2017-06-19mfd: intel_soc_pmic_bxtwc: Use chained IRQs for second level IRQ chipsKuppuswamy Sathyanarayanan1-1/+1
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 Shevchenko1-4/+4
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.
