2017-06-27usb: typec: Add support for UCSI interfaceHeikki Krogerus
UCSI - USB Type-C Connector System Software Interface - is a specification that defines set of registers and data structures for controlling the USB Type-C ports. It's designed for systems where an embedded controller (EC) is in charge of the USB Type-C PHY or USB Power Delivery controller. It is designed for systems with EC, but it is not limited to them, and for example some USB Power Delivery controllers will use it as their direct control interface. With UCSI the EC (or USB PD controller) acts as the port manager, implementing all USB Type-C and Power Delivery state machines. The OS can use the interfaces for reading the status of the ports and controlling basic operations like role swapping. The UCSI specification highlights the fact that it does not define the interface method (PCI/I2C/ACPI/etc.). Therefore the driver is implemented as library and every supported interface method needs its own driver. Driver for ACPI is provided in separate patch following this one. The initial driver includes support for all required features from UCSI specification version 1.0 (getting connector capabilities and status, and support for power and data role swapping), but none of the optional UCSI features (alternate modes, power source capabilities, and cable capabilities).

2017-06-19mfd: intel_soc_pmic_bxtwc: Use chained IRQs for second level IRQ chipsKuppuswamy Sathyanarayanan
Whishkey cove PMIC has support to mask/unmask interrupts at two levels. At first level we can mask/unmask interrupt domains like TMU, GPIO, ADC, CHGR, BCU THERMAL and PWRBTN and at second level, it provides facility to mask/unmask individual interrupts belong each of this domain. For example, in case of TMU, at first level we have TMU interrupt domain, and at second level we have two interrupts, wake alarm, system alarm that belong to the TMU interrupt domain. Currently, in this driver all first level IRQs are registered as part of IRQ chip(bxtwc_regmap_irq_chip). By default, after you register the IRQ chip from your driver, all IRQs in that chip will masked and can only be enabled if that IRQ is requested using request_irq() call. This is the default Linux IRQ behavior model. And whenever a dependent device that belongs to PMIC requests only the second level IRQ and not explicitly unmask the first level IRQ, then in essence the second level IRQ will still be disabled. For example, if TMU device driver request wake_alarm IRQ and not explicitly unmask TMU level 1 IRQ then according to the default Linux IRQ model, wake_alarm IRQ will still be disabled. So the proper solution to fix this issue is to use the chained IRQ chip concept. We should chain all the second level chip IRQs to the corresponding first level IRQ. To do this, we need to create separate IRQ chips for every group of second level IRQs. In case of TMU, when adding second level IRQ chip, instead of using PMIC IRQ we should use the corresponding first level IRQ. So the following code will change from ret = regmap_add_irq_chip(pmic->regmap, pmic->irq, ...) to, virq = regmap_irq_get_virq(&pmic->irq_chip_data, BXTWC_TMU_LVL1_IRQ); ret = regmap_add_irq_chip(pmic->regmap, virq, ...) In case of Whiskey Cove Type-C driver, Since USBC IRQ is moved under charger level2 IRQ chip. We should use charger IRQ chip(irq_chip_data_chgr) to get the USBC virtual IRQ number.

2017-06-07ACPI: Switch to use generic guid_t in acpi_evaluate_dsm()Andy Shevchenko
acpi_evaluate_dsm() and friends take a pointer to a raw buffer of 16 bytes. Instead we convert them to use guid_t type. At the same time we convert current users. acpi_str_to_uuid() becomes useless after the conversion and it's safe to get rid of it. Acked-by: Rafael J.

User space applications in some cases have the need to enforce a specific port type(DFP/UFP/DRP). This change allows userspace to attempt setting the desired port type. Low level drivers can however reject the request if the specific port type is not supported.

If USB PD contract is established after creation of the partner, the power delivery support attribute of the partner needs to be updated separately. This can be done in typec_set_pwr_opmode() by checking if the port has already partner and updating the value if it does.
