[PATCH v2 0/2] OMAP: I2C and UART device name cleanup

[PATCH v2 0/2] OMAP: I2C and UART device name cleanup

[Benoit Cousson]

Hi All,

In order to enforce a little bit of consistency in the omap devices name,
the convention for omap devices name will be now omap_xxx. All the drivers
adapted to hwmod will be named like that during the on-going adaptations.

The I2C and UART drivers are already adapted to hwmod but with
the originals name.

Rename i2c and uart using this convention:
i2c_omap -> omap_i2c
omap-hsuart -> omap_uart

Tested on OMAP4 ES2 on Panda / sdp4430. Some more validation will be needed on OMAP2 & 3.

This series is based on Kevin's pm-hwmod-i2c branch and is available here:
git://gitorious.org/omap-pm/linux.git for_2.6.38/device_name

Regards,
Benoit


v1
    http://www.spinics.net/lists/linux-omap/msg41474.html
    
    Merge previous patch #1 and #2 as suggested by Kevin to change the driver name 
    at the same time with the device name in the clockdev.


Benoit Cousson (2):
  I2C: i2c-omap: Change device name: i2c_omap -> omap_i2c
  OMAP: serial: Change device name: omap-hsuart -> omap_uart

[PATCH v2 1/2] I2C: i2c-omap: Change device name: i2c_omap -> omap_i2c

[Benoit Cousson]

The convention for omap device naming is omap_XXX.

Rename the device and driver name in order to stick
to this naming convention.

Change device name in clock nodes as well.

With your ack for the name change in the driver, we can merge this
through the OMAP tree with the other core changes.

Renaming stuff like this is going to have an impact on the userspace
as anyone looking through /sys's driver heirarchy is going to miss the
old name... 

It all depends if you really want to go ahead with this...

Yes, we are aware of the userspace impact, but this name change makes
all devices on OMAP have consistent names and actually improves the
ability to have userspace tools have consistent naming as well.

So there are no imporant users, or if there is, they are prepared for this change?

What about the .c / .ko file name?

Pretty much everyone is in the form of i2c-xxx.c, so I would prefer it
to stay that way.

Pretty much everything in the drivers/i2c/busses directory is named
i2c-<something>.c, and I would like to keep it that way.

These should probably go via Paul's integration branch to avoid
conflicts with the other omap_device/omap_hwmod code.

[PATCH v2 2/2] OMAP: serial: Change device name: omap-hsuart -> omap_uart

[Benoit Cousson]

The naming convention for omap_device is omap_XXX.

Rename the device and driver name in order to stick
to this naming convention.
Remove the hs prefix that is implicit for every OMAP uarts.
