Dear Maintainer,
Please enable a set of drivers requried for the layerscape based arm64
honeycomb board.
It is a mini-itx board for use as a workstation machine. Its support in
mainline is not complete yet,
but many bits are already functional.
I am attaching a patch for enabling the options I have found through reading
the dts from RMKs cex7 branch.
Changes were tested on 5.5-rc5 built from the debian kernel packaging tree.
Some drivers are currently enabled implicitly, i.e. not listed in either
debian/config/{,arm64/}config:
CONFIG_PTP_1588_CLOCK=m
CONFIG_I2C_MUX=m
CONFIG_SENSORS_LM90=m
CONFIG_RTC_DRV_PCF2127=m
CONFIG_ARM_GIC_V3_ITS_FSL_MC=y
^^ Not sure how you decide when to make options explicit, and when not ... so
these are *not* included in my attached patch!
The PCI Express driver is still pending inclusion in Linux:
https://patchwork.kernel.org/patch/11253015/
Once that lands, CONFIG_PCIE_LAYERSCAPE_GEN4=m should also be enabled.
Yours sincerely
Josua Mayer

Subject: [PATCH] enable support for the Honeycomb arm64 workstation
This enables support for the Layerscape architecture in general,
as well as
- drivers for the Soc listed in (fsl-lx2160a.dtsi)
- drivers for peripherals listed in (fsl-lx2160a-cex7.dtsi)
.
Some drivers are currently enabled implicitly, i.e. not listed in either
debian/config/{,arm64/}config:
CONFIG_PTP_1588_CLOCK=m
CONFIG_I2C_MUX=m
CONFIG_SENSORS_LM90=m
CONFIG_RTC_DRV_PCF2127=m
CONFIG_ARM_GIC_V3_ITS_FSL_MC=y
The PCI Express driver is still pending inclusion in Linux:
https://patchwork.kernel.org/patch/11253015/
Once that lands, CONFIG_PCIE_LAYERSCAPE_GEN4=m should also be enabled.
