614a54cb5a pinctrl: sophgo: add support for SG2044 SoC 
SG2044 share the share common control logic with SG2042. So
only pin definition is needed.

Add pin definition driver for SG2044 SoC.

2a85188c2f pinctrl: sophgo: introduce generic probe function 
Since different series of the Sophgo chip share a common pinctrl data
structure. It is necessary to add a common probe function to alloc
the this data structure. Add pctrl_init callback to allow soc to perform
its own initialization.

96406fa941 pinctrl: sophgo: generalize shareable code of cv18xx pinctrl driver 
With generic data structure, it is possible to generalize vddio
operators and DT parsing code of cv18xx pinctrl driver. Introduce
sophgo_cfg_ops callback to allow the driver to adjust the soc
logic and share common code.

e096d3ada7 pinctrl: sophgo: introduce generic data structure for cv18xx pinctrl driver 
To share DT parsing and vddio code, it is necessary to introduce
some generic data structure to abstract the different cv18xx series
and the incoming sg2042 series.

ef1a5121ae pinctrl: sophgo: avoid to modify untouched bit when setting cv1800 pinconf 
When setting pinconf configuration for cv1800 SoC, the driver just writes
the value. It may zero some bits of the pinconf register and cause some
unexpected error. Add a mask to avoid this.

Pull pin control updates from Linus Walleij:
 "No core changes this time.

  New drivers:

   - Xlinix Versal pin control driver

   - Ocelot LAN969x pin control driver

   - T-Head TH1520 RISC-V SoC pin control driver

   - Qualcomm SM8750, IPQ5424, QCS8300, SAR2130P and QCS615 SoC pin
     control drivers

   - Qualcomm SM8750 LPASS (low power audio subsystem) pin control
     driver

   - Qualcomm PM8937 mixsig IC pin control support, GPIO and MPP
     (multi-purpose-pin)

   - Samsung Exynos8895 and Exynos9810 SoC pin control driver

   - SpacemiT K1 SoC pin control driver

   - Airhoa EN7581 IC pin control driver

4575962aee pinctrl: sophgo: fix double free in cv1800_pctrl_dt_node_to_map() 
'map' is allocated using devm_* which takes care of freeing the allocated
data, but in error paths there is a call to pinctrl_utils_free_map()
which also does kfree(map) which leads to a double free.

Use kcalloc() instead of devm_kcalloc() as freeing is manually handled.
