2015-07-17pinctrl: Use irq_desc_get_xxx() to avoid redundant lookup of irq_descJiang Liu
Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc while we already have a pointer to corresponding irq_desc.

2015-07-17pinctrl/intel: Use irq_set_handler_locked()Thomas Gleixner
Use irq_set_handler_locked() as it avoids a redundant lookup of the irq descriptor. Search and replacement was done with coccinelle.

2015-06-10pinctrl: make pinctrl_register() return proper error codeMasahiro Yamada
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.

2015-04-07pinctrl: intel: Add Intel Sunrisepoint pin controller and GPIO supportMika Westerberg
This driver supports pinctrl/GPIO hardware found on Intel Sunrisepoint (a Skylake PCH) providing users a pinctrl and GPIO interfaces (including GPIO interrupts). The driver is split into core and platform parts so that the same core driver can be reused in other drivers for other Intel GPIO hardware that is based on the same host controller design.
