The e10133 workaround was broken in two places:
- The code intended to temporarily mask all interrupts in GPC_IMRx_CORE0. While the old register values were saved, the actual masking was missing.
- imx_udelay() expects the system counter to run at its base frequency, but the system counter is switched to a lower frequency earlier in psci_system_suspend(), leading to a much longer delay than intended. Replace the call with an equivalent loop (linux-imx 5.15 does the same)
This fixes the SoC hanging forever when there was already a wakeup IRQ pending while suspending. Fixes: 57b620255e ("imx: mx7: add system suspend/resume support") Signed-off-by: Matthias Schiffer matthias.schiffer@ew.tq-group.com
Applied to u-boot-imx, master, thanks !
