Use the device version queried at runtime instead of the device type provided through platform data to handle the overflow workaround. This will make support of other SoCs integrating the same HDMI TX controller version easier. Among the supported platforms only i.MX6DL and i.MX6Q have been identified as needing the workaround. Disabling it on Rockchip RK3288 (which integrates a v2.00a controller) didn't produce any error or artifact. Signed-off-by:

Bit 0 in CONFIG1_ID tells whether the IP core uses an AHB slave interface for control. The correct way to identify AHB audio DMA support is through bit 1 in CONFIG3_ID. Signed-off-by:

The DWC HDMI TX can be recognized by the two product identification registers. If the registers don't read as expect the IP will be very different than what the driver has been designed for, or will be misconfigured in a way that makes it non-operational (invalid memory address, incorrect clocks, ...). We should reject this situation with an error. While this isn't critical for proper operation with supported IPs at the moment, the driver will soon gain automatic device-specific handling based on runtime device identification. This change makes it easier to implement that without having to default to a random guess in case the device can't be identified. While at it print a readable version number in the device identification message instead of raw register values. Signed-off-by:

The bit is documented in a Rockchip BSP as #define m_SVSRET_SIG (1 << 5) /* depend on PHY_MHL_COMB0=1 */ This is confirmed by a Renesas platform, which uses a 2.0 DWC HDMI TX as the RK3288. Rename the bit accordingly. Signed-off-by:

The current code hard codes the call of hdmi_phy_configure() to be 8bpp and provides extraneous error checking to verify that this hardcoded value is correct. Simplify the implementation by removing the argument. Signed-off-by:

As an option for drivers not based on the component framework, register the bridge with the DRM core with the DRM bridge API. Existing drivers based on dw_hdmi_bind() and dw_hdmi_unbind() are not affected as those functions are preserved with their current behaviour. Signed-off-by:
-
Laurent Pinchart authored
The DRM device is not guaranteed by the bridge API to be available before the attach callback. The driver performs properly at the moment as it doesn't use the drm_bridge_add() registration method. As this will be changed later, move connector creation to attach time to ensure compatibility with the API. Signed-off-by:

Laurent Pinchart authored
There's no need to duplicate identical code in multiple drivers (two at the moment, one more to come soon). Move it to the dw-hdmi core where it can be shared. If resource allocation ever becomes device-specific later we'll always have the option of splitting it out again. While it at pass the platform device to the bind function to avoid having to cast struct device to struct platform_device. Signed-off-by:

The 'prep' parameter passed to hdmi_phy_configure() is useless. It is hardcoded as 0, and if set, simply prevents the configure function from executing. Remove it. Signed-off-by:

The master argument isn't used. The data argument, a void pointer, is used by the bind function only where it's cast to a drm_device pointer, which can easily be obtained from the encoder argument instead. Remove them. Signed-off-by:

The latter is just an int wrapper around the former void function that unconditionally returns 0. As the return value is never checked, merge the two functions into one. Signed-off-by:

Registering the connector explicitly right after creation is not necessary for modesetting drivers, because drm_dev_register already takes care of this on the core side, by calling drm_modeset_register_all. In addition, performing the initialization too early will get in the way of the load() hook removal, because the connector interface cannot be published prior to registering the minors.

This is the deprecated function for when you embedded the framebuffer somewhere else (which breaks refcounting). But Tegra is using drm_framebuffer_remove and a free-standing FB, so this is redundant. One caveat here is that the failure path in the init code still manually cleaned up the fb. I presume that was an oversight and changed it over to drm_framebuffer_remove too. Cc: Thierry Reding <thierry.reding@gmail.com> Reviewed-by:

The dma_fence.error field (formerly known as dma_fence.status) is an optional field that may be set by drivers before calling dma_fence_signal(). The field can be used to indicate that the fence was completed in err rather than with success, and is visible to other consumers of the fence and to userspace via sync_file. This patch renames the field from status to error so that its meaning is hopefully more clear (and distinct from dma_fence_get_status() which is a composite between the error state and signal state) and adds a helper that validates the preconditions of when it is suitable to adjust the error field.

The fence->status is an optional field that is only valid once the fence has been signaled. (Driver may fill the fence->status with an error code prior to calling dma_fence_signal().) Given the restriction upon its validity, wrap querying of the fence->status into a helper dma_fence_get_status(). Signed-off-by:

Chris Wilson authored
As the fence->status is an optional field that may be set before dma_fence_signal() is called to convey that the fence completed with an error, we have to ensure that it is always set to zero on initialisation so that the typical use (i.e. unset) always flags a successful completion. Signed-off-by:
