2022-05-06soc: qcom: pdr: use static for servreg_* variablesTom Rix1-10/+10
Sparse reports this repesentative issue pdr_internal.h:31:22: warning: symbol 'servreg_location_entry_ei' was not declared. Should it be static? Similar for other servreg_* Global variables should not be defined in header files. This only works because pdr_internal.h is only included by pdr_interface.c. Single file use variables should be static so add static to their storage-class specifiers.

In some cases the DT binding will fully describe the set of available RPMh power-domains, but there is no reason for exposing them all in the implementation.

2022-04-19bus: add driver for initializing the SSC bus on (some) qcom SoCsMichael Srba3-0/+401
Add bindings for the AHB bus which exposes the SSC (Snapdragon Sensor Core) block in the global address space. This bus (and the SSC block itself) is present on certain qcom SoCs. In typical configuration, this bus (as some of the clocks and registers that we need to manipulate) is not accessible to Linux, and the resources on this bus are indirectly accessed by communicating with a hexagon CPU core residing in the SSC block. In this configuration, the hypervisor is the one performing the bus initialization for the purposes of bringing the hexagon CPU core out of reset. However, it is possible to change the configuration, in which case this driver will initialize the bus. In combination with drivers for resources on the SSC bus, this driver can aid in debugging, and for example with a TLMM driver can be used to directly access SSC-dedicated GPIO pins, removing the need to commit to a particular usecase during hw design. Finally, until open firmware for the hexagon core is available, this approach allows for using sensors hooked up to SSC-dedicated GPIO pins on mainline Linux simply by utilizing the existing in-tree drivers for these sensors.

To move the list iterator variable into the list_for_each_entry_*() macro in the future it should be avoided to use the list iterator variable after the loop body. To *never* use the list iterator variable after the loop it was concluded to use a separate iterator variable instead of a found boolean [1]. This removes the need to use a found variable and simply checking if the variable was set, can determine if the break/goto was hit.

2022-04-03Revert "clk: Drop the rate range on clk_put()"Stephen Boyd2-136/+14
This reverts commit 7dabfa2bc4803eed83d6f22bd6f045495f40636b. There are multiple reports that this breaks boot on various systems. The common theme is that orphan clks are having rates set on them when that isn't expected. Let's revert it out for now so that -rc1 boots.

This log message was accidentally chopped off. I was wondering why this happened, but checking the ML log, Mark precisely followed my suggestion [1]. I just used "..." because I was too lazy to type the sentence fully. Sorry for the confusion.
