This patch fixes a compilation error when CONFIG_PM_DEVICE is enabled without CONFIG_PM_DEVICE_RUNTIME and CONFIG_POWER_DOMAIN. Upstream-status: available Signed-off-by: Martin Hoff <[email protected]> (cherry picked from commit 94ed533)
The HAL used by the SiWx91x SoC implements a mechanism to protect atomic sections. Since this HAL also supports a zero-latency interrupt (ZLI) mechanism, we need to ensure the same number of bits are used for ZLI interrupts. The interrupt priority level (2) depends on a hardcoded value in the Simplicity SDK (CORE_ATOMIC_BASE_PRIORITY_LEVEL). Without this fix, arch_irq_lock (which sets the BASEPRI register to 0x4 when zero-latency interrupts are not enabled) is overridden by CORE_EnterAtomic in the HAL, which sets BASEPRI to 0xC since the HAL does not use the BASEPRI_MAX function. IRQ might then fires since it's register with a lowest priority in Zephyr. Upstream-status: available Signed-off-by: Martin Hoff <[email protected]> (cherry picked from commit 87ab3e3)
entropy_get_entropy() is allowed to block while waiting for entropy. Don't exit with an error if entropy is exhausted, wait instead. Move clock enable out of the inner loop to avoid unnecessarily calling it multiple times. Upstream-status: available Signed-off-by: Aksel Skauge Mellbye <[email protected]> (cherry picked from commit ad867a1)
