Subject: [PATCH 001/160] clk: sunxi-ng: h6: Use sigma-delta modulation for
audio PLL
Audio devices needs exact clock rates in order to correctly reproduce
the sound. Until now, only integer factors were used to configure H6
audio PLL which resulted in inexact rates. Fix that by adding support
for fractional factors using sigma-delta modulation look-up table. It
contains values for two most commonly used audio base frequencies.

A NULL pointer would be passed to a call of the function kfree()

Remove this superfluous function call.
This issue was detected by using the Coccinelle software.

support
As of commit 362b334b17943d84 ("ARM: dts: r8a7791: Convert to new
CPG/MSSR bindings"), all upstream R-Car Gen2 device tree source files
use the unified "Renesas Clock Pulse Generator / Module Standby and
Software Reset" DT bindings.
Hence remove backward compatibility with old R-Car Gen2 device trees
describing a hierarchical representation of the various CPG and MSTP
clocks.

- Prefer ULL constant suffixes over casts to u64,

in SD .set_rate()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The .set_rate() callback for the SD clocks is always called with a valid
clock rate, returned by .round_rate(). Hence there is no need to
iterate through the divider table twice: once to repeat the work done by
.round_rate(), and a second time to find the corresponding divider
entry.
Just iterate once, looking for the divider that matches the passed clock
rate.

cpg_sd_clock_round_rate() really needs the best rate, not the best

the final division.

Subject: [PATCH 013/160] clk: sunxi-ng: h6: Allow GPU to change parent rate
GPU PLL was designed with dynamic frequency switching in mind so driver
can adjust rate based on the GPU load.
Allow GPU clock to change parent rate (GPU PLL is the only possible
parent of GPU clock).

Subject: [PATCH 017/160] clk: mvebu: armada-37xx-periph: add PCIe gated clock
The PCIe clock is a gated clock which has the same source as GbE0
(both IPs share a set of registers). This source clock is called
'gbe_core' in the driver.

Subject: [PATCH 018/160] clk: mvebu: armada-37xx-periph: change suspend/resume
time
Armada 3700 PCIe IP relies on the PCIe clock managed by this
driver. For reasons related to the PCI core's organization when
suspending/resuming, PCI host controller drivers must reconfigure
their registers at suspend_noirq()/resume_noirq() which happens after
suspend()/suspend_late() and before resume_early()/resume().
Device link support in the clock framework enforce that the clock
driver's resume() callback will be called before the PCIe
driver's. But, any resume_noirq() callback will be called before all
the registered resume() callbacks.
The solution to support PCIe resume operation is to change the
"priority" of this clock driver PM callbacks to "_noirq()".

Subject: [PATCH 022/160] clk: imx8mm: Move 1443X/1416X PLL clock structure to
common place
Many i.MX8M SoCs use same 1443X/1416X PLL, such as i.MX8MM,
i.MX8MN and later i.MX8M SoCs, moving these PLL definitions
to pll14xx driver can save a lot of duplicated code on each
platform.
Meanwhile, no need to define PLL clock structure for every
module which uses same type of PLL, e.g., audio/video/dram use
1443X PLL, arm/gpu/vpu/sys use 1416X PLL, define 2 PLL clock
structure for each group is enough.

Subject: [PATCH 029/160] clk: meson: axg-audio: prepare sm1 addition
Rearrange the macro definition of the clocks of the axg-audio
controller. Also, the sm1 variant will feature tiny modification
of different blocks in this controller. Because of that, we need
to fallback to the old way of defining parent for some of the
clocks, using signal name.

Subject: [PATCH 030/160] clk: meson: axg-audio: provide clk top signal name
The peripheral clock on the sm1 goes through some muxes
and dividers before reaching the audio gates. To model that,
without repeating our self too much, the "top" clock signal
is introduced and will serve as a the parent of the gates.
On the axg and g12a, the top clock is just a pass-through to
the audio peripheral clock provided by the main controller.

