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

dm: define LOG_CATEGORY for all uclass

2021-07-06T16:38:03+00:00

Define LOG_CATEGORY for all uclass to allow filtering with log command. Signed-off-by: Patrick Delaunay Reviewed-by: Simon Glass

dm: core: Use dev_has_ofnode() instead of dev_of_valid()

2021-01-05T19:24:41+00:00

We have two functions which do the same thing. Standardise on dev_has_ofnode() since there is no such thing as an 'invalid' ofnode in normal operation: it is either null or missing. Also move the functions into one place. Signed-off-by: Simon Glass Reviewed-by: Andy Shevchenko

i2c: Update for new sequence numbers

2020-12-19T03:32:21+00:00

Use the new sequence number in all cases. Drop the logic to check for a valid number in designware_i2c, since it will always be valid. Also drop the numbering in the uclass, since we can rely on driver model giving us the right sequence numbers. Signed-off-by: Simon Glass

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

dm: treewide: Rename auto_alloc_size members to be shorter

2020-12-13T15:00:25+00:00

This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. 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: Add log_ret() on error

2020-07-17T06:32:24+00:00

Add a few of these calls to make it easier to see where an error occurs, if CONFIG_LOG_ERROR_RETURN is enabled. Signed-off-by: Simon Glass Reviewed-by: Bin Meng Reviewed-by: Wolfgang Wallner Reviewed-by: Heiko Schocher

i2c: observe scl_count in i2c_deblock_gpio_loop()
