8bcb1b4898 firmware: scmi: prepare scmi uclass API to multi-channel
Changes SCMI driver API function devm_scmi_process_msg() to add
an SCMI channel reference argument for when SCMI agent supports
SCMI protocol specific channels. First argument of devm_scmi_process_msg()
is also change to point to the caller SCMI protocol device rather
than its parent device (the SCMI agent device).

The argument is a pointer to opaque struct scmi_channel known from
the SCMI transport drivers. It is currently unused and caller a pass
NULL value. A later change will enable such support once SCMI protocol
drivers have means to get the channel reference during initialization.

Upstream commit 7a2c3be95a ("clk: imx8mp: Fill in DWC3 USB, USB PHY,
HSIOMIX clock") added usb_core_ref for USB Controller but never set it
to be used as a clock source, using rather "osc_32k" instead.

This produces following boot log message:
"clk_register: failed to get osc_32k device (parent of usb_root_clk)"

Fix the USB controller clock source by using usb_core_ref instead of
osc_32k.

d6cb09d89d clk: sunxi: add and use dummy gate clocks
Some devices enumerate various clocks in their DT, and many drivers
just blanketly try to enable all of them. This creates problems
since we only model a few gate clocks, and the clock driver outputs
a warning when a clock is not described:
=========
sunxi_set_gate: (CLK#3) unhandled
=========

Some clocks don't have an enable bit, or are already enabled in a
different way, so we might want to just ignore them.

Add a CCU_CLK_F_DUMMY_GATE flag that indicates that case, and define
a GATE_DUMMY macro that can be used in the clock description array.
Define a few clocks, used by some pinctrl devices, that way to suppress
the runtime warnings.

444ab3569b clk: sunxi: add PIO bus gate clocks
The introduction of the DM pinctrl driver made its probe function enable
all clocks enumerated in the DT. This includes the "CLK_BUS_PIO" (and
variations) gate clock. Also CLK_PLL_PERIPH0 is used by the R_CCU device.
So far we didn't describe those clocks in our clock driver.
As we enable them already in the SPL, the devices happen to work, but
the clock driver still complains about not finding those clocks:
=========
sunxi_set_gate: (CLK#58) unhandled
=========

Add the one-liners that are needed to announce the gate bit for those
clocks, to silence that message on the console.

730a402450 rockchip: rk3066: add clock driver for rk3066 soc
Add the clock driver for the rk3066 platform.

Derived from the rk3288 and rk3188 driver it
supports only a bare minimum to bring up the system
to reduce the TPL size for:
  SDRAM clock configuration.
  The boot devices NAND, EMMC, SDMMC, SPI.
  A UART for the debug messages (fixed) at 115200n8.
  A SARADC for the recovery button.
  A TIMER for the delays (fixed).

There's support for two possible frequencies,
the safe 600MHz which will work with default pmic settings and
will be set to get away from the 24MHz default and
the maximum of 1.416Ghz, which boards can set if they
were able to get pmic support for it.

After the clock tree is set during the TPL probe
there's no parent update support.

In OF_REAL mode the drivers ns16550.c and dw-apb-timer.c
obtain the (fixed) clk_get_rate from the clock driver
instead of platdata.

The rk3066 cru node has a number of assigned-clocks properties
that call the .set_rate() function. Add them to the list so that
they return a 0 instead of -ENOENT.

fd426b3106 k210: use the board vendor name rather than the marketing name
"kendryte" is the marketing name for the K210 RISC-V SoC produced by
Canaan Inc. Rather than "kendryte,k210", use the usual "canaan,k210"
vendor,SoC compatibility string format in the device tree files and
use the SoC name for file names.
With these changes, the device tree files are more in sync with the
Linux kernel DTS and drivers, making uboot device tree usable by the
kernel.

6983710a31 scmi: change parameter dev in devm_scmi_process_msg
Changes devm_scmi_process_msg() first argument from target parent device
to current SCMI device and lookup the SCMI agent device among SCMI device
parents for find the SCMI agent operator needed for communication with
the firmware.

This change is needed in order to support CCF in clk_scmi driver unless
what CCF will fail to find the right udevice related to exposed SCMI
clocks.

This patch allows to simplify the caller sequence, using SCMI device
reference as parameter instead of knowing SCMI uclass topology. This
change also adds some protection in case devm_scmi_process_msg() API
function is called for an invalid device type.

It is safe to check if the uclass id on the device is UCLASS_CLK

not done on the device used in API: clkp->dev->parent

This patch corrects this behavior and tests if the parent device
is a clock device before to call the clock API, clk_enable or

The aforementioned patch causes massive breakage on all platforms which
have 'assigned-clock' DT property in their DT which references any clock
that are not supported by the platform clock driver. That can easily
happen either in SPL, or because the clock driver is reduced. Currently
it seems all iMX8M are affected and fail to boot altogether.

2f8a6db5d8 Finish conversion of CONFIG_SYS_CLK_FREQ to Kconfig
In order to finish moving this symbol to Kconfig for all platforms, we
need to do a few more things.  First, for all platforms that define this
to a function, introduce CONFIG_DYNAMIC_SYS_CLK_FREQ, similar to
CONFIG_DYNAMIC_DDR_CLK_FREQ and populate clock_legacy.h.  This entails
also switching all users from CONFIG_SYS_CLK_FREQ to get_board_sys_clk()
and updating a few preprocessor tests.