Subject: [PATCH 031/160] clk: meson: axg_audio: add sm1 support
Add sm1 support the axg audio clock controllers. This new version is
indeed derived from the previous generation, as always, adding a few
new clocks to the mix.
The number of gates now exceeds 32 and do not fit in a single register.
Unfortunately, designers chose to introduce the new gate register
immediately after the original one, at the beginning of the register
space, shifting all the master clock register offsets.
The sm1 also introduce a few mux and divider on the top clock path,
possibly to lower the peripheral clocks of the audio blocks if
necessary.

Subject: [PATCH 054/160] clk: imx8mm: Define gates for pll1/2 fixed dividers
On imx8mm there are 9 fixed-factor dividers for SYS_PLL1 and SYS_PLL2
each with their own gate. Only one of these gates (the one "dividing" by
one) is currently defined and it's incorrectly set as the parent of all
the fixed-factor dividers.
Add the other 8 gates to the clock tree between sys_pll1/2_bypass and
the fixed dividers.

Subject: [PATCH 055/160] clk: imx8mn: Define gates for pll1/2 fixed dividers
On imx8mn there are 9 fixed-factor dividers for SYS_PLL1 and SYS_PLL2
each with their own gate. Only one of these gates (the one "dividing" by
one) is currently defined and it's incorrectly set as the parent of all
the fixed-factor dividers.
Add the other 8 gates to the clock tree between sys_pll1/2_bypass and
the fixed dividers.

Subject: [PATCH 056/160] clk: imx: imx8mm: mark sys_pll1/2 as fixed clock
According Architecture definition guide, SYS_PLL1 is fixed at
800MHz, SYS_PLL2 is fixed at 1000MHz, so let's use imx_clk_fixed
to register the clocks and drop code that could change the rate.

Subject: [PATCH 065/160] clk: imx7ulp: do not export out IMX7ULP_CLK_MIPI_PLL
clock
The mipi pll clock comes from the MIPI PHY PLL output, so
it should not be a fixed clock.
MIPI PHY PLL is in the MIPI DSI space, and it is used as
the bit clock for transferring the pixel data out and its
output clock is configured according to the display mode.
So it should be used only for MIPI DSI and not be exported
out for other usages.

configuration during suspend/resume
Save and restore top PLL related configuration registers for big (APLL)
and LITTLE (KPLL) cores during suspend/resume cycle. So far, CPU clocks
were reset to default values after suspend/resume cycle and performance
after system resume was affected when performance governor has been selected.

Add CLK_SET_RATE_PARENT flag to all clocks on the path from VPLL to G3D,
so the G3D MALI driver can simply adjust the rate of its clock by doing
a single clk_set_rate() call, without the need to know the whole clock
topology in Exynos542x SoCs.

Subject: [PATCH 077/160] clk: ti: dra7xx: Drop idlest polling from IPU & DSP
clkctrl clocks
The IPU and DSP remote processor cores and their corresponding MMUs on
DRA7 SoCs have hardreset lines associated with them and are controlled
by a PRCM reset line each. Any clkctrl enable/disable operations cannot
be checked for module enabled/disabled status independent of the reset
operation, and this causes some unwanted timeouts in the kernel and
unbalanced states for these clocks. These details should be handled by
the driver integration code itself.
Add the CLKF_NO_IDLEST flag to both the IPU and DSP clkctrl clocks so
that these module status checks are skipped.

Subject: [PATCH 085/160] clk: ti: divider: cleanup ti_clk_parse_divider_data
API
Cleanup the ti_clk_parse_divider_data to pass the divider data struct
directly instead of individual values of it. This makes it easier
to modify the implementation later on.

Subject: [PATCH 086/160] clk: ti: divider: convert to use min,max,mask instead
of width
The existing width field used to check divider validity does not provide
enough protection against bad values. For example, if max divider value
is 4, the smallest all-1 bitmask that can hold this value is 7, which
allows values higher than 4 to be used. This typically causes
unpredictable results with hardware. So far this issue hasn't been
noticed as most of the dividers actually have maximum values which fit
the whole bitfield, but there are certain clocks for which this is a
problem, like dpll4_m4 divider on omap3 devices.
Thus, convert the whole validity logic to use min,max and mask values
for determining if a specific divider is valid or not. This prevents
the odd cases where bad value would otherwise be written to a divider
config register.

