drm/tegra: sor: Operate on struct drm_dp_aux *

2015-12-14T09:50:37Z

Instead of getting a pointer to the driver-specific wrapper of AUX channels, use the AUX channel objects directly to avoid hackish casting between the two types. Signed-off-by: Thierry Reding

drm/tegra: Handle I2C_WRITE_STATUS_UPDATE for address only writes

2015-09-08T18:15:42Z

A address-only I2C_WRITE can't be replied with a short i2c ack, but I suppose it could be replied with an i2c defer. So the code should be prepared for an address-only I2C_WRITE_STATUS_UPDATE.

drm/dp: s/I2C_STATUS/I2C_WRITE_STATUS_UPDATE/

2015-09-08T18:12:38Z

Rename the I2C_STATUS request to I2C_WRITE_STATUS_UPDATE to match the spec. Acked-by: Alex Deucher Reviewed-by: Jani Nikula Signed-off-by: Ville Syrjälä Signed-off-by: Daniel Vetter

drm/tegra: dpaux: Disable interrupt when detached

2015-08-13T11:47:49Z

When the DPAUX isn't attached to an SOR the interrupts are not useful. This also prevents a race that could potentially cause a crash on driver removal. Signed-off-by: Thierry Reding

drm/tegra: dpaux: Configure pads as I2C by default

2015-08-13T11:47:47Z

The DPAUX code paths already configure the pads in AUX mode, but there is no way to reconfigure them in I2C mode for HDMI (the DPAUX module is unused in that case). Enabling the pads in I2C mode by default is the quickest way to support HDMI. Eventually this may need an explicit call in the user drivers. Signed-off-by: Thierry Reding

drm/tegra: dpaux: Provide error message in probe

2015-08-13T11:47:46Z

When probing the dpaux device fails, output proper error messages to help diagnose the cause of the failure. Signed-off-by: Thierry Reding

drm/tegra: dpaux: Registers are 32-bit

2015-06-12T14:26:04Z

Use a sized unsigned 32-bit data type (u32) to store register contents. The DPAUX registers are 32 bits wide irrespective of the architecture's data width. Signed-off-by: Thierry Reding

drm/tegra: dpaux: Fix transfers larger than 4 bytes

2015-06-12T14:22:46Z

The DPAUX read/write FIFO registers aren't sequential in the register space, causing transfers larger than 4 bytes to cause accesses to non- existing FIFO registers. Fixes: 6b6b604215c6 ("drm/tegra: Add eDP support") Signed-off-by: Thierry Reding

drm/tegra: Renaming DP training vswing pre emph defines

2014-09-03T09:05:41Z

Rename the defines to have levels instead of values for vswing and pre-emph levels as the values may differ in other scenarios like low vswing of eDP1.4 where the values are different. Done using following cocci patch for each define: @@ @@ # define DP_TRAIN_VOLTAGE_SWING_400 (0 << 0) + # define DP_TRAIN_VOLTAGE_SWING_LEVEL_0 (0 << 0) ...

drm/tegra: add MODULE_DEVICE_TABLEs

2014-08-04T08:07:39Z

When tegra-drm.ko is built as a module, these MODULE_DEVICE_TABLEs allow the module to be auto-loaded since the module will match the devices instantiated from device tree. (Notes for stable: in 3.14+, just git rm any conflicting file, since they are added in later kernels. For 3.13 and below, manual merging will be needed) Cc: Signed-off-by: Stephen Warren Signed-off-by: Thierry Reding
