clk: spacemit: Add support for K1 SoC

2026-07-21T08:31:10Z

The K1 SoC exposes four clock providers in the kernel mainline DT: one PLL controller ("spacemit,k1-pll") and three syscon clock nodes ("spacemit,k1-syscon-{mpmu,apbc,apmu}"). Register a separate U_BOOT_DRIVER for each. The controllers register clocks into a single CCF namespace, and a clock in one controller may parent off a clock owned by another, so a controller must register only after the controllers that own its parents have probed. Each probe forces its parent controllers up by driver: MPMU <- PLL APMU <- PLL, MPMU APBC <- PLL, MPMU, APMU Signed-off-by: Junhui Liu Signed-off-by: Raymond Mao Signed-off-by: Guodong Xu
