2018-03-01pinctrl: artpec-6: Add smaller groups for uartsJesper Nilsson1-16/+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. This allows us to be more precise in which pins we're actually using. Signed-off-by: Jesper Nilsson <jesper.nilsson@axis.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2017-08-22pinctrl: artpec6: constify pinconf_ops, pinctrl_ops, and pinmux_ops structuresJulia Lawall1-1/+1
This pinctrl_ops structure is only stored in the const pctlops field of a pinctrl_desc structure. Make the pinctrl_ops structure const as well. Done with the help of Coccinelle.

2017-04-28pinctrl: artpec6: Fix return value check in artpec6_pmx_probe()Wei Yongjun1-2/+2
In case of error, the function pinctrl_register() returns ERR_PTR() not NULL. The NULL test in the return value check should be replaced with IS_ERR().

2017-04-24pinctrl: make artpec6 explicitly non-modularPaul Gortmaker1-12/+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.

2017-04-07pinctrl: Add pincontrol driver for ARTPEC-6 SoCJesper Nilsson1-0/+992
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. Code originally written by Chris Paterson. Signed-off-by: Jesper Nilsson <jesper.nilsson@axis.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
