i2c: Add I2C_AQ_NO_REP_START adapter quirk

2021-05-19T08:08:22Z

[ Upstream commit aca01415e076aa96cca0f801f4420ee5c10c660d ] This quirk signifies that the adapter cannot do a repeated START, it always issues a STOP condition after transfers. Suggested-by: Wolfram Sang Signed-off-by: Bence Csókás Signed-off-by: Wolfram Sang Signed-off-by: Sasha Levin

i2c: replace i2c_new_secondary_device with an ERR_PTR variant

2019-08-14T12:54:55Z

In the general move to have i2c_new_*_device functions which return ERR_PTR instead of NULL, this patch converts i2c_new_secondary_device(). There are only few users, so this patch converts the I2C core and all users in one go. The function gets renamed to i2c_new_ancillary_device() so out-of-tree users will get a build failure to understand they need to adapt their error checking code.

i2c: add newly exported functions to the header, too

2019-06-26T13:10:35Z

Nobody (including me) noticed that these functions were exported but not added to the header :/ Fixes: 7159dbdae3c5 ("i2c: core: improve return value handling of i2c_new_device and i2c_new_dummy") Signed-off-by: Wolfram Sang Reviewed-by: Bartosz Golaszewski Reviewed-by: Kieran Bingham Signed-off-by: Wolfram Sang

i2c: headers: update docs about I2C_CLIENT_*

Update kerneldoc for i2c client flags because they increased over time. Also, move them to a position where they can be more easily found. Signed-off-by: Wolfram Sang

i2c: headers: always have a named variable in arguments

2019-06-14T21:24:33Z

Much better to read and understand. Naming for i2c_adapter is not consistent (yet), so use the name which is also used in core code. Signed-off-by: Wolfram Sang

i2c: headers: don't use 'dev' as adapter variable

2019-06-14T21:24:33Z

It is not a struct device, so 'dev' is confusing. Use 'adap', the most common name. Signed-off-by: Wolfram Sang

i2c: acpi: export i2c_acpi_find_adapter_by_handle
