Pull clk updates from Stephen Boyd:
"We've finally gotten rid of the struct clk_ops::round_rate() code
after months of effort from Brian Masney. Now the only option is to
use determine_rate(), which is good because that takes a struct
argument instead of just a couple unsigned longs, allowing us to
easily modify the way we determine and set rates in the clk tree.
Beyond that core framework change we've got the typical pile of new
SoC clk driver additions, fixes for clk data and/or adding missing
clks because the consumer driver using those clks wasn't ready, etc.
The usual suspects are all here: Qualcomm, Samsung, Mediatek, and
Rockchip along with some newcomers making RISC-V SoCs like ESWIN's
eic700 and Tenstorrent's Atlantis. The clk driver side of this looks
pretty normal.
Core:
- Remove the round_rate() clk op (yay!)
New Drivers:
- ESWIN eic700 SoC clk support
- Econet EN751221 SoC clock/reset support
- Global TCSR, RPMh, and display clock controller support for the
Qualcomm Eliza platform
- TCSR, the multiple global, and the RPMh clock controller support
for the Qualcomm Nord platform
- GPU clock controller support for Qualcomm SM8750
- Video and GPU clock controller support for Qualcomm Glymur
- Global clock controller support for Qualcomm IPQ5210
- Axis ARTPEC-9: Add new PLL clocks and new drivers for eight clock
controllers on the SoC
- ExynosAutov920: Add G3D (GPU) clock controller
- Clock driver for the Rockchip RV1103B SoC
- Initial support for the Renesas RZ/G3L (R9A08G046) SoC
- Clock and reset controllers (e.g. PRCM) in the Tenstorrent Atlantis SoC"

The "Other Logic Block" found in the EyeQ6Lplus from Mobileye provides
various functions for the controllers present in the SoC.
The OLB produces 22 clocks derived from its input, which is connected
to the main oscillator of the SoC.
It provides reset signals via two reset domains.
It also controls 32 pins to be either a GPIO or an alternate function.

Support for the RV1103B SoC and the Onion Omega4 board using it.
While the RV1103B only got a B-extension to its name, the SoC internals
were reworked heavily. So likely it's mainly pin compatible to the
non-B variant.
The dt-binding for the RV1103B clock driver is shared with the clock-
driver branch going into the clock-tree.

Pull clk updates from Stephen Boyd:
"Not much changed in the clk framework this time except the clk.h
consumer API moved the context saving APIs around to fix a build error
in certain configurations.
There was a change to the core framework for CLK_OPS_PARENT_ENABLE
behavior during registration, but it wrecked existing drivers that
didn't expect things to be turned off during clk registration so it
got reverted.
This cycle is really a large collection of new clk drivers, primarily
for Qualcomm SoCs but also for Amlogic, SpacemiT, Google, and Aspeed.
Another big change in here is support for automatic hardware clock
gating on Samsung SoCs where the clks turn on and off when needed.
Ideally more vendors move to this method for better power savings. The
highlights are in the updates section below.
Beyond all the new drivers we have a bunch of cleanups like converting
drivers from divider_round_rate() to divider_determine_rate() and
using scoped for each OF child loops. Otherwise it's the usual data
fixes and plugging reference leaks, etc. that's all pretty ordinary
but not critical enough to fix until the next release.
New Drivers:
- Qualcomm Kaanapali global, tcsr, rpmh, display, gpu, camera, and
video clk controllers
- Qualcomm SM8750 camera clk controllers
- Qualcomm MSM8940 and SDM439 global clk controllers
- Google GS101 Display Process Unit (DPU) clk controllers
- SpacemiT K3 clk controllers
- Amlogic t7 clk controllers
- Aspeed AST2700 clk controllers
Updates:
- Convert clock dividers from round_rate() to determine_rate()
- Fix sparse warnings, kernel-doc warnings, and plug leaked OF refs
- Automatic hardware clk gating on Google GS101 SoCs
- Amlogic s4 video clks
- CAN-FD clks and resets on Renesas RZ/T2H, RZ/N2H, RZ/V2H, and
RZ/V2N
- Expanded Serial Peripheral Interface (xSPI) clocks and resets on
Renesas RZ/T21H and RZ/N2H
- DMAC, interrupt controller (ICU), SPI, and thermal (TSU) clocks and
resets on Renesas RZ/V2N
- More serial (RSCI) clocks and resets on Renesas RZ/V2H and RZ/V2N
- CPU frequency scaling on T-HEAD TH1520"
