From af7e9069543aabd415d7c543f3f89b143ac1a932 Mon Sep 17 00:00:00 2001 From: Jacob Pan Date: Mon, 6 Oct 2014 21:17:14 -0700 Subject: mfd: axp20x: Extend axp20x to support axp288 pmic X-Powers AXP288 is a customized PMIC for Intel Baytrail-CR platforms. Similar to AXP202/209, AXP288 comes with USB charger, more LDO and BUCK channels, and AD converters. It also provides extended status and interrupt reporting capabilities than the devices currently supported in axp20x.c. In addition to feature extension, this patch also adds ACPI binding for enumeration. This consolidated driver should support more X-Powers' PMICs in both device tree and ACPI enumerated platforms.

Details about the device can be found here: https://www.diolan.com/i2c/i2c_interface.html. Information about the USB protocol can be found in the Programmer's Reference Manual [1], see section 1.7. Because the hardware has a single transmit endpoint and a single receive endpoint the communication between the various DLN2 drivers and the hardware will be muxed/demuxed by this driver. Each DLN2 module will be identified by the handle field within the DLN2 message header. If a DLN2 module issues multiple commands in parallel they will be identified by the echo counter field in the message header. The DLN2 modules can use the dln2_transfer() function to issue a command and wait for its response. They can also register a callback that is going to be called when a specific event id is generated by the device (e.g. GPIO interrupts). The device uses handle 0 for sending events.
