[PATCH v1 0/5] add support for Apalis iMX8 1300MHz version

[Stefan Eichenberger]

This patch series adds support for the Apalis iMX8, which utilizes the
industrial 1300MHz version of the iMX8 SoC. Additionally, it includes
minor cleanups that do not affect functionality.

First, the series adds support for the new Product IDs (PIDs) found in
the configuration block of the Apalis iMX8. The primary difference is
that this version uses the industrial SoC, which features lower CPU and
GPU frequencies compared to the automotive variant we used before.

Second, the series extends support to this new SoC. During testing, we
observed that the cpufreq driver did not account for the reduced CPU
frequencies, despite enforcement by the System Controller Firmware
(SCFW). This mismatch led to discrepancies between the frequencies
reported by the cpufreq driver and those actually set. We have also
updated the GPU to operate at the correct frequencies, as the SCFW does
not enforce these limits. Previously, this caused the GPU to overclock
to an unsupported frequency, as documented in the datasheet "i.MX
8QuadMax Industrial Applications Processors" (IMX8QMIEC).

This patch series depends on the following patch and should be merged
only after it has been applied:
