2022-03-31random: mix build-time latent entropy into pool at initJason A. Donenfeld1-0/+5
Prior, the "input_pool_data" array needed no real initialization, and so it was easy to mark it with __latent_entropy to populate it during compile-time. In switching to using a hash function, this required us to specifically initialize it to some specific state, which means we dropped the __latent_entropy attribute. An unfortunate side effect was this meant the pool was no longer seeded using compile-time random data. In order to bring this back, we declare an array in rand_initialize() with __latent_entropy and call mix_pool_bytes() on that at init, which accomplishes the same thing as before. We make this __initconst, so that it doesn't take up space at runtime after init.

2022-03-31Revert "drm/bridge: dw-mipi-dsi: Find the possible DSI devices"Jagan Teki1-43/+15
This reverts commit c206c7faeb3263a7cc7b4de443a3877cd7a5e74b. In order to avoid any probe ordering issues, the I2C based downstream bridge drivers now register and attach the DSI devices at the probe instead of doing it on drm_bridge_function.attach(). Examples of those commits are: commit <6ef7ee48765f> ("drm/bridge: sn65dsi83: Register and attach our DSI device at probe") commit <d89078c37b10> ("drm/bridge: lt8912b: Register and attach our DSI device at probe") commit <864c49a31d6b> ("drm/bridge: adv7511: Register and attach our DSI device at probe") dw-mipi-dsi has panel or bridge finding code based on previous downstream bridges, so revert the same and make the panel or bridge funding in host attach as before.

2022-03-31drm: bridge: icn6211: Add generic DSI-to-DPI PLL configurationMarek Vasut1-3/+86
The chip contains fractional PLL, however the driver currently hard-codes one specific PLL setting. Implement generic PLL parameter calculation code, so any DPI panel with arbitrary pixel clock can be attached to this bridge. The datasheet for this bridge is not available, the PLL behavior has been inferred from [1] and [2] and by analyzing the DPI pixel clock with scope. The PLL limits might be wrong, but at least the calculated values match all the example code available. This is better than one hard-coded pixel clock value anyway.

2022-03-31drm/bridge: tc358767: Add DSI-to-DPI mode supportMarek Vasut2-11/+348
The TC358767/TC358867/TC9595 are all capable of operating in multiple modes, DPI-to-(e)DP, DSI-to-(e)DP, DSI-to-DPI. Add support for the DSI-to-DPI mode. This requires skipping most of the (e)DP initialization code, which is currently a large part of this driver, hence it is better to have far simpler separate tc_dpi_bridge_funcs and their implementation. The configuration of DPI output is also much simpler. The configuration of the DSI input is rather similar to the other TC bridge chips. The Pixel PLL in DPI output mode does not have the 65..150 MHz limitation imposed on the (e)DP output mode, so this limitation is skipped to permit operating panels with far slower pixel clock, even below 9 MHz. This mode of operation of the PLL is valid and tested. The detection of bridge mode is now added into tc_probe_bridge_mode(), where in case a DPI panel is found on port@1 endpoint@1, the mode is assumed to be DSI-to-DPI. If (e)DP is detected on port@2, the mode is assumed to be DPI-to-(e)DP. The DSI-to-(e)DP mode is not supported due to lack of proper hardware, but this would be some sort of mix between the two aforementioned modes.
