Hello, This is the fourth 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) and a Koelsch board (r8a7791-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. The series will need to be split in three parts to go to mainline. Patches 01/29 to 07/29 should go through Greg's tree, patches 08/29 to 26/29 through Simon's tree, and patches 27/29 to 29/29 through Greg's tree again. Simon will need a stable branch with the first seven patches, and should in turn provide a stable branch to base the last three patches on. Alternatively the whole series could go through Simon's tree. Greg, would that be fine with you ? The patches that would go through your tree touch drivers/tty/serial/sh-sci.c, include/linux/serial_sci.h and Documentation/devicetree/bindings/serial/renesas,sci-serial.txt only. There should be no risk of conflict if Simon takes all the sh-sci patches for the next kernel version. Changes compared to v3: - Rebased on top of renesas-devel-v3.13-rc1-20131125 Changes compared to v2: - Fix indentation in 12/29 - Remove interrupt-parent property from the DT bindings documentation - Remove -generic suffix from DT compatible values - Reword the DT bindings documentation based on comments received on v2 - Added r8a7791 support to the DT bindings 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@vger.kernel.org Cc: Greg KH <g...@kroah.com> Cc: Simon Horman <ho...@verge.net.au> 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 | 46 ++++ 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, 1447 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 majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
