[PATCH v8 1/5] pinctrl: Ingenic: Fix bugs in X1000 and X1500.

[周琰杰 (Zhou Yanjie)]

1.Fix the pullup parameter of X1000.
2.X1000 and X1500 have only one set of uart1 hwflow pin mapping,
  so modify "uart1_hwflow_d" to "uart1_hwflow".
3.X1000 has only one set of mmc1 pin mapping, so modify
  "mmc1-1bit-e/mmc1-4bit-e" to "mmc1-1bit/mmc1-4bit".
4.X1000 has only one regular externel memory controller that
  does not support nand flash, so change "nemc_" to "emc_".
5.X1500 has only one set of mmc, so modify "mmc0_" to "mmc_".

Notes:
    v1->v2:
    Modify "nemc_" to "emc_" because X1000 has only one regular externel
    memory controller that does not support nand flash.
    
    v2->v3:
    No change.
    
    v3->v4:
    No change.
    
    v4->v5:
    No change.
    
    v5->v6:
    No change.
    
    v6->v7:
    Change my Signed-off-by from "Zhou Yanjie <zhouyanjie@zoho.com>"
    to "周琰杰 (Zhou Yanjie) <zhouyanjie@wanyeetech.com>" because
    the old mailbox is in an unstable state.
    
    v7->v8:
    No change.

[PATCH v8 2/5] pinctrl: Ingenic: Add missing parts for X1000 and X1500.

[周琰杰 (Zhou Yanjie)]

1.Add pinctrl drivers for the SPI flash controller (SFC) of
  X1000 and X1500.
2.Add pinctrl driver for the synchronous serial interface (SSI)
  of X1000.

[PATCH v8 3/5] pinctrl: Ingenic: Introduce reg_offset and use it instead hard code.

[周琰杰 (Zhou Yanjie)]

Introduce "reg_offset", use it instead hard code "0x100",
it will also be used for subsequent X1830 pinctrl driver.

[PATCH v8 5/5] pinctrl: Ingenic: Add pinctrl driver for X1830.

    Add pinctrl drivers for the PWM of X1830.

      configured in HiZ mode.

    Fix compile-time warnings.
    Reported-by: kbuild test robot <lkp@intel.com>
    
    v5->v6:
    1.Use local variables to streamline code.

      the old mailbox is in an unstable state.
    2.Add "ingenic_chip_info.reg_offset", use it instead of having
      hardcoded, and add "PZ_BASE()" / "PZ_GID2LD()" macros, use it
      with "ingenic_chip_info.reg_offset" to simplify code related
      to shadow registers.
    3.Simplify the code of the "ingenic_set_bias" function.
