Yakir Yang says: For Designerware HDMI, the following write sequence is recommended: 1. aud_n3 (set bit ncts_atomic_write if desired) 2. aud_cts3 (set CTS_manual and CTS value if desired/enabled) 3. aud_cts2 (required in CTS_manual) 4. aud_cts1 (required in CTS_manual) 5. aud_n3 (bit ncts_atomic_write with same value as in step 1.) 6. aud_n2 7. aud_n1 However, avoid the ncts_atomic_write_bit and CTS_manual settings in this patch, both of which are marked reserved in the iMX6 documentation. All iMX6 code in the wild seems to want CTS_manual cleared. Having requested clarification from FSL, it appears that neither of these bits are implemented in their version of the IP.

This needs to be protected against concurrency as there is no synchronisation between these two operations. Introduce a mutex (called audio_mutex) to protect against two threads trying to update the video clock rate and pixel clock simultaneously.

This is used by the core shadowing code to prevent re-fetching chunks of the image that have already been shadowed. The ACPI fetching code may possibly need to extend this further due to requiring fetches to happen in 4KiB chunks. Under certain circumstances (that happen if the total image size is a multiple of 4KiB), the memory allocated to store the shadow will already be big enough, causing the ACPI code's nvbios_extend() call to return 0, which is misinterpreted as a failure. The fix is simple, accept >= 0 as a successful condition here. The core will have already made sure that we're not re-fetching data we already have.

ARM has a property that may prevent this from happening though: memory can be mapped multiple times only if the different mappings share the same caching properties. However all the lowmem memory is already identity-mapped into the kernel with cache enabled, so when user-space requests an uncached mapping, we actually get an "undefined caching policy" one and this has strange side-effects described on Freedesktop bug 86690. To prevent this from happening, allow user-space to explicitly specify which objects should be coherent, and create such objects with the TTM_PL_FLAG_UNCACHED flag. This will make TTM allocate memory using the DMA API, which will fix the identify mapping and allow us to safely map the objects to user-space uncached.
