+Subject: ARM: dts: am43x-epos-evm: Reduce i2c0 bus speed for tps65218
+
+From: Dave Gerlach <d-gerlach@ti.com>
+
+[ Upstream commit 20a6b3fd8e2e2c063b25fbf2ee74d86b898e5087 ]
+
+Based on the latest timing specifications for the TPS65218 from the data
+sheet, http://www.ti.com/lit/ds/symlink/tps65218.pdf, document SLDS206
+from November 2014, we must change the i2c bus speed to better fit within
+the minimum high SCL time required for proper i2c transfer.
+
+When running at 400khz, measurements show that SCL spends
+0.8125 uS/1.666 uS high/low which violates the requirement for minimum
+high period of SCL provided in datasheet Table 7.6 which is 1 uS.
+Switching to 100khz gives us 5 uS/5 uS high/low which both fall above
+the minimum given values for 100 khz, 4.0 uS/4.7 uS high/low.
+
+Without this patch occasionally a voltage set operation from the kernel
+will appear to have worked but the actual voltage reflected on the PMIC
+will not have updated, causing problems especially with cpufreq that may
+update to a higher OPP without actually raising the voltage on DCDC2,
+leading to a hang.

+Subject: dmaengine: of-dma: router_xlate to return -EPROBE_DEFER if controller
+ is not yet available
+
+From: Peter Ujfalusi <peter.ujfalusi@gmail.com>
+
+[ Upstream commit eda97cb095f2958bbad55684a6ca3e7d7af0176a ]
+
+If the router_xlate can not find the controller in the available DMA
+devices then it should return with -EPORBE_DEFER in a same way as the
+of_dma_request_slave_channel() does.
+
+The issue can be reproduced if the event router is registered before the
+DMA controller itself and a driver would request for a channel before the
+controller is registered.
+In of_dma_request_slave_channel():
+1. of_dma_find_controller() would find the dma_router
+2. ofdma->of_dma_xlate() would fail and returned NULL
+3. -ENODEV is returned as error code
+
+with this patch we would return in this case the correct -EPROBE_DEFER and
+the client can try to request the channel later.

+Subject: scsi: core: Avoid printing an error if target_alloc() returns -ENXIO
+
+From: Sreekanth Reddy <sreekanth.reddy@broadcom.com>
+
+[ Upstream commit 70edd2e6f652f67d854981fd67f9ad0f1deaea92 ]
+
+Avoid printing a 'target allocation failed' error if the driver
+target_alloc() callback function returns -ENXIO. This return value
+indicates that the corresponding H:C:T:L entry is empty.
+
+Removing this error reduces the scan time if the user issues SCAN_WILD_CARD
+scan operation through sysfs parameter on a host with a lot of empty
+H:C:T:L entries.
+
+Avoiding the printk on -ENXIO matches the behavior of the other callback
+functions during scanning.

+
+[ Upstream commit 77541f78eadfe9fdb018a7b8b69f0f2af2cf4b82 ]
+
+The list_for_each_entry() iterator, "adapter" in this code, can never be
+NULL. If we exit the loop without finding the correct adapter then
+"adapter" points invalid memory that is an offset from the list head. This
+will eventually lead to memory corruption and presumably a kernel crash.
