Merge tag 'pinctrl-for-v3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pinctrl changes from Linus Walleij: "Some of this stuff is hitting arch/arm/* and have been ACKed by the ARM SoC folks, or it's device tree bindings pertaining to the specific driver. These are the bulk pinctrl changes for kernel v3.7: - Add subdrivers for the DB8540 and NHK8815 Nomadik-type ASICs, provide platform config for the Nomadik. - Add a driver for the i.MX35. - Add a driver for the BCM2835, an advanced GPIO expander. - Various fixes and clean-ups and minor improvements for the core, Nomadik, pinctr-single, sirf drivers. - Some platform config for the ux500." * tag 'pinctrl-for-v3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (27 commits) pinctrl: add bcm2835 driver pinctrl: clarify idle vs sleep states pinctrl/nomadik: use irq_find_mapping() pinctrl: sirf: add lost chained_irq_enter and exit in sirfsoc_gpio_handle_irq pinctrl: sirf: initialize the irq_chip pointer of pinctrl_gpio_range pinctrl: sirf: fix spinlock deadlock in sirfsoc_gpio_set_input pinctrl: sirf: add missing pins to pinctrl list pinctrl: sirf: fix a typo in sirfsoc_gpio_probe pinctrl: pinctrl-single: add debugfs pin h/w state info ARM: ux500: 8500: update I2C sleep states pinctrl pinctrl: Fix potential memory leak in pinctrl_register_one_pin() ARM: ux500: tidy up pin sleep modes ARM: ux500: fix spi2 pin group pinctrl: imx: remove duplicated const pinctrl: document semantics vs GPIO ARM: ux500: 8500: use hsit_a_2 group for HSI pinctrl: use kasprintf() in pinmux_request_gpio() pinctrl: pinctrl-single: Add pinctrl-single,bits type of mux pinctrl/nomadik : add MC1_a_2 pin MC1 function group list pinctrl: pinctrl-single: Make sure we do not change bits outside of mask ...
