Subject: [PATCH 01/51] clk: renesas: rcar-gen3: Pass name/offset to
cpg_sd_clk_register()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Explicitly pass the clock's name and register offset to
cpg_sd_clk_register(), so the latter doesn't have to extract them from
the cpg_core_clk object.
This keeps all cpg_core_clk parsing and unmarshalling contained in a
single function (rcar_gen3_cpg_clk_register()).

Since i.MX7ULP B0 chip, the SNVS module is moved into M4
domain and its clock is also moved into PCC0 which is
contorlled by M4, Linux kernel should NOT add it into
clock tree.

Subject: [PATCH 08/51] clk: renesas: rcar-gen3: Parameterise Z and Z2 clock
offset
Parameterise the offset of control bits within the FRQCRC register
for Z and Z2 clocks.
This is in preparation for supporting the Z2 clock on the R-Car E3
(r8a77990) SoC which uses a different offset for control bits to
other, already, supported SoCs.
As suggested by Geert Uytterhoeven.

Subject: [PATCH 09/51] clk: renesas: rcar-gen3: Remove CLK_TYPE_GEN3_Z2
After recent reworking of Z and Z2 clk handling
CLK_TYPE_GEN3_Z and CLK_TYPE_GEN3_Z2 have come to have precisely
the same meaning. Remove this redundancy by eliminating the latter.
This is not expected to have any run-time effect.

Provide DIV64_U64_ROUND_CLOSEST helper which performs division rounded to
the closest integer using an unsigned 64bit dividend and divisor.
This will be used in a follow-up patch to allow calculation of clock
divisors with high frequency parents in the R-Car Gen3 CPG MSSR driver
where overflow occurs if either the dividend or divisor is 32bit.

Subject: [PATCH 11/51] clk: renesas: rcar-gen3: Support Z and Z2 clocks with
high frequency parents
Support Z and Z2 clocks with parent frequencies greater than UINT32_MAX Hz
(~4.29GHz).
The DIV_ROUND_CLOSEST_ULL() macro accepts a 64bit dividend and 32bit
divisor. This leads to truncation of the divisor, which is the Z or Z2
parent clock frequency in HZ, on platforms where frequency of that clock is
greater than UINT32_MAX Hz.
To resolve this problem the DIV64_U64_ROUND_CLOSEST() macro, which takes
on an unsigned 64bit dividend and divisor, is used.
An earlier version of this patch made use of the existing
DIV_ROUND_CLOSEST() macro, which accepts the prevailing type of the
dividend and divisor. However, this does not compile on 32bit systems, such
as i386 and mips, when called with the types used at this call site, an
unsigned long long dividend and unsigned long divisor.
This work is in preparation for supporting the Z2 clock on the
R-Car Gen3 E3 (r8a77990) SoC which has a 4.8GHz parent clock.

Subject: [PATCH 16/51] clk: renesas: rcar-gen3: Correct parent clock of
SYS-DMAC
The clock sources of the AXI BUS clock (266.66 MHz) used for SYS-DMAC
DMA transfers are:
Channel R-Car H3 R-Car M3-W R-Car M3-N
-------------------------------------------------
SYS-DMAC0 S0D3 S0D3 S0D3
SYS-DMAC1 S3D1 S3D1 S3D1
SYS-DMAC2 S3D1 S3D1 S3D1
As a result, change the parent clocks of the SYS-DMAC{1,2} module clocks
on R-Car H3, R-Car M3-W, and R-Car M3-N to S3D1.
NOTE: This information will be reflected in a future revision of the
R-Car Gen3 Hardware Manual.

Subject: [PATCH 17/51] clk: renesas: rcar-gen3: Correct parent clock of
Audio-DMAC
The clock sources of the AXI-bus clock (266.66 MHz) used for Audio-DMAC
DMA transfers are:
Channel R-Car H3 R-Car M3-W R-Car M3-N R-Car E3
---------------------------------------------------------------
Audio-DMAC0 S1D2 S1D2 S1D2 S1D2
Audio-DMAC1 S1D2 S1D2 S1D2 -
As a result, change the parent clocks of the Audio-DMAC{0,1} module
clocks on R-Car H3, R-Car M3-W, and R-Car M3-N to S1D2, and change the
parent clock of the Audio-DMAC0 module on R-Car E3 to S1D2.
NOTE: This information will be reflected in a future revision of the
R-Car Gen3 Hardware Manual.

Subject: [PATCH 18/51] clk: renesas: rcar-gen3: Rename DRIF clocks
According to the R-Car Gen3 Hardware Manual Errata for Rev. 1.50 of Feb
12, 2019, the DRIF clocks have been renamed as follows:
DRIF0 to DRIF00
DRIF1 to DRIF01
DRIF2 to DRIF10
DRIF3 to DRIF11
DRIF4 to DRIF20
DRIF5 to DRIF21
DRIF6 to DRIF30
DRIF7 to DRIF31
Therefore, this patch renames the DRIF clocks from DRIFn to DRIFmm.

