gpio: i2c-gpio: Drop use of dm_gpio_set_dir()

2021-04-12T21:45:40Z

This is the only driver that uses this function. Update it to use the alternative which is dm_gpio_clrset_flags(). Signed-off-by: Simon Glass Tested-by: Harm Berntsen

sandbox: i2c: Support i2c emulation with of-platdata

2021-03-26T04:03:08Z

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.

sandbox: i2c: Move platdata structs to header files

2021-03-26T04:03:08Z

At present the structs used by these drivers are declared in the C files and so are not accessible to dtoc. Move them to header files, as required. Signed-off-by: Simon Glass Signed-off-by: Simon Glass

sandbox: i2c: Rename driver names to work with of-platdata

2021-03-22T06:23:27Z

Some of these do not follow the rules. Make sure the driver name matches the compatible string in all cases. Signed-off-by: Simon Glass

dm: i2c: use CONFIG_IS_ENABLED macro for DM_I2C/DM_I2C_GPIO

2021-02-21T05:08:00Z

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: 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
