16) Sending "git pull" requests (from Linus emails)
|
||||
|

Please write the git repo address and branch name alone on the same line
|

so that I can't even by mistake pull from the wrong branch, and so
|
||||
that a triple-click just selects the whole thing.
|
||||
|
||||
So the proper format is something along the lines of:
|
||||
|
||||
"Please pull from
|
||||
|
||||
git://jdelvare.pck.nerim.net/jdelvare-2.6 i2c-for-linus
|
||||
|
||||
to get these changes:"
|
||||
|
||||
so that I don't have to hunt-and-peck for the address and inevitably
|
||||
get it wrong (actually, I've only gotten it wrong a few times, and
|
||||
checking against the diffstat tells me when I get it wrong, but I'm
|
||||
just a lot more comfortable when I don't have to "look for" the right
|
||||
thing to pull, and double-check that I have the right branch-name).
|
||||
|
||||
|
||||
Please use "git diff -M --stat --summary" to generate the diffstat:
|
||||
the -M enables rename detection, and the summary enables a summary of
|
||||
new/deleted or renamed files.
|
||||
|
||||
With rename detection, the statistics are rather different [...]
|
||||
because git will notice that a fair number of the changes are renames.

Upgrading I2C Drivers to the new 2.6 Driver Model
|
||||
=================================================

