Make the mmc_hw_reset routines more generic, so we can easily add a power cycle of SD cards as well. Also simplify the (e)MMC specific parts of the reset code.
As I don't have an eMMC device myself, much less one with a reset line, I'd be very happy if someone could help me test the code with an eMMC? Please have a look at the handling of bus_mode in mmc_set_initial_state(), we set it to MMC_BUSMODE_PUSHPULL also when powering off a device. If this is not OK, we'll just have to leave bus_mode out of it. v3: - Keep mmc_can_reset - Always set bus_mode = MMC_BUSMODE_PUSHPULL in mmc_set_initial_state() v2: - Call the new bus_ops member hw_reset instead of power_reset - Create mmc_set_initial_state and call it from mmc_mmc_hw_reset instead of mmc_power_up - Keep "mmc_hw_reset" naming Johan Rudholm (3): mmc: core: consistent handling of initial values mmc: core: turn hw_reset into a bus_ops mmc: sd: add hw_reset callback drivers/mmc/core/core.c | 99 ++++++++++++++++++----------------------------- drivers/mmc/core/core.h | 6 +++ drivers/mmc/core/mmc.c | 40 +++++++++++++++++++ drivers/mmc/core/sd.c | 13 ++++++ 4 files changed, 97 insertions(+), 61 deletions(-) -- 1.7.2.5 -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
