DT binding for the PWM block in Qualcomm IPQ6018 SoC.
Signed-off-by: Baruch Siach <baruch@xxxxxxxxxx>
---
This series does not convert the TCSR binding documentation to YAML. As
a result, this commit adds new a dt_binding_check warning:
/example-0/syscon@1937000: failed to match any schema with compatible: ['qcom,tcsr-ipq 6018', 'syscon', 'simple-mfd']
If that is a blocker to IPQ6018 PWM support, so be it. Patches will wait
for someone else to push them further.
v8:
Add size cell to 'reg' (Rob)
v7:
Use 'reg' instead of 'offset' (Rob)
Drop 'clock-names' and 'assigned-clock*' (Bjorn)
Use single cell address/size in example node (Bjorn)
Move '#pwm-cells' lower in example node (Bjorn)
List 'reg' as required
v6:
Device node is child of TCSR; remove phandle (Rob Herring)
Add assigned-clocks/assigned-clock-rates (Uwe Kleine-König)
v5: Use qcom,pwm-regs for phandle instead of direct regs (Bjorn
Andersson, Kathiravan T)
v4: Update the binding example node as well (Rob Herring's bot)
v3: s/qcom,pwm-ipq6018/qcom,ipq6018-pwm/ (Rob Herring)
v2: Make #pwm-cells const (Rob Herring)
