When setting a pin direction verify that the requested direction is supported, and return an error if it isn't. This requires pin configuration information to be supplied by SoC data. The check is a no-op if the information is not supplied. Signed-off-by:

Set pin configuration type to - PINMUX_TYPE_NONE at initialization time and when disabling a function or freeing a GPIO - PINMUX_TYPE_FUNCTION when enabling a function - PINMUX_TYPE_INPUT or PINMUX_TYPE_OUTPUT when setting the GPIO direction Verify that the type is PINMUX_TYPE_NONE when enabling a function or requesting a GPIO and return -EBUSY if it isn't.

The sh_pfc_reconfig_pin() is only called from a single location. Merge it into its call site to make the code easier to follow. Signed-off-by:

Laurent Pinchart authored
The existing PFC pinconf implementation, tied to the PFC-specific pin types, isn't used by drivers or boards. Replace it with the generic pinconf types to implement bias (pull-up/down) setup. Other pin configuration options can be implemented later if needed. Signed-off-by:

The purpose of the dry-run is to ensure that a pin about to be configured isn't in use. However, the current implementation is a no-op. This proves that the dry-run isn't essential. Remove it. Freeing configuration then becomes a no-op as well. Remove it. Signed-off-by:

The sh_pfc_pin structure supplied in SoC data contains information about pin configuration and name. It's abused to store GPIO data registers information and pin config type. Move those fields out of the pinmux_data_reg structure into the new sh_pfc_gpio_pin and sh_pfc_pin_config structures. Signed-off-by:

The pinmux_data_reg structure supplied in SoC data contains information about data registers. It's abused to store per-device mapped iomem and shadow values. Move those fields out of the pinmux_data_reg structure into the per-device sh_pfc_chip structure. Signed-off-by:

Now that all PFC platform devices provide memory resources support for registers without an associated memory resource isn't used anymore. Drop it. Signed-off-by:

Laurent Pinchart authored
All data registers are located in the same memory resource. Locate the mapped resource at initializat time and use it directly instead of computing a mapped address for each register. This gets rid of the mapped_reg field of the pinmux_data_reg structure. Signed-off-by:

Move the sh_pfc_setup_data_regs(), sh_pfc_setup_data_reg(), sh_pfc_get_data_reg(), sh_pfc_read_bit() and sh_pfc_write_bit() function to gpio.c as they belong to the GPIO implementation. Inline sh_pfc_read_bit() and sh_pfc_write_bit() in their only call location. Signed-off-by:

In case of error, the function pinctrl_register() returns NULL not ERR_PTR(). The IS_ERR() test in the return value check should be replaced with NULL test. Signed-off-by:

Add memory resources for the pin control platform device to let the sh-pfc driver ioremap() registers properly instead of evily casting register physical addresses to virtual addresses. The memory resource address range has been extracted from the config and data registes lists in the sh-pfc driver. Signed-off-by: -
