| | * | | pinctrl: renesas: r8a7740: Optimize fixed-width reserved fieldsGeert Uytterhoeven2022-05-051-35/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Describe registers with fixed-width register fields and many reserved fields using the PINMUX_CFG_REG_VAR() macro, as the latter supports a shorthand not requiring dummy values. This reduces kernel size by 230 bytes.

| | * | | pinctrl: renesas: Add shorthand for reserved register fieldsGeert Uytterhoeven2022-05-052-19/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, reserved register fields must be fully described using dummy enum IDs (zeroes), one for each possible state (2^bits states). Add support for describing reserved fields using negative field width values as shorthands, thus removing the need for dummy values. Apart from the obvious size reduction due to the removal of the dummy values, this will also enable merging adjacent reserved fields into a single field, reducing the number of fields to describe, and thus kernel size. Update the checker accordingly.
