This commit adds SD/MMC clocks, and provides .set/get_rate callbacks for SD/MMC device present on Actions OWL S700 SoCs.

Signed-off-by: Amit Singh Tomar amittomer25@gmail.com --- Changes since v3: * No change. Changes since v2: * Fixed the weird div assignment. * Moved the clock bit for SD from header file to driver file. * Removed "< 0" part while comparing unsigned. Changes since previous version: * Removed rate *= 2 as this just overclocks. * Separated the divide by 128 bit from divider value. * Provided the separate routine to get sd parent rate based on bit 9. * Removed unnecessary initialization. --- drivers/clk/owl/clk_owl.c | 73 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 73 insertions(+)

This commit adds support for MMC controllers found on Actions OWL SoC platform(S700/S900).

Signed-off-by: Amit Singh Tomar amittomer25@gmail.com --- Changes since v3: * Re-based to latest master (2ad8d0cb950da)

There are some "dm: treewide" changes have been made since v3, for instance: dm: treewide: Rename ofdata_to_platdata() to of_to_plat() It is addressed in v4 for this MMC driver.

* Used setbits_le32( wherever possible. * Properly write the OWL_REG_SD_BUF_SIZE register. * Updated the mode handling as suggested by Ander: mode = 0; if (cmd->resp_type != MMC_RSP_NONE) cmd_rsp_mask = OWL_SD_STATE_CLNR | OWL_SD_STATE_CRC7ER;

if (md->resp_type == MMC_RSP_R1) { .... (always assign to "mode") * Properly handled the unsupported SD clock rate. * Wait for DMA transfer to complete before stoping the DMA. Changes since v2: * Progammed read/write delays as suggested by Jaehoon, its more readable now. * Updated commit message and source file to reflect it supports S900 as well. * Updated SD_DMA_CHANNEL macro to include channel offset. * Checked the command response Error based on SDC STATU register bits. * Replaced switch/case with if/else to correlate with MMC_RSP_Rx bitmask values, as suggested by Andre. * Introduced clk_disable based on mmc->clk_disable flag. * Guarded the clk_set_rate under if statment to avoid reprogramming the rate. * Fetched the DRQ number from using args.args[0]. Changes since previous version * Corrected block count to 512. * Changed the command timeout value to 30ms. * Used readl_poll_timeout. * Read DMA parameters from DT instead of hardcoding it. * Reduced number of arguments passed to own_dma_cofig. * Removed debug leftover. * Used mmc_of_parse(). --- drivers/mmc/Kconfig | 7 + drivers/mmc/Makefile | 1 + drivers/mmc/owl_mmc.c | 408 ++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 416 insertions(+) create mode 100644 drivers/mmc/owl_mmc.c
