pinctrl: iproc: Fix iProc and NSP GPIO support

2016-10-31T20:25:15Z

Since commit 44a7185c2ae6 ("of/platform: Add common method to populate default bus"), ARM64 platform devices are populated at the arch_initcall_sync level; as a result, the platform_driver_probe calls in both the iProc and NSP GPIO drivers fail with -ENODEV since by that time the platform device was not yet registered. Replace platform_driver_probe with platform_driver_register, that allow the device to be register later Fixes: 44a7185c2ae6 ("of/platform: Add common method to populate default bus") Signed-off-by: Ray Jui Tested-by: Eric Anholt Signed-off-by: Linus Walleij

pinctrl: bcm281xx: constify pinctrl_ops and pinmux_ops structures

2016-09-07T20:41:30Z

Check for pinctrl_ops and pinmux_ops structures that are only stored in the pctlops field and the pmxops field, respectively, of a pinctrl_desc structure. These fields are declared const, so pinctrl_ops and pinmux_ops structures that have this property can be declared as const also. The semantic patch that makes this change in the pinctrl_ops is as follows. The pinmux_ops case is similar.

pinctrl: iproc: Add NSP and Stingray GPIO support

2016-07-22T14:47:51Z

The iProc GPIO controller is shared among multiple iProc based SoCs. In the NSP integration, the drive strength pinctrl function is disabled. In the integration of Stingray, pinctrl is handled by another block and this GPIO controller is solely used as a GPIO controller, and therefore should not be registered to the pinconf framework This patch introduces new SoC specific compatible strings "brcm,iproc-nsp-gpio" for NSP with drive strength feature disabled and "brcm,iproc-stingray-gpio" for Stingray with all PINCONF features disabled This patch is developed based on the initial work from Yendapally Reddy Dhananjaya who attempted to disable drive strength configuration for the iProc based NSP chip. In addition, Pramod Kumar also contributed to make the support more generic across all currently supported PINCONF functions in the iProc GPIO/PINCONF driver Signed-off-by: Pramod Kumar Signed-off-by: Ray Jui Signed-off-by: Linus Walleij

pinctrl: bcm: add OF dependencies

2016-07-22T14:43:32Z

Building without CONFIG_OF gives us these warnings for the broadcom pinctrl drivers: drivers/pinctrl/bcm/pinctrl-nsp-mux.c:356:20: error: 'pinconf_generic_dt_node_to_map_group' undeclared here (not in a function) drivers/pinctrl/bcm/pinctrl-cygnus-mux.c:739:20: error: 'pinconf_generic_dt_node_to_map_group' undeclared here (not in a function) The function is only available when CONFIG_OF is set, so we should add a Kconfig dependency for both drivers.
