powerpc: p2020: Rename wdt@ nodes to watchdog@

2025-11-11T09:02:47+00:00

The watchdog.yaml schema prescribes a node name of "timer" or "watchdog" rather than the abbreviation "wdt". Signed-off-by: J. Neuschäfer Reviewed-by: Christophe Leroy Signed-off-by: Madhavan Srinivasan Link: https://patch.msgid.link/20250418-watchdog-v1-4-987ff2046272@posteo.net

powerpc/microwatt: Correct ISA version number in device tree

2025-06-23T04:26:28+00:00

The kernel uses 3100 to indicate ISA version 3.1, not 3010, so fix the Microwatt device tree to use 3100. Signed-off-by: Paul Mackerras Signed-off-by: Madhavan Srinivasan Link: https://patch.msgid.link/aB6taMDWvJwOl9xj@bruin

powerpc: dts: mpc8315erdb: Add GPIO controller node

2025-06-13T07:02:21+00:00

The MPC8315E SoC and variants have a GPIO controller at IMMR + 0xc00. This node was previously missing from the device tree. Signed-off-by: J. Neuschäfer Signed-off-by: Madhavan Srinivasan Link: https://patch.msgid.link/20250611-mpc-gpio-v1-1-02d1f75336e2@posteo.net

powerpc/microwatt: Fix model property in device tree

The standard property for the model name is called "model". Signed-off-by: J. Neuschäfer Signed-off-by: Madhavan Srinivasan Link: https://patch.msgid.link/20250611-microwatt-v2-1-80847bbc5f9c@posteo.net

powerpc/microwatt: Add SMP support

2025-02-26T15:46:48+00:00

This adds support for Microwatt systems with more than one core, and updates the device tree for a 2-core version. The secondary CPUs are started and sent to spin in __secondary_hold very early on, in the platform probe function. The reason for doing this is so that they are there when smp_release_cpus() gets called, which is before the platform init_smp function or even the platform setup_arch function gets called. Note that having two CPUs in the device tree doesn't preclude operation with only one CPU. The SYSCON_CPU_CTRL register has a read-only field which indicates the number of CPU cores, so microwatt_init_smp() will only start as many CPU cores as are present in the system, and any extra CPU device-tree nodes will just be ignored.

powerpc/microwatt: Device-tree updates

2025-02-26T15:46:48+00:00

Microwatt now implements ISA v3.1 (SFFS compliancy subset), including prefixed instructions, scv/rfscv, and the FSCR, HFSCR, TAR, and CTRL registers. The privileged mode of operation is now hypervisor mode and there is no privileged non-hypervisor mode; the MSR[HV] bit is forced to 1. Besides updating the ibm,powerpc-cpu-features property to reflect the above, this also makes the following changes relating to peripheral devices: - Add gpio controller. - Remove high-speed property from SD controller, for the case where the interface is connected through 200 ohm protection resisters. - Put an alias for the ethernet in /chosen.
