From b5bf5a53d1e02eb0c7fdc6271e10ebd0eda79813 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Tue, 8 Feb 2022 15:59:10 +0000 Subject: Kconfig: Add I2C_DEVICES device group MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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).
