2022-02-22pinctrl: renesas: r8a77470: Share MMC pin group dataGeert Uytterhoeven1-47/+8
Pin groups mmc_data[14] and sdhi1_data[14] are subsets of mmc_data8. Pin group sdhi1_ctrl can be an alias for mmc_ctrl. This reduces kernel size by 96 bytes.

2022-02-22pinctrl: renesas: Add generic support for resizable busesGeert Uytterhoeven13-1159/+995
The VIN_DATA_PIN_GROUP() macro and vin_data{12,16,} unions are used to define multiple VIN data groups with different numbers of lanes, while referring to a single array of data pins, thus saving memory. However, the same feature would be useful for other resizable buses, like MMC, SDHI, QSPI, LCD, BSC, ... Rework the mechanism for generic use: - Use the new SH_PFC_PIN_GROUP_SUBSET() helper to remove the need for bus-specific unions, - Rename VIN_DATA_PIN_GROUP() to BUS_DATA_PIN_GROUP(), - Rename the macro parameters to better reflect their purposes, - Move the macro up, where it belongs.

2022-02-22pinctrl: renesas: Add generic support for pin group subsetsGeert Uytterhoeven1-0/+12
It is fairly common for the pins in a pin group to be a subset of the pins in another pin group. Add a macro for defining a pin group that refers to a subset of an array of pins.

This is similar to H265 decoding, which also needs double buffer size in comparison to older Cedrus core generations. Increase buffer size to cover H6 needs.

When error occurs in parsing jpeg, the slot isn't acquired yet, it may be the default value MXC_MAX_SLOTS.
