[PATCH v2 0/4] arm: sunplus: add SP7021 LTPP3G2 board support

[Andrew Gaylard]

The Tibbo LTPP3G2 is a board based on the Sunplus SP7021 SoC:
https://tibbo.com/store/tps/ltpp3g2.html
It is the platform that underpins Tibbo's IoT products.

This series adds board support to linux-next:

 - Patch 1: vendor prefix for Tibbo Technology Inc.
 - Patch 2: device tree nodes for SP7021 peripherals that have upstream
             drivers (PWM, watchdog, eMMC), plus a label on the
             gpio-leds node so board DTS files can override it.
 - Patch 3: board DTS for the LTPP3G2, covering eMMC, SPI, RTC,
             a bit-banged I2C EEPROM, PWM, watchdog, and two GPIO LEDs.
 - Patch 4: sp7021_defconfig updates to enable the drivers used by the
             LTPP3G2 and correct a few defaults.

Tested on a LTPP3G2, booting via eMMC, on linux-next-20260915.

Changes in v2:
 - fix issues spotted by sashiko-bot.
