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

[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:
https://lore.kernel.org/all/20220121074508.42168-5-liang.yang@amlogic.com
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

-Amlogic NAND Flash Controller (NFC) for GXBB/GXL/AXG family SoCs
-
-This file documents the properties in addition to those available in
-the MTD NAND bindings.
-
-Required properties:
-- compatible : contains one of:
-  - "amlogic,meson-gxl-nfc"
-  - "amlogic,meson-axg-nfc"
-
-- reg        : Offset and length of the register set
-
-- reg-names  : "nfc" is the register set for NFC controller and "emmc"
-		is the register set for MCI controller.
-
-- clocks     :
-	A list of phandle + clock-specifier pairs for the clocks listed
-	in clock-names.
-
-- clock-names: Should contain the following:
-	"core" - NFC module gate clock
-	"device" - parent clock for internal NFC
-
-Optional children nodes:
-Children nodes represent the available nand chips.

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

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:
https://lore.kernel.org/all/20220121074508.42168-5-liang.yang@amlogic.com
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]

 - split the nfc driver patch into two patches, one for fixing 
   clock, the other for refining the get nfc resource.

   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
