Subject[PATCH v2 0/5] ARM: multi_v7_defconfig: Improve rockchip support
Message-ID<qcd2x-1KY-3@gated-at.bofh.it>
Enable options to provide more complete support for Rockchip boards
including: support for the common PMICs, common RTC chips, I2C, SPI,
PMW, Thermal driver, HDMI video output and USB 2.

In response to V1 there was some direct and indirect discussion about
what policy to use for deciding what to build as a module versus what to
build in. Unfortunately there doesn't seem to be any consensus in this
regard, so for this series i've stuck to the following guideline for doing
things as builtin:
* If it's needed for booting without an initramfs to an NFS root
  filesystem.
* It's needed to prevent potential damage to the SoC

This results in building in various regulators (required by the
network driver), I2C bus (to control said regulators) and the thermal
driver (to prevent thermal damage). While everything else is a module.

Fwiw, I really don't have a strong opinion myself on whether this is a
better guideline then "Built-in only the bare minimum, people can use an
initramfs to load modules as needed" which e.g. Thierry has been
advocating. However it would be nice if we could get some common
guideline from e.g. the arm-soc maintainers as the typical "module or
not" discussion that tends to happen gets rather boring rather quickly:)


Changes in v2:
- Enable all common rockchip regulators, not just ACT8846
- Only enable the USB 2 phy, not the controller as that came in through
  another tree
- Enable USB 2.0 phy as a module as the controller is a module as well
- New patch, enable common RTC drivers

Rockchip boards seem to have two common regulator setups. Various board
used the Active Semi act8846 often in combination with Silergy syr82x
regulators (e.g. Radxa Rock Pro/Rock 2, Firefly, and Netxeon R89 etc),
while others use regulator part of the Rockchip RK808 chip (e.g. the
various Veyron based chromebooks, Chipspark Popmetal etc)

Enable all these regulators.

For people just skimming over these patches, the syr82x are siblings to the 
fan53555 - same register interface and all, thus that option gets enabled.

Similar to the power management situation on Rockchip boards, there are
two common RTC setups. For boards using the RK808 chip as a PMIC that
chip also serves as the RTC, while boards using the ACT8846 typically use
the Haoyu Microelectronics HYM8563 chip as their RTC.

Enable options needed for HDMI out on rockchip: DRM driver, Rockchip
DesignWare HDMI glue and the rockchip IOMMU (dependency of the DRM
driver).

As these patches are supposed to go through arm-soc directly and options 
getting enabled + the whole what gets set as built-in vs. module looks sane to 
me, I'll just provide for the whole series a:
