clk: qcom: gcc: Add missing UFS clocks for SM8150

2020-07-22T07:33:07+00:00

commit 37c72e4cae37f0dace1abb3711ede7fbc6d0862a upstream.

Add the missing ufs card and ufs phy clocks for SM8150. They were missed
in earlier addition of clock driver.

clk: AST2600: Add mux for EMMC clock

2020-07-22T07:33:03+00:00

[ Upstream commit c2407ab3bd55064d459bc822efd1c134e852798c ]

The EMMC clock can be derived from either the HPLL or the MPLL. Register
a clock mux so that the rate is calculated correctly based upon the
parent.

clk: mvebu: ARMADA_AP_CPU_CLK needs to select ARMADA_AP_CP_HELPER

2020-07-22T07:33:03+00:00

[ Upstream commit 8e3709d7e3a67e2d3f42bd1fc2052353a5678944 ]

When building arm32 allmodconfig:

ld.lld: error: undefined symbol: ap_cp_unique_name
>>> referenced by ap-cpu-clk.c
>>>               clk/mvebu/ap-cpu-clk.o:(ap_cpu_clock_probe) in archive drivers/built-in.a

ap_cp_unique_name is only compiled into the kernel image when
CONFIG_ARMADA_AP_CP_HELPER is selected (as it is not user selectable).
However, CONFIG_ARMADA_AP_CPU_CLK does not select it.

This has been a problem since the driver was added to the kernel but it
was not built before commit c318ea261749 ("cpufreq: ap806: fix cpufreq
driver needs ap cpu clk") so it was never noticed.

clk: sifive: allocate sufficient memory for struct __prci_data

2020-06-30T19:37:01+00:00

[ Upstream commit d0a5fdf4cc83dabcdea668f971b8a2e916437711 ]

The (struct __prci_data).hw_clks.hws is an array with dynamic elements.
Using struct_size(pd, hw_clks.hws, ARRAY_SIZE(__prci_init_clocks))
instead of sizeof(*pd) to get the correct memory size of
struct __prci_data for sifive/fu540-prci. After applying this
modifications, the kernel runs smoothly with CONFIG_SLAB_FREELIST_RANDOM
enabled on the HiFive unleashed board.

clk: ast2600: Fix AHB clock divider for A1

[ Upstream commit 2d491066ccd4286538450c227fc5094ceb04b494 ]

The latest specs for the AST2600 A1 chip include some different bit
definitions for calculating the AHB clock divider. Implement these in
order to get the correct AHB clock value in Linux.

clk: sprd: return correct type of value for _sprd_pll_recalc_rate

2020-06-24T15:50:35+00:00

[ Upstream commit c2f30986d418f26abefc2eec90ebf06716c970d2 ]

The function _sprd_pll_recalc_rate() defines return value to unsigned
long, but it would return a negative value when malloc fail, changing
to return its parent_rate makes more sense, since if the callback
.recalc_rate() is not set, the framework returns the parent_rate as
well.

clk: bcm2835: Fix return type of bcm2835_register_gate

2020-06-24T15:50:34+00:00

[ Upstream commit f376c43bec4f8ee8d1ba5c5c4cfbd6e84fb279cb ]

bcm2835_register_gate is used as a callback for the clk_register member
of bcm2835_clk_desc, which expects a struct clk_hw * return type but
bcm2835_register_gate returns a struct clk *.

This discrepancy is hidden by the fact that bcm2835_register_gate is
cast to the typedef bcm2835_clk_register by the _REGISTER macro. This
turns out to be a control flow integrity violation, which is how this
was noticed.

Change the return type of bcm2835_register_gate to be struct clk_hw *
and use clk_hw_register_gate to do so. This should be a non-functional
change as clk_register_gate calls clk_hw_register_gate anyways but this
is needed to avoid issues with further changes.

clk: samsung: exynos5433: Add IGNORE_UNUSED flag to sclk_i2s1

2020-06-24T15:50:30+00:00

[ Upstream commit 25bdae0f1c6609ceaf55fe6700654f0be2253d8e ]

Mark the SCLK clock for Exynos5433 I2S1 device with IGNORE_UNUSED flag to
match its behaviour with SCLK clock for AUD_I2S (I2S0) device until
a proper fix for Exynos I2S driver is ready.

This fixes the following synchronous abort issue revealed by the probe

The parent_names is never released for a component clock definition,
causing some memory leak. Fix by releasing it once it is no longer
needed.
