First off, the clock frequency in the binding for the dgt is wrong. Software divides down the input rate by 4 to achieve the rate listed in the binding. We also treat each individual timer as a separate hardware component, when in reality there is one timer block (that may be duplicated per cpu) with multiple timers within it. Depending on the version of the hardware there can be one or two general purpose timers, status and divider control registers, and an entirely different register layout. In the next patch we'll need to know about the different register layouts so that we can properly check the status register after clearing the count. The current binding makes this complicated because the general purpose timer's reg property doesn't indicate where that status register is, and in fact it is beyond the size of the reg property. Clean all this up by just having one node for the timer hardware, and describe all the interrupts and clock frequencies supported while having one reg property that covers the entire timer register region. We'll use the compatible field in the future to determine different register layouts and if we should read the status registers, etc. Signed-off-by: Stephen Boyd Signed-off-by: David Brown --- .../devicetree/bindings/arm/msm/timer.txt | 41 +++++----- arch/arm/boot/dts/msm8660-surf.dts | 20 ++--- arch/arm/boot/dts/msm8960-cdp.dts | 22 ++---- arch/arm/mach-msm/timer.c | 79 ++++++++----------- 4 files changed, 68 insertions(+), 94 deletions(-) diff --git a/Documentation/devicetree/bindings/arm/msm/timer.txt b/Documentation/devicetree/bindings/arm/msm/timer.txt index 8c5907b9cae8..c6ef8f13dc7e 100644 --- a/Documentation/devicetree/bindings/arm/msm/timer.txt +++ b/Documentation/devicetree/bindings/arm/msm/timer.txt @@ -3,36 +3,35 @@ Properties: - compatible : Should at least contain "qcom,msm-timer".

To simplify this patch, remove the timer register setup done during timer init, since it's duplicate work that is eventually done in the set_next_event() callback.

But there's no corresponding Kconfig symbol, so this test will always evaluate to false. That Kconfig symbol is not needed because, as __arch_decomp_setup() shows, there are no DaVinci DA8XX boards that use UART0 for debugging. We can remove two lines of unneeded code.

Regulator constraints are added as per da850 board file. Regulator names are given as per maximum output voltage the regulator is capable to provide. for e.g. regulator name for dcdc1 is "VDCDC1_3.3V". Also, add tps6507x PMIC I2C slave device under I2C0 node. Tested on da850-evm.
