soc: ti: k3-socinfo: Do not use syscon helper to build regmap

2025-05-29T09:02:36+00:00

[ Upstream commit a5caf03188e44388e8c618dcbe5fffad1a249385 ] The syscon helper device_node_to_regmap() is used to fetch a regmap registered to a device node. It also currently creates this regmap if the node did not already have a regmap associated with it. This should only be used on "syscon" nodes. This driver is not such a device and instead uses device_node_to_regmap() on its own node as a hacky way to create a regmap for itself. This will not work going forward and so we should create our regmap the normal way by defining our regmap_config, fetching our memory resource, then using the normal regmap_init_mmio() function.

soc: ti: smartreflex: Use IRQF_NO_AUTOEN flag in request_irq()

2024-12-05T13:01:25+00:00

[ Upstream commit 16a0a69244240cfa32c525c021c40f85e090557a ] If request_irq() fails in sr_late_init(), there is no need to enable the irq, and if it succeeds, disable_irq() after request_irq() still has a time gap in which interrupts can come. request_irq() with IRQF_NO_AUTOEN flag will disable IRQ auto-enable when request IRQ.

soc: ti: pm33xx: do device_node auto cleanup

Use scope based cleanup instead of manual of_node_put() calls, hence simplifying the handling of error paths. Suggested-by: Julia Lawall Signed-off-by: Kousik Sanagavarapu Link: https://lore.kernel.org/r/20240825085714.10736-5-five231003@gmail.com Signed-off-by: Nishanth Menon

soc: ti: knav_qmss_queue: do device_node auto cleanup

2024-08-28T17:18:02+00:00

Use scope based cleanup, instead of manual of_node_put() calls, which automatically free()s "struct device_node". While at it, refactor the code from knav_queue_probe() into the separate functions to make auto cleanup look more neat. Doing the cleanup this way has the advantage of reducing the chance of memory leaks in case we need to read from new OF nodes in the future when we probe.

2024-08-28T17:18:02+00:00

Use scope based cleanup instead of manual of_node_put() calls, hence simplifying the handling of error paths at various places. While at it, use dev_err_probe() instead of dev_err() in all the code paths touched.

soc: ti: pruss: factor out memories setup

2024-08-28T17:18:02+00:00

Factor out memories setup code from probe() into a new function pruss_of_setup_memories(). This sets the stage for introducing auto cleanup of the device node (done in the subsequent patch), since the clean up depends on the scope of the pointer and factoring out code into a separate function obviously limits the scope of the various variables used in that function. Apart from the above, this change also has the advantage of making the code look more neat. While at it, use dev_err_probe() instead of plain dev_err() as this new function is called by the probe().

soc: ti: knav: Use of_property_read_variable_u32_array()

2024-08-06T21:29:13+00:00

There's no need to get the length of an DT array property before parsing the array. of_property_read_variable_u32_array() takes a minimum and maximum length and returns the actual length (or error code). This is part of a larger effort to remove callers of of_find_property() and similar functions. of_find_property() leaks the DT struct property and data pointers which is a problem for dynamically allocated nodes which may be freed.

soc: ti: knav: Drop unnecessary check for property presence

2024-08-06T21:29:04+00:00

of_property_read_u32() returns -EINVAL if a property is not present, so the preceding check for presence with of_get_property() can be dropped. This is part of a larger effort to remove callers of of_get_property() and similar functions. of_get_property() leaks the DT struct property and data pointers which is a problem for dynamically allocated nodes which may be freed.
