Signed-off-by: Soren Brinkmann Tested-by: Andreas Färber --- Changes since v2: - driver-specific DT properties are passed to the core in two arrays, one for the actual DT parsing one for the debugfs representation. Issue a compiler warning when the number of entries is not the same for both arrays. Changes since v1: - fix EMIO_SD1_CD pin name - add USB to pinmux options changes since RFCv2: - let Zynq select PINCTRL_ZYNQ. Boot hangs when pinctrl information is present in DT but no driver available. - add #defines to get rid of magical constants - add commas at end of initializers - separate changes in mach-zynq in separate patch - add driver specific io-standard DT property - refactored pinconf set function to not require arguments for argument-less properties - squash other patches in - support for IO-standard property - support for low-power mode property - migration to pinconf_generic_dt_node_to_map_all() - use newly created infrastructure to add pass driver-specific DT params to pinconf-generic changes since RFC: - use syscon/regmap to access registers in SLCR space - rebase to 3.18: rename enable -> set_mux - add kernel-doc - support pinconf - supported attributes - pin-bias: pull up, tristate, disable - slew-rate: 0 == slow, 1 == fast; generic pinconf does not display argument --- drivers/pinctrl/Kconfig | 8 + drivers/pinctrl/Makefile | 1 + drivers/pinctrl/pinctrl-zynq.c | 1176 ++++++++++++++++++++++++++++++++++++++++ 3 files changed, 1185 insertions(+) create mode 100644 drivers/pinctrl/pinctrl-zynq.c diff --git a/drivers/pinctrl/Kconfig b/drivers/pinctrl/Kconfig index d014f22f387a..67c8db927454 100644 --- a/drivers/pinctrl/Kconfig +++ b/drivers/pinctrl/Kconfig @@ -191,6 +191,14 @@ config PINCTRL_PALMAS open drain configuration for the Palmas series devices like TPS65913, TPS80036 etc. +config PINCTRL_ZYNQ + bool "Pinctrl driver for Xilinx Zynq" + depends on ARCH_ZYNQ + select PINMUX + select GENERIC_PINCONF + help + This selectes the pinctrl driver for Xilinx Zynq. + source "drivers/pinctrl/berlin/Kconfig" source "drivers/pinctrl/freescale/Kconfig" source "drivers/pinctrl/intel/Kconfig" diff --git a/drivers/pinctrl/Makefile b/drivers/pinctrl/Makefile index c030b3db8034..886357556e87 100644 --- a/drivers/pinctrl/Makefile +++ b/drivers/pinctrl/Makefile @@ -35,6 +35,7 @@ obj-$(CONFIG_PINCTRL_XWAY) += pinctrl-xway.o obj-$(CONFIG_PINCTRL_LANTIQ) += pinctrl-lantiq.o obj-$(CONFIG_PINCTRL_TB10X) += pinctrl-tb10x.o obj-$(CONFIG_PINCTRL_ST) += pinctrl-st.o +obj-$(CONFIG_PINCTRL_ZYNQ) += pinctrl-zynq.o obj-$(CONFIG_ARCH_BERLIN) += berlin/ obj-y += freescale/ diff --git a/drivers/pinctrl/pinctrl-zynq.c b/drivers/pinctrl/pinctrl-zynq.c new file mode 100644 index 000000000000..c2fc9035dde9 --- /dev/null +++ b/drivers/pinctrl/pinctrl-zynq.c @@ -0,0 +1,1176 @@ +/* + * Zynq pin controller + * + * Copyright (C) 2014 Xilinx + * + * Sören Brinkmann + * + * This program is free software: you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation, either version 2 of the License, or + * (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
