Define "clock-<freq>" as the preferred node name for fixed-clock and fixed-factor-clock where <freq> is the output frequency of the clock. There isn't much of an existing pattern for names of these nodes. The most frequent patterns are a prefix or suffix of "clk", but there's a bunch that don't follow any sort of pattern. We could use "clock-controller-.*", but these nodes aren't really a controller in any way. So let's at least align with part of that and use 'clock-'. For now this only serves as documentation as the schema still allows anything to avoid lots of additional warnings for something low priority to fix. Once a "no deprecated" mode is added to the tools, warnings can be enabled selectively. Signed-off-by:

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

Commit f316cdff ("clk: Annotate struct clk_hw_onecell_data with __counted_by") annotated the hws member of 'struct clk_hw_onecell_data' with __counted_by, which informs the bounds sanitizer about the number of elements in hws, so that it can warn when hws is accessed out of bounds. As noted in that change, the __counted_by member must be initialized with the number of elements before the first array access happens, otherwise there will be a warning from each access prior to the initialization because the number of elements is zero. This occurs in raspberrypi_discover_clocks() due to ->num being assigned after ->hws has been accessed: UBSAN: array-index-out-of-bounds in drivers/clk/bcm/clk-raspberrypi.c:374:4 index 3 is out of range for type 'struct clk_hw *[] __counted_by(num)' (aka 'struct clk_hw *[]') Move the ->num initialization to before the first access of ->hws, which clears up the warning.

RZ/{G2L, V2L, G3S}-based CPG versions have support for saving extra power when clocks are disabled by activating module standby. This is done through MSTOP-specific registers that are part of CPG. Each individual module has one or more bits associated with one MSTOP register (see table "Registers for Module Standby Mode" from HW manuals). Hardware manual associates modules' clocks with one or more MSTOP bits. There are 3 mappings available (identified by researching RZ/G2L, RZ/G3S, RZ/V2L HW manuals): case 1: N clocks mapped to N MSTOP bits (with N={0, ..., X}) case 2: N clocks mapped to 1 MSTOP bit (with N={0, ..., X}) case 3: N clocks mapped to M MSTOP bits (with N={0, ..., X}, M={0, ..., Y}) Case 3 has been currently identified on RZ/V2L for the VCPL4 module. To cover all three cases, the individual platform drivers will provide the clock driver with MSTOP register offsets and associated bits in this register as a bitmask, and the clock driver will apply this bitmask to the proper MSTOP register. The MSTOP support was implemented through power domains. Platform-specific clock drivers will register an array of type struct rzg2l_cpg_pm_domain_init_data, which will be used to instantiate properly the power domains. Signed-off-by: -

The driver will be modified (in the next commits) to be able to specify individual power domain IDs for each IP. The driver will still support #power-domain-cells = <0>, thus, previous users are not affected. The #power-domain-cells = <1> has been instantiated only for RZ/G3S at the moment, as individual platform clock drivers need to be adapted for this to be supported on the rest of the SoCs. Also, the description for #power-domain-cells is updated with links to per-SoC power domain IDs. Signed-off-by:

Cristian Marussi authored
SCMI Clocks descriptors expose an increasing number of properties, thing which, in turn, leads to a varying set of supported CLK operations to be associated with each clock. Providing statically pre-defined CLK operations structs for all the possible combinations of allowed clock features is becoming cumbersome and error-prone. Allocate the per-clock operations descriptors dynamically and populate it with the strictly needed set of operations depending on the advertised clock properties: one descriptor is created for each distinct combination of clock operations, so minimizing the number of clk_ops structures to the strictly minimum needed.
