i2c: designware_i2c: Correct the selection of speed mode

2020-02-18T07:16:45+00:00

Unfortunately a recent change adjusted the order of the checks here such
that 400MHz now shows up as fast-plus speed (1Mbps). Fix it.

tegra: i2c: Change driver to use helper function

2020-02-07T14:41:24+00:00

Now that we have uclass_first_device_drvdata(), use it from the I2C driver
to reduce code duplication.

dm: core: Create a new header file for 'compat' features

2020-02-06T02:33:46+00:00

At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.

Move the compatibility features into a separate header file.

dm: core: Require users of devres to include the header

2020-02-06T02:33:46+00:00

At present devres.h is included in all files that include dm.h but few
make use of it. Also this pulls in linux/compat which adds several more
headers. Drop the automatic inclusion and require files to include devres
themselves. This provides a good indication of which files use devres.

i2c: designware_i2c: Do more in the probe() method

2020-01-27T06:25:00+00:00

Move some of the code currently in the ofdata_to_platdata() method to
probe() so that it is not executed when generating ACPI tables.

i2c: designware_i2c: Separate out the speed calculation

2020-01-27T06:24:44+00:00

We want to be able to calculate the speed separately from actually setting
the speed, so we can generate the required ACPI tables. Split out the
calculation into its own function.

Drop the double underscore on __dw_i2c_set_bus_speed while we are here.
That is reserved for compiler internals.

i2c: designware_i2c: Move dw_i2c_speed_config to header

2020-01-27T06:24:29+00:00

This is used to store the speed information for a bus. We want to provide
this to ACPI so that it can tell the kernel. Move this struct to the
header file so it can be accessed by the ACPI i2c implementation being
added later.

i2c: designware_i2c: Add support for fast-plus speed

Fast-plus runs at 1MHz and is used by some devices. Add support for this.