Subject: [PATCH 087/160] ARM: dts: omap3: fix DPLL4 M4 divider max value
The maximum divider value for DPLL4 M4 divider appears wrong. For most
OMAP3 family SoCs this is 16, but it is defined as 32, which is maybe
only valid for omap36xx. To avoid any overflows in trying to write this
register, set the max to 16 for all omap3 family, except omap36xx. For
omap36xx the maximum is set to 31, as it appears value 32 is not working
properly.

Subject: [PATCH 091/160] dt-bindings: clock: Add r8a77961 CPG Core Clock
Definitions
Add all Clock Pulse Generator Core Clock Outputs for the Renesas R-Car
M3-W+ (R8A77961) SoC, as listed in Table 8.2b ("List of Clocks [R-Car
M3-W/R-Car M3-W+]") of the R-Car Series, 3rd Generation Hardware User's
Manual (Rev. 2.00, Jul. 31, 2019). A gap is added for CSIREF, to
preserve compatibility with the definitions for R-Car M3-W (R8A77960).
Note that internal CPG clocks (S0, S1, S2, S3, SDSRC, SSPSRC, and POST2)
are not included, as they are used as internal clock sources only, and
never referenced from DT.

Subject: [PATCH 092/160] dt-bindings: clock: renesas: Remove R-Car Gen2 legacy
DT bindings
As of commit 362b334b17943d84 ("ARM: dts: r8a7791: Convert to new
CPG/MSSR bindings"), all upstream R-Car Gen2 device tree source files
use the unified "Renesas Clock Pulse Generator / Module Standby and
Software Reset" DT bindings.
Hence remove the old R-Car Gen2 DT bindings describing a hierarchical
representation of the various CPG and MSTP clocks.

-* Renesas R-Car Gen2 Clock Pulse Generator (CPG)
-
-The CPG generates core clocks for the R-Car Gen2 SoCs. It includes three PLLs
-and several fixed ratio dividers.
-The CPG also provides a Clock Domain for SoC devices, in combination with the
-CPG Module Stop (MSTP) Clocks.
-
-Required Properties:
-
- - compatible: Must be one of
- - "renesas,r8a7790-cpg-clocks" for the r8a7790 CPG
- - "renesas,r8a7791-cpg-clocks" for the r8a7791 CPG
- - "renesas,r8a7792-cpg-clocks" for the r8a7792 CPG
- - "renesas,r8a7793-cpg-clocks" for the r8a7793 CPG
- - "renesas,r8a7794-cpg-clocks" for the r8a7794 CPG
- and "renesas,rcar-gen2-cpg-clocks" as a fallback.
-
- - reg: Base address and length of the memory resource used by the CPG
-
- - clocks: References to the parent clocks: first to the EXTAL clock, second
- to the USB_EXTAL clock
- - #clock-cells: Must be 1
- - clock-output-names: The names of the clocks. Supported clocks are "main",
- "pll0", "pll1", "pll3", "lb", "qspi", "sdh", "sd0", "sd1", "z", "rcan", and
- "adsp"
- - #power-domain-cells: Must be 0
-
-SoC devices that are part of the CPG/MSTP Clock Domain and can be power-managed
-through an MSTP clock should refer to the CPG device node in their
-"power-domains" property, as documented by the generic PM domain bindings in
-Documentation/devicetree/bindings/power/power_domain.txt.
-

Subject: [PATCH 097/160] clk: renesas: r8a7796: Add R8A77961 CPG/MSSR support
Add support for the R-Car M3-W+ (R8A77961) SoC to the Renesas Clock
Pulse Generator / Module Standby and Software Reset driver.
R-Car M3-W+ is very similar to R-Car M3-W (R8A77960), which allows for
both SoCs to share a driver. R-Car M3-W+ lacks a few modules, so their
clocks must be nullified.
Based on a patch in the BSP by Takeshi Kihara
<takeshi.kihara.df@renesas.com>.

