren't
actually used by the driver. This broke conversion to
mtk_clk_simple_probe which expects that the highest possible clk id is
defined by the ARRAY_SIZE.

Add additional dummy clocks to fill the gaps and remain compatible with
the existing DT bindings.

clk: mediatek: mt2701-vdec: fix conversion to mtk_clk_simple_probe

2025-02-17T08:40:19+00:00

commit 7c8746126a4e256fcf1af9174ee7d92cc3f3bc31 upstream.

Commit 973d1607d936 ("clk: mediatek: mt2701: use mtk_clk_simple_probe to
simplify driver") broke DT bindings as the highest index was reduced by
1 because the id count starts from 1 and not from 0.

Fix this, like for other drivers which had the same issue, by adding a
dummy clk at index 0.

commit 89aa5925d201b90a48416784831916ca203658f9 upstream.

aggr_state and unit fields are u32. The result of their
multiplication may not fit in this type.

Add explicit casting to prevent overflow.

clk: qcom: dispcc-sm6350: Add missing parent_map for a clock

commit d4cdb196f182d2fbe336c968228be00d8c3fed05 upstream.

If a clk_rcg2 has a parent, it should also have parent_map defined,
otherwise we'll get a NULL pointer dereference when calling clk_set_rate
like the following:

Add the parent_map property for the clock where it's missing and also
un-inline the parent_data as well to keep the matching parent_map and
parent_data together.
