pinctrl: restore pin naming

2012-02-01T18:35:21Z

Commit ca53c5f1ca5c936777caca46b7c716a40682ce83 ("pinctrl: conjure names for unnamed pins") made pins lose their identity and only get autogenerated names. Acked-by: Stephen Warren Signed-off-by: Linus Walleij

pinctrl: add checks for empty function names

2012-01-26T13:13:11Z

This is needed as otherwise we can get the following when dealing with buggy data in a pinmux driver for pinmux_search_function: Unable to handle kernel NULL pointer dereference at virtual address 00000000 ... PC is at strcmp+0xc/0x34 LR is at pinmux_get+0x350/0x8f4 ... As we need pctldev initialized to call ops->list_functions, let's initialize it before check_ops calls and pass the pctldev to the check_ops functions. Do this for both pinmux and pinconf check_ops functions. Signed-off-by: Tony Lindgren Signed-off-by: Linus Walleij

pinctrl: fix pinmux_hog_maps when ctrl_dev_name is not set

2012-01-26T13:13:05Z

The ctrl_dev_name is optional for struct pinmux_map assuming that ctrl_dev is set. Without this patch we can get: Unable to handle kernel NULL pointer dereference at virtual address 00000000 ... (pinmux_hog_maps+0xa4/0x20c) (pinctrl_register+0x2a4/0x378) ... Fix this by adding adding a test for map->ctrl_dev. Additionally move the test for map->ctrl_dev earlier to optimize out the loop a bit. Signed-off-by: Tony Lindgren Acked-by: Stephen Warren Signed-off-by: Linus Walleij

pinctrl: fix some pinmux typos

2012-01-26T13:11:31Z

Fix some pinmux typos so implementing pinmux drivers is a bit easier. Signed-off-by: Tony Lindgren Signed-off-by: Linus Walleij

pinctrl: free debugfs entries when unloading a pinmux driver

2012-01-24T22:03:02Z

We were not cleaning up properly after unloading a pinmux driver compiled as module. Signed-off-by: Tony Lindgren Signed-off-by: Linus Walleij

pinctrl: unbreak error messages

2012-01-24T21:47:46Z

It's better to not line break error messages to allow easier grepping for them even when the line gets >80 chars. Additionally some minor reformating is done. Signed-off-by: Uwe Kleine-König Signed-off-by: Linus Walleij

pinctrl: fix pinconf_pins_show iteration

2012-01-20T16:55:49Z

Commit 706e852 "pinctrl: correct a offset while enumerating pins" modified the variable used by pinconf_pin_show()'s for loop, but didn't update the for loop test expression. Signed-off-by: Stephen Warren Signed-off-by: Linus Walleij

pinctrl: remove unnecessary max pin number

2012-01-03T08:10:09Z

This patch removes maxpin member in the pin control descriptor because we don't need this value as we enumerate a pin space using offset. Signed-off-by: Chanho Park Signed-off-by: Kyungmin Park Signed-off-by: Linus Walleij

pinctrl: correct a offset while enumerating pins

2012-01-03T08:10:09Z

This patch modifies a offset while enumerating pins to support a partial pin space. If we use a pin number for enumerating pins, the pin space always starts with zero base. Indeed, we always check the pin is in the pin space. An extreme example, there is only two pins. One is 0. Another is 1000. We always enumerate whole offsets until 1000. For solving this problem, we use the offset of the pin array instead of the zero-based pin number.
