regmap: i3c: switch to use i3c_xfer from i3c_priv_xfer

2025-12-02T16:33:02Z

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: Drop capitalisation in MODULE_DESCRIPTION()

'Regmap' should be spelled as 'regmap'. Update that. Suggested-by: Mark Brown Signed-off-by: Andy Shevchenko Link: https://msgid.link/r/20240410202912.1659275-2-andriy.shevchenko@linux.intel.com Signed-off-by: Mark Brown

regmap: Constify static regmap_bus structs

2022-04-04T07:41:50Z

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.
