Add device tree for the Libra-i.MX 95 FPSC board. The Libra is a
pure development board and has hardware to support FPSC-24-A.0 set of
features. The phyCORE-i.MX 95 FPSC [1] SoM uses only a subset of
the hardware features of the Libra board. The phyCORE-i.MX 95 FPSC
itself is a System on Module designed around the i.MX 95 SoC.
The SoM and board utilize the Future Proof Solder Core [2] BGA standard
to connect to each other.
To be able to easily map FPSC interface names to SoC interfaces, the
FPSC interface names are added as inline comments. Example:
&lpi2c5 { /* I2C2 */
pinctrl-0 = <&pinctrl_lpi2c5>;
[...]
};
Here, I2C2 is the FPSC interface name. The lpi2c5 instance of the i.MX 95
SoC is used to fulfill the i2c functionality and its signals are routed
to the FPSC I2C2 signal pins:
pinctrl_lpi2c5: lpi2c5grp {
fsl,pins = <
IMX95_PAD_GPIO_IO22__LPI2C5_SDA 0x40000b9e /* I2C2_SDA */
IMX95_PAD_GPIO_IO23__LPI2C5_SCL 0x40000b9e /* I2C2_SCL */
>;

The defaults for this SoC are configured for overdrive mode, but
the VPU clocks are currently configured for nominal mode.
Increase VPU_G1_CLK_ROOT to 800MHZ from 600MHz,
Increase VPU_G2_CLK_ROOT to 700MHZ from 500MHz, and
Increase VPU_BUS_CLK_ROOT to 800MHz from 600MHz.
This requires adjusting the clock parents. Since there is already
800MHz clock references, move the VPU_BUS and G1 clocks to it.
This frees up the VPU_PLL to be configured at 700MHz to run
the G2 clock at 700MHz.

devm_of_platform_populate() passes a NULL as the bus OF match table
to the underlying of_platform_populate(), meaning child bus devices
of the AIPSTZ bridge will not have its children devices created. Since
some SoCs (e.g. i.MX8MP) use this particular setup (e.g. SPBA bus, which
is a child of AIPSTZ5 and has multiple child nodes), the driver needs to
support it.
Therefore, replace devm_of_platform_populate() with of_platform_populate()
and pass a reference to the bus OF match table to it. For now, the only
possible child buses are simple buses.
Since the usage of devres is dropped, the complementary operation of
of_platform_populate() needs to be called during the driver's removal.
