2014-11-13gpu: host1x: Make mapped field of push buffers void *Thierry Reding
This reduces the amount of casting that needs to be done to get rid of annoying warnings on 64-bit builds. Signed-off-by: Thierry Reding <treding@nvidia.com>
2014-11-13gpu: host1x: Use struct host1x_bo pointers in tracesThierry Reding
Rather than cast to a u32 use the struct host1x_bo pointers directly. This avoid annoying warnings for 64-bit builds. Signed-off-by: Thierry Reding <treding@nvidia.com>
2014-11-13drm/tegra: Depend on COMMON_CLKThierry Reding
The introduction of the COMPILE_TEST dependency in commit 158b50aefa14 (drm/tegra: Increase compile test coverage) removes the dependency on COMMON_CLK (implicitly selected via ARCH_TEGRA, ARCH_MULTI_V7 and ARCH_MULTIPLATFORM).

2014-11-13drm/panel: Add Sharp LQ101R1SX01 supportThierry Reding
This panel requires dual-channel mode. The device accepts command-mode data on 8 lanes and will therefore need a dual-channel DSI controller. The two interfaces that make up this device need to be instantiated in the controllers that gang up to provide the dual-channel DSI host.

2014-11-13drm/dsi: Do not require .owner field to be setThierry Reding
Drivers now no longer need to set the .owner field. It will be automatically set at registration time. Signed-off-by: Thierry Reding <treding@nvidia.com>

2014-11-13drm/dsi: Add to DocBook documentationThierry Reding
Integrate the MIPI DSI helpers into DocBook and clean up various kerneldoc warnings. Also add a brief DOC section and clarify some aspects of the mipi_dsi_host struct's .transfer() operation.

2014-11-13drm/dsi: Implement some standard DCS commandsYoungJun Cho

2014-11-13drm/dsi: Implement generic read and write commandsThierry Reding
Implement generic read and write commands. Selection of the proper data type for packets is done automatically based on the number of parameters or payload length. Reviewed-by: Sean Paul <seanpaul@chromium.org> Signed-off-by: Thierry Reding <treding@nvidia.com>

2014-11-13drm/dsi: Constify mipi_dsi_msgThierry Reding
struct mipi_dsi_msg is a read-only structure, drivers should never need to modify it. Make this explicit by making all references to the struct const. Acked-by: Andrzej Hajda <a.hajda@samsung.com> Reviewed-by: Sean Paul <seanpaul@chromium.org> Signed-off-by: Thierry Reding <treding@nvidia.com>
2014-11-13drm/dsi: Make mipi_dsi_dcs_{read,write}() symmetricalThierry Reding
Currently the mipi_dsi_dcs_write() function requires the DCS command byte to be embedded within the write buffer whereas mipi_dsi_dcs_read() has a separate parameter. Make them more symmetrical by adding an extra command parameter to mipi_dsi_dcs_write(). The S6E8AA0 driver relies on the old asymmetric API and there's concern that moving to the new API may be less efficient. Provide a new function with the old semantics for those cases and make the S6E8AA0 driver use it instead.

2014-11-13drm/dsi: Add DSI transfer helperThierry Reding
A common pattern is starting to emerge for higher level transfer helpers. Create a new helper that encapsulates this pattern and avoids code duplication. Acked-by: Andrzej Hajda <a.hajda@samsung.com> Reviewed-by: Sean Paul <seanpaul@chromium.org> Signed-off-by: Thierry Reding <treding@nvidia.com>
2014-11-13drm/dsi: Add message to packet translatorThierry Reding
This commit introduces a new function, mipi_dsi_create_packet(), which converts from a MIPI DSI message to a MIPI DSI packet. The MIPI DSI packet is as close to the protocol described in the DSI specification as possible and useful in drivers that need to write a DSI packet into a FIFO to send a message off to the peripheral.

2014-11-13drm/gma500: mdfld: Reuse video/mipi_display.hThierry Reding

2014-11-13drm: Make drm_mode_create_tv_properties() signature consistentThierry Reding
The prototype and the function implementation differ in their signature. Make them consistent and use an unsigned integer for the number of modes while at it. Signed-off-by: Thierry Reding <treding@nvidia.com>
2014-11-13drm: Implement drm_get_pci_dev() dummy for !PCIThierry Reding
Implementing a dummy of this function allows drivers that use it to be built on platforms that don't have PCI. This can happen for example if the nouveau driver is built on Tegra without PCI enabled (or on 64-bit ARM where PCI is not yet implemented). Signed-off-by: Thierry Reding <treding@nvidia.com>
2014-11-13drm/prime: Use unsigned type for number of pagesThierry Reding
The number of pages can never be negative, so an unsigned type is enough. This also matches the type of the n_pages argument of the sg_alloc_table_from_pages() function. Signed-off-by: Thierry Reding <treding@nvidia.com>
2014-11-13drm/gem: Fix typo in kerneldocThierry Reding
The function being documented is drm_gem_object_handle_free(), not drm_gem_object_free(). Signed-off-by: Thierry Reding <treding@nvidia.com>
2014-11-13drm: Use const data when creating blob propertiesThierry Reding
Creating a blob property will always copy the input data so the data that is passed in can be const. Signed-off-by: Thierry Reding <treding@nvidia.com>
2014-11-13drm: Use size_t for blob property sizesThierry Reding
size_t is the standard type when dealing with sizes of all kinds. Use it consistently when instantiating DRM blob properties. Signed-off-by: Thierry Reding <treding@nvidia.com>
