sh-pfc: fix sparse GPIOs for R-Car SoCs

2015-07-20T09:01:52+00:00

The PFC driver causes the kernel to hang on the R-Car gen2 SoC based boards when the CPU_ALL_PORT() macro is fixed to reflect the reality, i.e. when the GPIO space becomes actually sparse. This happens because the _GP_GPIO() macro includes an indexed initializer which causes the "holes" (array entries filled with all 0s) between the groups of the existing GPIOs; and the driver can't cope with that. There seems to be no reason to use the indexed initializer, so we can remove the index specifier and so avoid the "holes".

pinctrl: sh-pfc: add R8A7794 PFC support

2015-06-16T08:53:20+00:00

Add PFC support for the R8A7794 SoC including pin groups for some on-chip devices such as ETH, I2C, INTC, MSIOF, QSPI, [H]SCIF... Sergei: squashed together several patches, fixed the MLB_CLK typo, added IRQ4.. IRQ9 pin groups, fixed IRQn comments, added ETH B pin group names, removed stray new line and fixed typos in the comments in the pinmux_config_regs[] initializer, removed the platform device ID, took into account limited number of signals in the GPIO1/5/6 controllers, added reasonable and removed unreasonable copyrights, modified the bindings document, renamed, added changelog. Changes in version 5: - resolved rejects, refreshed the patch; - added Laurent Pinchart's ACK. Changes in version 4: - reused the PORT_GP_26() macro to #define PORT_GP_28(). Changes in version 3: - removed the platform device ID; - added PORT_GP_26() and PORT_GP_28() macros, used them for GPIO1/5/6 in the CPU_ALL_PORT() macro. Changes in version 2: - rebased the patch.

pinctrl: make pinctrl_register() return proper error code

2015-06-10T12:49:52+00:00

Currently, pinctrl_register() just returns NULL on error, so the callers can not know the exact reason of the failure. Some of the pinctrl drivers return -EINVAL, some -ENODEV, and some -ENOMEM on error of pinctrl_register(), although the error code might be different from the real cause of the error. This commit reworks pinctrl_register() to return the appropriate error code and modifies all of the pinctrl drivers to use IS_ERR() for the error checking and PTR_ERR() for getting the error code.

pinctrl: sh-pfc: r8a73a4: Remove obsolete multi-platform check

2015-05-12T11:17:44+00:00

As of commit 9d07d414d4c33d86 ("ARM: shmobile: r8a73a4: ape6evm: Remove legacy platform"), r8a73a4 is only supported in generic ARM multi-platform builds. Hence CONFIG_ARCH_MULTIPLATFORM is always set, and the check can be removed. Signed-off-by: Geert Uytterhoeven Acked-by: Laurent Pinchart Acked-by: Simon Horman Signed-off-by: Linus Walleij
