167efc2c7a arm64: dts: rk3399: Sync v5.7-rc1 from Linux
Sync rk3399 dts(i) files from v5.7-rc1 linux-next.

Reason:
To get updated PCIe nodes and properties on respective
dts(i) files.

Summary:
- sync won't include new board dts(i)
- sync will add required files used on respective dts(i)
- rk3399-puma-u-boot.dtsi spiflash label changed to norflash
- move puma.dtsi bios_enable into rk3399-puma-u-boot.dtsi
- move legacy max-frequency of sdhci into rk3399-u-boot.dtsi
- update cross-ec-[keyboard|sbs].dtsi path as per U-Boot
- keep roc-rk3399-pc dc_12v changes to -u-boot.dtsi

96993d7c35 clk: rk3399: Set empty for HCLK_SD assigned-clocks
Due to v5.7-rc1 sync the SD controller nodes in rk3399.dtsi
have HCLK_SD assigned-clocks which are usually required for
Linux and don't require to handle them in U-Boot.

 assigned-clocks = <&cru HCLK_SD>;

So, mark them as empty in clock otherwise device probe on
those SD controllers would fail.

062baa2566 rockchip: dts: rock64: Fix XHCI usage

bab972948e rockchip: rk3328: Add support for ROC-RK3328-CC board
The ROC-RK3328-CC from Firefly and Libre Computer Project is a credit
card size development board based on the Rockchip RK3328 SoC, with:

  - 1/2/4 GB DDR4 DRAM
  - eMMC connector for optional module
  - micro SD card slot
  - 1 x USB 3.0 host port
  - 2 x USB 2.0 host port
  - 1 x USB 2.0 OTG port
  - HDMI video output
  - TRRS connector with audio and composite video output
  - gigabit Ethernet
  - consumer IR receiver
  - debug UART pins

The ROC-RK3328-CC has the enable pin of the SD card power switch tied
to GPIO_0_D6. This pin also has the function SDMMC0_PWREN, which is
muxed by default. SDMMC0_PWREN is an active high signal controlled by
the MMC controller, however the switch enable is active low, and
pulled low (enabled) by default to make things work on boot.

As such, we need to mux away from SDMMC0_PWREN and use GPIO to enable
power to the card. The default GPIO state for the pin is pull-down and
input, which doesn't require extra configuration when paired with the
external pull-down and active low switch.

Deal with this by enabling regulator support in SPL, and setting
"u-boot,dm-spl" for the regulator and other device nodes needed for
muxing the pin.

The device tree file is synced from the Linux kernel next-20200324.

50cbff7cf3 rockchip: dts: rk3328: Sync device tree files from Linux
This syncs rk3328 device tree files from the Linux kernel next-20200324.
The last commit to touch these files is:

    b2411befed60 ("arm64: dts: add bus to rockchip amba nodenames")

Additional changes not yet in the Linux kernel include:

    arm64: dts: rockchip: rk3328: drop #address-cells, #size-cells from grf node
    arm64: dts: rockchip: rk3328: drop non-existent gmac2phy pinmux options
    arm64: dts: rockchip: rk3328: Replace RK805 PMIC node name with "pmic"

Changes include:

  - conversion of raw pin numbers to macros
  - removal of deprecated RK_FUNC_* macros
  - update of device tree binding headers
  - new devices
  - device tree cleanups
  - gmac2phy disabled in -u-boot.dtsi as it is not supported in U-boot

This includes a re-ordering of the USB device nodes compared to upstream
Linux, moving the dwc2 OTG controller after the EHCI/OHCI nodes. This is
currently required as otherwise the dwc2 controller would not be able to
detect devices in some cases. This may be due to lack of USB PHY support
in U-boot.

5d0ec90ac8 rockchip: rk3328: Disable generic PHY support
The USB PHYs on the RK3328 aren't supported, nor are any other generic
PHYs. Because upstream Linux device trees already include the USB PHYs
and references in the USB hosts, this would result in various calls
to the generic PHY API to fail.

Instead, just disable generic PHY support for now.

c11f0d88ba coccinelle: adjust NULL check before free()
The free() function checks if its argument is NULL. We should avoid
checking for NULL before calling free like in

    if (result->tds)
        free(result->tds);

The list of relevant functions differs between Linux and U-Boot, e.g. we
use free().

Adjust the list of relevant functions.

cb2a2ebd4f coccinelle: check for casting malloc output
Casting the (void *) output of memory allocation functions before
assignment like in

	sata->cmd_hdr_tbl_offset = (void *)malloc(length + align);

is useless.

Adopt the Linux kernel script
scripts/coccinelle/api/alloc/alloc_cast.cocci.

Now 'make coccicheck' generates warnings like:

./drivers/ata/fsl_sata.c:143:29-33:
WARNING: casting value returned by memory allocation function
to (void *) is useless.

c3da3f5808 kbuild: add FORCE to dependency of $(obj)/dts/dt-platdata.o
if_changed must have FORCE as a prerequisite.

Add $(obj)/dts/dt-platdata.o to 'targets' so that the corresponding
