pinctrl: nuvoton: wpcm450: Fix build error without OF

pinctrl: nuvoton: Fix return value check in wpcm450_gpio_register()

2022-03-24T19:10:32Z

In case of error, the function devm_platform_ioremap_resource() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().

CONFIG_GENERIC_PINCTRL_GROUPS must be selected in order for struct group_desc to be defined in pinctrl/core.h. Add the missing select line to CONFIG_PINCTRL_WPCM450.

pinctrl: nuvoton: Fix sparse warning

Sparse complains: drivers/pinctrl/nuvoton/pinctrl-wpcm450.c:626:9: sparse: sparse: obsolete array initializer, use C99 syntax This is because no equal sign is between the array index and the assignments, in the macro.

pinctrl: nuvoton: Add driver for WPCM450

2022-03-15T00:16:20Z

This driver is based on the one for NPCM7xx, because the WPCM450 is a predecessor of those SoCs. Notable differences: - On WPCM450, the GPIO registers are not organized in multiple banks, but rather placed continually into the same register block. This affects how register offsets are computed. - Pinmux nodes can explicitly select GPIO mode, whereas in the npcm7xx driver, this happens automatically when a GPIO is requested. Some functionality implemented in the hardware was (for now) left unused in the driver, specifically blinking and pull-up/down.

pinctrl: nuvoton: npcm7xx: Rename DS() macro to DSTR()

2022-02-11T01:03:53Z

The name "DS" is defined in arch/x86/um/shared/sysdep/ptrace_64.h, which results in a compiler warning when build-testing on ARCH=um. Rename this driver's "DS" macro to DSTR so avoid this collision.

pinctrl: nuvoton: npcm7xx: Use %zu printk format for ARRAY_SIZE()

2022-02-11T01:03:53Z

When compile-testing on 64-bit architectures, GCC complains about the mismatch of types between the %d format specifier and value returned by ARRAY_LENGTH(). Use %zu, which is correct everywhere.

pinctrl: npcm: Fix broken references to chip->parent_device

2022-02-10T11:07:04Z

The npcm driver has a bunch of references to the irq_chip parent_device field, but never sets it. Fix it by fishing that reference from somewhere else, but it is obvious that these debug statements were never used. Also remove an unused field in a local data structure.
