2017-07-06mfd: Add LP87565 PMIC supportKeerthy5-0/+428
The LP87565 chip is a power management IC for Portable Navigation Systems and Tablet Computing devices. It contains the following components: - Configurable Bucks(Single and multi-phase). - Configurable General Purpose Output Signals (GPO). The LP87565-Q1 variant device uses two 2-phase outputs configuration, Buck0 is master for Buck0/1 output and Buck2 is master for Buck2/3 output.

2017-07-06mfd: axp20x-i2c: Document that this must be builtin on x86Hans de Goede1-0/+5
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: Hans de Goede <[email protected]> Acked-by: Chen-Yu Tsai <[email protected]> Tested-by: russianneuromancer <[email protected]> Signed-off-by: Lee Jones <[email protected]>
2017-07-06mfd: Add Cherry Trail Whiskey Cove PMIC driverHans de Goede3-0/+247
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 <[email protected]> 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.

2017-07-06mfd: intel_soc_pmic: Select designware i2c-bus driverHans de Goede1-2/+7
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.

This patch adds nvme_start_ctrl() which queues inflight controller works (aen, ns scan, queue start and keep-alive if kato is set) and nvme_stop_ctrl() which cancels the works namespace removal is left to the callers to handle.
