Having a separate Kconfig option for i2c-smbus makes it possible to build that support as a module even when i2c-core itself is built-in. Bus drivers which implement SMBus alert should select this option, so in most cases this option is hidden and the user doesn't have to care about it.

i2c: Let users select algorithm drivers manually again
In kernel 2.6.26, the ability to select I2C algorithm drivers manually was removed, as all in-kernel drivers do that automatically. However there were some complaints that it was a problem for out-of-tree I2C bus drivers. In order to address these complaints, let's allow manual selection of these drivers again, but still hide them by default for better general user experience.
This closes bug #11140: http://bugzilla.kernel.org/show_bug.cgi?id=11140

i2c: Add i2c_board_info and i2c_new_device()
This provides partial support for new-style I2C driver binding. It builds on "struct i2c_board_info" declarations that identify I2C devices on a given board. This is needed on systems with I2C devices that can't be fully probed and/or autoconfigured, such as many embedded Linux configurations where the way a given I2C device is wired may affect how it must be used.
There are two models for declaring such devices:
* LATE -- using a public function i2c_new_device(). This lets modules declare I2C devices found *AFTER* a given I2C adapter becomes available. For example, a PCI card could create adapters giving access to utility chips on that card, and this would be used to associate those chips with those adapters.
* EARLY -- from arch_initcall() level code, using a non-exported function i2c_register_board_info(). This copies the declarations *BEFORE* such an i2c_adapter becomes available, arranging that i2c_new_device() will be called later when i2c-core registers the relevant i2c_adapter.
For example, arch/.../.../board-*.c files would declare the I2C devices along with their platform data, and I2C devices would behave much like PNPACPI devices. (That is, both enumerate from board-specific tables.)
To match the exported i2c_new_device(), the previously-private function i2c_unregister_device() is now exported.
Pending later patches using these new APIs, this is effectively a NOP.

We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.

Usually, you need specific devices to test e.g. SMBus Host Notify and such. With this driver you just need the slave interface of another I2C controller. This initial version has testcases for multi-master and SMBus Host Notify. Already planned but not yet implemented are SMBus Alert and messages with I2C_M_RECV_LEN.

treewide: replace '---help---' in Kconfig files with 'help' Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

treewide: surround Kconfig file paths with double quotes The Kconfig lexer supports special characters such as '.' and '/' in the parameter context. In my understanding, the reason is just to support bare file paths in the source statement. I do not see a good reason to complicate Kconfig for the room of ambiguity. The majority of code already surrounds file paths with double quotes, and it makes sense since file paths are constant string literals. Make it treewide consistent now.

Merge branch 'i2c/for-4.10' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux Pull i2c updates from Wolfram Sang: - the first series of making i2c_device_id optional instead of mandatory (in favor of alternatives like of_device_id). This involves adding a new probe callback (probe_new) which removes some peculiarities I2C had for a long time now. The new probe is matching the other subsystems now and the old one will be removed once all users are converted. It is expected to take a while but there is ongoing interest in that. - SMBus Host Notify introduced 4.9 got refactored. They are now using interrupts instead of the alert callback which solves multiple issues. - new drivers for iMX LowPower I2C, Mellanox CPLD and its I2C mux - significant refactoring for bcm2835 driver - the usual set of driver updates and improvements * 'i2c/for-4.10' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (46 commits) i2c: fsl-lpi2c: read lpi2c fifo size in probe() i2c: octeon: thunderx: Remove double-check after interrupt i2c: octeon: thunderx: TWSI software reset in recovery i2c: cadence: Allow Cadence I2C to be selected for Cadence Xtensa CPUs i2c: sh_mobile: Add per-Generation fallback bindings i2c: rcar: Add per-Generation fallback bindings i2c: imx-lpi2c: add low power i2c bus driver dt-bindings: i2c: imx-lpi2c: add devicetree bindings i2c: designware-pcidrv: Add 10bit address feature to medfield/merrifield i2c: pxa: Add support for the I2C units found in Armada 3700 i2c: pxa: Add definition of fast and high speed modes via the regs layout dt-bindings: i2c: pxa: Update the documentation for the Armada 3700 i2c: qup: support SMBus block read i2c: qup: add ACPI support i2c: designware: Consolidate default functionality bits i2c: i2c-mux-gpio: update mux with gpiod_set_array_value_cansleep i2c: mux: pca954x: Add ACPI support for pca954x i2c: use an IRQ to report Host Notify events, not alert i2c: i801: remove SMBNTFDDAT reads as they always seem to return 0 i2c: i801: use the BIT() macro for FEATURES_* also ...

i2c: use an IRQ to report Host Notify events, not alert The current SMBus Host Notify implementation relies on .alert() to relay its notifications. However, the use cases where SMBus Host Notify is needed currently is to signal data ready on touchpads. This is closer to an IRQ than a custom API through .alert(). Given that the 2 touchpad manufacturers (Synaptics and Elan) that use SMBus Host Notify don't put any data in the SMBus payload, the concept actually matches one to one. Benefits are multiple: - simpler code and API: the client will just have an IRQ, and nothing needs to be added in the adapter beside internally enabling it. - no more specific workqueue, the threading is handled by IRQ core directly (when required) - no more races when removing the device (the drivers are already required to disable irq on remove) - simpler handling for drivers: use plain regular IRQs - no more dependency on i2c-smbus for i2c-i801 (and any other adapter) - the IRQ domain is created automatically when the adapter exports the Host Notify capability - the IRQ are assign only if ACPI, OF and the caller did not assign one already - the domain is automatically destroyed on remove - fewer lines of code (minus 20, yeah!)

i2c: mux: fix up dependencies We get the following build error from UM Linux after adding an entry to drivers/iio/gyro/Kconfig that issues "select I2C_MUX": ERROR: "devm_ioremap_resource" [drivers/i2c/muxes/i2c-mux-reg.ko] undefined! ERROR: "of_address_to_resource" [drivers/i2c/muxes/i2c-mux-reg.ko] undefined! It appears that the I2C mux core code depends on HAS_IOMEM for historical reasons, while CONFIG_I2C_MUX_REG does *not* have a direct dependency on HAS_IOMEM. This creates a situation where a allyesconfig or allmodconfig for UM Linux will select I2C_MUX, and will implicitly enable I2C_MUX_REG as well, and the compilation will fail for the register driver. Fix this up by making I2C_MUX_REG depend on HAS_IOMEM and removing the dependency from I2C_MUX.
