* mfd: sun6i-prcm: Allow to compile with COMPILE_TESTMaxime Ripard2019-04-031-1/+1
| | | | | | | | | Since this driver only has a dependency on ARCH_SUNXI just because it doesn't make any sense to run it on something else, we can definitely enable it through COMPILE_TEST as well to get some build coverage.

| * dma-mapping: improve selection of dma_declare_coherent availabilityChristoph Hellwig2019-02-201-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | This API is primarily used through DT entries, but two architectures and two drivers call it directly. So instead of selecting the config symbol for random architectures pull it in implicitly for the actual users. Also rename the Kconfig option to describe the feature better.

| * mfd/sm501: depend on HAS_DMAChristoph Hellwig2019-02-131-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | Currently the sm501 mfd driver can be compiled without any dependencies, but through the use of dma_declare_coherent it really depends on having DMA and iomem support. Normally we don't explicitly require DMA support as we have stubs for it if on UML, but in this case the driver selects support for dma_declare_coherent and thus also requires memmap support. Guard this by an explicit dependency. Signed-off-by: Christoph Hellwig <hch@lst.de> Acked-by: Lee Jones <lee.jones@linaro.org>

This rework, in a classic fall-between-the-chairs fashion has been sidestepped for too long. The Qualcomm IRQchips using the SPMI and SSBI transport mechanisms have been rewritten to use hierarchical irqchip. This creates the base from which I intend to gradually pull support for hierarchical irqchips into the gpiolib irqchip helpers to cut down on duplicate code. We have too many hacks in the kernel because people have been working around the missing hierarchical irqchip for years, and once it was there, noone understood it for a while. We are now slowly adapting to using it. This is why this pull requests include changes to MFD, SPMI, IRQchip core and some ARM Device Trees pertaining to the Qualcomm chip family. Since Qualcomm have so many chips and such large deployments it is paramount that this platform gets this right, and now it (hopefully) does. - Core support for pull-up and pull-down configuration, also from the device tree. When a simple GPIO chip supports an "off or on" pull-up or pull-down resistor, we provide a way to set this up using machine descriptors or device tree. If more elaborate control of pull up/down (such as resistance shunt setting) is required, drivers should be phased over to use pin control. We do not yet provide a userspace ABI for this pull up-down setting but I suspect the makers are going to ask for it soon enough. PCA953x is the first user of this new API. - The GPIO mockup driver has been revamped after some discussion improving the IRQ simulator in the process. The idea is to make it possible to use the mockup for both testing and virtual prototyping, e.g. when you do not yet have a GPIO expander to play with but really want to get something to develop code around before hardware is available. It's neat. The blackbox testing usecase is currently making its way into kernelci. - ACPI GPIO core preserves non direction flags when updating flags. - A new device core helper for devm_platform_ioremap_resource() is funneled through the GPIO tree with Greg's ACK. New drivers: - TQ-Systems QTMX86 GPIO controllers (using port-mapped I/O) - Gateworks PLD GPIO driver (vaccumed up from OpenWrt) - AMD G-Series PCH (Platform Controller Hub) GPIO driver. - Fintek F81804 & F81966 subvariants. - PCA953x now supports NXP PCAL6416. Driver improvements: - IRQ support on the Nintendo Wii (Hollywood) GPIO. - get_direction() support for the MVEBU driver. - Set the right output level on SAMA5D2. - Drop the unused irq trigger setting on the Spreadtrum driver. - Wakeup support for PCA953x. - A slew of cleanups in the various Intel drivers" * tag 'gpio-v5.1-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (110 commits) gpio: gpio-omap: fix level interrupt idling gpio: amd-fch: Set proper output level for direction_output x86: apuv2: remove unused variable gpio: pca953x: Use PCA_LATCH_INT platform/x86: fix PCENGINES_APU2 Kconfig warning gpio: pca953x: Fix dereference of irq data in shutdown gpio: amd-fch: Fix type error found by sparse gpio: amd-fch: Drop const from resource gpio: mxc: add check to return defer probe if clock tree NOT ready gpio: ftgpio: Register per-instance irqchip gpio: ixp4xx: Add DT bindings x86: pcengines apuv2 gpio/leds/keys platform driver gpio: AMD G-Series PCH gpio driver drivers: depend on HAS_IOMEM for devm_platform_ioremap_resource() gpio: tqmx86: Set proper output level for direction_output gpio: sprd: Change to use SoC compatible string gpio: sprd: Use SoC compatible string instead of wildcard string gpio: of: Handle both enable-gpio{,s} gpio: of: Restrict enable-gpio quirk to regulator-gpio gpio: davinci: use devm_platform_ioremap_resource() ...

It allows the connection of most Cirrus Logic devices on mini-cards, as well as allowing connection of various application processor systems to provide a full evaluation platform. This driver supports the board controller chip on the Lochnagar board. Audio system topology, clocking and power can all be controlled through the Lochnagar controller chip, allowing the device under test to be used in a variety of possible use cases. As the Lochnagar is a fairly complex device this MFD driver allows the drivers for the various features to be bound in. Initially clocking, regulator and pinctrl will be added as these are necessary to configure the system. But in time at least audio and voltage/current monitoring will also be added.

| | | | | | | | | | | | | | | | | | | | | Both Bay and Cherry Trail devices may be used together with a Crystal Cove PMIC. Each platform has its own variant of the PMIC, which both use the same ACPI HID, but they are not 100% compatible. This commits makes the intel_soc_pmic_core code check the _HRV of the ACPI-firmware-node and selects intel_soc_pmic_config_byt_crc resp. intel_soc_pmic_config_cht_crc based on this. This fixes the Bay Trail specific ACPI OpRegion code causing problems on Cherry Trail devices. Specifically this was causing the external microsd slot on a Dell Venue 8 5855 (Cherry Trail version) to not work and the eMMC to become unreliable and throw lots of errors.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
