spmi: remove wakeup command before slave probe According to spmi spec a slave powers up into startup state and then transitions into active state. Thus, the wakeup command is not required before calling the slave's probe. The wakeup command is only needed for slaves that are in sleep state after receiving the sleep command.

spmi: Linux driver framework for SPMI 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.

spmi: add command tracepoints for SPMI Add tracepoints to retrieve information about read, write and non-data commands. For performance measurement support tracepoints are added at the beginning and at the end of transfers. Following is a list showing the new tracepoint events. The "cmd" parameter here represents the opcode, SID, and full 16-bit address. spmi_write_begin: cmd and data buffer. spmi_write_end : cmd and return value. spmi_read_begin : cmd. spmi_read_end : cmd, return value and data buffer. spmi_cmd : cmd. The reason that cmd appears at both the beginning and at the end event is that SPMI drivers can request commands concurrently. cmd helps in matching the corresponding events. SPMI tracepoints can be enabled like: echo 1 >/sys/kernel/debug/tracing/events/spmi/enable and will dump messages that can be viewed in /sys/kernel/debug/tracing/trace that look like: ... spmi_read_begin: opc=56 sid=00 addr=0x0000 ... spmi_read_end: opc=56 sid=00 addr=0x0000 ret=0 len=02 buf=0x[01-40] ... spmi_write_begin: opc=48 sid=00 addr=0x0000 len=3 buf=0x[ff-ff-ff] Suggested-by: Sagar Dharia <sdharia@codeaurora.org> Acked-by: Steven Rostedt <rostedt@goodmis.org> Reviewed-by: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: Gilad Avidov <gavidov@codeaurora.org> Signed-off-by: Ankit Gupta <ankgupta@codeaurora.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

spmi: Linux driver framework for SPMI 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.

spmi: do not use bus internal data The variable p is a data structure which is used by the driver core internally and it is not expected that busses will be directly accessing these driver core internal only data.
