+Subject: spi: qup: Add DMA capabilities
+From: Andy Gross <agross@codeaurora.org>
+X-Patchwork-Id: 4432401

+
+This patch adds DMA capabilities to the spi-qup driver. If DMA channels are
+present, the QUP will use DMA instead of block mode for transfers to/from SPI
+peripherals for transactions larger than the length of a block.

+
+This patch fixes a number of errors with the QUP block transfer mode. Errors
+manifested themselves as input underruns, output overruns, and timed out
+transactions.
+
+The block mode does not require the priming that occurs in FIFO mode. At the
+moment that the QUP is placed into the RUN state, the QUP will immediately raise
+an interrupt if the request is a write. Therefore, there is no need to prime
+the pump.
+
+In addition, the block transfers require that whole blocks of data are
+read/written at a time. The last block of data that completes a transaction may
+contain less than a full blocks worth of data.
+
+Each block of data results in an input/output service interrupt accompanied with
+a input/output block flag set. Additional block reads/writes require clearing
+of the service flag. It is ok to check for additional blocks of data in the
+ISR, but you have to ack every block you transfer. Imbalanced acks result in
+early return from complete transactions with pending interrupts that still have
+to be ack'd. The next transaction can be affected by these interrupts.
+Transactions are deemed complete when the MAX_INPUT or MAX_OUTPUT flag are set.
+
+Changes from v2:
+- Added in additional completion check so that transaction done is not
+ prematurely signaled.
+- Fixed various review comments.
+
+Changes from v1:
+- Split out read/write block function.
+- Removed extraneous checks for transfer length
+

+Subject: [PATCH] spi: qup: Ensure done detection
+
+This patch fixes an issue where a SPI transaction has completed, but the done
+condition is missed. This occurs because at the time of interrupt the
+MAX_INPUT_DONE_FLAG is not asserted. However, in the process of reading blocks
+of data from the FIFO, the last portion of data comes in.
+
+The opflags read at the beginning of the irq handler no longer matches the
+current opflag state. To get around this condition, the block read function
+should update the opflags so that done detection is correct after the return.

+Subject: [PATCH 1/3] watchdog: qcom: use timer devicetree binding
+
+MSM watchdog configuration happens in the same register block as the
+timer, so we'll use the same binding as the existing timer.
+
+The qcom-wdt will now be probed when devicetree has an entry compatible
+with "qcom,kpss-timer" or "qcom-scss-timer".
