2017-08-22pinctrl: bcm281xx: constify pinconf_ops, pinctrl_ops, and pinmux_ops structuresJulia Lawall1-1/+1
This pinconf_ops structure is only stored in the const confops field of a pinctrl_desc structure. Make the pinconf_ops structure const as well. Done with the help of Coccinelle. Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2017-06-09pinctrl: bcm: cleanup Broadcom license headersScott Branden1-7/+2
Use consistent license headers for Broadcom files by placing additional comments outside of standard legal header. Also, update legal header to 2017 format as "Broadcom Corporation" has changed to "Broadcom".

2017-05-29pinctrl: bcm: clean up modular vs. non-modular distinctionsPaul Gortmaker1-8/+8
Fixups here tend to be more of a conglomerate of some of the other repeated/systematic ones we've seen in the earlier pinctrl cleanups. We remove module.h from code that isn't doing anything modular at all; if they have __init sections, then replace it with init.h One driver has a .remove that would be dispatched on module_exit, and as that code is essentially orphaned, so we remove it. In case anyone was previously doing the (pointless) unbind to get to that function, we disable unbind for this one driver as well. A couple bool drivers (hence non-modular) are converted over to to builtin_platform_driver(). Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information was (or is now) contained at the top of the file in the comments.

2017-01-26pinctrl: Widen the generic pinconf argument from 16 to 24 bitsMika Westerberg1-3/+3
The current pinconf packed format allows only 16-bit argument limiting the maximum value 65535. For most types this is enough. However, debounce time can be in range of hundreths of milliseconds in case of mechanical switches so we cannot represent the worst case using the current format. In order to support larger values change the packed format so that the lower 8 bits are used as type which leaves 24 bits for the argument. This allows representing values up to 16777215 and debounce times up to 16 seconds. We also convert the existing users to use 32-bit integer when extracting argument from the packed configuration value.

2016-09-07pinctrl: bcm281xx: constify pinctrl_ops and pinmux_ops structuresJulia Lawall1-2/+2
Check for pinctrl_ops and pinmux_ops structures that are only stored in the pctlops field and the pmxops field, respectively, of a pinctrl_desc structure. These fields are declared const, so pinctrl_ops and pinmux_ops structures that have this property can be declared as const also. The semantic patch that makes this change in the pinctrl_ops is as follows. The pinmux_ops case is similar.

2016-04-01pinctrl: Rename pinctrl_utils_dt_free_map to pinctrl_utils_free_mapIrina Tirdea1-1/+1
Rename pinctrl_utils_dt_free_map to pinctrl_utils_free_map, since it does not depend on device tree despite the current name. This will enforce a consistent naming in pinctr-utils.c and will make it clear it can be called from outside device tree (e.g. from ACPI handling code).

2015-06-10pinctrl: make pinctrl_register() return proper error codeMasahiro Yamada1-2/+2
Currently, pinctrl_register() just returns NULL on error, so the callers can not know the exact reason of the failure. Some of the pinctrl drivers return -EINVAL, some -ENODEV, and some -ENOMEM on error of pinctrl_register(), although the error code might be different from the real cause of the error. This commit reworks pinctrl_register() to return the appropriate error code and modifies all of the pinctrl drivers to use IS_ERR() for the error checking and PTR_ERR() for getting the error code.
