pm8941 is missing the 5vs2 regulator node so let's add it since its
needed to get the external display working. This regulator was already
configured in the interrupts property on the parent node.
Note that this regulator is referred to as mvs2 in the downstream MSM
kernel sources.
When attempting to configure this driver on a Nexus 5 phone (msm8974),
setting up the dummy i2c bus for TX_P0 would fail due to an -EBUSY
error. The downstream MSM kernel sources [1] shows that the proper value
for TX_P0 is 0x78, not 0x70, so correct the value to allow device
probing to succeed.
Add HDMI nodes and other supporting infrastructure in order to support
the external display. This is based on work from Jonathan Marek.

This is a replacement for a previous patches[1] that was adding arm64
support for drm_clflush. I've also added a patch to solve a similar
cache issue in vgem.
The first few patches just export arch_sync_dma_for_*(). Possibly
instead the EXPORT_SYMBOL_GPL() should be somewere
Add support for the avdd33 regulator to the analogix-anx78xx driver.
Note that the regulator is currently enabled during driver probe and
disabled when the driver is removed. This is currently how the
downstream MSM kernel sources do this.
Let's not merge this upstream for the mean time until I
This patch series begins to add support for the external display over
HDMI that is supported on msm8974 SoCs. I'm testing this series on the
Nexus 5, and I'm able to communicate with the HDMI bridge via the
analogix-anx78xx driver, however the external display is not working
yet.
When I plug in
The i2c_new_dummy() function is deprecated since it returns NULL on
error. Change this to use the recommended replacement
i2c_new_dummy_device() that returns an error code that can be read with
PTR_ERR() and friends.

was missing support for the 7812 and 7818 variants, so add them as well.

Use arch_sync_dma_for_{device,cpu}() rather than abusing the DMA API to
indirectly get at the arch_sync_dma code.
