regmap: i3c: Add non-devm regmap_init_i3c() helper

2026-04-10T10:46:15+00:00

Add __regmap_init_i3c() and the corresponding regmap_init_i3c() macro to allow creating a regmap for I3C devices without using the device-managed version. This mirrors the pattern already established for other buses such as I2C, SPI and so on, giving drivers more flexibility when the regmap lifetime is not directly tied to the device.

regmap: i3c: switch to use i3c_xfer from i3c_priv_xfer

2025-12-02T16:33:02+00:00

Switch to use i3c_xfer instead of i3c_priv_xfer because framework will update to support HDR mode. i3c_priv_xfer is now an alias of i3c_xfer. Replace i3c_device_do_priv_xfers() with i3c_device_do_xfers(..., I3C_SDR) to align with the new API. Prepare for removal of i3c_priv_xfer and i3c_device_do_priv_xfers().

regmap: i3c: Use ARRAY_SIZE()

regmap: Constify static regmap_bus structs

2022-04-04T07:41:50+00:00

The only usage of these is to pass their address to __regmap_init() or __devm_regmap_init(), both which takes pointers to const struct regmap_bus. Make them const to allow the compiler to put them in read-only memory.
