2017-09-05mfd: t7l66xb: Handle return value of clk_prepare_enableArvind Yadav1-3/+14
clk_prepare_enable() can fail here and we must check its return value. we must disable clock, if t7l66xb_probe is not successful. Signed-off-by: Arvind Yadav <arvind.yadav.cs@gmail.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2017-09-05mfd: intel_soc_pmic_chtwc: Turn Kconfig option into a boolHans de Goede1-1/+1
The PMIC provides ACPI OpRegions which must be available for other drivers' PS0 / PS3 methods early-on as such it must be builtin as the Kconfig help text already states. Somehow its Kconfig option ended up being a tristate though, this fixes this. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>

2017-09-05mfd: Add support for TPS68470 deviceRajmohan Mani3-0/+125
The TPS68470 device is an advanced power management unit that powers a Compact Camera Module (CCM), generates clocks for image sensors, drives a dual LED for Flash and incorporates two LED drivers for general purpose indicators.

2017-09-05mfd: lpc_ich: Do not touch SPI-NOR write protection bit on Haswell/BroadwellMika Westerberg1-10/+0
At least on Lenovo Thinkpad Yoga, the BIOS seems to monitor the SPI-NOR write protection bit and if it is flipped to read/write it assumes the BIOS configuration was changed on next reboot. It then, for unknown reasons, resets the BIOS settings back to default. We can prevent this by just leaving the write protection bit intact and let the SPI-NOR driver know whether the device is writable or not. In case of this particular Lenovo the SPI-NOR flash will be exposed as read-only.

According to their datasheets, the AXP221, AXP223, AXP288, AXP803, AXP809 and AXP813 PEK have different values for startup time bits from the AXP20X, let's use the platform device id with the correct values.

2017-09-05mfd: axp20x: Add support for AXP813 PMICChen-Yu Tsai2-0/+23
The X-Powers AXP813 PMIC is normally used with Allwinner's A83T SoC. It has the same range of functions as other X-Powers PMICs, such as DC-DC buck converter and linear regulator outputs, AC-IN and VBUS power supplies, power button trigger, GPIOs, ADCs, and a battery charger. Note that the IRQ table given in the datasheet is incorrect: in IRQ enable/status registers 1, there are separate IRQs for ACIN and VBUS, instead of bits [7:5] being the same as bits [4:2]. So it shares the same IRQs as the AXP803, rather than the AXP288. This patch adds basic mfd support for it, with only the power button enabled.

Drop static on a local variable, when the variable is initialized before any use, on every possible execution path through the function. The static has no benefit, and dropping it reduces the code size.

2017-07-06mfd: Add LP87565 PMIC supportKeerthy3-0/+115
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.

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.

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 <hdegoede@redhat.com> Acked-by: Chen-Yu Tsai <wens@csie.org> Tested-by: russianneuromancer <russianneuromancer@ya.ru> Signed-off-by: Lee Jones <lee.jones@linaro.org>
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 <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.
