soc/tegra: pmc: Add kerneldoc for wake-up variables

2026-05-23T11:09:03+00:00

[ Upstream commit e6ad1988e56834d641ba4aa0d58970723c1c9c9b ] Commit e6d96073af68 ("soc/tegra: pmc: Fix unsafe generic_handle_irq() call") added the variables 'wake_work' and 'wake_status' to the 'tegra_pmc' structure but did not add the associated kerneldoc for these new variables. Add the kerneldoc for these variables. Fixes: e6d96073af68 ("soc/tegra: pmc: Fix unsafe generic_handle_irq() call") Signed-off-by: Jon Hunter Signed-off-by: Thierry Reding Signed-off-by: Sasha Levin

soc/tegra: pmc: Correct function names in kerneldoc

2026-05-23T11:09:03+00:00

[ Upstream commit ec0e4da5d679f9da1cc198927951f70fdf28f001 ] Commit 70f752ebb08c ("soc/tegra: pmc: Add PMC contextual functions") added the functions devm_tegra_pmc_get() and tegra_pmc_io_pad_power_enable(), but the names of the functions in the associated kerneldoc is incorrect. Update the kerneldoc for these functions to correct their names.

soc/tegra: pmc: Add kerneldoc for reboot notifier

2026-05-23T11:09:03+00:00

[ Upstream commit 21669619e4c17a5f097e0415bc64b1d400c54fcb ] Commit 48b7f802fb78 ("soc/tegra: pmc: Embed reboot notifier in PMC context") added the reboot_notifier structure to the PMC SoC structure but did not update the kerneldoc accordingly. Add this missing kerneldoc description to fix this.

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

soc/tegra: pmc: Add PMC contextual functions

2026-01-18T07:48:30+00:00

Add implementations that take as argument a struct tegra_pmc * for most public APIs, as well as a function to obtain the PMC for any given device. This will allow transitioning away users from relying on a global variable storing the PMC context. Signed-off-by: Thierry Reding

soc/tegra: pmc: Do not rely on global variable

2026-01-18T07:48:30+00:00

The reset action for changing the suspend mode back on failure can take a context-specific data argument that can be set to the PMC context in order to avoid relying on a global variable. Signed-off-by: Thierry Reding

soc/tegra: pmc: Use driver-private data

2026-01-18T07:48:30+00:00

Instead of relying on a global variable for the PMC context, use the driver-private data for sysfs attributes. Signed-off-by: Thierry Reding

soc/tegra: pmc: Use PMC context embedded in powergates

2026-01-18T07:48:29+00:00

The powergates exposed by the PMC have a pointer to the PMC context embedded. Use that embedded reference instead of relying on a global variable. For the core power domain a new structure needs to be introduced to wrap the generic PM domain and store the PMC context. Signed-off-by: Thierry Reding

soc/tegra: pmc: Pass PMC context as debugfs data

2026-01-18T07:48:29+00:00

Each debugfs file can have private data associated with it. Use this to pass the PMC context instead of relying on a global variable. Signed-off-by: Thierry Reding
