Staging: olpc_dcon: Removed more completed TODO entries

2013-08-21T17:02:28+00:00

1. Console event notifier support: No one I've asked knows what this
all about.
2. Audit code for unnecessary code: This is done.
3. Verify sane i2cAPI usage: This is also done.

Staging: olpc_dcon: Already completed TODO entry removed

2013-08-19T22:29:23+00:00

The TODO entry - drop global variables, use a proper olpc_dcon_priv
struct - is already finished. The driver has no global variables.
It uses the private structure 'dcon_priv'.

Staging: olpc_dcon: more big endian conformity

2013-08-16T00:23:16+00:00

Using an int which is casted to unsigned char as inbuf is messy.
The code won't work on big endian systems.  The patch should fix
this.

Staging: olpc_dcon: replace some magic numbers

2013-08-16T00:22:27+00:00

This patch replace some magic numbers. I believe it makes
the driver more readable.

The magic number 0x26 is the XO system embedded controller
(EC) command 'DCON power enable/disable'.

Number 0x41, and 0x42 are special memory controller settings
register.  The 0x41 initialize bit sequence 0x101 means:
enable memory power down function and special SDRAM clock
delay for synchronize SDRAM output and clock signal.

The 0x42 initialize squence 0x101 is wrong.  According to
the specification Bit 8 is reserved, thus not in use.
I removed it.

staging: olpc_dcon: provide detailed FB_OLPC_DCON help section

2013-08-01T00:33:37+00:00

The FB_OLPC_DCON help section is to short according to checkpatch.pl.
We want more information about the controller type, its task, its video
pipeline position and so on.

There are no style issues, remove checkpatch.pl TODO entry.

Staging: olpc_dcon: change to msleep to usleep_range

2013-07-25T20:38:09+00:00

The resolution of msleep is related to HZ, so with HZ set to
100 any msleep of less then 10ms will become ~10ms. This is
not what we want. Use usleep_range to get more control of
what is happening here.

staging: olpc_dcon: remove use of __devexit_p

2012-11-21T23:05:00+00:00

CONFIG_HOTPLUG is going away as an option so __devexit_p is no longer
needed.
