[PATCH v4 0/2] mmc: core: hw_reset changes

[Johan Rudholm <johan.rudholm@axis.com>]

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?

v4:
 - Rebase onto next

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 (2):
  mmc: core: turn hw_reset into a bus_ops
  mmc: sd: add hw_reset callback
