Subject: [PATCH 0/2] renesas: r8a779g0: Add missing SCIF_CLK2
Date: Thu, 18 Jan 2024 17:32:35 +0100	[thread overview]
Message-ID: <cover.1705589612.git.geert+renesas@glider.be> (raw)

	Hi all,

R-Car V4H actually has two SCIF_CLK pins.
The second pin provides the SCIF_CLK signal for HSCIF2 and SCIF4.
The first pin provides the SCIF_CLK signal for the other (H)SCIF
instances.

This patch series adds the missing SCIF_CLK2 pin group/function to the
R-Car V4H pin control driver and to the R-Car V4H DTS file, and fixes
the HSCIF2 and SCIF4 DT descriptions to refer to the proper clock.

As SCIF_CLK2 cannot be used on the White Hawk development board, I could
not test proper operation of HSCIF2 and SCIF4.  I did verify that HSCIF2
and SCIF4 do not operate properly when trying to use (the first and thus
incorrect) SCIF_CLK as the clock source.

I plan to queue these in renesas-pinctrl resp. renesas-devel for v6.9.

Thanks for your comments!
