After +looking at the code I saw I missed two tricks, this will force it off +after resume and will do better generally depending on what the last SD Card +packet was. + +Since bulk read packet is normally last action (which set the clock off even +without this) the old patch worked for normal cases. But after resume, the last +packet on the wire was not a bulk transfer and we didn't take care about the +clock then. + +Signed-off-by: Andy Green <andy@openmoko.com> +--- + drivers/mfd/glamo/glamo-mci.c | 6 +++--- + 1 files changed, 3 insertions(+), 3 deletions(-) + +diff --git a/drivers/mfd/glamo/glamo-mci.c b/drivers/mfd/glamo/glamo-mci.c +index 6729244..2318e6f 100644 +--- a/drivers/mfd/glamo/glamo-mci.c ++++ b/drivers/mfd/glamo/glamo-mci.c +@@ -619,12 +619,9 @@ done: + host->complete_what = COMPLETION_NONE; + host->mrq = NULL; + mmc_request_done(host->mmc, cmd->mrq); +- return; +- + bail: + /* stop the clock to card */ + __glamo_mci_fix_card_div(host, -1); +- return; + } + + static void glamo_mci_request(struct mmc_host *mmc, struct mmc_request *mrq) +@@ -690,6 +687,9 @@ static void glamo_mci_set_ios(struct mmc_host *mmc, struct mmc_ios *ios) + host->real_rate = __glamo_mci_set_card_clock(host, ios->clock, &div); + host->clk_div = div; + ++ /* stop the clock to card, because we are idle until transfer */ ++ __glamo_mci_fix_card_div(host, -1); ++ + if ((ios->power_mode == MMC_POWER_ON) || + (ios->power_mode == MMC_POWER_UP)) { + dev_info(&host->pdev->dev, +-- +1.5.6.5 + |
