[PATCH] gpio: cosmetics: remove needless newlines

2006-07-15T04:53:54+00:00

- pure cosmetics: lose needless newlines.

- rename EXPORTed gpio vtables from {scx200,pc8736x}_access to _gpio_ops new
  name is much closer to the vtable-name struct nsc_gpio_ops, should be
  clearer.  Also rename the _fops vtable var to _fileops to better
  disambiguate it from the gpio vtable.

[PATCH] chardev: GPIO for SCx200 & PC-8736x: display pin values in/out in gpio_dump

2006-06-28T00:32:43+00:00

Add current pin settings to gpio_dump() output.  This adds the last 'word' to
the syslog lines, which displays the input and output values that the pin is
set to.

  pc8736x_gpio.0: io00: 0x0044 TS OD PUE  EDGE LO DEBOUNCE        io:1/1

The 2 values may differ for a number of reasons:
1- the pin output circuitry is diaabled, (as the above 'TS' indicates)
2- it needs a pullup resistor to drive the attached circuit,
3- the external circuit needs a pullup so the open-drain has something
   to pull-down
4- the pin is wired to Vcc or Ground

It might be appropriate to add a WARN for 2,3,4, since they could
damage the chip and/or circuit, esp if misconfig goes unnoticed.

[PATCH] chardev: GPIO for SCx200 & PC-8736x: use dev_dbg in common module

2006-06-28T00:32:43+00:00

Use of dev_dbg() and friends is considered good practice.  dev_dbg() needs a
struct device *devp, but nsc_gpio is only a helper module, so it doesnt
have/need its own.  To provide devp to the user-modules (scx200 & pc8736x
_gpio), we add it to the vtable, and set it during init.

Also squeeze nsc_gpio_dump()'s format a little.

[PATCH] chardev: GPIO for SCx200 & PC-8736x: add new pc8736x_gpio module

2006-06-28T00:32:43+00:00

Add the brand new pc8736x_gpio driver.  This is mostly based upon
scx200_gpio.c, but the platform_dev is treated separately, since its fairly
big too.

[PATCH] chardev: GPIO for SCx200 & PC-8736x: migrate gpio_dump to common module

2006-06-28T00:32:43+00:00

Since the meaning of config-bits is the same for scx200 and pc8736x _gpios, we
can share a function to deliver this to user.  Since it is called via the
vtable, its also completely replaceable.  For now, we keep using printk...

[PATCH] chardev: GPIO for SCx200 & PC-8736x: migrate file-ops to common module

2006-06-28T00:32:43+00:00

Now that the read(), write() file-ops are dispatching gpio-ops via the vtable,
they are generic, and can be moved 'verbatim' to the nsc_gpio common-support
module.  After the move, various symbols are renamed to update 'scx200_' to
'nsc_', and headers are adjusted accordingly.

[PATCH] chardev: GPIO for SCx200 & PC-8736x: add empty common-module

Add the nsc_gpio common-support module as an empty shell.  Next patch starts
the migration of the common gpio support routines.
