[PATCH 0/9] v4.8 build regressions

[Arnd Bergmann]

This is a set of patches to address build warnings and errors that have
come up in linux-4.8 but that worked fine in v4.7. I've added the
tinyconfig warning patch in there as well, which is not a regression
but is something that shows up in the kernelci.org build bots.
The other patches address issues that either came up in kernelci.org
or in my randconfig test setup.

I have three more fixes queued up in arm-soc/fixes that I plan
to send as a pull request for -rc2 along with the other bugfixes.

All patches have been posted before, but for some reason or another
failed to make it into the merge window. I have updated the ones
that were waiting for a new version from me now, the others are
sent without modifications.

Hopefully we can get them all merged into v4.8. Please pick up
patches from the middle of the series if appropriate.

[PATCH 3/9] drm/mediatek: add COMMON_CLK dependency

[Arnd Bergmann]

On kernel builds without COMMON_CLK, the newly added mediatek drm
driver fails to build:

drivers/gpu/drm/mediatek/mtk_mipi_tx.c:130:16: error: field 'pll_hw' has incomplete type
  struct clk_hw pll_hw;
                ^~~~~~

This adds the required Kconfig dependency.

[PATCH 4/9] drm/mediatek: add CONFIG_OF dependency

[Arnd Bergmann]

The mediatek DRM driver can be configured for compile testing with
CONFIG_OF disabled, but then fails to link:

drivers/gpu/built-in.o: In function `mtk_drm_bind':
analogix_dp_reg.c:(.text+0x52888): undefined reference to `of_find_device_by_node'
analogix_dp_reg.c:(.text+0x52930): undefined reference to `of_find_device_by_node'

This adds an explicit Kconfig dependency.

[PATCH 5/9] drm/mediatek: add ARM_SMCCC dependency

[Arnd Bergmann]

ARM SMCCC is only set for ARMv7 and ARMv8 CPUs, but we currently
allow the driver to be build for older architecture levels as
well, which results in a link failure:

drivers/gpu/built-in.o: In function `mtk_hdmi_hw_make_reg_writable':
:(.text+0x1e737c): undefined reference to `arm_smccc_smc'

This adds a Kconfig dependency. The patch applies on my two
previous fixes that are not yet applied, so please apply all
three to get randconfig builds to work correctly.

Sent first on June 27 when it first broke in linux-next.
Two other dependencies were already missing, so I'm sending
all three patches again now.

I have picked up the three drm/mediatek patches.
