If we attempt to compile serial_sh.c for a system which lacks HSCIF support (e.g. R8A7740), we see the following compilation error:

In file included from drivers/serial/serial_sh.c:20: drivers/serial/serial_sh.c: In function ‘sh_serial_init_generic’: drivers/serial/serial_sh.h:429:35: warning: implicit declaration of function ‘sci_HSSRR_out’; did you mean ‘sci_SCSCR_out’?

To fix this, only try to support access to the HSSRR register for SoCs where it actually exists.

Support for the RZ/G2L will be introduced in following patches, which selects CONFIG_RCAR_64 but does not have HSCIF interfaces, so check for CONFIG_RCAR_GEN2 || CONFIG_RCAR_GEN3 || CONFIG_RCAR_GEN4 to determine if HSCIF is present.

Import bindings for the Port Function Control (PFC) module in the Renesas RZ/G2L SoC family.

This patch is based on the dt-bindings in Linux v6.5 (commit 52e12027d50affbf60c6c9c64db8017391b0c22e).

This driver provides clock and reset control for the Renesas R9A07G044L (RZ/G2L) and R9A07G044C (RZ/G2LC) SoC. It consists of two parts:

* driver code which is applicable to all SoCs in the RZ/G2L family.

* static data describing the clocks and resets which are specific to the R9A07G044{L,C} SoCs. The identifier r9a07g044 (without a final letter) is used to indicate that both SoCs are supported.

clk_set_rate() and clk_get_rate() are implemented only for the clocks that are actually used in u-boot.

The CPG driver is marked with DM_FLAG_PRE_RELOC to ensure that its bind function is called before the SCIF (serial port) driver is probed. This is required so that we can de-assert the relevant reset signal during the serial driver probe function.

This patch is based on the corresponding Linux v6.5 driver (commit 52e12027d50affbf60c6c9c64db8017391b0c22e).

On the Renesas RZ/G2L SoC family, valid GPIO numbers are not contiguous. This is determined by the device tree, where a fixed number of bits are used for the 'pin' number within a 'port', even though not all ports have the same number of pins. The device tree can't be changed here without breaking backwards compatibility in Linux, which we don't want to do.

To avoid printing a status for each of these invalid GPIO numbers when a user executes `gpio status -a`, we allow gpio_get_function() to return -ENOENT when the given offset does not refer to a valid GPIO pin and we skip printing anything if this occurs.

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).

Move the assignment of priv->quirks earlier in the function. This allows us to drop the quirks local variable and makes it easier to maintain clean error handling when we add RZ/G2L support in the next patch.

The ARM TrustedFirmware code for the Renesas RZ/G2L SoC family passes a devicetree blob to the bootloader as an argument in the same was previous R-Car Gen3/Gen4 SoCs. This blob contains a compatible string which can be used to identify the particular SoC we are running on.

We do this as reading the DEVID & PRR registers from u-boot is not sufficient to differentiate between the R9A07G044L (RZ/G2L) and R9A07G044C (RZ/G2LC) SoCs. An additional read from offset 0x11861178 is needed but this address is in the OTP region which can only be read from the secure world (i.e. TrustedFirmware). So we have to rely on TrustedFirmware to determine the SoC and pass this information to u-boot via an fdt blob.