Ben Dooks <ben-linux@fluff.org>

||||
Introduction
|
||||
------------
|
||||
|
||||
This guide outlines how to alter existing Linux 2.6 client drivers from
|
||||
the old to the new new binding methods.
|
||||
|
||||
|
||||
Example old-style driver
|
||||
------------------------
|
||||
|
||||
|
||||
struct example_state {
|
||||
struct i2c_client client;
|
||||
....
|
||||
};
|
||||
|
||||
static struct i2c_driver example_driver;
|
||||
|
||||
static unsigned short ignore[] = { I2C_CLIENT_END };
|
||||
static unsigned short normal_addr[] = { OUR_ADDR, I2C_CLIENT_END };
|
||||
|
||||
I2C_CLIENT_INSMOD;
|
||||
|
||||
static int example_attach(struct i2c_adapter *adap, int addr, int kind)
|
||||
{
|
||||
struct example_state *state;
|
||||
struct device *dev = &adap->dev; /* to use for dev_ reports */
|
||||
int ret;
|
||||
|
||||
state = kzalloc(sizeof(struct example_state), GFP_KERNEL);
|
||||
if (state == NULL) {
|
||||
dev_err(dev, "failed to create our state\n");
|
||||
return -ENOMEM;
|
||||
}
|
||||
|
||||
example->client.addr = addr;
|
||||
example->client.flags = 0;
|
||||
example->client.adapter = adap;
|
||||
|
||||
i2c_set_clientdata(&state->i2c_client, state);
|
||||
strlcpy(client->i2c_client.name, "example", I2C_NAME_SIZE);
|
||||
|
||||
ret = i2c_attach_client(&state->i2c_client);
|
||||
if (ret < 0) {
|
||||
dev_err(dev, "failed to attach client\n");
|
||||
kfree(state);
|
||||
return ret;
|
||||
}
|
||||
|
||||
dev = &state->i2c_client.dev;
|
||||
|
||||
/* rest of the initialisation goes here. */
|
||||
|
||||
dev_info(dev, "example client created\n");
|
||||
|
||||
return 0;
|
||||
}
|
||||
|
||||
static int __devexit example_detach(struct i2c_client *client)
|
||||
{
|
||||
struct example_state *state = i2c_get_clientdata(client);
|
||||
|
||||
i2c_detach_client(client);
|
||||
kfree(state);
|
||||
return 0;
|
||||
}
|
||||
|
||||
static int example_attach_adapter(struct i2c_adapter *adap)
|
||||
{
|
||||
return i2c_probe(adap, &addr_data, example_attach);
|
||||
}
|
||||
|
||||
static struct i2c_driver example_driver = {
|
||||
.driver = {
|
||||
.owner = THIS_MODULE,
|
||||
.name = "example",
|
||||
},
|
||||
.attach_adapter = example_attach_adapter,
|
||||
.detach_client = __devexit_p(example_detach),
|
||||
.suspend = example_suspend,
|
||||
.resume = example_resume,
|
||||
};
|
||||
|
||||
|
||||
Updating the client
|
||||
-------------------
|
||||
|
||||
The new style binding model will check against a list of supported
|
||||
devices and their associated address supplied by the code registering
|
||||
the busses. This means that the driver .attach_adapter and
|
||||
.detach_adapter methods can be removed, along with the addr_data,
|
||||
as follows:
|
||||
|
||||
- static struct i2c_driver example_driver;
|
||||
|
||||
- static unsigned short ignore[] = { I2C_CLIENT_END };
|
||||
- static unsigned short normal_addr[] = { OUR_ADDR, I2C_CLIENT_END };
|
||||
|
||||
- I2C_CLIENT_INSMOD;
|
||||
|
||||
- static int example_attach_adapter(struct i2c_adapter *adap)
|
||||
- {
|
||||
- return i2c_probe(adap, &addr_data, example_attach);
|
||||
- }
|
||||
|
||||
static struct i2c_driver example_driver = {
|
||||
- .attach_adapter = example_attach_adapter,
|
||||
- .detach_client = __devexit_p(example_detach),
|
||||
}
|
||||
|
||||
Add the probe and remove methods to the i2c_driver, as so:
|
||||
|
||||
static struct i2c_driver example_driver = {
|
||||
+ .probe = example_probe,
|
||||
+ .remove = __devexit_p(example_remove),
|
||||
}
|
||||
|
||||
Change the example_attach method to accept the new parameters
|
||||
which include the i2c_client that it will be working with:
|
||||
|
||||
- static int example_attach(struct i2c_adapter *adap, int addr, int kind)
|
||||
+ static int example_probe(struct i2c_client *client,
|
||||
+ const struct i2c_device_id *id)
|
||||
|
||||
Change the name of example_attach to example_probe to align it with the
|
||||
i2c_driver entry names. The rest of the probe routine will now need to be
|
||||
changed as the i2c_client has already been setup for use.
|
||||
|
||||
The necessary client fields have already been setup before
|
||||
the probe function is called, so the following client setup
|
||||
can be removed:
|
||||
|
||||
- example->client.addr = addr;
|
||||
- example->client.flags = 0;
|
||||
- example->client.adapter = adap;
|
||||
-
|
||||
- strlcpy(client->i2c_client.name, "example", I2C_NAME_SIZE);
|
||||
|
||||
The i2c_set_clientdata is now:
|
||||
|
||||
- i2c_set_clientdata(&state->client, state);
|
||||
+ i2c_set_clientdata(client, state);
|
||||
|
||||
The call to i2c_attach_client is no longer needed, if the probe
|
||||
routine exits successfully, then the driver will be automatically
|
||||
attached by the core. Change the probe routine as so:
|
||||
|
||||
- ret = i2c_attach_client(&state->i2c_client);
|
||||
- if (ret < 0) {
|
||||
- dev_err(dev, "failed to attach client\n");
|
||||
- kfree(state);
|
||||
- return ret;
|
||||
- }
|
||||
|
||||
|
||||
Remove the storage of 'struct i2c_client' from the 'struct example_state'
|
||||
as we are provided with the i2c_client in our example_probe. Instead we
|
||||
store a pointer to it for when it is needed.
|
||||
|
||||
struct example_state {
|
||||
- struct i2c_client client;
|
||||
+ struct i2c_client *client;
|
||||
|
||||
the new i2c client as so:
|
||||
|
||||
- struct device *dev = &adap->dev; /* to use for dev_ reports */
|
||||
+ struct device *dev = &i2c_client->dev; /* to use for dev_ reports */
|
||||
|
||||
And remove the change after our client is attached, as the driver no
|
||||
longer needs to register a new client structure with the core:
|
||||
|
||||
- dev = &state->i2c_client.dev;
|
||||
|
||||
In the probe routine, ensure that the new state has the client stored
|
||||
in it:
|
||||
|
||||
static int example_probe(struct i2c_client *i2c_client,
|
||||
const struct i2c_device_id *id)
|
||||
{
|
||||
struct example_state *state;
|
||||
struct device *dev = &i2c_client->dev;
|
||||
int ret;
|
||||
|
||||
state = kzalloc(sizeof(struct example_state), GFP_KERNEL);
|
||||
if (state == NULL) {
|
||||
dev_err(dev, "failed to create our state\n");
|
||||
return -ENOMEM;
|
||||
}
|
||||
|
||||
+ state->client = i2c_client;
|
||||
|
||||
Update the detach method, by changing the name to _remove and
|
||||
to delete the i2c_detach_client call. It is possible that you
|
||||
can also remove the ret variable as it is not not needed for
|
||||
any of the core functions.
|
||||
|
||||
- static int __devexit example_detach(struct i2c_client *client)
|
||||
+ static int __devexit example_remove(struct i2c_client *client)
|
||||
{
|
||||
struct example_state *state = i2c_get_clientdata(client);
|
||||
|
||||
- i2c_detach_client(client);
|
||||
|
||||
And finally ensure that we have the correct ID table for the i2c-core
|
||||
and other utilities:
|
||||
|
||||
+ struct i2c_device_id example_idtable[] = {
|
||||
+ { "example", 0 },
|
||||
+ { }
|
||||
+};
|
||||
+
|
||||
+MODULE_DEVICE_TABLE(i2c, example_idtable);
|
||||
|
||||
static struct i2c_driver example_driver = {
|
||||
.driver = {
|
||||
.owner = THIS_MODULE,
|
||||
.name = "example",
|
||||
},
|
||||
+ .id_table = example_ids,
|
||||
|
||||
|
||||
Our driver should now look like this:
|
||||
|
||||
struct example_state {
|
||||
struct i2c_client *client;
|
||||
....
|
||||
};
|
||||
|
||||
static int example_probe(struct i2c_client *client,
|
||||
const struct i2c_device_id *id)
|
||||
{
|
||||
struct example_state *state;
|
||||
struct device *dev = &client->dev;
|
||||
|
||||
state = kzalloc(sizeof(struct example_state), GFP_KERNEL);
|
||||
if (state == NULL) {
|
||||
dev_err(dev, "failed to create our state\n");
|
||||
return -ENOMEM;
|
||||
}
|
||||
|
||||
state->client = client;
|
||||
i2c_set_clientdata(client, state);
|
||||
|
||||
/* rest of the initialisation goes here. */
|
||||
|
||||
dev_info(dev, "example client created\n");
|
||||
|
||||
return 0;
|
||||
}
|
||||
|
||||
static int __devexit example_remove(struct i2c_client *client)
|
||||
{
|
||||
struct example_state *state = i2c_get_clientdata(client);
|
||||
|
||||
kfree(state);
|
||||
return 0;
|
||||
}
|
||||
|
||||
static struct i2c_device_id example_idtable[] = {
