The divided clock is SD0_DIV4. SD0_DIV4 is registered with CLK_SET_RATE_PARENT which means a rate request for it is propagated to the MUX and could reach rzg2l_cpg_sd_clk_mux_set_parent() concurrently with the users of SD0. Add proper locking to avoid concurrent access on SD MUX set rate registers.

Hardware user's manual (r01uh0914ej0130-rzg2l-rzg2lc.pdf) specifies that setting 0 is prohibited. The rzg2l_cpg_sd_clk_mux_get_parent() should just read CPG_PL2SDHI_DSEL, trust the value and return the proper clock parent index based on the read value. Do this.

This will be used in RZ/G3S by SDHI, SPI, OCTA, I, I2, I3, P0, P1, P2, P3 core clocks. The divider has some limitation for SDHI and OCTA clocks: - SD div cannot be 1 if parent rate is 800MHz - OCTA div cannot be 1 if parent rate is 400MHz For these clocks a notifier could be registered from platform specific clock driver and proper actions are taken before clock rate is changed, if needed.

RZ/G3S CPG module is almost identical with the one available in RZ/G2{L, UL} the exception being some core clocks as follows: - SD clock is composed by a mux and a divider and the divider has some limitation (div = 1 cannot be set if mux rate is 800MHz). - there are 3 SD clocks - OCTA and TSU clocks are specific to RZ/G3S - PLL1/4/6 are specific to RZ/G3S with its own computation formula Even with this RZ/G3S could use the same bindings as RZ/G2L.

Some of these macros received as argument the hardware port identifier, some hardware port offset address (e.g. ISEL() received port identifier, IOLH() received port offset address). This makes hard to extend the current driver for SoCs were port identifiers are not continuous in memory map of pin controller. This is the case for RZ/G3S pin controller were ports are mapped as follows: port offset port identifier ----------- --------------- 0x20 P0 0x21 P5 0x22 P6 0x23 P11 0x24 P12 0x25 P13 0x26 P14 0x27 P15 0x28 P16 0x29 P17 0x2a P18 0x30 P1 0x31 P2 0x32 P3 0x33 P4 0x34 P7 0x35 P8 0x36 P8 0x37 P10 To make this achievable change all the above macros used to get the address of a port register for specific port functionality based on port hardware address. Shortly, all the above macros will get as argument the port offset address listed in the above table. With this RZG2L_SINGLE_PIN_GET_PORT_OFFSET() and RZG2L_PIN_ID_TO_PORT_OFFSET() were replaced by RZG2L_PIN_CFG_TO_PORT_OFFSET(), RZG2L_SINGLE_PIN_GET_CFGS() and RZG2L_GPIO_PORT_GET_CFGS() were replaced by RZG2L_PIN_CFG_TO_CAPS(). Also rzg2l_pinctrl_set_pfc_mode() don't need port argument anymore. Also rzg2l_gpio_direction_input() and rzg2l_gpio_direction_output() don't need to translate port and bit locally as this can be done by rzg2l_gpio_set_direction(). To use the same naming for port, bit/pin and register offset the port_offset variable names in different places was replaced by variable named off and there is no need to initialize anymore cfg and bit in different code places.

For function1 register need to be configured with 0, for function8 register need to be configured with 7. We cannot use zero based addressing when requesting functions from different code places as documentation (RZG3S_pinfunction_List_r1.0.xlsx) states explicitly that function0 has different meaning. For this add a new member to struct rzg2l_hwcfg that will keep the offset that need to be substracted before applying a value to PFC register.

On each group there could be up to 4 drive strength values per power source. Available power sources are 1v8, 2v5, 3v3. Drive strength values are fine tuned than what was previously available on the driver thus the necessity of having micro-amp support. As drive strength and power source values are linked togheter the hardware setup for these was moved at the end of rzg2l_pinctrl_pinconf_set() to ensure proper validation of the new values. The drive strength values are expected to be initialized though SoC specific hardware configuration data structure.

SoM contains the following devices: - RZ/G3S microcontroller: Renesas R9A08G045S33GBG - 9-channel PMIC: Renesas RAA215300 - Clock Generator: Renesas 5L35023B - 128M QSPI Flash: Renesas AT25QL128A - 8G LPDDR4 SDRAM: Micron MT53D512M16D1DS-046 - 64GB eMMC Flash: Micron MTFC64GBCAQTC - 2x Gigabit Ethernet Transceiver: Microchip KSZ9131RNX - 5x Current Monitors: Renesas ISL28025FR12Z The following interfaces are available on SoM board: - 2 uSD interfaces - 12-pin, 1.0mm pitch connector to the RZ/G3S ADC IO - 4-pin, 1.0mm pitch connector to the RZ/G3S I3C IO - JTAG connector At the moment the 24MHz output of 5L35023B, memory SD ch0 (with all its bits) were described in device tree. SD channel 0 of RZ/G3S is connected to an uSD card interface and an eMMC. The selection b/w them is done though a hardware switch. The DT will select b/w uSD and eMMC though SW_SD0_DEV_SEL build flag.
