clk: COMMON_CLK_RPMI should depend on RISCV (2025-10-01 19:07:43 -0600)
----------------------------------------------------------------
RISC-V updates for the v6.18 merge window (part two)
Second set of RISC-V updates for the v6.18 merge window, consisting
of:
- Support for the RISC-V-standardized RPMI interface.
RPMI is a platform management communication mechanism between OSes
running on application processors, and a remote platform management
processor. Similar to ARM SCMI, TI SCI, etc. This includes irqchip,
mailbox, and clk changes.
- Support for the RISC-V-standardized MPXY SBI extension.
MPXY is a RISC-V-specific standard implementing a shared memory
mailbox between S-mode operating systems (e.g., Linux) and M-mode
firmware (e.g., OpenSBI). It is part of this PR since one of its
use cases is to enable M-mode firmware to act as a single RPMI client
for all RPMI activity on a core (including S-mode RPMI activity).
Includes a mailbox driver.
- Some ACPI-related updates to enable the use of RPMI and MPXY.
- The addition of Linux-wide memcpy_{from,to}_le32() static inline
functions, for RPMI use.
- An ACPI Kconfig change to enable boot logos on any ACPI-using
architecture (including RISC-V)
- A RISC-V defconfig change to add GPIO keyboard and event device
support, for front panel shutdown or reboot buttons
This PR also includes a recent, one-line Kconfig patch from Geert to
keep non-RISC-V users from being asked about building the RPMI virtual
clock driver when !COMPILE_TEST. THere's nothing preventing
non-RISC-V SoCs from implementing RPMI, but until some users show up,
let's not annoy others with it.
