ARM: rockchip: keep reset control around

2026-05-26T21:20:39+00:00

Do not put the reset control, retain exclusive control over it. After turning on a CPU, the corresponding reset line must stay deasserted. This also avoids calling reset_control_put() before workqueues are operational.

ARM: rockchip: remove REGULATOR conditional to PM

ARM: rockchip: fix kernel hang during smp initialization

2025-07-14T13:38:40+00:00

In order to bring up secondary CPUs main CPU write trampoline code to SRAM. The trampoline code is written while secondary CPUs are powered on (at least that true for RK3188 CPU). Sometimes that leads to kernel hang. Probably because secondary CPU execute trampoline code while kernel doesn't expect. The patch moves SRAM initialization step to the point where all secondary CPUs are powered down. That fixes rarely hangs on RK3188: [ 0.091568] CPU0: thread -1, cpu 0, socket 0, mpidr 80000000 [ 0.091996] rockchip_smp_prepare_cpus: ncores 4 Signed-off-by: Alexander Kochetkov Link: https://lore.kernel.org/r/20250703140453.1273027-1-al.kochet@gmail.com Signed-off-by: Heiko Stuebner

ARM: rockchip: Drop unused includes

2023-08-12T08:31:00+00:00

Several includes are not needed, so drop them. of_platform.h is not needed, but it implicitly includes of.h which is needed.

ARM: mm: Make virt_to_pfn() a static inline

2023-05-29T09:27:08+00:00

Making virt_to_pfn() a static inline taking a strongly typed (const void *) makes the contract of a passing a pointer of that type to the function explicit and exposes any misuse of the macro virt_to_pfn() acting polymorphic and accepting many types such as (void *), (unitptr_t) or (unsigned long) as arguments without warnings. Doing this is a bit intrusive: virt_to_pfn() requires PHYS_PFN_OFFSET and PAGE_SHIFT to be defined, and this is defined in , so this must be included *before* . The use of macros were obscuring the unclear inclusion order here, as the macros would eventually be resolved, but a static inline like this cannot be compiled with unresolved macros. The naive solution to include at the top of does not work, because sometimes includes at the end of itself, which would create a confusing inclusion loop. So instead, take the approach to always unconditionally include at the end of arch/arm uses explicitly in a lot of places, however it turns out that if we just unconditionally include into and switch all inclusions of to instead, we enforce the right order and will always have access to the definitions. Put an inclusion guard in place making it impossible to include explicitly.

ARM: rockchip: Add missing of_node_put() in rockchip_suspend_init()

2022-06-17T17:05:51+00:00

In rockchip_suspend_init(), of_find_matching_node_and_match() will return a node pointer with refcount incremented. We should use of_node_put() in fail path or when it is not used anymore.
