mmc: dw_mmc: remove DW_MCI_QUIRK_BROKEN_CARD_DETECTION quirk

2016-02-29T10:03:10+00:00

dw_mmc already use mmc_of_parse to get "broken-cd" property,
but it considered "broken-cd" to be a quirk in its driver. We
don't need this quirk here, and just take what we need from
mmc->caps.

mmc: tmio: refactor set_clock a little

2016-02-29T10:03:06+00:00

Some of the indentation made the code awful to read. Fix that. Also,
introduce defines instead of magic hex values. Note that this includes
one change: We mask out know 0xff instead of 0x1ff. But 0x100 has always
been the clock enable bit. It doesn't make any sense to set it depending
on the clock calculation. Update copyright notices, too. I'll be working
on those files some more in the future.

mmc: core: remove the MMC_DATA_STREAM flag

2016-02-29T10:03:02+00:00

It's not set to MMC_DATA_STREAM anywhere.
It seems that it had been used with CMD11/CMD20.
But according to Spec, CMD11/CMD20 are obsolete command.

mmc: dw_mmc: use resource_size_t to store physical address

2015-12-22T10:32:19+00:00

The dw_mmc driver stores the physical address of the MMIO registers
in a pointer, which requires the use of type casts, and is actually
broken if anyone ever has this device on a 32-bit SoC in registers
above 4GB. Gcc warns about this possibility when the driver is built
with ARM LPAE enabled:

mmc/host/dw_mmc.c: In function 'dw_mci_edmac_start_dma':
mmc/host/dw_mmc.c:702:17: warning: cast from pointer to integer of different size
  cfg.dst_addr = (dma_addr_t)(host->phy_regs + fifo_offset);
                 ^
mmc/host/dw_mmc-pltfm.c: In function 'dw_mci_pltfm_register':
mmc/host/dw_mmc-pltfm.c:63:19: warning: cast to pointer from integer of different size
  host->phy_regs = (void *)(regs->start);

This changes the code to use resource_size_t, which gets rid of the
warning, the bug and the useless casts.

mmc: core: Refactor code to register the MMC PM notifier

2015-12-22T10:32:04+00:00

Instead of checking for "#ifdef" directly in the code, let's invent a pair
of mmc core functions to deal with register/unregister the MMC PM notifier
block. Implement stubs for these functions when CONFIG_PM_SLEEP is unset,
as in that case the PM notifiers isn't used.

mmc: mmc: extend the mmc_send_tuning()

2015-10-27T09:38:41+00:00

The mmc_execute_tuning() has already prepared the opcode,
there is no need to prepare it again at mmc_send_tuning(),
and, there is a BUG of mmc_send_tuning() to determine the opcode
by bus width, assume eMMC was running at HS200, 4bit mode,
then the mmc_send_tuning() will overwrite the opcode from CMD21
to CMD19, then got error.

in addition, extend an argument of "cmd_error" to allow getting
if there was cmd error when tune response.
