Hi Simon, Thanks for the patch. Could you please CC LKML on this one ? It targets a wider audience than the SH-specific patches.

this is a third pass at at providing a refernce DT implementation for the kzm9g baord which is intended to act as a guide for mach-shmobile developers. It provides a minimal setup of the board using as little C code as possible. It may be used by selecting CONFIG_MACH_KZM9G_REFERENCE and using sh73a0-kzm9g-reference.dtb *** Please note that the clock initialisation shcheme used in this series does not currently work with SMP as there is a yet to be resolved lock-up in workqueue initialisation. Resolving this problem is currently regarded as future-work. CONFIG_SMP must be disabled when using this code. *** Major difference between v2 and v3: * Allow UP boot to complete by initialiing CMT earlier. This is achieved by changing the position of clocsources/ in drivers/Makefile Major difference between v1 and v2: * Drop touchscreen initialisation, it requires INTC * Drop SDHI initialisation, the driver seems to need some work * Add extra entries to clock-sh73a0.c:lookups[] and remove auxdata. Ultimtely the clocks will be described in DT, but the code isn't there yet. * Drop MMCIF patch, it is not needed if regulators are enabled * Drop PCF hacks, instead, the series is based on Laruent Pinchart's * * series: [PATCH v2 00/77] SH pin control and GPIO rework with OF support * Use shmobile_setup_delay() Git and diffstat information provided to aid review. ---------------------------------------------------------------- The following changes since commit 940956fe1d8de5cbcc963214fe592f76d8354bef: ARM: shmobile: kzm9g: Add LED1-LED4 to the device tree (2012-11-27 00:59:10 +0100) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas.git devel/of-kzm9g for you to fetch changes up to e64ad872028f921a7a30be325fbdecc725958b40: ARM: mach-shmobile: kzm9g: Reference DT implementation (2012-12-11 11:51:56 +0900) ---------------------------------------------------------------- Simon Horman (6): ARM: clocksource: Initialise early ARM: mach-shmobile: sh73a0: Allow initialisation of GIC by DT ARM: mach-shmobile: sh73a0: Minimal setup using DT ARM: mach-shmobile: sh73a0: Initialise MMCIF using DT ARM: mach-shmobile: kzm9g: use voltage regulators by default ARM: mach-shmobile: kzm9g: Reference DT implementation arch/arm/boot/dts/Makefile | 3 +- arch/arm/boot/dts/sh73a0-kzm9g-reference.dts | 37 +++++++++ arch/arm/boot/dts/sh73a0-reference.dtsi | 24 ++++++ arch/arm/boot/dts/sh73a0.dtsi | 69 +++++++++++++++++ arch/arm/configs/kzm9g_defconfig | 2 + arch/arm/mach-shmobile/Kconfig | 10 +++ arch/arm/mach-shmobile/Makefile | 1 + arch/arm/mach-shmobile/board-kzm9g-reference.c | 99 ++++++++++++++++++++++++ arch/arm/mach-shmobile/clock-sh73a0.c | 13 ++++ arch/arm/mach-shmobile/include/mach/common.h | 3 + arch/arm/mach-shmobile/intc-sh73a0.c | 14 ++++ arch/arm/mach-shmobile/setup-sh73a0.c | 68 +++++++++++++++- drivers/Makefile | 8 +- 13 files changed, 346 insertions(+), 5 deletions(-) create mode 100644 arch/arm/boot/dts/sh73a0-kzm9g-reference.dts create mode 100644 arch/arm/boot/dts/sh73a0-reference.dtsi create mode 100644 arch/arm/mach-shmobile/board-kzm9g-reference.c
