An average vub300 session with CONFIG_MMC_CLKGATE=y set prints repeated
lines in the form of:
[83083.620491] usb 1-1.4: SET_CLOCK_SPEED 48000kHz
[83083.629664] usb 1-1.4: SET_CLOCK_SPEED 0kHz
[root@xo ~]# dmesg | grep SET_CLOCK_SPEED | wc -l
203
So, change this from dev_info() to dev_dbg(). We

Hi Andrei.
I have some question..
In mmc_blk_issue_rw_rq() of block.c, there is the below code.
static int mmc_blk_issue_rw_rq(struct mmc_queue *mq, struct request *req)
{
struct mmc_blk_data *md = mq->data;
struct mmc_card *card = md->queue.card;
struct mmc_blk_request br

1. when f_init is zero, the SDHC can't work correctly, so f_min will replace it.
2. Before running get_cd recall function to detect if the card is present,
must make sure the power is up.

Add callback function sdhci_get_cd to detect the card.
In order to check if the card is present,
we will read the PRESENT STATE register and check the bit15.
