Subject: [RFC PATCH 0/2] RZ/G2UL separate out SoC specific parts
Date: Thu, 29 Sep 2022 18:23:54 +0100 [thread overview]
Message-ID: <20220929172356.301342-1-prabhakar.mahadev-lad.rj@bp.renesas.com> (raw)
From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>
Hi All,
This patch series aims to split up the RZ/G2UL SoC DTSI into common parts
so that this can be shared with the RZ/Five SoC.
Implementation is based on the discussion [0] where I have used option#2.
The Renesas RZ/G2UL (ARM64) and RZ/Five (RISC-V) have almost the same
identical blocks to avoid duplication a base SoC dtsi (r9a07g043.dtsi) is
created which will be used by the RZ/G2UL (r9a07g043u.dtsi) and RZ/Five
(r9a07g043F.dtsi)
Sending this as an RFC to get some feedback.
r9a07g043f.dtsi will look something like below:
#include <dt-bindings/interrupt-controller/irq.h>
#define SOC_PERIPHERAL_IRQ_NUMBER(nr) (nr + 32)
#define SOC_PERIPHERAL_IRQ(nr, na) SOC_PERIPHERAL_IRQ_NUMBER(nr) na
#include <arm64/renesas/r9a07g043.dtsi>
/ {
...
...
};
Although patch#2 can be merged into patch#1 just wanted to keep them separated
for easier review.
