[ Upstream commit 85fb3526 ] The current code allows the TCON clock divider to have a range between 4 and 127 when feeding the DSI controller. The only display supported so far had a display clock rate that ended up using a divider of 4, but testing with other displays show that only 4 seems to be functional. This also aligns with what Allwinner is doing in their BSP, so let's just hardcode that we want a divider of 4 when using the DSI output. Reviewed-by:

[ Upstream commit da676c6a ] The current calculation for the video start delay in the current DSI driver is that it is the total vertical size, minus the front porch and sync length, plus 1. This equals to the active vertical size plus the back porch plus 1. That 1 is coming in the Allwinner BSP from an variable that is set to 1. However, if we look at the Allwinner BSP more closely, and especially in the "legacy" code for the display (in drivers/video/sunxi/legacy/), we can see that this variable is actually computed from the porches and the sync minus 10, clamped between 8 and 100. This fixes the start delay symptom we've seen on some panels (vblank timeouts with vertical white stripes at the bottom of the panel). Reviewed-by:

[ Upstream commit 60b80199 ] After an event is sent, we try to copy it into the user buffer of the first waiter in drm_read() and if the user buffer doesn't have enough room we put it back onto the list. However, we didn't wake up any subsequent waiter, so that event may sit on the list until either a new vblank event is sent or a new waiter appears. Rare, but in the worst case may lead to a stuck process. Testcase: igt/drm_read/short-buffer-wakeup Signed-off-by:

[ Upstream commit 4bc46da4 ] [Why] Seamless boot tries to reuse planes that were enabled for the first commit applied. In the case where Raven is booting with two monitors connected and the first commit contains two streams the screen corruption would occur because the second stream was trying to re-use a tg and plane that weren't previously enabled. The state on the first commit looks something like the following: TG0: enabled=1 TG1: enabled=0 TG2: enabled=0 TG3: enabled=0 New state: pipe=0, stream=0, plane=0, new_tg=0 New state: pipe=1, stream=1, plane=1, new_tg=1 New state: pipe=2, stream=NULL, plane=NULL, new_tg=NULL New state: pipe=3, stream=NULL, plane=NULL, new_tg=NULL Only one plane/tg is setup before we enter accelerated mode so we really want to disabling everything but that first plane. [How] Check if the stream is not NULL and if the tg is enabled before deciding whether to skip the plane disable. Also ensure we're also disabling on the current state's pipe_ctx so we don't overwrite the fields in the new pending state. Signed-off-by:

[ Upstream commit 7d7b25d0 ] The SND_SOC_DAVINCI_MCASP driver can use either edma or sdma as a back-end, and it takes the presence of the respective dma engine drivers in the configuration as an indication to which ones should be built. However, this is flawed in multiple ways: - With CONFIG_TI_EDMA=m and CONFIG_SND_SOC_DAVINCI_MCASP=y, is enabled as =m, and we get a link error: sound/soc/ti/davinci-mcasp.o: In function `davinci_mcasp_probe': davinci-mcasp.c:(.text+0x930): undefined reference to `edma_pcm_platform_register' - When CONFIG_SND_SOC_DAVINCI_MCASP=m has already been selected by another driver, the same link error appears even if CONFIG_TI_EDMA is disabled There are possibly other issues here, but it seems that the only reasonable solution is to always build both SND_SOC_TI_EDMA_PCM and SND_SOC_TI_SDMA_PCM as a dependency here. Both are fairly small and do not have any other compile-time dependencies, so the cost is very small, and makes the configuration stage much more consistent.

[ Upstream commit 5442dcaa ] This fixes a bug for messages containing both zero length and unidirectional xfers. The function spi_map_msg will allocate dummy tx and/or rx buffers for use with unidirectional transfers when the hardware can only do a bidirectional transfer. That dummy buffer will be used in place of a NULL buffer even when the xfer length is 0. Then in the function __spi_map_msg, if he hardware can dma, the zero length xfer will have spi_map_buf called on the dummy buffer. Eventually, __sg_alloc_table is called and returns -EINVAL because nents == 0. This fix prevents the error by not using the dummy buffer when the xfer length is zero. Signed-off-by:

