Message-ID<q571T-5Xr-15@gated-at.bofh.it>
To help the user, print the PDSP file name as part of
knav_queue_load_pdsp(). This will be useful for users to know what
version of the firmware is loaded to PDSP. Also update the
document for the location of the QMSS accumulator PDSP firmware.

+Accumulator QMSS Channel using PDSP firmware
+============================================
+The QMSS PDSP firmware support accumulator channel that can monitor a single
+queue or multiple contiguous queues. drivers/soc/ti/knav_qmss_acc.c is the
+driver that interface with the accumulator PDSP. This configures
+accumulator channels defined in DTS (example above) to monitor 1 or 32 queues
+per channel. More description on the firmware is available in CPPI/QMSS Low
+Level Driver document (docs/CPPI_QMSS_LLD_SDS.pdf) at
+	git://git.ti.com/keystone-rtos/qmss-lld.git
+
+k2_qmss_pdsp_acc48_k2_le_1_0_0_9.bin firmware supports upto 48 accumulator
+channels. This firmware is available under firmware folder of the above repo
+under the name acc48_le.bin. To use copy the firmware image to lib/firmware
+folder of the initramfs or ubifs file system as
+k2_qmss_pdsp_acc48_k2_le_1_0_0_9.bin and boot up the kernel. User would see
+"firmware file ks2_qmss_pdsp_acc48_k2_le_1_0_0_9.bin downloaded for PDSP" in
+the boot up log if loading of firmware to PDSP is successful.

#1219337 — [PATCH v1 2/2] ARM: dts: keystone: enable accumulator channels

FromMurali Karicheri <m-karicheri2@ti.com>
Date2015-09-04 23:50 +0200
Subject[PATCH v1 2/2] ARM: dts: keystone: enable accumulator channels
Message-ID<q571U-5Xr-17@gated-at.bofh.it>
In reply to#1219336
Add low priority accumulator channel that can monitor multiple QMSS
queues. User for example could use the accumular queue for Netcp
Rx completion. While at it, also add an extra line end of each top
level node in DTS to make it more readable.

Looks fine. Will pick both the patches.
