2022-10-17dt-bindings: hwlock: qcom-hwspinlock: add syscon to MSM8974Krzysztof Kozlowski1-1/+5
The TCSR_MUTEX region contains two set of registers: mutex and halt. Add syscon, so the TCSR mutex device (hwspinlock) can use MMIO based method and in the same time share regmap with other devices for the halt regs.

2022-09-13dt-bindings: hwlock: qcom-hwspinlock: add support for MMIO on older SoCsKrzysztof Kozlowski1-3/+12
Older Qualcomm SoCs have TCSR mutex registers with 0x80 stride, instead of 0x1000. Add dedicated compatibles for such case. Unfortunately the binding started using a generic "qcom,tcsr-mutex" compatible without specifying the SoC part, thus it looks now quite inconsistent.

2020-07-13dt-bindings: hwlock: qcom: Allow device on mmio busBjorn Andersson1-1/+15
In modern Qualcomm platforms the mutex region of the TCSR is forked off into its own block, all with a offset of 0 and stride of 4096, and in some of these platforms no other registers in this region is accessed from Linux. Update the binding to allow the hardware block to be described directly on the mmio bus, in addition to allowing the existing syscon based definition for backwards compatibility.

This patch adds the generic common bindings used to represent a hwlock device and use/request locks in a device-tree build. Each hwspinlock provider should have the '#hwlock-cells' property, which represents the number of cells to be used for representing a specific hwspinlock. Client users shall use the property 'hwlocks' for requesting specific lock(s). Note that the document is named hwlock.txt deliberately to keep it a bit more generic.
