Start changing the wording of the I2C main header wrt. the newest I2C v7, SMBus 3.2, I3C specifications and replace "master/slave" with more appropriate terms. The first step renames the members of struct i2c_algorithm. Once all in-tree users are converted, the anonymous union will go away again. All this work will also pave the way for finally seperating the monolithic header into more fine-grained headers like "i2c/clients.h" etc. Signed-off-by: Wolfram Sang <wsa+renesas@sang-engineering.com> --- include/linux/i2c.h | 24 +++++++++++++++++++----- 1 file changed, 19 insertions(+), 5 deletions(-)
