reset: Add reset_reset() and reset_reset_bulk() API

2026-06-08T08:50:06Z

Add reset_reset() and reset_reset_bulk() functions to the reset controller API. These functions assert and then deassert reset signals in a single call, providing a convenient way to pulse/toggle a reset line. This mimics the Linux kernel's reset_control_reset() and reset_control_bulk_reset() APIs. The new functions are useful for drivers that need to cycle a reset line during initialization or error recovery but with also passing delay parameter. If a driver implements the rst_reset op, it will be called directly with the delay parameter. Otherwise, the reset core performs reset_assert(), optional udelay(), and reset_deassert() as fallback.

reset: Allow reset_get_by_name() with NULL name

This allows devm_reset_control_get(dev, NULL) to work and get the first reset control, which is common in code ported from Linux. Signed-off-by: Samuel Holland Reviewed-by: Simon Glass Link: https://lore.kernel.org/r/20230122000252.53642-2-samuel@sholland.org

drivers: reset: Add a managed API to get reset controllers from the DT

2020-09-30T15:55:22Z

Add managed functions to get a reset_ctl from the device-tree, based on a name or an index. Also add a managed functions to get a reset_ctl_bulk (array of reset_ctl) from the device-tree. When the device is unbound, the reset controllers are automatically released and the data structure is freed.

reset: Get the RESET by index without device

2019-05-08T19:14:13Z

Getting a RESET by index with device is not straight forward for some use-cases like handling clock operations for child node in parent driver. So we need to process the child node in parent probe via ofnode and process RESET operation for child without udevice but with ofnode. So add reset_get_by_index_nodev() and move the common code in reset_get_by_index_tail() to use for reset_get_by_index() Cc: Stephen Warren Signed-off-by: Jagan Teki Reviewed-by: Simon Glass
