Hello, This is the second version of the patch set adds device tree bindings for the sh sci serial port devices and adds OF parsing to the sh-sci driver. The bindings are based on Bastian Hecht's proposal (see http://www.spinics.net/lists/arm-kernel/msg228129.html). The approach taken here is more minimalistic: instead of describing all hardware characteristics that vary between the SCI device revisions in DT (such as registers layout), that information is stored in the driver and selected based on the compatible property value. Only SCI revisions used on ARM devices are supported through DT, as DT support for SuperH is nowhere down the line. Patches 01/29 to 06/29 clean up the sh-sci driver. Patches 07/29 to 27/29 replace memory and interrupt resources passed through platform data with platform resources. Beside replacing a custom mechanism with a standard one, it will also make the DT parsing code simpler as resource allocation will be shared between DT and non-DT code paths. Finally, patches 28/29 to 29/29 add OF parsing to the sh-sci driver and create DT bindings documentation. The patches have been test on a Lager board (r8a7790-based). Support for other SoCs will be added as needed. Note that all current Renesas ARM SoCs seem to be compatible with the generic (H)SCI(F)(AB) devices, but the plan is for their DT bindings to list the SoC-specific version in case incompatibilities are found later. Patch 08/29 ("serial: sh-sci: Support resources passed through platform resources") is the only dependency of the arch/arm and arch/sh patches present in this series. As it's too late to get it in v3.13, Simon will need a stable branch of the linux serial tree with that patch included. Changes compared to v1: - Patches 04/29 to 27/29 have been added - Multi-interrupt support has been removed from the DT bindings as they don't support any SoC requiring multi-interrupt yet Cc: devicetree@xxxxxxxxxxxxxxx Bastian Hecht (1): serial: sh-sci: Add OF support Laurent Pinchart (28): serial: sh-sci: Sort headers alphabetically serial: sh-sci: Remove baud rate calculation algorithm 5 serial: sh-sci: Simplify baud rate calculation algorithms serial: sh-sci: Remove duplicate interrupt check in verify port op serial: sh-sci: Set the UPF_FIXED_PORT flag serial: sh-sci: Don't check IRQ in verify port operation serial: sh-sci: Support resources passed through platform resources ARM: shmobile: sh7372: Use macros to declare SCIF devices ARM: shmobile: sh73a0: Use macros to declare SCIF devices ARM: shmobile: r8a7740: Use macros to declare SCIF devices ARM: shmobile: r8a7779: Use macros to declare SCIF devices ARM: shmobile: r7s72100: Don't define SCIF platform data in an array ARM: shmobile: r8a73a4: Don't define SCIF platform data in an array ARM: shmobile: r8a7778: Don't define SCIF platform data in an array ARM: shmobile: r8a7790: Don't define SCIF platform data in an array ARM: shmobile: r8a7791: Don't define SCIF platform data in an array ARM: shmobile: sh7372: Declare SCIF register base and IRQ as resources ARM: shmobile: sh73a0: Declare SCIF register base and IRQ as resources ARM: shmobile: r7s72100: Declare SCIF register base and IRQ as resources ARM: shmobile: r8a73a4: Declare SCIF register base and IRQ as resources ARM: shmobile: r8a7740: Declare SCIF register base and IRQ as resources ARM: shmobile: r8a7778: Declare SCIF register base and IRQ as resources ARM: shmobile: r8a7779: Declare SCIF register base and IRQ as resources ARM: shmobile: r8a7790: Declare SCIF register base and IRQ as resources ARM: shmobile: r8a7791: Declare SCIF register base and IRQ as resources sh: Declare SCIF register base and IRQ as resources serial: sh-sci: Remove platform data mapbase and irqs fields serial: sh-sci: Add device tree bindings documentation .../bindings/serial/renesas,sci-serial.txt | 42 ++++ arch/arm/mach-shmobile/setup-r7s72100.c | 63 +++--- arch/arm/mach-shmobile/setup-r8a73a4.c | 65 +++--- arch/arm/mach-shmobile/setup-r8a7740.c | 196 +++-------------- arch/arm/mach-shmobile/setup-r8a7778.c | 45 ++-- arch/arm/mach-shmobile/setup-r8a7779.c | 129 +++-------- arch/arm/mach-shmobile/setup-r8a7790.c | 117 +++++----- arch/arm/mach-shmobile/setup-r8a7791.c | 130 +++++------ arch/arm/mach-shmobile/setup-sh7372.c | 161 +++----------- arch/arm/mach-shmobile/setup-sh73a0.c | 192 +++-------------- arch/sh/kernel/cpu/sh2/setup-sh7619.c | 27 ++- arch/sh/kernel/cpu/sh2a/setup-mxg.c | 9 +- arch/sh/kernel/cpu/sh2a/setup-sh7201.c | 72 +++++-- arch/sh/kernel/cpu/sh2a/setup-sh7203.c | 36 +++- arch/sh/kernel/cpu/sh2a/setup-sh7206.c | 36 +++- arch/sh/kernel/cpu/sh2a/setup-sh7264.c | 96 +++++++-- arch/sh/kernel/cpu/sh2a/setup-sh7269.c | 96 +++++++-- arch/sh/kernel/cpu/sh3/setup-sh7705.c | 18 +- arch/sh/kernel/cpu/sh3/setup-sh770x.c | 27 ++- arch/sh/kernel/cpu/sh3/setup-sh7710.c | 18 +- arch/sh/kernel/cpu/sh3/setup-sh7720.c | 18 +- arch/sh/kernel/cpu/sh4/setup-sh4-202.c | 15 +- arch/sh/kernel/cpu/sh4/setup-sh7750.c | 18 +- arch/sh/kernel/cpu/sh4/setup-sh7760.c | 58 +++-- arch/sh/kernel/cpu/sh4a/setup-sh7343.c | 36 +++- arch/sh/kernel/cpu/sh4a/setup-sh7366.c | 9 +- arch/sh/kernel/cpu/sh4a/setup-sh7722.c | 27 ++- arch/sh/kernel/cpu/sh4a/setup-sh7723.c | 54 +++-- arch/sh/kernel/cpu/sh4a/setup-sh7724.c | 54 +++-- arch/sh/kernel/cpu/sh4a/setup-sh7734.c | 66 ++++-- arch/sh/kernel/cpu/sh4a/setup-sh7757.c | 27 ++- arch/sh/kernel/cpu/sh4a/setup-sh7763.c | 27 ++- arch/sh/kernel/cpu/sh4a/setup-sh7770.c | 90 ++++++-- arch/sh/kernel/cpu/sh4a/setup-sh7780.c | 18 +- arch/sh/kernel/cpu/sh4a/setup-sh7785.c | 54 +++-- arch/sh/kernel/cpu/sh4a/setup-sh7786.c | 82 +++++-- arch/sh/kernel/cpu/sh4a/setup-shx3.c | 45 ++-- arch/sh/kernel/cpu/sh5/setup-sh5.c | 11 +- drivers/tty/serial/sh-sci.c | 238 ++++++++++++++++----- include/linux/serial_sci.h | 35 +-- 40 files changed, 1443 insertions(+), 1114 deletions(-) create mode 100644 Documentation/devicetree/bindings/serial/renesas,sci-serial.txt -- Regards, Laurent Pinchart -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
