This patch implements the USB part of the Diolan USB-I2C/SPI/GPIO Master Adapter DLN-2. Details about the device can be found here: https://www.diolan.com/i2c/i2c_interface.html. Information about the USB protocol can be found in the Programmer's Reference Manual [1], see section 1.7. Because the hardware has a single transmit endpoint and a single receive endpoint the communication between the various DLN2 drivers and the hardware will be muxed/demuxed by this driver. Each DLN2 module will be identified by the handle field within the DLN2 message header. If a DLN2 module issues multiple commands in parallel they will be identified by the echo counter field in the message header. The DLN2 modules can use the dln2_transfer() function to issue a command and wait for its response. They can also register a callback that is going to be called when a specific event id is generated by the device (e.g. GPIO interrupts). The device uses handle 0 for sending events.

The UCB1200 / UCB1300 driver uses the MCP_SA11X0 driver, which can be a loadable module, but this results in a link error when UCB1200 itself is built-in: drivers/built-in.o: In function `ucb1x00_io_set_dir': :(.text+0x4a364): undefined reference to `mcp_reg_write' drivers/built-in.o: In function `ucb1x00_io_write': :(.text+0x4a3dc): undefined reference to `mcp_reg_write' drivers/built-in.o: In function `ucb1x00_io_read': :(.text+0x4a400): undefined reference to `mcp_reg_read' drivers/built-in.o: In function `ucb1x00_adc_enable': :(.text+0x4a460): undefined reference to `mcp_enable' ... This can easily be resolved by making CONFIG_MCP_UCB1200 itself a tristate option, since that causes Kconfig to track the dependency correctly.

The versatile express changes for 3.16 introduced a number of build regressions for randconfig kernels by not tracking dependencies between the components right. This patch tries to rectify that: * the mach-vexpress code cannot link without the syscfg driver, which in turn needs MFD_VEXPRESS_SYSREG * various drivers call devm_regmap_init_vexpress_config(), which has to be exported so it can be used by loadable modules * the configuration bus uses OF DT helper functions that are not available to platforms disable CONFIG_OF * The sysreg driver exports GPIOs through gpiolib, which can be disabled on some platforms. * The clocksource code cannot be built on platforms that don't use modern timekeeping but rely on gettimeoffset.

This patch - finally, after over 6 months! :-( - addresses Samuel's request to split the vexpress-sysreg driver into smaller portions and define the device in a form of MFD cells: * LEDs code has been completely removed and replaced with "gpio-leds" nodes in the tree (referencing dedicated GPIO subnodes in sysreg - bindings documentation updated); this also better fits the reality as some variants of the motherboard don't have all the LEDs populated * syscfg bridge code has been extracted into a separate driver (placed in drivers/misc for no better place) * all the ID & MISC registers are defined as sysconf making them available for other drivers should they need to use them (and also to the user via /sys/kernel/debug/regmap which can be helpful in platform debugging) Signed-off-by: NPawel Moll <pawel.moll@arm.com> Acked-by: NLee Jones <lee.jones@linaro.org>

Add Maxim 77836 support to max14577 driver. The chipsets have same MUIC component so the extcon, charger and regulators are almost the same. The MAX77836 however has also PMIC and Fuel Gauge. The MAX77836 uses three I2C slave addresses and has additional interrupts (related to PMIC and Fuel Gauge). It has also Interrupt Source register, just like MAX77686 and MAX77693. The MAX77836 PMIC's TOPSYS and INTSRC interrupts are reported in the PMIC block. The PMIC block has different I2C slave address and uses own regmap so another regmap_irq_chip is needed. Since we have two regmap_irq_chip, use shared interrupts on MAX77836. This patch adds additional defines and functions to the max14577 MFD core driver so the driver will handle both chipsets. Also this patch replaces "0x1 << N" with BIT(N) in defines for register masks.

The pm8xxx-irq.c code is practically mandatory given that the pm8921-core driver will WARN about it missing and the Kconfig marks it as default y when a PM8xxx chips is enabled. The only reason the file was split out was because we planned to support other pm8xxx chips with different pm8xxx-core.c files. Now that we have DT on ARM this isn't necessary because we should be able to support all the ssbi based PM8xxx chips in one driver and one file with no data bloat. Let's move this code into the only driver that uses it right now (pm8921) so that it's always compiled when needed. In the future we can rename pm8921-core.c to something more generic.