Subject: [PATCH 098/160] clk: imx: imx8mq: fix sys3_pll_out_sels
It is not correct that sys3_pll_out use sys2_pll1_ref_sel as parent.
According to the current imx_clk_sccg_pll design, it uses both
bypass1/2, however set bypass2 as 1 is not correct, because it will
make sys[x]_pll_out use wrong parent and might access wrong registers.
So correct bypass2 to 0 and fix sys3_pll_out_sels.
Fixes: e9dda4af685f ("clk: imx: Refactor entire sccg pll clk")

Subject: [PATCH 102/160] clk: rockchip: move px30 critical clocks to correct
clock controller
The clocks in the px30 critical clock section are from the regular cru not
the pmucru, so move them to the correct place.

Subject: [PATCH 103/160] clk: rockchip: add video-related niu clocks as
critical on px30
Video-In and -Out interconnect clocks need to stay on all the
time for the peripheral to work and we do not model the actual
interconnect at this point. So mark them as critical for now.

Subject: [PATCH 107/160] clk: qcom: rcg: update the DFS macro for RCG
Update the init data name for each of the dynamic frequency switch
controlled clock associated with the RCG clock name, so that it can be
generated as per the hardware plan. Thus update the macro accordingly.

Subject: [PATCH 111/160] clk: qcom: Add Global Clock controller (GCC) driver
for SC7180
Add support for the global clock controller found on SC7180
based devices. This should allow most non-multimedia device
drivers to probe and control their clocks.

Subject: [PATCH 116/160] clk: qcom: smd: Add missing pnoc clock
When MSM8998 support was added, and analysis was done to determine what
clocks would be consumed. That analysis had a flaw, which caused the
pnoc to be skipped. The pnoc clock needs to be on to access the uart
for the console. The clock is on from boot, but has no consumer votes
in the RPM. When we attempt to boot the modem, it causes the RPM to
turn off pnoc, which kills our access to the console and causes CPU hangs.
We need pnoc to be defined, so that clk_smd_rpm_handoff() will put in
an implicit vote for linux and prevent issues when booting modem.
Hopefully pnoc can be consumed by the interconnect framework in future
so that Linux can rely on explicit votes.

Subject: [PATCH 117/160] clk: qcom: Allow constant ratio freq tables for rcg
Some RCGs (the gfx_3d_src_clk in msm8998 for example) are basically just
some constant ratio from the input across the entire frequency range. It
would be great if we could specify the frequency table as a single entry
constant ratio instead of a long list, ie:
{ .src = P_GPUPLL0_OUT_EVEN, .pre_div = 3 },
{ }
So, lets support that.
We need to fix a corner case in qcom_find_freq() where if the freq table
is non-null, but has no frequencies, we end up returning an "entry" before
the table array, which is bad. Then, we need ignore the freq from the
table, and instead base everything on the requested freq.

Subject: [PATCH 123/160] clk: clk-gpio: propagate rate change to parent
For an external clock source, which is gated via a GPIO, the
rate change should typically be propagated to the parent clock.
The situation where we are requiring this propagation, is when an
external clock is connected to override an internal clock (which typically
has a fixed rate). The external clock can have a different rate than the
internal one, and may also be variable, thus requiring the rate
propagation.
This rate change wasn't propagated until now, and it's unclear about cases
where this shouldn't be propagated. Thus, it's unclear whether this is
fixing a bug, or extending the current driver behavior. Also, it's unsure
about whether this may break any existing setups; in the case that it does,
a device-tree property may be added to disable this flag.

Subject: [PATCH 125/160] clk: tegra: Add Tegra20/30 EMC clock implementation
A proper External Memory Controller clock rounding and parent selection
functionality is required by the EMC drivers, it is not available using
the generic clock implementation because only the Memory Controller driver
is aware of what clock rates are actually available for a particular
device. EMC drivers will have to register a Tegra-specific CLK-API
callback which will perform rounding of a requested rate. EMC clock users
won't be able to request EMC clock by getting -EPROBE_DEFER until EMC
driver is probed and the callback is set up.
The functionality is somewhat similar to the clk-emc.c which serves
Tegra124+ SoCs. The later HW generations support more parent clock sources
and the HW configuration / integration with the EMC drivers differs a tad
from the older gens, hence it's not really worth to try to squash
everything into a single source file.

