Boris Brezillon 9a8b9434c6 phy: mediatek: Add missing MODULE_DEVICE_TABLE()
This patch adds the missing MODULE_DEVICE_TABLE definitions on different
Mediatek phy drivers which generates correct modalias for automatic loading
when these drivers are compiled as an external module.

Arnd Bergmann d092bd9110 phy: mediatek: allow compile-testing the dsi phy
Randconfig builds show another broken dependency:

WARNING: unmet direct dependencies detected for PHY_MTK_MIPI_DSI
  Depends on [n]: ARCH_MEDIATEK [=n] && OF [=y]
  Selected by [m]:
  - DRM_MEDIATEK [=m] && HAS_IOMEM [=y] && DRM [=m] && (ARCH_MEDIATEK [=n] || ARM [=y] && COMPILE_TEST [=y]) && COMMON_CLK [=y] &&

This is similar to the hdmi driver I fixed earlier, and I guess the
common-clk bug would sooner or later also manifest here, so just use
the exact same solution I chose for the other driver, and hope that
any future drivers just copy it from here.

Colin Ian King b097efba95 drm/mediatek: avoid dereferencing a null hdmi_phy on an error message
Currently there is a null pointer check for hdmi_phy that implies it
may be null, however a dev_err messages dereferences this potential null
pointer.  Avoid a null pointer dereference by only emitting the dev_err
message if hdmi_phy is non-null.  It is a moot point if the error message
needs to be printed at all, but since this is a relatively new piece of
code it may be useful to keep the message in for the moment in case there
are unforseen errors that need to be reported.

Arnd Bergmann f5f6e01f91 phy: mediatek: allow compile-testing the hdmi phy
Compile-testing the DRM_MEDIATEK_HDMI driver shows two missing

The other one is a harmless warning:

  Selected by [y]:
  - DRM_MEDIATEK_HDMI [=y] && HAS_IOMEM [=y] && DRM_MEDIATEK [=y]

Fix these by adding dependencies on CONFIG_OF and CONFIG_COMMON_CLK.
With that done, there is also no reason against adding
CONFIG_COMPILE_TEST.

devm_ioremap_resource() will be not built in lib/devres.c if
CONFIG_HAS_IOMEM is not set, of_address_to_resource() will be
not built in drivers/of/address.c if CONFIG_OF_ADDRESS is not
set, and then there exists two build errors about undefined
reference to "devm_ioremap_resource" and "of_address_to_resource"
in phy-mtk-xsphy.c under COMPILE_TEST and CONFIG_PHY_MTK_XSPHY,
make PHY_MTK_XSPHY depend on HAS_IOMEM and OF_ADDRESS to fix it.

The above issue is reported by kernel test robot <lkp@intel.com>,
through the discussion in the v1 patch, as Chunfeng said we need
also do this for config PHY_MTK_TPHY:

chunhui dai 09e872d558 drm/mediatek: Disable tmds on mt2701
Without that patch if you use specific resolutions like 1280x1024,
I can see distortion in the output. It seems as if the
frequency for updating the pixel of the image is out of sync.

For initialization tmds needs to be active, but can be disabled after init
to fix blurry display

CK Hu b28be59a2e phy: mediatek: Move mtk_hdmi_phy driver into drivers/phy/mediatek folder
mtk_hdmi_phy is currently placed inside mediatek drm driver, but it's
more suitable to place a phy driver into phy driver folder, so move
mtk_hdmi_phy driver into phy driver folder.

Chunfeng Yun 12d0c0bed3 phy: phy-mtk-tphy: add a new reference clock
Usually the digital and analog phys use the same reference clock,
but some platforms have two separate reference clocks for each of
them, so add another optional clock to support them.
In order to keep the clock names consistent with PHY IP's, change
the da_ref for analog phy and ref clock for digital phy.
