i2c: add dm_i2c_reg_clrset

2021-08-22T08:52:53+00:00

Add function to apply a bitmask to an i2c register, so that specific bits can be cleared and/or set. Suggested-by: Simon Glass Signed-off-by: Sebastian Reichel Reviewed-by: Simon Glass

i2c: Rename CONFIG_SYS_I2C to CONFIG_SYS_I2C_LEGACY

2021-07-28T18:29:37+00:00

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.

sandbox: i2c: Support i2c emulation with of-platdata

2021-03-26T04:03:08+00:00

At present the i2c emulators require access to the devicetree, which is not possible (by design) with of-platdata. Add a way for drivers to record the of-platdata index of their emulator, so that we can still find the emulator. This allows i2c emulation to work with of-platdata.

dm: i2c: use CONFIG_IS_ENABLED macro for DM_I2C/DM_I2C_GPIO

2021-02-21T05:08:00+00:00

Use CONFIG_IS_ENABLED() macro, which provides more convenient way to check $(SPL)DM_I2C/$(SPL)DM_I2C_GPIO configs for both SPL and U-Boot proper. CONFIG_IS_ENABLED(DM_I2C) expands to: - 1 if CONFIG_SPL_BUILD is undefined and CONFIG_DM_I2C is set to 'y', - 1 if CONFIG_SPL_BUILD is defined and CONFIG_SPL_DM_I2C is set to 'y', - 0 otherwise. All occurences were replaced automatically using these bash cmds: $ find . -type f -exec sed -i 's/ifndef CONFIG_DM_I2C/if !CONFIG_IS_ENABLED(DM_I2C)/g' {} + $ find . -type f -exec sed -i 's/ifdef CONFIG_DM_I2C/if CONFIG_IS_ENABLED(DM_I2C)/g' {} + $ find . -type f -exec sed -i 's/defined(CONFIG_DM_I2C)/CONFIG_IS_ENABLED(DM_I2C)/g' {} + $ find . -type f -exec sed -i 's/ifndef CONFIG_DM_I2C_GPIO/if !CONFIG_IS_ENABLED(DM_I2C_GPIO)/g' {} + $ find . -type f -exec sed -i 's/ifdef CONFIG_DM_I2C_GPIO/if CONFIG_IS_ENABLED(DM_I2C_GPIO)/g' {} + $ find . -type f -exec sed -i 's/defined(CONFIG_DM_I2C_GPIO)/CONFIG_IS_ENABLED(DM_I2C_GPIO)/g' {} + Reviewed-by: Heiko Schocher Reviewed-by: Simon Glass Signed-off-by: Igor Opaniuk Reviewed-by: Tom Rini Reviewed-by: Priyanka Jain

dm: treewide: Rename ofdata_to_platdata() to of_to_plat()

2020-12-13T23:51:09+00:00

This name is far too long. Rename it to remove the 'data' bits. This makes it consistent with the platdata->plat rename. Signed-off-by: Simon Glass

dm: treewide: Rename 'platdata' variables to just 'plat'

2020-12-13T23:51:08+00:00

We use 'priv' for private data but often use 'platdata' for platform data. We can't really use 'pdata' since that is ambiguous (it could mean private or platform data). Rename some of the latter variables to end with 'plat' for consistency. Signed-off-by: Simon Glass

i2c: Add a generic driver to generate ACPI info

2020-09-25T03:27:15+00:00

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

i2c: Export i2c_deblock_gpio_loop()

2020-03-16T06:46:04+00:00

Export the i2c_deblock_gpio_loop() so it can be used in other places in U-Boot. In particular, this is useful in the GPIO I2C driver, which claims the SDA/SCL GPIOs and thus prevents the i2c_deblock() implementation from claiming the pins as GPIOs again.
