This driver adds support for the gpio features of the GPIO/PFC module in
the Renesas RZ/G2L (R9A07G044) SoC.
The new `rzg2l-pfc-gpio` driver is bound to the same device tree node as
the `rzg2l-pfc-pinctrl` driver as the same hardware block provides both
GPIO and pin multiplexing features.
This patch is based on the corresponding Linux v6.5 driver
(commit 52e12027d50affbf60c6c9c64db8017391b0c22e).

This driver adds support for the pinctrl features of the GPIO/PFC module
in the Renesas RZ/G2L (R9A07G044) SoC.
A multi-function `rzg2l-pfc` driver is defined for UCLASS_NOP, which
binds the `rzg2l-pfc-pinctrl` UCLASS_PINCTRL driver dynamically. We also
define common macros and functions for the PFC in <renesas/rzg2l-pfc.h>.
This makes it easy to add an additional UCLASS_GPIO driver for the GPIO
functionality of this module in a follow-up patch.

Currently, the Renesas pin control driver supports pins that can switch
their I/O voltage levels between either 1.8V and 3.3V, or between 2.5V
and 3.3V. However, some SoCs have pins that can switch between 1.8V and
2.5V.
Add support for this by replacing the separate SH_PFC_PIN_CFG_IO_VOLTAGE
capability and voltage level flags by a 2-bit field, to cover three
possible I/O voltage switching options.

On RK3568 most pins have a configurable drive strength of level 0-5 and
some pins level 0-11. When rk3568_set_drive is called with a strength
value above 7 the drv value written to reg may overflow into the write
enable bits, resulting in a bad configuration.
This cause e.g. ethernet PHY on Radxa CM3-IO board not to work after
drive is configured according to the device tree.
Could not get PHY for ethernet@fe010000: addr 0
Level 6-11 can be configured using a second reg for some pins, however
the drv value is reused resulting in lower 6 bits being written to reg.
Input schmitt is configured in 2-bit fields on RK3568 compared to
earlier generation and 2'b10 should be used to enable input schmitt.
Change to use regmap_update_bits with a rmask to fix the overflow issue
and closer match the linux driver. Bit shift the drv value used for the
second reg to configure drive strength level 6-11. Also write correct
values for input schmitt setting.

There exists a situation of the mediatek pinctrl driver that may return
wrong pin function value for the pinmux driver:
- All pin function arrays are defined without const
- Some pin function arrays contain all-zero value, e.g.:
static int mt7622_spi_funcs[] = { 0, 0, 0, 0, 0, 0, };
- These arrays will be put into .bss section during compilation
- .bss section has no "a" attribute and does not exist in the final binary
file after objcopy.
- FDT binary blob is appended to the u-boot binary, which occupies the
.bss section.
- During board_f stage, .bss has not been initialized, and contains the
data of FDT, which is not full-zero data.
- pinctrl driver is initialized in board_f stage, and it will get wrong
data if another driver is going to set default pinctrl.
Since pinmux information and soc data are only meant to be read-only, thus
should be declared as const. This will force all pinctrl data being put
into .rodata section. Since .rodata has "a" attribute, even the all-zero
data will be allocated and filled with correct value in to u-boot binary.

Commit dafe0fbfb0 ("pinctrl: mediatek: rewrite mtk_pinconf_set and
related functions") changed the logic deciding to set R0 and R1
registers for V1 devices.
Before:
/* Also set PUPD/R0/R1 if the pin has them */
err = mtk_hw_set_value(dev, pin, PINCTRL_PIN_REG_PUPD, !pullup);
if (err != -EINVAL) {
mtk_hw_set_value(dev, pin, PINCTRL_PIN_REG_R0, r0);
mtk_hw_set_value(dev, pin, PINCTRL_PIN_REG_R1, r1);
}
After:
/* try pupd_r1_r0 if pullen_pullsel return error */
err = mtk_pinconf_bias_set_pullen_pullsel(dev, pin, disable, pullup,
val);
if (err)
return mtk_pinconf_bias_set_pupd_r1_r0(dev, pin, disable,
pullup, val);
Tracing mtk_pinconf_bias_set_pullen_pullsel shows that the function
always either returns 0 in case of success or -EINVAL in case any error
has occurred. Hence the logic responsible of the decision to program R0
and R1 has been inverted.
This leads to problems on BananaPi R2 (MT7623N) when booting from
SDMMC, it turns out accessing eMMC no longer works since
U-Boot 2022.07:
MT7623> mmc dev 0
Card did not respond to voltage select! : -110
The problem wasn't detected for a long time as both eMMC and SDMMC work
fine if they are used to boot from, and hence R0 and R1 were already
setup by the bootrom and/or preloader.
Fix the logic to restore the originally intended and correct behavior
and also change the descriptive comment accordingly.
