The QingKe V2C has an integer multiplier but no divide. Add support for the corresponding Zmmul extension and, as the extension was added in GCC 13.0, add a test for the compiler version. Signed-off-by: Michael Hope <[email protected]>
The CH32V006 and others in the CH32V00x series are an evolution of the CH32V003 and use different remap offsets for the various peripherals. In the same way as the CH32V20x, fork the CH32V003 driver and add CH32V00x support. Signed-off-by: Michael Hope <[email protected]>
The CH32V006 is part of the CH32V00x series of 32 bit RISC-V microcontrollers. This series is an evolution of the CH32V003 which was used as a basis for this Devicetree definition. Compared to the CH32V003, thie CH32V006 has an extra GPIO port (PB), an extra UART (UART2), 8 KiB of RAM, 62 KiB of flash, and uses the QingKe V2C core.

Compared to the CH32V003, the CH32V00x series is an evolution that uses a different microarchitecture (V2C instead of V2A) and different pinctrl mappings. Fork the current qingke_v2a and use the new proposed naming convention. Signed-off-by: Michael Hope <[email protected]>
Expand the current systick compatibility to include the CH32V00x series. Change the HAL compatibility to include all of the CH32V family. Signed-off-by: Michael Hope <[email protected]>
The flash latency needs to be configured before switching to the high speed clock. Set the latency based on the CH32V003 and CH32V00x reference manual. Signed-off-by: Michael Hope <[email protected]>
The WCH CH32V006EVT is an evaluation board for the RISC-V based CH32V006K8U6 SOC. The board is equipped with a power LED, reset button, USB port for power, and two user LEDs. Add the board definition, documentation, and sample overlay. Signed-off-by: Michael Hope <[email protected]>

The WCH CH32V00x series is an evolution of the CH32V003 that adds more RAM, flash, and peripherals. Add support for the series, the CH32V006, and the CH32V006EVT.
Tested via the blinky and watchdog samples that show that the LEDs, UART, and watchdog work.
