pinctrl: sh-pfc: only use dummy states for non-DT platforms

2016-03-30T08:57:51+00:00

If pinctrl_provide_dummies() is used unconditionally, then the dummy state will be used even on DT platforms when the "init" state was intentionally left out. Instead of "default", the dummy "init" state will then be used during probe. Thus, when probing an I2C controller on cold boot, communication triggered by bus notifiers broke because the pins were not initialized. Do it like OMAP2: use the dummy state only for non-DT platforms.

pinctrl: sh-pfc: core: don't open code of_device_get_match_data()

2016-03-09T03:46:50+00:00

This change will also make Coverity happy by avoiding a theoretical NULL pointer dereference; yet another reason is to use the above helper function to tighten the code and make it more readable. Signed-off-by: Wolfram Sang Acked-by: Geert Uytterhoeven Signed-off-by: Linus Walleij

pinctrl: sh-pfc: make explicitly non-modular

2016-03-09T03:23:19+00:00

The Kconfig / Makefile currently controlling compilation of this code is: drivers/pinctrl/sh-pfc/Makefile:obj-$(CONFIG_PINCTRL_SH_PFC) += sh-pfc.o drivers/pinctrl/sh-pfc/Makefile:sh-pfc-objs = core.o pinctrl.o drivers/pinctrl/sh-pfc/Kconfig:config PINCTRL_SH_PFC drivers/pinctrl/sh-pfc/Kconfig: def_bool y ...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. Since module_init already wasn't being used in this code, the init ordering remains unchanged with this commit. 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 was (or is now) contained at the top of the file in the comments.

pinctrl: sh-pfc: Use ARCH_RENESAS

2016-02-26T09:04:21+00:00

Make use of ARCH_RENESAS in place of ARCH_SHMOBILE. This is part of an ongoing process to migrate from ARCH_SHMOBILE to ARCH_RENESAS the motivation for which being that RENESAS seems to be a more appropriate name than SHMOBILE for the majority of Renesas ARM based SoCs.

pinctrl: sh-pfc: Rework PFC GPIO support

2016-02-18T08:30:58+00:00

The sh-pfc pinctrl driver is currently handling SoC-specific PFC hardware blocks on ARM64, ARM and SH architectures. For older SoCs using SH cores and some 32-bit ARM SoCs the PFC hardware also provides GPIO functionality. On the majority of 32-bit ARM SoCs from Renesas and so far all ARM64 SoCs the GPIO feature is provided by separate hardware blocks. So far GPIO support in the PFC driver has been compiled-in for the majority of the SoCs, but with this patch applied the SoCs with PFC support may select from one of the following: - CONFIG_PINCTRL_SH_PFC - Used if PFC lacks GPIO hardware - CONFIG_PINCTRL_SH_PFC_GPIO - Used if PFC includes GPIO support This patch results in the following changes: - The GPIO functionality is only compiled-in on relevant SoCs - The number of lines of code is reduced Build tested using the following configurations: - r8a7795 -> CONFIG_PINCTRL_SH_PFC_GPIO=n -> OK (ARM64) - r8a7790 -> CONFIG_PINCTRL_SH_PFC_GPIO=n -> OK (ARM) - r8a7790 + r8a7740 -> CONFIG_PINCTRL_SH_PFC_GPIO=y -> OK (ARM) - r8a7740 -> CONFIG_PINCTRL_SH_PFC_GPIO=y -> OK (ARM) - sh7751 -> CONFIG_PINCTRL_SH_PFC=n -> OK (SH rts7751r2d1) - sh7724 -> CONFIG_PINCTRL_SH_PFC_GPIO=y -> OK (SH ecovec24) Signed-off-by: Magnus Damm Acked-by: Laurent Pinchart [geert: s/def_bool n/bool/] Signed-off-by: Geert Uytterhoeven
