6ad844d739 clk: qcom: rpmh: rename VRM clock data
RPMH VRM clocks are frequently shared between several platforms. It
makes little sense to encode the SoC name into the clock name, if the
same clock is used for other SoCs.

Rework the VRM clock definitions to add resource-specific suffix. Keep
the userspace-visible clock name, but encode the part of cmd resource
and the divider into the variable name. This also make it obvious which
variant is used, making the code less error-prone.

49e4aa233c clk: qcom: rpmh: support separate symbol name for the RPMH clocks
Both ARC and VRM clocks have minor differences between platforms.
However using SoC names directly results in duplication, confusion and
occasional errors. Next patches are going to drop the SoC names and
encode these differences into the clock names.
To keep the system clock names (visible to userspace) intact, add
separate symbol names that are used in the code.

dad4e7fda4 clk: qcom: clk-rpmh: Wait for completion when enabling clocks
The current implementation always uses rpmh_write_async, which doesn't
wait for completion. That's fine for disable requests since there's no
immediate need for the clocks and they can be disabled in the
background. However, for enable requests we need to ensure the clocks
are actually enabled before returning to the client. Otherwise, clients
can end up accessing their HW before the necessary clocks are enabled,
which can lead to bus errors.

Use the synchronous version of this API (rpmh_write) for enable requests
in the active set to ensure completion.

Completion isn't required for sleep/wake sets, since they don't take
effect until after we enter sleep. All rpmh requests are automatically
flushed prior to entering sleep.

f5790382ed clk: qcom: rpmh: Reuse sdm845 clks for sm8150
The SM8150 list of clks is almost the same as the list for SDM845,
except there isn't an IPA clk. Just point to the SDM845 clks from the
SM8150 list for now so we can reduce the amount of struct bloat in this
driver.

a703d279c5 We have a small collection of core framework updates this time, mostly around
clk registration by clk providers and debugfs "nice to haves" for rate
 constraints. I'll highlight that we're now setting the clk_init_data pointer
 inside struct clk_hw to NULL during clk_register(), which may break some
 drivers that thought they could use that pointer during normal operations. That
 change has been sitting in next for a while now but maybe something is still
 broken. We'l see. Other than that the core framework changes aren't invasive
 and they're fixing bugs, simplifying, and making things better.
 
 On the clk driver side we got the usual addition of new SoC support, new
 features for existing drivers, and bug fixes scattered throughout. The biggest
 diffstat is the Amlogic driver that gained CPU clk support in addition to
 migrating to the new way of specifying clk parents. After that the Qualcomm,
 i.MX, Mediatek, and Rockchip clk drivers got support for various new SoCs and
 clock controllers from those vendors.
 
 Core:
  - Drop NULL checks in clk debugfs
  - Add min/max rates to clk debugfs
  - Set clk_init_data pointer inside clk_hw to NULL after registration
  - Make clk_bulk_get_all() return an 'id' corresponding to clock-names
  - Evict parents from parent cache when they're unregistered
 
 New Drivers:
  - Add clock driver for i.MX8MN SoCs
  - Support aspeed AST2600 SoCs
  - Support for Mediatek MT6779 SoCs
  - Support qcom SM8150 GCC and RPMh clks
  - Support qcom QCS404 WCSS clks
  - Add CPU clock support for Armada 7K/8K (specifically AP806 and AP807)
  - Addition of clock driver for Rockchip rk3308 SoCs
 
 Updates:
  - Add regulator support to the cdce925 clk driver
  - Add support for Raspberry Pi 4 bcm2711 SoCs
  - Add SDIO gate support to aspeed driver
  - Add missing of_node_put() calls in various clk drivers
  - Migrate Amlogic driver to new clock parent description method
  - Add DVFS support to Amlogic Meson g12
  - Add Amlogic Meson g12a reset support to the axg audio clock controller
  - Add sm1 support to the Amlogic Meson g12a clock controller
  - Switch i.MX8MM clock driver to platform driver
  - Add Hifi4 DSP related clocks for i.MX8QXP SoC
  - Fix Audio PLL setting and parent clock for USB
  - Misc i.MX8 clock driver improvements and corrections
  - Set floor ops for Qualcomm SD clks so that rounding works
  - Fix "always-on" Clock Domains on Renesas R-Car M1A, RZ/A1, RZ/A2, and RZ/N1
  - Enable the Allwinner V3 SoC and fix the i2s clock for H6

04053f4d23 clk: qcom: clk-rpmh: Add IPA clock support
The clk-rpmh driver only supports on and off RPMh clock resources. Let's
extend the driver by adding support for clocks that are managed by a
different type of RPMh resource known as Bus Clock Manager(BCM). The BCM
is a configurable shared resource aggregator that scales performance
based on a set of frequency points. The Qualcomm IP Accelerator (IPA)
clock is an example of a resource that is managed by the BCM and this a
requirement from the IPA driver in order to scale its core clock.
