Mgag200's .get_modes() function is identical to the common helper.
Use the latter.

Compute the i2c timeout in jiffies from a value in milliseconds. The
original values of 2 jiffies equals 2 milliseconds if HZ has been
configured to a value of 1000. This corresponds to 2.2 milliseconds
used by most other DRM drivers. Update mgag200 accordingly.

The function mgag200_i2c_init() is an internal helper that sets
up the i2c data structure. Inline its code into the only caller.
Rearrange the individual steps to separate among i2c algorithm,
adapter and fields in struct mga_i2c_chan.

Managed cleanup with devm_add_action_or_reset() will release the I2C
adapter when the underlying Linux device goes away. But the connector
still refers to it, so this cleanup leaves behind a stale pointer
in struct drm_connector.ddc.
Bind the lifetime of the I2C adapter to the connector's lifetime
Clean up a the driver's DDC code, make it simpler, more robust, and
mostly self contained. The patches in this patchset have previously
been sent as part of rev 1 of [1].
Patches 1 and 2 fix long-standing problems in the DDC code.
Patches 3 to 9 refactor the DDC code. The code then keeps its data
The modeset lock protects the DDC code from concurrent modeset
operations, which use the same registers. Move that code from the
connector helpers into the DDC helpers .pre_xfer() and .post_xfer().
Both, .pre_xfer() and .post_xfer(), enclose the transfer of data blocks
over the I2C channel in the
Align the names of the algo-bit helpers with mgag200's convention of

Rename struct mga_i2c_chan to struct mgag200_ddc, define it in the
source file mgag200_i2c.c, and reorder its fields. Rename all related
variables from i2c to ddc. Also rename the i2c adapter accordingly.
Using the term 'ddc' documents the purpose of the code clearly. The
old term 'i2c' could refe
Allocate instances of struct mga_i2c_chan in mgag200_ddc_create()

the function are now independent from struct mga_i2c_chan.
