drm/vc4: hdmi: Update the CEC clock divider on HSM rate change

2021-03-04T10:37:49+00:00

[ Upstream commit 47fa9a80270e20a0c4ddaffca1f144d22cc59620 ] As part of the enable sequence we might change the HSM clock rate if the pixel rate is different than the one we were already dealing with. On the BCM2835 however, the CEC clock derives from the HSM clock so any rate change will need to be reflected in the CEC clock divider to output 40kHz.

drm/vc4: hdmi: Compute the CEC clock divider from the clock rate

2021-03-04T10:37:48+00:00

[ Upstream commit 163a3ef681e5e9d5df558e855d86ccd4708d6200 ] The CEC clock divider needs to output a frequency of 40kHz from the HSM rate on the BCM2835. The driver used to have a fixed frequency for it, but that changed for the BCM2711 and we now need to compute it dynamically to maintain the proper rate.

drm/vc4: hdmi: Restore cec physical address on reconnect

2021-03-04T10:37:48+00:00

[ Upstream commit 4d8602b8ec16f5721a4d1339c610a81f95df1856 ] Currently we call cec_phys_addr_invalidate on a hotplug deassert. That may be due to a TV power cycling, or an AVR being switched on (and switching edid). This makes CEC unusable since our controller wouldn't have a physical address anymore.

drm/vc4: hdmi: Fix register offset with longer CEC messages

[ Upstream commit 4a59ed546c0511f01a4bf6b886fe34b6cce2513f ] The code prior to 311e305fdb4e ("drm/vc4: hdmi: Implement a register layout abstraction") was relying on the fact that the register offset was incremented by 4 for each readl call. That worked since the register width is 4 bytes. However, since that commit the HDMI_READ macro is now taking an enum, and the offset doesn't increment by 4 but 1 now. Divide the index by 4 to fix this.

drm/vc4: hvs: Fix buffer overflow with the dlist handling

[ Upstream commit facd93f4285c405f9a91b05166147cb39e860666 ] Commit 0a038c1c29a7 ("drm/vc4: Move LBM creation out of vc4_plane_mode_set()") changed the LBM allocation logic from first allocating the LBM memory for the plane to running mode_set, adding a gap in the LBM, and then running the dlist allocation filling that gap. The gap was introduced by incrementing the dlist array index, but was never checking whether or not we were over the array length, leading eventually to memory corruptions if we ever crossed this limit. vc4_dlist_write had that logic though, and was reallocating a larger dlist array when reaching the end of the buffer. Let's share the logic between both functions.
