These symbols have to be added manually to the Kconfig files. Kconfig.host and hw/Kconfig were created manually.

Kconfig: Add I2C_DEVICES device group Currently there is no way for a board model's Kconfig stanza to say "I have an i2c bus which the user can plug an i2c device into, build all the free-standing i2c devices". The Kconfig mechanism for this is the "device group". Add an I2C_DEVICES group along the same lines as the existing PCI_DEVICES. Simple free-standing i2c devices which a user might plausibly want to be able to plug in on the QEMU commandline should have default y if I2C_DEVICES and board models which have an i2c bus that is user-accessible should use imply I2C_DEVICES to cause those pluggable devices to be built. In this commit we mark only a fairly conservative set of i2c devices as belonging to the I2C_DEVICES group: the simple sensors and RTCs (not including PMBus devices or devices which need GPIO lines to be connected).

PPC: E500: Add FSL I2C controller and integrate RTC with it Original commit message: This patch adds an emulation model for i2c controller found on most of the FSL SoCs. It also integrates the RTC (ds1338) that sits on the i2c Bus with e500 machine model. Patch was originally written by Amit Singh Tomar <amit.tomar@freescale.com> see http://patchwork.ozlabs.org/patch/431475/ I only fixed it enough for application on top of current qemu master 20b084c4b1401b7f8fbc385649d48c67b6f43d44, and hopefully fixed checkpatch errors Tested by booting Linux kernel 4.20.12. Now e500 machine doesn't need network time protocol daemon because it will have working RTC (before all timestamps on files were from 2016) Signed-off-by: Amit Singh Tomar <amit.tomar@freescale.com> Signed-off-by: Andrew Randrianasulu <randrianasulu@gmail.com> Message-Id: <20190306102812.28972-1-randrianasulu@gmail.com> [dwg: Add Kconfig stanza to define the new symbol, update MAINTAINERS] Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

{hw/i2c,docs/system/arm}: Allwinner TWI/I2C Emulation This patch implements Allwinner TWI/I2C controller emulation. Only master-mode functionality is implemented. The SPL boot for Cubieboard expects AXP209 PMIC on TWI0/I2C0 bus, so this is first part enabling the TWI/I2C bus operation. Since both Allwinner A10 and H3 use the same module, it is added for both boards. Docs are also updated for Cubieboard and Orangepi-PC board to indicate I2C availability.
