[PATCH RESEND v8 0/5] fix the meson NFC clock

[Liang Yang]

EMMC and NAND have the same clock control register named 'SD_EMMC_CLOCK'
which is defined in EMMC port internally. bit0~5 of 'SD_EMMC_CLOCK' is
the divider and bit6~7 is the mux for fix pll and xtal. At the beginning,
a common MMC and NAND sub-clock was discussed and planed to be implemented
as NFC clock provider, but now this series of patches of a common MMC and
NAND sub-clock are never being accepted and the current binding was never
valid. the reasons are:
1. EMMC and NAND, which are mutually exclusive anyway
2. coupling the EMMC and NAND.
3. it seems that a common MMC and NAND sub-clock is over engineered.
and let us see the link for more information:

so The meson nfc can't work now, let us rework the clock.

Changes since v7 [8]
 - use COMMON_CLK && (ARCH_MESON || COMPILE_TEST) instead of
   ARCH_MESON || COMPILE_TEST || COMMON_CLK.
 - collect the review and ack

Changes since v6 [7]
 - use COMMON_CLK instead of !HAVE_LEGACY_CLK

Changes since v5 [6]
 - add change log for patch 3/5
 - add patch 5/5 to fix the reporting error of test robot

Changes since v4 [5]
 - split the dt binding patch into two patches, one for fixing, 
   clock, the other for coverting to yaml
 - split the nfc driver patch into two patches, one for fixing 
   clock, the other for refining the get nfc resource.

Changes since v3 [4]
 - use devm_platform_ioremap_resource_byname
 - dt_binding_check for mtd/amlogic,meson-nand.yaml

Changes since v2 [3]
 - use fw_name from dts, instead the wrong way using __clk_get_name
 - reg resource size change to 0x800
 - use reg-names

Changes since v1 [2]
 - use clk_parent_data instead of parent_names
 - define a reg resource instead of sd_emmc_c_clkc
