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: - 01/04 - extends suspend to RAM support on the serial driver for the RZ/G3S SoC - 02-04/04 - add device tree support Merge strategy, if any: - patch 01/04 can go through the serial tree - patches 02-04/04 can go through the Renesas tree Thank you, Claudiu Beznea Changes in v4: - dropped fixes and clock patches as they were applied independently - dropped DT patches that were already applied - addressed review comments 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 (4): serial: sh-sci: Update the suspend/resume support 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 ++ .../r9a08g045s33-smarc-pmod1-type-3a.dtso | 48 +++++++++++++++++ .../boot/dts/renesas/rzg3s-smarc-som.dtsi | 20 +------ .../boot/dts/renesas/rzg3s-smarc-switches.h | 40 ++++++++++++++ arch/arm64/boot/dts/renesas/rzg3s-smarc.dtsi | 13 +++++ drivers/tty/serial/sh-sci.c | 53 +++++++++++++++---- 6 files changed, 149 insertions(+), 28 deletions(-) create mode 100644 arch/arm64/boot/dts/renesas/r9a08g045s33-smarc-pmod1-type-3a.dtso create mode 100644 arch/arm64/boot/dts/renesas/rzg3s-smarc-switches.h -- 2.43.0
