2023-12-15spmi: Introduce device-managed functionsFei Shao1-1/+1
Utilize the managed resource (devres) framework and add the following devm_* helpers for the SPMI driver: - devm_spmi_controller_alloc() - devm_spmi_controller_add() [[email protected]: Rename to spmi-devres for module niceness, slap on GPL module license] Signed-off-by: Fei Shao <[email protected]> Link: https://lore.kernel.org/r/[email protected] Reviewed-by: AngeloGioacchino Del Regno <[email protected]> Signed-off-by: Stephen Boyd <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Greg Kroah-Hartman <[email protected]>

2014-02-15spmi: Add MSM PMIC Arbiter SPMI controllerKenneth Heitke1-0/+2
Qualcomm's PMIC Arbiter SPMI controller functions as a bus master and is used to communication with one or more PMIC (slave) devices on the SPMI bus. The PMIC Arbiter is actually a hardware wrapper around the SPMI controller that provides concurrent and autonomous PMIC access to various entities that need to communicate with the PMIC. The SPMI controller hardware handles all of the SPMI bus activity (bus arbitration, sequence start condition, transmission of frames, etc). This software driver uses the PMIC Arbiter register interface to initiate command sequences on the SPMI bus. The status register is read to determine when the command sequence has completed and whether or not it completed successfully.

2014-02-15spmi: Linux driver framework for SPMIKenneth Heitke1-0/+4
System Power Management Interface (SPMI) is a specification developed by the MIPI (Mobile Industry Process Interface) Alliance optimized for the real time control of Power Management ICs (PMIC). SPMI is a two-wire serial interface that supports up to 4 master devices and up to 16 logical slaves. The framework supports message APIs, multiple busses (1 controller per bus) and multiple clients/slave devices per controller.
