* mmc: dw_mmc: fix the wrong Mask bit boundary for fifo_count bitJaehoon Chung2016-08-05-1/+1
| | | | | | | | | According to DesignWare TRM, FIFO_COUNT is bit[29:17]. If get the correct fifo_count value, it has to use the FIFO_MASK as 0x1FFF, not 0x1FF. Signed-off-by: Jaehoon Chung <jh80.chung@samsung.com> Reviewed-by: Ziyuan Xu <xzy.xu@rock-chips.com>
* dm: mmc: dwmmc: use the callback functions as staticJaehoon Chung2016-07-27-3/+0
| | | | | | | | | There are no places to call these functions. It should be used the callback function. Then it can be used as static functions. Signed-off-by: Jaehoon Chung <jh80.chung@samsung.com> Reviewed-by: Simon Glass <sjg@chromium.org>

* mmc: exynos_dw_mmc: use the exynos specific data structureJaehoon Chung2015-02-23-1/+1
| | | | | | | | Clksel value is exynos specific value. It removed "clksel_val" into dwmci_host and created the "dwmci_exynos_priv_data" structure for exynos specific data. Signed-off-by: Jaehoon Chung <jh80.chung@samsung.com>
* mmc: dw_mmc: Fix cache alignment issueMarek Vasut2014-10-06-1/+1
| | | | | | | | | | | | | | | | | | | | | | | The DMA descriptors used by the DW MMC block must be aligned to cacheline size, otherwise we are unable to properly flush/inval cache over them and we get data corruption. The reason I chose this approach of expanding the structure is because the driver allocates the descriptors in bulk. This approach does waste space by inserting slop inbetween the descriptors, but it makes access to the descriptors easy as the compiler does know the real size of the structure. It also makes cache operations easy, since the size of the structure is cache aligned and the structure start address is as well.

* mmc: Split mmc struct, rework mmc initialization (v2)Pantelis Antoniou2014-03-24-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The way that struct mmc was implemented was a bit of a mess; configuration and internal state all jumbled up in a single structure. On top of that the way initialization is done with mmc_register leads to a lot of duplicated code in drivers. Typically the initialization got something like this in every driver. struct mmc *mmc = malloc(sizeof(struct mmc)); memset(mmc, 0, sizeof(struct mmc); /* fill in fields of mmc struct */ /* store private data pointer */ mmc_register(mmc); By using the new mmc_create call one just passes an mmc config struct and an optional private data pointer like this: struct mmc = mmc_create(&cfg, priv); All in tree drivers have been updated to the new form, and expect mmc_register to go away before long. Changes since v1: * Use calloc instead of manually calling memset. * Mark mmc_register as deprecated. Signed-off-by: Pantelis Antoniou <panto@antoniou-consulting.com>
* MMC: DWMMC: Correct the CLKDIV register valueRajeshwari S Shinde2014-02-07-1/+1
| | | | | | | | | | | | | | | | | | This patch corrects the divider value written to CLKDIV register. Since SDCLKIN is divided inside controller by the DIVRATIO value set in the CLKSEL register, we need to use the same output clock value to calculate the CLKDIV value. as per user manual: cclk_in = SDCLKIN / (DIVRATIO + 1) Input parameter to mmc_clk is changed to dwmci_host, since we need the same to read DWMCI_CLKSEL register. This improves the read timing values for channel 0 on SMDK5250 from 0.288sec to 0.144sec Signed-off-by: Rajeshwari S Shinde <rajeshwari.s@samsung.com> Acked-by: Jaehoon Chung <jh80.chung@samsung.com> Signed-off-by: Pantelis Antoniou <panto@antoniou-consulting.com>
