2025-05-17clk: qcom: rpmh: make clkaN optionalPengyu Luo
On SM8650, clkaN are missing in cmd-db for some specific devices. This caused a boot failure. Printing log during initramfs phase, I found [ 0.053281] clk-rpmh 17a00000.rsc:clock-controller: missing RPMh resource address for clka1 Adding the optional property to avoid probing failure which causes countless deferred probe. In the downstream tree,similar workarounds are introduced for SM7635, SM8550, SM8635, SM8650, SM8750.

2025-01-15clk: Use str_enable_disable-like helpersKrzysztof Kozlowski
Replace ternary (condition ? "enable" : "disable") syntax with helpers from string_choices.h because: 1. Simple function call with one argument is easier to read. Ternary operator has three arguments and with wrapping might lead to quite long code. 2. Is slightly shorter thus also easier to read. 3. It brings uniformity in the text - same string. 4. Allows deduping by the linker, which results in a smaller binary file.

2023-07-19clk: Explicitly include correct DT includesRob Herring
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2020-03-09clk: qcom: clk-rpmh: Wait for completion when enabling clocksMike Tipton
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.