Subject: [PATCH 19/51] clk: renesas: r8a77980: Fix RPC-IF module clock's
parent
Testing has shown that the RPC-IF module clock's parent is the RPCD2
clock, not the RPC one -- the RPC-IF register reads stall otherwise...

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
i.MX50 does not have a periph_apm clock. Instead, the main bus clock
(a.k.a. periph_clk) comes directly from a MUX between pll1_sw, pll2_sw,
pll3_sw, and lp_apm.

Subject: [PATCH 22/51] clk: renesas: rcar-gen3: Fix cpg_sd_clock_round_rate()
return value
cpg_sd_clock_round_rate() may return an unsupported clock rate for the
requested clock rate. Therefore, when cpg_sd_clock_set_rate() sets the
clock rate acquired by cpg_sd_clock_round_rate(), an error may occur.
This is not conform the clk API design.
This patch fixes that by making sure cpg_sd_clock_calc_div() considers
only the division values defined in cpg_sd_div_table[].
With this fix, the cpg_sd_clock_round_rate() always return a support
clock rate.

PLLs with tuner_en bit, such as APLL1, need to disable
tuner_en before apply new frequency settings, or the new frequency

The tuner_en bit will be disabled during changing PLL rate
and be restored after new settings applied.

Subject: [PATCH 25/51] clk: mediatek: Add new clkmux register API
On both MT8183 & MT6765, there add "set/clr" register for
each clkmux setting, and one update register to trigger value change.
It is designed to prevent read-modify-write racing issue.
The sw design need to add a new API to handle this hw change with
a new mtk_clk_mux/mtk_mux struct in new file "clk-mux.c", "clk-mux.h".

Subject: [PATCH 26/51] clk: mediatek: Add configurable pcwibits and fmin to
mtk_pll_data
1. pcwibits: The integer bits of pcw for PLLs is extend to 8 bits,
add a variable to indicate this change and
backward-compatible.
2. fmin: The PLL frequency lower-bound is vary from 1GHz to
1.5GHz, add a variable to indicate platform-dependent.

Subject: [PATCH 29/51] clk: mediatek: Add configurable pcw_chg_reg to
mtk_pll_data
In previous MediaTek PLL design, it assumes the pcw change control
is always on the CON1 register.
However, the pcw change bit on MT8183 was moved onto CON0 because
the the PCW length of audio PLLs are extended to 32-bit.
Add configurable pcw_chg_reg to set the pcw change control register
address or using the default control register CON1 if without
setting in pll data.

Subject: [PATCH 31/51] clk: mediatek: Allow changing PLL rate when it is off
Some modules may need to change its clock rate before turn on it.
So changing PLL's rate when it is off should be allowed.
This patch removes PLL enabled check before set rate, so that
PLLs can set new frequency even if they are off.
On MT8173 for example, ARMPLL's enable bit can be controlled by
other HW. That means ARMPLL may be turned on even if we (CPU / SW)
set ARMPLL's enable bit as 0. In this case, SW may want and can
still change ARMPLL's rate by changing its pcw and postdiv settings.
But without this patch, new pcw setting will not be applied because
its enable bit is 0.

Subject: [PATCH 45/51] clock: milbeaut: Add Milbeaut M10V clock controller
The M10V of the Milbeaut SoCs has an on-chip controller that derive
mostly clocks from a single external clock, using PLLs, dividers,
multiplexers and gates. Since the PLLs have already been started and
will not stop / restart, they are fixed factor. The gates will be added
in later patch (all of the gates are off state now).

Subject: [PATCH 46/51] clk: imx: correct i.MX7D AV PLL num/denom offset
According reference manual, i.MX7D's audio/video PLL's
num/denom register offset are 0x20/0x30, they are different
from i.MX6's audio/video PLL, correct it by introducing new
offset variables for audio/video PLL and using runtime
assignment based on PLL type.

Subject: [PATCH 48/51] clk: imx: pllv4: add fractional-N pll support
The pllv4 supports fractional-N function, the formula is:
PLL output freq = input * (mult + num/denom),

clock round rate, calculate rate and set rate, with this
patch, the clock rate of APLL in clock tree is more accurate
than before:

This patch is part of the ongoing efforts to enable

Subject: [PATCH 51/51] clk: imx: correct pfdv2 gate_bit/vld_bit operations
The operations of pfdv2 gate_bit/valid_bit are incorrect,
they are defined as u8 for bit offset, but gate_bit is
actually assigned as mask which could be 32 bit long and
it causes overflow, and vld_bit is assigned as bit offset
based on incorrect gate_bit value, it causes incorrect
pfd clock gate status in clock tree, this patch fixes the
issue by assigning them as correct bit offset.