Subject: [PATCH 126/160] clk: tegra: Remove last remains of
TEGRA210_CLK_SOR1_SRC
Later SoC generations implement this clock as SOR1_OUT. For consistency,
the Tegra210 implementation was adapted to match the same name in commit
4d1dc4018573 ("dt-bindings: clock: tegra: Add sor1_out clock").
Clean up the remaining pieces by adopting the new name for the internal
identifiers and remove the old alias. Note that since both SOR1_SRC and
SOR1_OUT were referring to the same device tree clock ID, this does not
break device tree ABI.

The SOR0 clock on Tegra210 is very different from the SOR0 clock found
on Tegra124. Move the Tegra124 implementation to the Tegra124 driver so
that a custom implementation can be provided on Tegra210 without
clashing with the existing clock.

Subject: [PATCH 131/160] clk: tegra: divider: Save and restore divider rate
This patch implements context restore for clock divider.
During system suspend, core power goes off and looses the settings
of the Tegra CAR controller registers.
So on resume, clock dividers are restored back for normal operation.

This patch implements save and restore of pllout context.
During system suspend, core power goes off and looses the settings
of the Tegra CAR controller registers.
So during suspend entry the state of pllout is saved and on resume
it is restored back to have pllout in same state as before suspend.
pllout rate is saved and restore in clock divider so it will be at
same rate as before suspend when pllout state is restored.

This patch implements restore_context support for clk-periph and
clk-sdmmc-mux clock operations to restore clock parent and rates
on system resume.
During system suspend, core power goes off and looses the context
of the Tegra clock controller registers.
So on system resume, clocks parent and rate are restored back to
the context before suspend based on cached data.

Subject: [PATCH 136/160] clk: tegra: clk-super: Fix to enable PLLP branches to
CPU
This patch has a fix to enable PLLP branches to CPU before changing
the CPU cluster clock source to PLLP for Gen5 Super clock and
disables PLLP branches to CPU when not in use.
During system suspend entry and exit, CPU source will be switched
to PLLP and this needs PLLP branches to be enabled to CPU prior to
the switch.
On system resume, warmboot code enables PLLP branches to CPU and
powers up the CPU with PLLP clock source.

This patch implements restore_context for clk_super_mux and clk_super.
During system supend, core power goes off the and context of Tegra
CAR registers is lost.
So on system resume, context of super clock registers are restored
to have them in same state as before suspend.

Subject: [PATCH 138/160] clk: tegra: clk-dfll: Add suspend and resume support
This patch implements DFLL suspend and resume operation.
During system suspend entry, CPU clock will switch CPU to safe
clock source of PLLP and disables DFLL clock output.
DFLL driver suspend confirms DFLL disable state and errors out on
being active.
DFLL is re-initialized during the DFLL driver resume as it goes
through complete reset during suspend entry.

Subject: [PATCH 141/160] clk: tegra: Add suspend and resume support on
Tegra210
All the CAR controller settings are lost on suspend when core power goes
off. This implement saving and restoring context for all PLLs and clocks
during system suspend and resume to have the clocks back to same state
for normal operation.
Clock driver suspend and resume are registered as syscore_ops as clocks
restore need to happen before the other drivers resume to have all their
clocks back to the same state as before suspend.

Subject: [PATCH 152/160] clk: mark clk_disable_unused() as __init
clk_disable_unused is only called once, as a late_initcall, so reclaim
a bit of memory by marking it (and the functions and data it is the
sole user of) as __init/__initdata. This moves ~1900 bytes from .text
to .init.text for a imx_v6_v7_defconfig.

There's no longer any need host a tree solely to serve changes for the
Ux500 clock driver, thus drop this from the corresponding section and use
the common clk tree instead.
Moreover, let's also add the generic linux-clk mailing list and rename the
section header.