With that done, all platforms that define a value here can be converted
to Kconfig, and a fall-back of zero is sufficiently safe to use (and
what is used today in cases where code may or may not have this
available).  Make sure that code which calls this function includes
<clock_legacy.h> to get the prototype.

following warning seen when building sifive-prci.c:

  warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]

Change to use dev_read_addr_ptr().

Starting with commit 92f1e9a4b3 ("clk: Detect failure to set

no longer probe correctly, because setting the cpll and gpu clocks are
not supported with the clk_px30 U-Boot driver. This adds support for
setting the cpll clock to the clk_px30 driver. Another patch will
update the U-Boot specific device-tree to remove the GPU clock which is

The bulk of it is Samuel's DM_I2C rework, which removes the nasty I2C
deprecation warnings for most 32-bit boards. It also includes some
smaller refactorings that pave the way for more changes, mostly driven
by needing to support the Allwinner RISC-V SoC later on.

Board wise we gain support for the FriendlyARM NanoPi R1S H5 router
board and official Pinetab support.

Build-tested for all 160 sunxi boards, and boot tested on a A64, A20,
H3, H6, and H616 board. USB, SD card, eMMC, and Ethernet all work there
(where applicable).

165e8fe5db clk: ti: add am33xx/am43xx spread spectrum clock support
The patch enables spread spectrum clocking (SSC) for MPU and LCD PLLs.
As reported by the TI spruh73x/spruhl7x RM, SSC is only supported for
the DISP/LCD and MPU PLLs on am33xx/am43xx. SSC is not supported for
DDR, PER, and CORE PLLs.

Calculating the required values and setting the registers accordingly
was taken from the set_mpu_spreadspectrum routine contained in the
arch/arm/mach-omap2/am33xx/clock_am33xx.c file of the u-boot project.

In locked condition, DPLL output clock = CLKINP *[M/N]. In case of
SSC enabled, the reference manual explains that there is a restriction
of range of M values. Since the clk_ti_am3_dpll_round_rate() attempts
to select the minimum possible N, the value of M obtained is not
guaranteed to be within the range required. With the new "ti,min-div"
parameter it is possible to increase N and consequently M to satisfy the
constraint imposed by SSC.

The PLL functions take ulong arguments for rate, but still check if that

to use IS_ERR_VALUE (like is already done in k210_clk_set_rate). While

This adds support for setting clock rates, which was left out of the
initial CCF expunging. There are several tricky bits here, mostly related
to the PLLS:

* The PLL's bypass is broken. If the PLL is reconfigured, any child clocks
  will be stopped.
* PLL0 is the parent of ACLK which is the CPU and SRAM's clock. To prevent
  stopping the CPU while we configure PLL0's rate, ACLK is reparented
  to IN0 while PLL0 is disabled.
* PLL1 is the parent of the AISRAM clock. This clock cannot be reparented,
  so we instead just disallow changing PLL1's rate after relocation (when
  we are using the AISRAM).

609bd60b94 clk: k210: Rewrite to remove CCF
This is effectively a complete rewrite to remove all dependency on CCF.
The code is now smaller, and so is the binary. It also takes up less memory
at runtime (since we don't have to create 40 udevices). In general, I am
much happier with this driver as much of the complexity and late binding
has been removed.

The k210_*_params structs which were previously used to initialize CCF
clocks are now used as the complete configuration. Since we can write our
own division logic, we can now do away with several "half" clocks which
only existed to provide constant factors of two.

The clock IDs have been renumbered to remove unused clocks. This may not be
the last time they are renumbered, since we have diverged with Linux. There
are also still a few clocks left out which may need to be added back in.

In general, I have tried to leave out behavioral changes. However, there is
a small bugfix regarding ACLK. According to the technical reference manual,
its mux comes *after* its divider (which is present only for PLL0). This
would have required yet another intermediate clock to fix with CCF, but
with the new driver it is just 2 lines of code :)

6e33eba59f clk: Allow force setting clock defaults before relocation
Since 291da96b8e ("clk: Allow clock defaults to be set during re-reloc
state for SPL only") it has been impossible to set clock defaults before
relocation. This is annoying on boards without SPL, since there is no way
to set clock defaults before U-Boot proper. In particular, the aisram rate
must be changed before relocation on the K210, since U-Boot will hang if we
try and change the rate while we are using aisram.

To get around this, extend the stage parameter to allow force setting
defaults, even if they would be otherwise postponed for later. A device
tree property was decided against because of the concerns in the original
commit thread about the overhead of repeatedly parsing the device tree.

b1aef0384f clk: ti: add custom API for memory access
As pointed by [1] and [2], commit
d64b9cdcd4 ("fdt: translate address if #size-cells = <0>") is wrong:
- It makes every 'reg' DT property translatable. It changes the address
  translation so that for an I2C 'reg' address you'll get back as reg
  the I2C controller address + reg value.
- The quirk must be fixed with platform code.

The clk_ti_get_reg_addr() is the platform code able to make the correct
address translation for the AM33xx clocks registers. Its implementation
was inspired by the Linux Kernel code.

This function finds a device by its driver_info index. With
of-platdata-inst we do not use driver_info, but instead instantiate
udevice records at build-time.

However the semantics of using the function are the same in each case:
the caller provides an index and gets back a device.

So rename the function to device_get_by_ofplat_idx(), so that it can be
used for both situations. The caller does not really need to worry about
the details.
