ARM: tegra: apalis-tk1: move hdmi ddc config to dt

2017-10-04T23:10:42+00:00

We moved HDMI DDC configuration to the device-tree.
If DDC config is missing from the device-tree
we default to v1.2 config.

ARM: tegra: apalis-tk1: support v1.2 hardware revision

2017-10-03T14:35:28+00:00

Support the V1.2 hardware revision with the following pin muxing
changes:

Ddc_scl_pv4 and ddc_sda_pv5 previously used as Apalis GPIO3 and GPIO4
are now used as DDC pins.

Gen2_i2c_scl_pt5 and gen2_i2c_sda_pt6 previously used as DDC pins are
now used as USB power enable signals.

Usb_vbus_en0_pn4 and usb_vbus_en1_pn5 previously used as USB power
enable signals are now used as GPIO3 and GPIO4.

ARM: tegra: Select appropriate DMA options for LPAE

2017-09-27T20:45:24+00:00

This automatically selects options for zone DMA and 64 bit DMA addresses
when LPAE is enabled on ARM Tegra platforms. These options are required
for proper operation with LPAE enabled.

The ZONE_DMA option is required to ensure that drivers that allocate DMA
memory get buffers from the first 4 GiB. This is necessary because a lot
of the controllers only support addressing 32 bits.

As for ARCH_DMA_ADDR_T_64BIT, there are situations where devices that do
support addresses of more than 32 bits (such as the display controller
or the GPU) can run without translating addresses through an IOMMU on a
device with more than 4 GiB of system memory.

Note that both of these options are stop-gap solutions required only
until the IOMMU can be properly integrated with the DMA mapping API and
drivers use that properly and consistently.
