clk: qcom: a53: Corrected frequency multiplier for 1152MHz

2026-07-24T14:03:16+00:00

[ Upstream commit bb56147ea9fce98ebde1d367335ba006cba61fbd ] The 1152MHz frequency entry for the a53 currently selects a multiplier of 62, giving 1190MHz. This changes the mulitiplier to 60 giving the intended 1152MHz.

clk: at91: keep securam node alive while mapping it

2026-07-24T14:03:15+00:00

[ Upstream commit 22fa1c39ba6fe726b547c877c924379b7fee260a ] pmc_register_ops() gets an owned reference to the "atmel,sama5d2-securam" node with of_find_compatible_node(). The success path dropped that reference before passing the node to of_iomap(), leaving of_iomap() to consume a node pointer after the caller had released its reference. Move of_node_put() after of_iomap() so the node remains referenced for the mapping operation. The unavailable-node error path already releases the reference.

clk: scpi: Unregister child clock providers on remove

2026-07-24T14:03:00+00:00

[ Upstream commit b79d9b5747d961516c35ef4d5e91efa579fd3e9a ] SCPI clock providers are registered for each child node in scpi_clk_add(), but scpi_clocks_remove() unregisters the parent node on each iteration. of_clk_del_provider() matches providers by the node used at registration time, so passing the parent node leaves the child providers registered. This leaks the provider allocations and the node references held by the clock provider core. Pass the child node to of_clk_del_provider() so the remove path matches the probe path.

clk: scmi: Fix clock rate rounding

[ Upstream commit d0c81a38d06d446d341532700b3a4a43d3b00eb1 ] While the do_div() helper used for rounding expects its divisor argument to be a 32bits quantity, the currently provided divisor parameter is a 64bit value that, as a consequence, is silently truncated and a possible source of bugs. Fix by using the proper div64_ul helper.

driver core: platform: use generic driver_override infrastructure

2026-06-01T15:43:04+00:00

[ Upstream commit 2b38efc05bf7a8568ec74bfffea0f5cfa62bc01d ] When a driver is probed through __driver_attach(), the bus' match() callback is called without the device lock held, thus accessing the driver_override field without a lock, which can cause a UAF. Fix this by using the driver-core driver_override infrastructure taking care of proper locking internally. Note that calling match() from __driver_attach() without the device lock held is intentional.

clk: visconti: pll: initialize clk_init_data to zero

[ Upstream commit 1603cbb64173a0e9fa7500f2a686f4aa011c58b9 ] Sashiko reported the following: > The struct clk_init_data init is declared on the stack without being > fully zero-initialized. While fields like name, flags, parent_names, > num_parents, and ops are explicitly assigned, the parent_data and > parent_hws fields are left containing stack garbage. clk_core_populate_parent_map() currently prefers the parent names over the parent data and hws, so this isn't a problem at the moment. If that ordering ever changed in the future, then this could lead to some unexpected crashes. Let's just go ahead and make sure that the struct clk_init_data is initialized to zero as a good practice.
