Merge tag 'pinctrl-v4.7-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control updates from Linus Walleij: "This kernel cycle was quite calm when it comes to pin control and there is really just one major change, and that is the introduction of devm_pinctrl_register() managed resources. Apart from that linear development, details below. Core changes: - Add the devm_pinctrl_register() API and switch all applicable drivers to use it, saving lots of lines of code all over the place. New drivers: - driver for the Broadcom NS2 SoC - subdriver for the PXA25x SoCs - subdriver for the AMLogic Meson GXBB SoC Driver improvements: - the Intel Baytrail driver now properly supports pin control - Nomadik, Rockchip, Broadcom BCM2835 support the .get_direction() callback in the GPIO portions - continued development and stabilization of several SH-PFC SoC subdrivers: r8a7795, r8a7790, r8a7794 etc" * tag 'pinctrl-v4.7-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (85 commits) Revert "pinctrl: tegra: avoid parked_reg and parked_bank" pinctrl: meson: Fix eth_tx_en bit index pinctrl: tegra: avoid parked_reg and parked_bank pinctrl: tegra: Correctly check the supported configuration pinctrl: amlogic: Add support for Amlogic Meson GXBB SoC pinctrl: rockchip: fix pull setting error for rk3399 pinctrl: stm32: Implement .pin_config_dbg_show() pinctrl: nomadik: hide nmk_gpio_get_mode when unused pinctrl: ns2: rename pinctrl_utils_dt_free_map pinctrl: at91: Merge clk_prepare and clk_enable into clk_prepare_enable pinctrl: at91: Make at91_gpio_template const pinctrl: baytrail: fix some error handling in debugfs pinctrl: ns2: add pinmux driver support for Broadcom NS2 SoC pinctrl: sirf/atlas7: trivial fix of spelling mistake on flagged pinctrl: sh-pfc: Kill unused variable in sh_pfc_remove() pinctrl: nomadik: implement .get_direction() pinctrl: nomadik: use BIT() with offsets consequently pinctrl: exynos5440: Use off-stack memory for pinctrl_gpio_range pinctrl: zynq: Use devm_pinctrl_register() for pinctrl registration pinctrl: u300: Use devm_pinctrl_register() for pinctrl registration ...
