git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk updates from Stephen Boyd:
"This round of clk driver and framework updates is heavy on the driver
update side. The two main highlights in the core framework are the
addition of an bulk clk_get API that handles optional clks and an
extra debugfs file that tells the developer about the current parent
of a clk.
The driver updates are dominated by i.MX in the diffstat, but that is
mostly because that SoC has started converting to the clk_hw style of
clk registration. The next big update is in the Amlogic meson clk
driver that gained some support for audio, cpu, and temperature clks
while fixing some PLL issues. Finally, the biggest thing that stands
out is the conversion of a large part of the Allwinner sunxi-ng driver
to the new clk parent scheme that uses less strings and more pointer
comparisons to match clk parents and children up.
In general, it looks like we have a lot of little fixes and tweaks
here and there to clk data along with the normal addition of a handful
of new drivers and a couple new core framework features.
Core:
- Add a 'clk_parent' file in clk debugfs
- Add a clk_bulk_get_optional() API (with devm too)
New Drivers:
- Support gated clk controller on MIPS based BCM63XX SoCs
- Support SiLabs Si5341 and Si5340 chips
- Support for CPU clks on Raspberry Pi devices
- Audsys clock driver for MediaTek MT8516 SoCs
Updates:
- Convert a large portion of the Allwinner sunxi-ng driver to new clk parent scheme
- Small frequency support for SiLabs Si544 chips
- Slow clk support for AT91 SAM9X60 SoCs
- Remove dead code in various clk drivers (-Wunused)
- Support for Marvell 98DX1135 SoCs
- Get duty cycle of generic pwm clks
- Improvement in mmc phase calculation and cleanup of some rate defintions
- Switch i.MX6 and i.MX7 clock drivers to clk_hw based APIs
- Add GPIO, SNVS and GIC clocks for i.MX8 drivers
- Mark imx6sx/ul/ull/sll MMDC_P1_IPG and imx8mm DRAM_APB as critical clock
- Correct imx7ulp nic1_bus_clk and imx8mm audio_pll2_clk clock setting
- Add clks for new Exynos5422 Dynamic Memory Controller driver
- Clock definition for Exynos4412 Mali
- Add CMM (Color Management Module) clocks on Renesas R-Car H3, M3-N, E3, and D3
- Add TPU (Timer Pulse Unit / PWM) clocks on Renesas RZ/G2M
- Support for 32 bit clock IDs in TI's sci-clks for J721e SoCs
- TI clock probing done from DT by default instead of firmware
- Fix Amlogic Meson mpll fractional part and spread sprectrum issues
- Add Amlogic meson8 audio clocks
- Add Amlogic g12a temperature sensors clocks

Texas Instrument's System Control Interface (TI-SCI) Message Protocol
is used in Texas Instrument's System on Chip (SoC) such as those
in K3 family AM654 SoC to communicate between various compute
processors with a central system controller entity.
The system controller provides various services including the control
of other compute processors within the SoC. Extend the TI-SCI protocol
support to add various TI-SCI commands to invoke services associated
with power and reset control, and boot vector management of the
various compute processors from the Linux kernel.

the following:
Rings from Ring Accelerator
PSI-L thread management
UDMAP tchan, rchan and rflow configuration.

Future SoCs are going to have more than 255 device clocks in certain cases,
and thus the API must be extended to support this. The support is done in
backwards compatible extension, in which the new u32 clock identifier
fields are only used if the existing u8 size clock identifier is set as
255. In all the other cases, the existing u8 clock identifier is used. As
the size of the messages sent / received is not verified for existing
devices / old firmware, increasing the size of the messages from the end
is also fine. Due to this reason, depending on ABI version isn't necessary
either.

TISCI provides support for getting the resources(IRQ, RING etc..)
assigned to a specific device. These resources can be handled by
the client and in turn sends TISCI cmd to configure the resources.
It is very important that client should keep track on usage of these
resources.
Add support for TISCI commands to get resource ranges.

Since system controller now has control over SoC power management, it
needs to be explicitly requested to reboot the SoC. Add support for
it.
In some systems however, SoC needs to toggle a GPIO or send event to an
external entity (like a PMIC) for a system reboot to take place. To
facilitate that, we allow for a DT property to determine if the reboot
handler will be registered and further, the service is also made
available to other drivers (such as PMIC driver) to sequence the
additional operation and trigger the SoC reboot as the last step.

Texas Instrument's System Control Interface (TI-SCI) Message Protocol
is used in Texas Instrument's System on Chip (SoC) such as those
in keystone family K2G SoC to communicate between various compute
processors with a central system controller entity.
TI-SCI message protocol provides support for management of various
hardware entities within the SoC. Add support driver to allow
communication with system controller entity within the SoC using the
mailbox client.
In general, we expect to function at a device level of abstraction,
however, for proper operation of hardware blocks, many clocks directly
supplying the hardware block needs to be queried or configured.
Introduce support for the set of SCI message protocol support that
provide us with this capability.
