From d17baf052cbbd793784bc0f4fc613459afa4b883 Mon Sep 17 00:00:00 2001 From: Peng Fan Date: Fri, 23 Aug 2024 17:05:23 +0800 Subject: input: keyboard: support i.MX95 BBM module The BBM module provides BUTTON feature. To i.MX95, this module is managed by System Manager and exported using System Management Control Interface(SCMI). Linux could use i.MX SCMI BBM Extension protocol to use BUTTON feature. This driver is to use SCMI interface to enable pwrkey.

"enable" : "disable") syntax with helpers from string_choices.h because: 1. Simple function call with one argument is easier to read. Ternary operator has three arguments and with wrapping might lead to quite long code. 2. Is slightly shorter thus also easier to read. 3. It brings uniformity in the text - same string. 4. Allows deduping by the linker, which results in a smaller binary file.

However synaptics sub-driver tries to access psmouse instance presumably associated with the pass-through port to figure out if only 1 byte of response or entire protocol packet needs to be forwarded to the pass-through port and may crash if psmouse instance has not been attached to the port yet. Fix the crash by introducing open() and close() methods for the port and check if the port is open before trying to access psmouse instance. Because psmouse calls serio_open() only after attaching psmouse instance to serio port instance this prevents the potential crash.
