pmdomain: ti: Select PM_GENERIC_DOMAINS

2025-08-20T16:30:22Z

[ Upstream commit fcddcb7e8f38a40db99f87a962c5d0a153a76566 ] Select PM_GENERIC_DOMAINS instead of depending on it to ensure it is always enabled when TI_SCI_PM_DOMAINS is selected. Since PM_GENERIC_DOMAINS is an implicit symbol, it can only be enabled through 'select' and cannot be explicitly enabled in configuration. This simplifies the dependency chain and prevents build issues Signed-off-by: Guillaume La Roque Reviewed-by: Nishanth Menon Link: https://lore.kernel.org/r/20250715-depspmdomain-v2-1-6f0eda3ce824@baylibre.com Signed-off-by: Ulf Hansson Signed-off-by: Sasha Levin

pmdomain: ti-sci: Add missing of_node_put() for args.np

2024-12-05T13:01:32Z

[ Upstream commit afc2331ef81657493c074592c409dac7c3cb8ccc ] of_parse_phandle_with_args() needs to call of_node_put() to decrement the refcount of args.np. So, Add the missing of_node_put() in the loop.

pmdomain: ti-sci: Fix duplicate PD referrals

2024-05-03T13:20:05Z

When the dts file has multiple referrers to a single PD (e.g. simple-framebuffer and dss nodes both point to the DSS power-domain) the ti-sci driver will create two power domains, both with the same ID, and that will cause problems as one of the power domains will hide the other one. Fix this checking if a PD with the ID has already been created, and only create a PD for new IDs.

pmdomain: core: constify of_phandle_args in xlate

2024-02-14T09:26:11Z

The xlate callbacks are supposed to translate of_phandle_args to proper provider without modifying the of_phandle_args. Make the argument pointer to const for code safety and readability.

pmdomain: ti: Add a null pointer check to the omap_prm_domain_init

2024-02-14T09:26:11Z

devm_kasprintf() returns a pointer to dynamically allocated memory which can be NULL upon failure. Ensure the allocation was successful by checking the pointer validity. Signed-off-by: Kunwu Chan Link: https://lore.kernel.org/r/20240118054257.200814-1-chentao@kylinos.cn Signed-off-by: Ulf Hansson

pmdomain: ti: add missing of_node_put

2023-10-17T09:42:29Z

for_each_node_with_property performs an of_node_get on each iteration, so a break out of the loop requires an of_node_put.

pmdomain: ti: Move and add Kconfig options to the pmdomain subsystem

2023-10-04T21:41:56Z

The TI_SCI_PM_DOMAINS Kconfig option belongs closer to its corresponding implementation, hence let's move it from the soc subsystem to the pmdomain subsystem. While at it, let's also add a Kconfig option the omap_prm driver, rather than using ARCH_OMAP2PLUS directly.

pmdomain: Rename the genpd subsystem to pmdomain

2023-09-13T09:09:21Z

It has been pointed out that naming a subsystem "genpd" isn't very self-explanatory and the acronym itself that means Generic PM Domain, is known only by a limited group of people. In a way to improve the situation, let's rename the subsystem to pmdomain, which ideally should indicate that this is about so called Power Domains or "PM domains" as we often also use within the Linux Kernel terminology.
