[PATCH v2 10/12] pinctrl: samsung: add exynosautov920 pinctrl

From: Jaewon Kim
Date: Wed Nov 15 2023 - 05:00:16 EST

ExynosAutov920 GPIO has a different register structure.
In the existing Exynos series, EINT control register enumerated after
a specific offset (e.g EXYNOS_GPIO_ECON_OFFSET).
However, in ExynosAutov920 SoC, the register that controls EINT belongs
to each GPIO group, and each GPIO group has 0x1000 align.

This is a structure to protect the GPIO group with S2MPU in VM environment,
and will only be applied in ExynosAuto series SoCs.

Example)
-------------------------------------------------
| original | ExynosAutov920 |
|-----------------------------------------------|
| 0x0 GPIO_CON | 0x0 GPIO_CON |
| 0x4 GPIO_DAT | 0x4 GPIO_DAT |
| 0x8 GPIO_PUD | 0x8 GPIO_PUD |
| 0xc GPIO_DRV | 0xc GPIO_DRV |
| 0x700 EINT_CON | 0x18 EINT_CON |
| 0x800 EINT_FLTCON | 0x1c EINT_FLTCON0 |
| 0x900 EINT_MASK | 0x20 EINT_FLTCON1 |
| 0xa00 EINT_PEND | 0x24 EINT_MASK |
| | 0x28 EINT_PEND |
-------------------------------------------------

Pinctrl data for ExynosAutoV920 SoC.
- GPA0,GPA1 (10): External wake up interrupt
- GPQ0 (2): SPMI (PMIC I/F)
- GPB0,GPB1,GPB2,GPB3,GPB4,GPB5,GPB6 (47): I2S Audio
- GPH0,GPH1,GPH2,GPH3,GPH4,GPH5,GPH6,GPH8 (49): PCIE, UFS, Ethernet
- GPG0,GPG1,GPG2,GPG3,GPG4,GPG5 (29): General purpose
- GPP0,GPP1,GPP2,GPP3,GPP4,GPP5,GPP6,GPP7,GPP8,GPP9,GPP10 (77): USI
