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.
