ebeab0be70 arm64: dts: fsd: Add Ethernet support for PERIC Block of FSD SoC
The FSD SoC contains two instances of Synopsys DWC QoS Ethernet IP, one in
FSYS0 block and other in PERIC block.
The ethernet interface is connected to a switch which is not managed by
Linux.

Adds device tree node for Ethernet in PERIC Block and enables the same for
FSD platform.

7f62af80dc arm64: dts: fsd: Add I2S DAI node for Tesla FSD
Add device tree node for I2S0 and I2S1 CPU DAI instances for Tesla
FSD platform.

FSD SoC has 2 I2S instances driving stereo channel I2S audio playback
and capture with external DMA support.

32d0c06801 arm64: dts: fsd: fix PUD values as per FSD HW UM
PUD values used for UFS, SPI and UART are not reflecting
the default values recommended by FSD HW UM. Therefore,
changing the same to comply with HW UM recommendation.

574d6c59da arm64: dts: fsd: fix drive strength macros as per FSD HW UM
Drive strength macros defined for FSD platform is not reflecting actual
names and values as per HW UM. FSD SoC pinctrl has following four levels
of drive-strength and their corresponding values:
Level-1 <-> 0
Level-2 <-> 1
Level-4 <-> 2
Level-6 <-> 3

The commit 684dac402f ("arm64: dts: fsd: Add initial pinctrl support")
used drive strength macros defined for Exynos4 SoC family. For some IPs
the macros values of Exynos4 matched and worked well, but Exynos4 SoC
family drive-strength (names and values) is not exactly matching with
FSD SoC.

Fix the drive strength macros to reflect actual names and values given
in FSD HW UM.

5621638cf0 arm64: dts: fsd: use local header for pinctrl register values
The DTS uses hardware register values directly in pin controller pin
configuration.  These are not some IDs or other abstraction layer but
raw numbers used in the registers.

These numbers were previously put in the bindings header to avoid code
duplication and to provide some context meaning (name), but they do not
fit the purpose of bindings.  It is also quite confusing to use
constants prefixed with Exynos for other SoC, because there is actually
nothing here in common, except the actual value.

Store the constants in a header next to DTS and use them instead of
bindings.
