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.

soc/tegra: cbb: Fix cross-fabric target timeout lookup

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

[ Upstream commit a5f51b04cbb3ae0f9cb2c4488952b775ebb0ccbf ] When a fabric receives an error interrupt, the error may have occurred on a different fabric. The target timeout lookup was using the wrong base address (cbb->regs) with offsets from a different fabric's target map, causing a kernel page fault. Unable to handle kernel paging request at virtual address ffff80000954cc00 pc : tegra234_cbb_get_tmo_slv+0xc/0x28 Call trace: tegra234_cbb_get_tmo_slv+0xc/0x28 print_err_notifier+0x6c0/0x7d0 tegra234_cbb_isr+0xe4/0x1b4 Add tegra234_cbb_get_fabric() to look up the correct fabric device using fab_id, and use its base address for accessing target timeout registers.

soc/tegra: cbb: Fix incorrect ARRAY_SIZE in fabric lookup tables

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

[ Upstream commit 499f7e5ebbdd9ff0c4d532b1c432f8a61ff585b3 ] Fix incorrect ARRAY_SIZE usage in fabric lookup tables which could cause out-of-bounds access during target timeout lookup.

soc/tegra: cbb: Set ERD on resume for err interrupt

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

[ Upstream commit b6ff71c5d1d4ad858ddf6f39394d169c96689596 ] Set the Error Response Disable (ERD) bit to mask SError responses and use interrupt-based error reporting. When the ERD bit is set, inband error responses to the initiator via SError are suppressed, and fabric errors are reported via an interrupt instead. The register is set during boot but the info is lost during system suspend and needs to be set again on resume.

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
