i2c-algo-bit: Generate correct i2c address sequence for 10-bit target

2011-12-09T16:54:04+00:00

commit cc6bcf7d2ec2234e7b41770185e4dc826390185e upstream.

The wrong bits were put on the wire, fix that.

This fixes kernel bug #42562.

i2c-algo-bit: Call pre/post_xfer for bit_test

2011-04-17T08:20:19+00:00

Apparently some distros set i2c-algo-bit.bit_test to 1 by
default.  In some cases this causes i2c_bit_add_bus
to fail and prevents the i2c bus from being added.  In the
radeon case, we fail to add the ddc i2c buses which prevents
the driver from being able to detect attached monitors.
The i2c bus works fine even if bit_test fails.  This is likely
due to gpio switching that is required and handled in the
pre/post_xfer hooks, so call the pre/post_xfer hooks in the
bit test as well.

i2c-algo-bit: Complain about masters which can't read SCL

2011-01-10T21:11:23+00:00

The I2C specification explicitly describes both SDA and SCL as
bidirectional lines. An I2C master with a read-only SCL is thus not
compliant. If a slow slave stretches the clock, errors will happen,
so the bus can't be considered as reliable.

i2c-algo-bit: Refactor adapter registration

2011-01-10T21:11:23+00:00

Use a function pointer to decide whether to call i2c_add_adapter or
i2c_add_numbered_adapter. This makes the code more compact than the
current strategy of having the common code in a separate function.

i2c: Fix Kconfig dependencies

2010-10-24T16:16:57+00:00

drivers/i2c/algos/Kconfig makes all the algorithms dependent on
!I2C_HELPER_AUTO, which triggers a Kconfig warning about broken
dependencies when some driver selects one of the algorithms. Ideally
we would make only the prompts dependent on !I2C_HELPER_AUTO, however
Kconfig doesn't currently support that. So we have to redefine the
symbols separately for the I2C_HELPER_AUTO=y case.

i2c-algo-pca: Fix coding style issues

2010-05-21T16:41:00+00:00

Fix up some coding style issues. i2c-algo-pca.c has been built
successfully after applying this patch and the binary object is
still exactly the same. Other issues found by checkpatch.pl were
voluntarily not fixed, either to keep readability, or because of
false positive errors.
