soc: qcom: aoss: compare against normalized cooling state

2026-06-01T15:29:35+00:00

[ Upstream commit cd3c4670db3ffe997be9548c7a9db3952563cf14 ] qmp_cdev_set_cur_state() normalizes the requested state to a boolean (cdev_state = !!state). The existing early-return check compares qmp_cdev->state == state, which can be wrong if state is non-boolean (any non-zero value). Compare qmp_cdev->state against cdev_state instead, so the check matches the effective state and avoids redundant updates.

soc: qcom: ocmem: return -EPROBE_DEFER is ocmem is not available

[ Upstream commit 91b59009c7d48b58dbc50fecb27f2ad20749a05a ] If OCMEM is declared in DT, it is expected that it is present and handled by the driver. The GPU driver will ignore -ENODEV error, which typically means that OCMEM isn't defined in DT. Let ocmem return -EPROBE_DEFER if it supposed to be used, but it is not probed (yet).

soc: fsl: qbman: fix race condition in qman_destroy_fq

2026-04-18T08:31:01+00:00

[ Upstream commit 014077044e874e270ec480515edbc1cadb976cf2 ] When QMAN_FQ_FLAG_DYNAMIC_FQID is set, there's a race condition between fq_table[fq->idx] state and freeing/allocating from the pool and WARN_ON(fq_table[fq->idx]) in qman_create_fq() gets triggered. Indeed, we can have: Thread A Thread B qman_destroy_fq() qman_create_fq() qman_release_fqid() qman_shutdown_fq() gen_pool_free() -- At this point, the fqid is available again -- qman_alloc_fqid() -- so, we can get the just-freed fqid in thread B -- fq->fqid = fqid; fq->idx = fqid * 2; WARN_ON(fq_table[fq->idx]); fq_table[fq->idx] = fq; fq_table[fq->idx] = NULL; And adding some logs between qman_release_fqid() and fq_table[fq->idx] = NULL makes the WARN_ON() trigger a lot more. To prevent that, ensure that fq_table[fq->idx] is set to NULL before gen_pool_free() is called by using smp_wmb().

pmdomain: bcm: bcm2835-power: Increase ASB control timeout

2026-04-18T08:31:00+00:00

[ Upstream commit b826d2c0b0ecb844c84431ba6b502e744f5d919a ] The bcm2835_asb_control() function uses a tight polling loop to wait for the ASB bridge to acknowledge a request. During intensive workloads, this handshake intermittently fails for V3D's master ASB on BCM2711, resulting in "Failed to disable ASB master for v3d" errors during runtime PM suspend. As a consequence, the failed power-off leaves V3D in a broken state, leading to bus faults or system hangs on later accesses. As the timeout is insufficient in some scenarios, increase the polling timeout from 1us to 5us, which is still negligible in the context of a power domain transition. Also, replace the open-coded ktime_get_ns()/ cpu_relax() polling loop with readl_poll_timeout_atomic().

pmdomain: bcm: bcm2835-power: Fix broken reset status read

2026-04-18T08:30:59+00:00

[ Upstream commit 550bae2c0931dbb664a61b08c21cf156f0a5362a ] bcm2835_reset_status() has a misplaced parenthesis on every PM_READ() call. Since PM_READ(reg) expands to readl(power->base + (reg)), the expression: PM_READ(PM_GRAFX & PM_V3DRSTN) computes the bitwise AND of the register offset PM_GRAFX with the bitmask PM_V3DRSTN before using the result as a register offset, reading from the wrong MMIO address instead of the intended PM_GRAFX register. The same issue affects the PM_IMAGE cases. Fix by moving the closing parenthesis so PM_READ() receives only the register offset, and the bitmask is applied to the value returned by the read.

soc: ti: pruss: Fix double free in pruss_clk_mux_setup()

2026-03-04T12:20:16+00:00

[ Upstream commit 80db65d4acfb9ff12d00172aed39ea8b98261aad ] In the pruss_clk_mux_setup(), the devm_add_action_or_reset() indirectly calls pruss_of_free_clk_provider(), which calls of_node_put(clk_mux_np) on the error path. However, after the devm_add_action_or_reset() returns, the of_node_put(clk_mux_np) is called again, causing a double free. Fix by returning directly, to avoid the duplicate of_node_put().

commit 32200f4828de9d7e6db379909898e718747f4e18 upstream. Make sure to drop the reference taken to the canvas platform device when looking up its driver data.
