From: Claudiu Beznea <claudiu.beznea.uj@xxxxxxxxxxxxxx> Hi, The Renesas RZ/G3S SoC has 6 serial interfaces. One of them is used as debug console (and it is already enabled in the current code base). Series adds support for the remaining ones. Patches: - 01/08 - adds clock, reset and power domain support for the serial interfaces - 02/08 - serial driver fix patch identified while adding RZ/G3S support - 03/08 - extends suspend to RAM support on the serial driver for the RZ/G3S SoC - 04-08/08 - add device tree support Merge strategy, if any: - patch 01/08 can go through Renesas tree - patches 02-03/08 can go through serial tree - patches 04-08/08 can go through Renesas tree Thank you, Claudiu Beznea Changes in v3: - in patch "serial: sh-sci: Check if TX data was written to device in .tx_empty()": -- check the status of the DMA transaction in tx_empty() -- changed the variable name that tracks if TX occurred Changes in v2: - drop patch "serial: sh-sci: Clean sci_ports[0] after at earlycon exit" from v1 as it was already applied - used bool instead of atomic_t in patch "serial: sh-sci: Check if TX data was written to device in .tx_empty()" Claudiu Beznea (8): clk: renesas: r9a08g045: Add clock, reset and power domain for the remaining SCIFs serial: sh-sci: Check if TX data was written to device in .tx_empty() serial: sh-sci: Update the suspend/resume support arm64: dts: renesas: r9a08g045: Add the remaining SCIF interfaces arm64: dts: renesas: rzg3s-smarc: Fix the debug serial alias arm64: dts: renesas: rzg3s-smarc-switches: Add a header to describe different switches arm64: dts: renesas: rzg3s-smarc: Enable SCIF3 arm64: dts: renesas: r9a08g045s33-smarc-pmod: Add overlay for SCIF1 arch/arm64/boot/dts/renesas/Makefile | 3 + arch/arm64/boot/dts/renesas/r9a08g045.dtsi | 90 +++++++++++++++++++ .../dts/renesas/r9a08g045s33-smarc-pmod.dtso | 48 ++++++++++ .../boot/dts/renesas/rzg3s-smarc-som.dtsi | 25 +----- .../boot/dts/renesas/rzg3s-smarc-switches.h | 32 +++++++ arch/arm64/boot/dts/renesas/rzg3s-smarc.dtsi | 25 +++++- drivers/clk/renesas/r9a08g045-cpg.c | 20 +++++ drivers/tty/serial/sh-sci.c | 79 ++++++++++++++-- 8 files changed, 288 insertions(+), 34 deletions(-) create mode 100644 arch/arm64/boot/dts/renesas/r9a08g045s33-smarc-pmod.dtso create mode 100644 arch/arm64/boot/dts/renesas/rzg3s-smarc-switches.h -- 2.39.2