[ Upstream commit c842749e ] Commit 71abd290 ("spi: imx: Add support for SPI Slave mode") added an RX FIFO flush before start of a transfer. In slave mode, the master may have sent more data than expected and this data will still be in the RX FIFO at the start of the next transfer, and so needs to be flushed. However, the code to do the flush was accidentally saving this data into the previous transfer's RX buffer, clobbering the contents of whatever followed that buffer. Change it to empty the FIFO and throw away the data. Every one of the RX functions for the different eCSPI versions and modes reads the RX FIFO data using the same readl() call, so just use that, rather than using the spi_imx->rx function pointer and making sure all the different rx functions have a working "throw away" mode. There is another issue, which affects master mode when switching from DMA to PIO. There can be extra data in the RX FIFO which triggers this flush code, causing memory corruption in the same manner. I don't know why this data is unexpectedly in the FIFO. It's likely there is a different bug or erratum responsible for that. But regardless of that, I think this is proper fix the for bug at hand here.

[ Upstream commit fe4ed1b4 ] Currently dsi_display_init_dsi() calls dss_pll_enable() but it is not paired with dss_pll_disable() in dsi_display_uninit_dsi(). This leaves the DSS clocks enabled when the display is blanked wasting about extra 5mW of power while idle. The clock that is left on by not calling dss_pll_disable() is DSS_CLKCTRL bit 10 OPTFCLKEN_SYS_CLK that is the source clock for DSI PLL. We can fix this issue by by making the current dsi_pll_uninit() into dsi_pll_disable(). This way we can just call dss_pll_disable() from dsi_display_uninit_dsi() and the code becomes a bit easier to follow. However, we need to also consider that DSI PLL can be muxed for DVI too as pointed out by Tomi Valkeinen <tomi.valkeinen@ti.com>. In the DVI case, we want to unconditionally disable the clocks. To get around this issue, we separate out the DSI lane handling from dsi_pll_enable() and dsi_pll_disable() as suggested by Tomi in an earlier experimental patch. So we must only toggle the DSI regulator based on the vdds_dsi_enabled flag from dsi_display_init_dsi() and dsi_display_uninit_dsi(). We need to make these two changes together to avoid breaking things for DVI when fixing the DSI clock handling. And this all causes a slight renumbering of the error path for dsi_display_init_dsi().

[ Upstream commit e482ae9b ] Writeback jobs are allocated when the WRITEBACK_FB_ID is set, and deleted when the jobs complete. This results in both a memory leak of the job and a leak of the framebuffer if the atomic commit returns before the job is queued for processing, for instance if the atomic check fails or if the commit runs in test-only mode. Fix this by implementing the drm_writeback_cleanup_job() function and calling it from __drm_atomic_helper_connector_destroy_state(). As writeback jobs are removed from the state when they're queued for processing, any job left in the state when the state gets destroyed needs to be cleaned up. The existing declaration of the drm_writeback_cleanup_job() function without an implementation hints that this problem was considered, but never addressed. Signed-off-by:

This created a lock heirarchy dependent upon irq being disabled, and there are paths that take the io_buf_list_put_lock without disabling irq. Looking at the lpfc_io_free routine, which is where the new heirarchy was introduced, there is no reason to be taking out the hbalock and raising irq, as the functionality is replaced by the io_buf_list_xxx locks. Resolve by removing the hbalock/irq calls in lpfc_io_free. Fixes: 5e5b511d ("scsi: lpfc: Partition XRI buffer list across Hardware Queues") Reported-by:

[ Upstream commit e8869f5b ] The adapter initialization sequence enables interrupts, initializes the adapter link_state to LINK_DOWN, then issues commands to initialize the adapter. The interrupt handler on the adapter validates the link_state (has to be at least LINK_DOWN) and if invalid, will discard the interrupting event. In most cases, there is not a command completion, thus an interrupt until the initialization commands have been sent which is post the setting of state to LINK_DOWN. However, in cases of firmware reset, the reset will modify the link_state to an invalid value (indicating a reset of the adapter) and there occasionally are cases where the adapter will generate an asynchronous event which shares the eq/cq used for mailbox commands. In the failure case, an interrupt is generated immediately after enabling them due to the async event. As link_state is invalid, the eq is list and the CQ not serviced. At this point link_state is initialized and the mailbox command sent. As the CQ has not been serviced, it is not armed, so no interrupt event is generated when the mailbox command completes. Modify the initialization sequence so that interrupts are enabled after link_state is properly initialized, which avoids the race condition with the async event. Signed-off-by:
