[PATCH 0/6] MIPS: Mobileye: EyeQ5: add GPIO/I2C devicetrees/defconfigs

[Théo Lebrun]

Here we push changes to have GPIO and I2C support by default in EyeQ5
defconfigs and devicetrees.

Linux driver work has been pushed in the past. Devicetree patches
accompanied those series but didn't get merged at that time. Acked-by
on I2C DTS patches come from there.

We start by a small new defconfig patch that a clean working tree after:

   ⟩ make eyeq5_defconfig && \
     make savedefconfig   && \
     mv defconfig arch/mips/configs/eyeq5_defconfig

I2C DTS patches:
https://lore.kernel.org/lkml/20240306-mbly-i2c-v3-0-605f866aa4ec@bootlin.com/

[PATCH 1/6] MIPS: eyeq5_defconfig: Update for v6.16-rc1

[Théo Lebrun]

 - Sort by moving CONFIG_PAGE_SIZE_16KB=y.

 - Drop CONFIG_MACH_EYEQ5=y because it is the default:

      # arch/mips/mobileye/Kconfig
      choice
         prompt "Mobileye EyeQ SoC selection"
         default MACH_EYEQ5

 - Drop CONFIG_SPARSEMEM_MANUAL=y because:

      # mm/Kconfig
      choice
         prompt "Memory model"
         depends on SELECT_MEMORY_MODEL
         default SPARSEMEM_MANUAL if ARCH_SPARSEMEM_DEFAULT
         default FLATMEM_MANUAL

      # arch/mips/Kconfig
      config EYEQ
         select ARCH_SPARSEMEM_DEFAULT if 64BIT

[PATCH 2/6] MIPS: mobileye: eyeq5: add 5 I2C controller nodes

[Théo Lebrun]

Add the SoC I2C controller nodes to the platform devicetree. Use a
default bus frequency of 400kHz. They are AMBA devices that are matched
on PeriphID.

Set transfer timeout to 10ms instead of Linux's default of 200ms.

[PATCH 4/6] MIPS: mobileye: eyeq5: add two GPIO bank nodes

[Théo Lebrun]

This platform uses the same GPIO controller as Nomadik. It however has
its own pinconf & pinmux controller. EyeQ5 is the first platform to use
gpio-nomadik independently from pinctrl-nomadik.
