Skipping just one branch of the tree is not the most effective approach. Instead use a macro to define the traversal functions and sort out both branch sides. This improves the performance of the unit tests by a factor of more than 4. Signed-off-by:

Ricardo Cañuelo authored
The tfp410 has a data de-skew feature that allows the user to compensate the skew between IDCK and the pixel data and control signals. In the driver, the setup and hold times are calculated from the de-skew value. This retrieves the deskew value from the DT using the proper datatype and range check as described by the binding (u32 from 0 to 7). This fix results from a change in the ti,tfp410 DT binding.

Ricardo Cañuelo authored
This changes how the 'ti,deskew' property is defined. It's now an unsigned value from 0 to 7 instead of a signed value from -4 to 3. Until the dtc carries the integer sign through to the yaml output it's easier to define signed types as unsigned. Signed-off-by:

The DRM panel bridge core requires connector type to be set up properly, otherwise it rejects the panel. The missing connector type problem popped up while I was trying to wrap CLAA070WP03XG panel into a DRM bridge in order to test whether panel's rotation property work properly using panel-simple driver on NVIDIA Tegra30 Nexus 7 tablet device, which uses CLAA070WP03XG display panel. The NVIDIA Tegra DRM driver recently gained DRM bridges support for the RGB output and now driver wraps directly-connected panels into DRM bridge. Hence all panels should have connector type set properly now, otherwise the panel's wrapping fails. This patch adds missing connector types for the LVDS panels that are found on NVIDIA Tegra devices: 1. AUO B101AW03 2. Chunghwa CLAA070WP03XG 3. Chunghwa CLAA101WA01A 4. Chunghwa CLAA101WB01 5.

DRM_FORMAT_NV15 is a 2 plane format suitable for linear and 16x16 block-linear memory layouts (DRM_FORMAT_MOD_SAMSUNG_16_16_TILE). The format is similar to P010 with 4:2:0 sub-sampling but has no padding between components. Instead, luminance and chrominance samples are grouped into 4s so that each group is packed into an integer number of bytes: YYYY = UVUV = 4 * 10 bits = 40 bits = 5 bytes The '15' suffix refers to the optimum effective bits per pixel which is achieved when the total number of luminance samples is a multiple of 8. Q410 and Q401 are both 3 plane non-subsampled formats with 16 bits per component, but only 10 bits are used and 6 are padded. 'Q' is chosen as the first letter to denote 3 plane YUV444, (and is the next letter along from P which is usually 2 plane).

Steven Price authored
The calls to panfrost_devfreq_record_busy() and panfrost_devfreq_record_idle() must be balanced to ensure that the devfreq utilisation is correctly reported. But there are two cases where this doesn't work correctly. In panfrost_job_hw_submit() if pm_runtime_get_sync() fails or the WARN_ON() fires then no call to panfrost_devfreq_record_busy() is made, but when the job times out the corresponding _record_idle() call is still made in panfrost_job_timedout(). Move the call up to ensure that it always happens. Secondly panfrost_job_timedout() only makes a single call to panfrost_devfreq_record_idle() even if it is cleaning up multiple jobs. Move the call inside the loop to ensure that the number of _record_idle() calls matches the number of _record_busy() calls.

The kernel test robot noted that if "OF" is defined (which is needed to select DRM_TI_SN65DSI86 at all) but not OF_GPIO that we'd get compile failures because some of the members that we access in "struct gpio_chip" are only defined "#if defined(CONFIG_OF_GPIO)". All the GPIO bits in the driver are all nicely separated out. We'll guard them with the same "#if defined" that the header has and add a little stub function if OF_GPIO is not defined.

Compared to its predecessors, the PX30 VOP has a different register layout for enabling per-pixel alpha. Instead of src_alpha_ctl and dst_alpha_ctl, there is a single alpha control register. This register takes some fields from src_alpha_ctl, but with a different layout. Add support for the required fields to the PX30 VOP window descriptions, which makes per-pixel-alpha formats behave correctly. Signed-off-by:
