Some more general comments about what we are doing:
The i2c bus is a 2 wire serial bus, with clock (SCL) and data (SDA)

+ lines. To communicate on the bus (as a controller, we don't act as a target),
we first initiate a start condition (ivtv_start). We then write the
address of the device that we want to communicate with, along with a flag

an ACK signal (ivtv_ack), which tells us that it is ready for reading /
writing. We then proceed with reading or writing (ivtv_read/ivtv_write),

There is an additional form of transaction where a write may be
immediately followed by a read. In this case, there is no intervening

I2C v7, SMBus 3.2, and I3C 1.1.1 specifications have replaced "master/slave" with more appropriate terms. Inspired by and following on to Wolfram's series to fix drivers/i2c/[1], fix the terminology for users of I2C_ALGOBIT bitbanging interface, now that the approved verbiage exists in the specification. Compile tested, no functionality changes intended [1]: https://lore.kernel.org/all/20240322132619.6389-1-wsa+renesas@sang-engineering.com/ Signed-off-by: Easwar Hariharan <eahariha@linux.microsoft.com> --- drivers/media/pci/ivtv/ivtv-i2c.c | 20 ++++++++++---------- 1 file changed, 10 insertions(+), 10 deletions(-)
