Replace by more specific (c files)

2026-07-03T05:38:17+00:00

Replace the #include of  by the more specific
 where applicable. For most cases the include
can be dropped completely, only a few drivers need one or two headers
added.

soc: renesas: rcar-mfis: Add R-Car V4H/V4M support

2026-05-29T12:42:29+00:00

The above SoCs have a weird register layout for the mailbox registers.
So, encapsulate register offset calculation in a per-SoC callback. Other
than that, only a separate config struct and compatibles are needed.

soc: renesas: Identify R-Car R8A779MD M3Le SoC

2026-05-25T10:03:04+00:00

Add support for identifying the R-Car M3Le (R8A779MD) SoC.

The Renesas R-Car R8A779MD M3Le SoC is a variant of the already
supported R-Car M3-N SoC with reduced peripherals.
Enable support for the M3Le SoC through already existing ARCH_R8A77965
configuration symbol.  PRR reads 0x67c05501.

Use the of_machine_get_match() helper to avoid accessing of_root
directly, which is planned to become private.

soc: renesas: Add R-Car X5H PRR support

2026-05-04T09:58:59+00:00

On R-Car X5H, PRR is inside the MFIS memory block, so we need to access
it similar to e.g. RZ/G2L.

soc: renesas: Add Renesas R-Car MFIS driver

2026-05-04T09:58:54+00:00

Renesas R-Car MFIS offers multiple features but most importantly
mailboxes and hwspinlocks. Because they share a common register space
and a common register unprotection mechanism, a single driver was chosen
to handle all dependencies. (MFD and auxiliary bus have been tried as
well, but they failed because of circular dependencies.)

In this first step, the driver implements common register access and a
mailbox controller. hwspinlock support will be added incrementally, once
the subsystem allows out-of-directory drivers.
