pci: Drop DM_PCI

This option has not effect now. Drop it, using PCI instead where needed. Signed-off-by: Simon Glass

i2c: Rename CONFIG_SYS_I2C to CONFIG_SYS_I2C_LEGACY

2021-07-28T18:29:37Z

It is quite confusing that CONFIG_SYS_I2C selects the legacy I2C and CONFIG_DM_I2C selects the current I2C. The deadline to migrate I2C is less than a year away. Also we want to have a CONFIG_I2C for U-Boot proper just like we have CONFIG_SPL_I2C for SPL, so we can simplify the Makefile rules. Rename this symbol so it is clear it is going away.

dm: i2c: allow disabling driver model in SPL

2021-02-21T05:07:30Z

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 Reviewed-by: Heiko Schocher Signed-off-by: Igor Opaniuk Reviewed-by: Tom Rini

sandbox: Disable I2C emulators in SPL

2021-01-30T21:25:41Z

These cannot work with of-platdata since they currently need the devicetree at runtime. Disable the emulators and the sandbox I2C driver that needs them. We can enable these later, if needed for testing. Switch the of_plat_parent test over to use a simple bus instead. Signed-off-by: Simon Glass Reviewed-by: Heiko Schocher

i2c: ocores: add i2c driver for OpenCores I2C controller

2020-11-28T07:30:41Z

Add support for the OpenCores I2C controller IP core (See http://www.opencores.org/projects.cgi/web/i2c/overview). This driver implementation is inspired from the Linux OpenCores I2C driver available. Thanks to Peter Korsgaard for writing Linux OpenCores I2C driver.

sandbox: Fix up building for of-platdata

2020-10-29T20:42:18Z

There is no devicetree with of-platdata. Update a few uclasses to allow them to be built for sandbox_spl. Also drop the i2c-gpio from SPL to avoid build errors, since it does not support of-platdata. Signed-off-by: Simon Glass

i2c: Add a generic driver to generate ACPI info

2020-09-25T03:27:15Z

Many I2C devices produce roughly the same ACPI data with just things like the GPIO/interrupt information being different. This can be handled by a generic driver along with some information in the device tree. Add a generic i2c driver for this purpose. Signed-off-by: Simon Glass Reviewed-by: Heiko Schocher

Link failure with CONFIG_SPL and CONFIG_I2C_MUX_PCA954x

2020-08-25T04:25:42Z

Fix for the case of a U-Boot configuration with CONFIG_SPL, CONFIG_I2C_MUX, CONFIG_I2C_MUX_PCA954x, no CONFIG_SPL_DM and no CONFIG_SPL_I2C_MUX. Without this fix linking of pca954x fails because dm_write_i2c does not exist because CONFIG_SPL_DM is not defined. Signed-off-by: Kees Trommel Cc: Heiko Schocher
