2023-08-02i2c: designware: Add Kconfig for designware_i2c_pci.cMinda Chen1-0/+9
As the Designware_i2c_pci.c uses ACPI APIs, If some SoCs (StarFive JH7110) contain Designware i2c and PCI but do not use ACPI, This file cannot be compiled.

2021-10-12i2c: Add a DM_I2C driver for the sun8i RSB controllerSamuel Holland1-0/+8
This bus controller is used to communicate with an X-Powers AXP PMIC. Currently, various drivers access PMIC registers through a platform- specific non-DM "pmic_bus" interface, which depends on the legacy I2C framework. In order to convert those drivers to use DM_PMIC, this bus needs a DM_I2C driver. Refactor the rsb functions to take the base address as a parameter, and implement both the existing interface (which is still needed in SPL) and the DM_I2C interface on top of them. The register for switching between I2C/P2WI/RSB mode is the same across all PMIC variants, so move that to the common header. There are only a couple of pairs of hardware/runtime addresses used across all PMIC variants. So far the code expected only the "primary" pair, but some PMICs like the AXP305 and AXP805 use the secondary pair, so add support for that to the DM driver as well.

2021-07-28i2c: Create a new Kconfig for I2CSimon Glass1-2/+24
At present we have CONFIG_SPL_I2C but not CONFIG_I2C. The reason CONFIG_I2C is not strictly necessary is that: a) We have CONFIG_SYS_I2C_LEGACY and CONFIG_DM_I2C for the two possible i2c stacks b) In U-Boot proper, we always build drivers/i2c/ regardless of the options Still, it is better to have CONFIG_I2C - it makes U-Boot proper similar to SPL/TPL, so we can (in a future commit) simplify the Makefile rules. Enable it by default, since as above, we have separate options (SYS_I2C_LEGACY and DM_I2C) to control whether it is 'really' enabled. Once we have migrated I2C to driver model, we can drop SYS_I2C_LEGACY and make DM_I2C become I2C. For now, this lets us simplify the Makefile rules.

2021-02-21dm: i2c: allow disabling driver model in SPLIgor Opaniuk1-0/+21
At present if U-Boot proper uses driver model for I2C, then SPL has to also. While this is desirable, it places a significant barrier to moving to driver model in some cases. For example, with a space-constrained SPL it may be necessary to enable CONFIG_SPL_OF_PLATDATA which involves adjusting some drivers. This patch introduces a separate Kconfig symbols for enabling DM_I2C and DM_I2C_GPIO support in SPL. This will also help to get away from dirty workarounds to achieve non-DM I2C support for SPL, which is currently used in some board header files like: ifdef CONFIG_SPL_BUILD undef CONFIG_DM_I2C endif Reviewed-by: Simon Glass <sjg@chromium.org> Reviewed-by: Heiko Schocher <hs@denx.de> Signed-off-by: Igor Opaniuk <igor.opaniuk@foundries.io> Reviewed-by: Tom Rini <trini@konsulko.com>

These options only apply when not using DM_I2C. When using device trees, the dt will enable and control the speeds of the I2C controller(s) and these configuration options have no effect. So disable them in DM_I2C mode. Otherwise they show up as decoys, and make it look like one is enabling I2C controllers and setting the speed when really it's doing nothing. However, a system using a SPL build will not use DM_I2C in the SPL, even if DM_I2C is enabled for the main u-boot. And so the SPL might use the kconfig based I2C speed controls while the main u-boot does not.
