Add driver for Sunplus SP7021 SoC. Signed-off-by: Wells Lu <wellslutw@gmail.com> --- Changes in V6 - Addressed comments of Mr. Rob Herring. - Changed name of vendor property: sunplus,zero_func --> sunplus,zerofunc - Addedssed comments of Mr. Andy Shevchenko - Modified Kconfig (bool -> tristate) and Makefile to support 'compile as module'. - Re-ordered some header files. - Removed some useless comments. - Added some inline functions to simplify coding. - Removed checking existing of property "gpio-controller". - Removed redundant 'check_mul_overflow()' after a devm_kcalloc() function. - Added include <linux/types.h> in 'sppctl.h' - Modified and added some kernel-doc comments. - Fixed some wrong comment style of multi-line. - Moved struct sppctl_gpio_chip { ... }; to 'sppctl.c'. - Others MAINTAINERS | 1 + drivers/pinctrl/Kconfig | 1 + drivers/pinctrl/Makefile | 1 + drivers/pinctrl/sunplus/Kconfig | 22 + drivers/pinctrl/sunplus/Makefile | 6 + drivers/pinctrl/sunplus/sppctl.c | 1118 +++++++++++++++++++++++++++++++ drivers/pinctrl/sunplus/sppctl.h | 170 +++++ drivers/pinctrl/sunplus/sppctl_sp7021.c | 583 ++++++++++++++++ 8 files changed, 1902 insertions(+) create mode 100644 drivers/pinctrl/sunplus/Kconfig create mode 100644 drivers/pinctrl/sunplus/Makefile create mode 100644 drivers/pinctrl/sunplus/sppctl.c create mode 100644 drivers/pinctrl/sunplus/sppctl.h create mode 100644 drivers/pinctrl/sunplus/sppctl_sp7021.c
