Subject: [d-kernel] [PATCH kernel-image-6.18/sisyphus 1/2] config: enable PSCI idle and additional 8250 UARTs
Date: Fri, 31 Jul 2026 18:09:29 +0400
Message-ID: <20260731140930.27521-2-heliumium1997@gmail.com> (raw)
In-Reply-To: <20260731140930.27521-1-heliumium1997@gmail.com>

The RK3588 serial aliases expose the Repka Pi 5 Bluetooth controller as
serial9.  The current runtime limit only creates ttyS0 through ttyS7,
leaving ttyS9 unavailable even when UART9 is enabled in the device tree.

Raise the runtime 8250 limit to 16 while keeping the maximum at 192.
Enable the ARM PSCI CPU idle driver so RK3588 CPUs can use
firmware-described idle states.

Keep the platform-independent serial setting in config and the
ARM64-specific idle setting in config-aarch64.
