This series bring first part that adds the common MFD driver that provides an access to the bus that can be either I2C or SPI. The next part of the series is bringing the DPLL driver that will covers DPLL functionality. Another series will bring PTP driver and flashing capability via devlink in the MFD driver will follow soon. Testing was done by myself and by Prathosh Satish on Microchip EDS2 development board with ZL30732 DPLL chip connected over I2C bus. Patch breakdown =============== Patch 1 - Common DT schema for DPLL device and pin Patch 2 - DT bindings for microchip,zl3073* devices Patch 3 - Basic support for I2C, SPI and regmap configuration Patch 4 - Devlink device registration and info Patch 5 - Helpers for reading and writing register mailboxes Patch 6 - Fetch invariant register values used by DPLL/PTP sub-drivers Patch 7 - Clock ID generation for DPLL driver Patch 8 - Register/create DPLL device cells --- v4->v5: * fixed DT patches description * dropped mailbox API * added type-safe register access functions * added an ability to protect multi-op accesses v3->v4: * fixed shortcomings in DT patches * completely reworked register access * removed a need to manage locking during mailbox accesses by callers * regcache switched to maple * dev_err_probe() in probe path * static mfd cells during sub-devices registration v1->v3: * dropped macros for generating register access functions * register access functions are provided in * fixed DT descriptions and compatible wildcard usage * reworked regmap locking - regmap uses implicit locking - mailbox registers are additionally protected by extra mutex * fixed regmap virtual address range * added regmap rbtree cache (only for page selector now) * dropped patches for exporting strnchrnul and for supporting mfg file this will be maybe added later Ivan Vecera (8): dt-bindings: dpll: Add DPLL device and pin dt-bindings: dpll: Add support for Microchip Azurite chip family mfd: Add Microchip ZL3073x support mfd: zl3073x: Add support for devlink device info mfd: zl3073x: Protect operations requiring multiple register accesses mfd: zl3073x: Fetch invariants during probe mfd: zl3073x: Add clock_id field mfd: zl3073x: Register DPLL sub-device during init .../devicetree/bindings/dpll/dpll-device.yaml | 76 ++ .../devicetree/bindings/dpll/dpll-pin.yaml | 45 + .../bindings/dpll/microchip,zl30731.yaml | 115 +++ MAINTAINERS | 11 + drivers/mfd/Kconfig | 32 + drivers/mfd/Makefile | 5 + drivers/mfd/zl3073x-core.c | 855 ++++++++++++++++++ drivers/mfd/zl3073x-i2c.c | 68 ++ drivers/mfd/zl3073x-regs.h | 54 ++ drivers/mfd/zl3073x-spi.c | 68 ++ drivers/mfd/zl3073x.h | 31 + include/linux/mfd/zl3073x-regs.h | 88 ++ include/linux/mfd/zl3073x.h | 188 ++++ 13 files changed, 1636 insertions(+) create mode 100644 Documentation/devicetree/bindings/dpll/dpll-device.yaml create mode 100644 Documentation/devicetree/bindings/dpll/dpll-pin.yaml create mode 100644 Documentation/devicetree/bindings/dpll/microchip,zl30731.yaml create mode 100644 drivers/mfd/zl3073x-core.c create mode 100644 drivers/mfd/zl3073x-i2c.c create mode 100644 drivers/mfd/zl3073x-regs.h create mode 100644 drivers/mfd/zl3073x-spi.c create mode 100644 drivers/mfd/zl3073x.h create mode 100644 include/linux/mfd/zl3073x-regs.h create mode 100644 include/linux/mfd/zl3073x.h -- 2.49.0
