* pinctrl: artpec6: fix __iomem on reg in setBen Dooks (Codethink)2020-01-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The artpec6_pconf_set should have marked reg as __iomem, which ends up making sparse complain about address space conversions. Add the __iomem to silence the following warnings: drivers/pinctrl/pinctrl-artpec6.c:814:13: warning: incorrect type in assignment (different address spaces) drivers/pinctrl/pinctrl-artpec6.c:814:13: expected unsigned int *reg drivers/pinctrl/pinctrl-artpec6.c:814:13: got void [noderef] <asn:2> * drivers/pinctrl/pinctrl-artpec6.c:825:34: warning: incorrect type in argument 1 (different address spaces) drivers/pinctrl/pinctrl-artpec6.c:825:34: expected void const volatile [noderef] <asn:2> *addr drivers/pinctrl/pinctrl-artpec6.c:825:34: got unsigned int *reg drivers/pinctrl/pinctrl-artpec6.c:827:25: warning: incorrect type in argument 2 (different address spaces) drivers/pinctrl/pinctrl-artpec6.c:827:25: expected void volatile [noderef] <asn:2> *addr drivers/pinctrl/pinctrl-artpec6.c:827:25: got unsigned int *reg drivers/pinctrl/pinctrl-artpec6.c:837:34: warning: incorrect type in argument 1 (different address spaces) drivers/pinctrl/pinctrl-artpec6.c:837:34: expected void const volatile [noderef] <asn:2> *addr drivers/pinctrl/pinctrl-artpec6.c:837:34: got unsigned int *reg drivers/pinctrl/pinctrl-artpec6.c:840:25: warning: incorrect type in argument 2 (different address spaces) drivers/pinctrl/pinctrl-artpec6.c:840:25: expected void volatile [noderef] <asn:2> *addr drivers/pinctrl/pinctrl-artpec6.c:840:25: got unsigned int *reg drivers/pinctrl/pinctrl-artpec6.c:850:34: warning: incorrect type in argument 1 (different address spaces) drivers/pinctrl/pinctrl-artpec6.c:850:34: expected void const volatile [noderef] <asn:2> *addr drivers/pinctrl/pinctrl-artpec6.c:850:34: got unsigned int *reg drivers/pinctrl/pinctrl-artpec6.c:853:25: warning: incorrect type in argument 2 (different address spaces) drivers/pinctrl/pinctrl-artpec6.c:853:25: expected void volatile [noderef] <asn:2> *addr drivers/pinctrl/pinctrl-artpec6.c:853:25: got unsigned int *reg drivers/pinctrl/pinctrl-artpec6.c:864:34: warning: incorrect type in argument 1 (different address spaces) drivers/pinctrl/pinctrl-artpec6.c:864:34: expected void const volatile [noderef] <asn:2> *addr drivers/pinctrl/pinctrl-artpec6.c:864:34: got unsigned int *reg drivers/pinctrl/pinctrl-artpec6.c:867:25: warning: incorrect type in argument 2 (different address spaces) drivers/pinctrl/pinctrl-artpec6.c:867:25: expected void volatile [noderef] <asn:2> *addr drivers/pinctrl/pinctrl-artpec6.c:867:25: got unsigned int *reg Signed-off-by: Ben Dooks (Codethink) <ben.dooks@codethink.co.uk> Link: https://lore.kernel.org/r/20191218101602.2442868-1-ben.dooks@codethink.co.uk [Changed unsigned int -> void for the reg pointer] Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* pinctrl: use devm_platform_ioremap_resource() to simplify codeYueHaibing2019-11-051-3/+1
| | | | | | | | | | | | | | | devm_platform_ioremap_resource() internally have platform_get_resource() and devm_ioremap_resource() in it. So instead of calling them separately use devm_platform_ioremap_resource() directly.

* pinctrl: artpec6: Drop unused function and renameLinus Walleij2019-04-111-17/+4
| | | | | | | | | | | | | | | | | The pincontrol callbacks used to be symmetric: enable/disable. However for a while we only have one function that set the muxing, no disabling. Drop the unused disable function, and rename the *enable() function to *set().

* pinctrl: artpec-6: Add smaller groups for uartsJesper Nilsson2018-03-011-16/+50
| | | | | | | | | | | | Add group configuration for uarts that are cut down variants, the standard being full, i.e. all signals, flow control, i.e. rx/tx and cts/rts, and rx/tx only.

* pinctrl: make artpec6 explicitly non-modularPaul Gortmaker2017-04-241-12/+0
| | | | | | | | | | | | | | | | | | | | | | | | | The Kconfig currently controlling compilation of this code is: drivers/pinctrl/Kconfig:config PINCTRL_ARTPEC6 drivers/pinctrl/Kconfig: bool "Axis ARTPEC-6 pin controller driver" ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments.

Add pinctrl driver support for the Axis ARTPEC-6 SoC. There are only some pins that actually have different functions available, but all can control bias (pull-up/-down) and drive strength.
