[PATCH v2 0/5] ARM: i.MX8MP: add nominal drive mode support

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

Unlike the i.MX8MM and i.MX8MN SoCs added earlier, the early setup code
and device tree for the i.MX8MP configures some clocks at frequencies
that are only validated for overdrive mode, i.e. when VDD_SOC is 950 mV.

Boards may want to run their SoC at the lower voltage of 850 mV though
to reduce heat generation and power usage. For this to work, clock rates
need to adhere to the limits of the nominal drive mode.

This needs to be done across both barebox and Linux. This series handles
the barebox side and a separate series will follow for the kernel.

Ahmad Fatoum (5):
  ARM: i.MX8M: pass cpu_type parameter to __imx8m_early_clock_init
  ARM: i.MX8MP: configure PLL3 as 600MHz
  ARM: i.MX8MP: configure PLL3 as noc_io parent
  ARM: i.MX8MP: don't reparent GIC from BootROM default
  ARM: dts: i.MX8MP: Add optional nominal drive mode DTSI
