* soc: renesas: renesas-soc: Release 'chipid' from ioremap()Li Yang2023-04-041-1/+4
| | | | | | | | | | | | | | | | | | | Smatch reports: drivers/soc/renesas/renesas-soc.c:536 renesas_soc_init() warn: 'chipid' from ioremap() not released on lines: 475. If soc_dev_atrr allocation is failed, function renesas_soc_init() will return without releasing 'chipid' from ioremap(). Fix this by adding function iounmap().

| | | | | | | | | | | | | | The driver can match only via the DT table so the table should be always used and the of_match_ptr does not have any sense (this also allows ACPI matching via PRP0001, even though it might not be relevant here).

|/ | | | | | | | | | | | | | | | | | | | The OF_POPULATED flag was set to let fw_devlink know that the device tree node will not have a struct device created for it. This information is used by fw_devlink to avoid deferring the probe of consumers of this device tree node. Let's use fwnode_dev_initialized() instead because it achieves the same effect without using OF specific flags. This allows more generic code to be written in driver core.

| | | | | | | | | | | | | | | | | Currently renesas_soc_init() scans the whole device tree up to three times, to find a device node describing a product register. Furthermore, the product register handling for the different variants is very similar, with the major difference being the location of the product bitfield inside the product register. Reduce scanning to a single pass using of_find_matching_node_and_match() instead. Switch to a common handling of product registers, by storing the intrinsics of each product register type in the data field of the corresponding match entry.

* soc: renesas: rmobile-sysc: Mark fwnode when PM domain is addedGeert Uytterhoeven2021-03-081-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently, there are two drivers binding to the R-Mobile System Controller (SYSC): - The rmobile-sysc driver registers PM domains from a core_initcall(), and does not use a platform driver, - The optional rmobile-reset driver registers a reset handler, and does use a platform driver. As fw_devlink only considers devices, commit bab2d712eeaf9d60 ("PM: domains: Mark fwnodes when their powerdomain is added/removed") works only for PM Domain drivers where the DT node is a real device node, and not for PM Domain drivers using a hierarchical representation inside a subnode. Hence if fw_devlink is enabled, probing of on-chip devices that are part of the SYSC PM domain is deferred until the optional rmobile-reset driver has been bound. If the rmobile-reset driver is not available, this will never happen, and thus lead to complete system boot failures. Fix this by explicitly marking the fwnode initialized.

* soc: renesas: rcar-sysc: Mark device node OF_POPULATED after initGeert Uytterhoeven2021-01-291-0/+2
| | | | | | | | | | | | | | | | | | | | | | The R-Car System Controller (SYSC) driver registers PM domains from an early_initcall(). It does not use a platform driver, as secondary CPU startup on R-Car H1 needs to control the CPU power domains, before initialization of the driver framework. As fw_devlink only considers devices, it does not know that the System Controller is ready. Hence probing of on-chip devices that are part of the SYSC PM domain fails if fw_devlink is enabled: probe deferral - supplier e6180000.system-controller not ready Fix this by setting the OF_POPULATED flag for the SYSC device node after successful initialization. This will make of_link_to_phandle() ignore the SYSC device node as a dependency, and consumer devices will be probed again.
