From: Srinivas Kandagatla <srinivas.kandagatla@xxxxxxxxxx> Hi Andy, I did hit few issues while trying out SLIMBus BAM on DB820c, this BAM instance is remotely controlled and powered up after ADSP is booted using QMI commands. Firstly some of the master registers are written even when the BAM is remotely controlled, and secondly reading registers when bam is not ready yet. These 4 patches address these issues, there are few more issues like doing PM in simillar usecase, these will be addressed soon. Thanks, Srini Changes since v2: return clk error in default case, suggested by Bjorn Srinivas Kandagatla (5): dmaengine: qcom: bam_dma: make bam clk optional dt-bindings: dmaengine: bam_dma: add remote controlled bindings dmaengine: qcom: bam_dma: get num-channels and num-ees from dt dmaengine: qcom: bam_dma: do not write to global regs in remote mode dmaengine: qcom: bam_dma: disable runtime pm on remote controlled .../devicetree/bindings/dma/qcom_bam_dma.txt | 4 ++ drivers/dma/qcom/bam_dma.c | 59 +++++++++++++++++----- 2 files changed, 49 insertions(+), 14 deletions(-) -- 2.15.1 -- To unsubscribe from this list: send the line "unsubscribe dmaengine" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
