For the compatibility of NXP internal legacy kernel before 4.19 which is based on uart ram script and upstreaming kernel based on uart rom script, add both uart ram/rom script in latest sdma firmware. By default uart rom script used. Besides, add two multi-fifo scripts for SAI/PDM on i.mx8m/8mm and add back qspi script miss for v4(i.mx7d/8m/8mm family, but v3 is for i.mx6).
rom script: uart_2_mcu_addr uartsh_2_mcu_addr /* through spba bus */ am script: uart_2_mcu_ram_addr uartsh_2_mcu_ram_addr /* through spba bus */ Please get latest sdma firmware from the below and put them into the path (/lib/firmware/imx/sdma/): https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git /tree/imx/sdma Signed-off-by: Robin Gong <yibin.g...@nxp.com> Acked-by: Vinod Koul <vk...@kernel.org> --- drivers/dma/imx-sdma.c | 4 ++-- include/linux/platform_data/dma-imx-sdma.h | 8 ++++++-- 2 files changed, 8 insertions(+), 4 deletions(-) diff --git a/drivers/dma/imx-sdma.c b/drivers/dma/imx-sdma.c index 320104f..2ca7935 100644 --- a/drivers/dma/imx-sdma.c +++ b/drivers/dma/imx-sdma.c @@ -1718,8 +1718,8 @@ static void sdma_issue_pending(struct dma_chan *chan) #define SDMA_SCRIPT_ADDRS_ARRAY_SIZE_V1 34 #define SDMA_SCRIPT_ADDRS_ARRAY_SIZE_V2 38 -#define SDMA_SCRIPT_ADDRS_ARRAY_SIZE_V3 41 -#define SDMA_SCRIPT_ADDRS_ARRAY_SIZE_V4 42 +#define SDMA_SCRIPT_ADDRS_ARRAY_SIZE_V3 45 +#define SDMA_SCRIPT_ADDRS_ARRAY_SIZE_V4 46 static void sdma_add_scripts(struct sdma_engine *sdma, const struct sdma_script_start_addrs *addr) diff --git a/include/linux/platform_data/dma-imx-sdma.h b/include/linux/platform_data/dma-imx-sdma.h index 30e676b..e12d2e8 100644 --- a/include/linux/platform_data/dma-imx-sdma.h +++ b/include/linux/platform_data/dma-imx-sdma.h @@ -20,12 +20,12 @@ struct sdma_script_start_addrs { s32 per_2_firi_addr; s32 mcu_2_firi_addr; s32 uart_2_per_addr; - s32 uart_2_mcu_addr; + s32 uart_2_mcu_ram_addr; s32 per_2_app_addr; s32 mcu_2_app_addr; s32 per_2_per_addr; s32 uartsh_2_per_addr; - s32 uartsh_2_mcu_addr; + s32 uartsh_2_mcu_ram_addr; s32 per_2_shp_addr; s32 mcu_2_shp_addr; s32 ata_2_mcu_addr; @@ -52,6 +52,10 @@ struct sdma_script_start_addrs { s32 zcanfd_2_mcu_addr; s32 zqspi_2_mcu_addr; s32 mcu_2_ecspi_addr; + s32 mcu_2_sai_addr; + s32 sai_2_mcu_addr; + s32 uart_2_mcu_addr; + s32 uartsh_2_mcu_addr; /* End of v3 array */ s32 mcu_2_zqspi_addr; /* End of v4 array */ -- 2.7.4
