mmc: mmci: Fix device_node reference leak in of_get_dml_pipe_index()

2026-03-19T15:15:09Z

commit af12e64ae0661546e8b4f5d30d55c5f53a11efe7 upstream. When calling of_parse_phandle_with_args(), the caller is responsible to call of_node_put() to release the reference of device node. In of_get_dml_pipe_index(), it does not release the reference. Fixes: 9cb15142d0e3 ("mmc: mmci: Add qcom dml support to the driver.")

mmc: mmci: qcom: define get_dctrl_cfg

2019-04-15T09:55:54Z

This patch defines get_dctrl_cfg callback for qcom variant. qcom variant has a specific block size definition. Signed-off-by: Ludovic Barre Signed-off-by: Ulf Hansson

mmc: mmci: Re-work code starting DMA for the qcom variant

2019-04-15T09:55:54Z

Having mmci_dmae_start() to invoke the shared function, dml_start_xfer(), explicitly for the qcom variant isn't very nice. Let's clean up this code by moving the qcom specific parts into the qcom ->dma_start() callback and then drop dml_start_xfer() altogether. Signed-off-by: Ulf Hansson Acked-by: Linus Walleij

mmc: mmci: Drop unnecessary clear of variant->qcom_dml flag

2019-04-15T09:55:54Z

There's no point clearing the variant flag in case the qcom variant fails to setup DMA. This is because if mmci_dma_setup() fails, then the use_dma flag remains set to false, which leads to mmci using PIO mode and not DMA. Signed-off-by: Ulf Hansson Acked-by: Linus Walleij

mmc: mmci: add dma_error callback

mmc: mmci: add dma_start callback

2018-10-09T07:13:03Z

This patch adds dma_start callback to mmci_host_ops. Create a generic mmci_dma_start function which regroup common action between variant. Signed-off-by: Ludovic Barre Signed-off-by: Ulf Hansson

mmc: mmci: add get_next_data callback

2018-10-09T07:13:03Z

This patch adds get_next_data callback to mmci_host_ops. Generic mmci_get_next_data factorizes next_cookie check and the host ops call. Signed-off-by: Ludovic Barre Signed-off-by: Ulf Hansson

mmc: mmci: add prepare/unprepare_data callbacks

2018-10-09T07:13:03Z

This patch adds prepare/unprepare callbacks to mmci_host_ops. Like this mmci_pre/post_request can be generic, mmci_prepare_data and mmci_unprepare_data provide common next_cookie management. Signed-off-by: Ludovic Barre Signed-off-by: Ulf Hansson
