drm/bridge: tc358767: fix max_tu_symbol value

2019-10-10T09:15:45Z

max_tu_symbol was programmed to TU_SIZE_RECOMMENDED - 1, which is not what the spec says. The spec says: roundup ((input active video bandwidth in bytes/output active video bandwidth in bytes) * tu_size) It is not quite clear what the above means, but calculating max_tu_symbol = (input Bps / output Bps) * tu_size seems to work and fixes the issues seen. This fixes artifacts in some videomodes (e.g. 1024x768@60 on 2-lanes & 1.62Gbps was pretty bad for me).

Revert "drm/bridge: adv7511: Attach to DSI host at probe time"

2019-09-13T07:25:00Z

This reverts commit 83f35bc3a852f1c3892c7474998c5cec707c7ba3. There are at least two DSI controller drivers which relies on the old behaviour of adv7511 driver. To avoid platform breakage this patch should be reverted. This is a temporary solution, as it blocks adv7511 usage with other platforms. Assumption that DSI device driver (bridge/panel) should first expose drm_bridge/drm_panel object, then look for DSI bus is just incorrect - it can work with devices controlled via i2c but it cannot work with devices controlled via DSI - they will not be able to probe. To solve the issue following steps should be performed: - rework reverted patch allowing co-operation with broken DSI controller drivers - with simple/ugly workaround, - fix controller drivers and then remove workaround.

Use the new cec_notifier_conn_(un)register() functions to (un)register the notifier for the HDMI connector, and fill in the cec_connector_info.

Changes since v4: - typo fix Changes since v2: - removed unnecessary NULL check before a call to cec_notifier_conn_unregister, - use cec_notifier_phys_addr_invalidate to invalidate physical address. Changes since v1: Add memory barrier to make sure that the notifier becomes visible to the irq thread once it is fully constructed.
