Remove the register DA9062AA_BBAT_CONT (0x0C5) from the DA9061 chip model regmap access ranges. This applies to both da9061_aa_readable_ranges[] and da9061_aa_writeable_ranges[]. This change is to correct the DA9061 chip model and align it with the latest DA9061 Datasheet. This register previously appeared in the DA9061 Datasheet, Revision 3.2, 01-Mar-2016 and has been removed from later DA9061 datasheet from Dialog, Revision 3.3, 04-Apr-2017. Signed-off-by:

On x86 the AXP288 PMIC provides an ACPI OpRegion handler, which must be available before other drivers using it are loaded, which can only be ensured if the MFD, OpRegion and i2c-bus drivers are built-in. Since the AXP20x MFD code is used on non x86 too we cannot simply change this into a bool, I've tried some Kconfig magic with if x86 but I could not get this working correctly, so this commit just documents that this should be built-in on x86, which fixes errors like these during boot: mmc0: SDHCI controller on ACPI [80860F14:00] using ADMA ACPI Error: No handler for Region [REGS] (ffff93543b0cc3a8) [UserDefinedRegion] ACPI Error: Region UserDefinedRegion (ID=143) has no handler (20170119/exfldio-2 ACPI Error: Method parse/execution failed [\_SB.PCI0.I2C7.PMI5.GET] (Node ffff93 ACPI Error: Method parse/execution failed [\_SB.PCI0.SHC1._PS0] (Node ffff93543b acpi 80860F14:02: Failed to change power state to D0 Signed-off-by:

Add mfd driver for Intel CHT Whiskey Cove PMIC, based on various non upstreamed CHT Whiskey Cove PMIC patches. This is a somewhat minimal version which adds irqchip support and cells for: ACPI PMIC opregion support, the i2c-controller driving the external charger irc and the pwrsrc/extcon block. Further cells can be added in the future if/when drivers are upstreamed for them. [The above patch caused a build error on some archetectures] From: Arnd Bergmann <arnd@arndb.de> I ran into a build error on ARM with a platform that has a non-standard clk implementation: drivers/clk/clk.o: In function `clk_disable': clk.c:(.text.clk_disable+0x0): multiple definition of `clk_disable' arch/arm/mach-omap1/clock.o:clock.c:(.text.clk_disable+0x0): first defined here drivers/clk/clk.o: In function `clk_enable': clk.c:(.text.clk_enable+0x0): multiple definition of `clk_enable' arch/arm/mach-omap1/clock.o:clock.c:(.text.clk_enable+0x0): first defined here The problem is a device driver that uses 'select COMMON_CLK', which is generally a bad idea: selecting a subsystem should only be done from a platform, otherwise we run into circular dependencies. The same driver also selects 'GPIOLIB' and 'I2C', which has a similar effect. This turns all three into 'depends on', as it should be. Finally, we can limit the build to x86, unless we are compile testing. First patch: Signed-off-by:

The Crystal Cove PMIC provides an ACPI OPRegion handler, which must be available before other drivers using it are loaded, which is why INTEL_SOC_PMIC is a bool. Just having the driver is not enough, the driver for the i2c-bus must also be built in, to ensure this, this patch adds a select for it. This fixes errors like these during boot: mmc0: SDHCI controller on ACPI [80860F14:00] using ADMA ACPI Error: No handler for Region [REGS] (ffff93543b0cc3a8) [UserDefinedRegion] (20170119/evregion-166) ACPI Error: Region UserDefinedRegion (ID=143) has no handler (20170119/exfldio-299) ACPI Error: Method parse/execution failed [\_SB.PCI0.I2C7.PMI5.GET] (Node ffff93543b0cde10), AE_NOT_EXIST (20170119/psparse-543) ACPI Error: Method parse/execution failed [\_SB.PCI0.SHC1._PS0] (Node ffff93543b0b5cd0), AE_NOT_EXIST (20170119/psparse-543) acpi 80860F14:02: Failed to change power state to D0 While at it this patch also changes the human readable name of the Kconfig option to make clear the INTEL_SOC_PMIC option selects support for the Intel Crystal Cove PMIC and documents why this is a bool.

Currently in WCOVE PMIC MFD driver, all second level IRQ chips are chained to the respective first level IRQs. So there is no need for explicitly unmasking the first level IRQ in this driver. This patches removes this level 1 IRQ unmask support. Signed-off-by:

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. Signed-off-by:

Currently all PMIC GPIO domain IRQs are consumed by the same device(bxt_wcove_gpio), so there is no need to export them as separate interrupts. We can just export only the first level GPIO IRQ(BXTWC_GPIO_LVL1_IRQ) as an IRQ resource and let the GPIO device driver(bxt_wcove_gpio) handle the GPIO sub domain IRQs based on status value of GPIO level2 interrupt status register. Also, just using only the first level IRQ will eliminate the bug involved in requesting only the second level IRQ and not explicitly enable the first level IRQ. For more info on this issue please read the details at, https://lkml.org/lkml/2017/2/27/148 This patch also makes relevant change in Whiskey cove GPIO driver to use only first level PMIC GPIO IRQ.

TMU interrupts are registered as a separate interrupt chip, and hence it should start its interrupt index(BXTWC_TMU_IRQ) number from 0. But currently, BXTWC_TMU_IRQ is defined as part of enum bxtwc_irqs_level2 and its index value is 11. Since this index value is used when calculating .num_irqs of regmap_irq_chip_tmu, it incorrectly reports number of IRQs as 12 instead of actual value of 1. This patch fixes this issue by creating new enum of tmu IRQs and resetting its starting index to 0. Signed-off-by:
