V3
----
[01/12]: Changed function name from *_auto_cmd23_supported() to
*_auto_cmd23_required().
[02/12]: Set bit 24 and bit 28 of OCR within mmc_sd_get_cid(),
and only retry sending ACMD41 with bit 24 reset in case
signal voltage switch procedure fails.
[02/12]: Change (*rocr & 0x41000000) to ((*rocr & 0x41000000) ==
0x41000000) to check for both CCS and S18A to be set in
the response of ACMD41.
[02/12]: Change the condition if (err == -EAGAIN) to if (err), in
order to retry sending ACMD41 because of any error during
signal voltage switch procedure.
[02/12]: Add a new variable signal_voltage to struct mmc_ios,
which holds whether the request is to change to 1.8V or
3.3V signalling voltage.
[03/12]: Remove redundant code to find bus speed modes for SD2.0
and SD3.0 cards separately.
[03/12]: Change the variable names from uhs_* to sd3_* to make
them appropriate to the context of their usage.
[04/12]: Change variable names from *_set_drv_type to *_drv_type.
[04/12]: Set driver type even when the default driver type B is
used.
[04/12]: Clear bits 05-04 of Host Control 2 register before
setting the new driver strength.
[05/12]: Use sdhci_set_clock() to make sure the clock is stable
before re-enabling SD clock.
[06/12]: Initialize bus_speed and timing to 0 at the beginning of
sd_set_bus_speed_mode() to avoid compiler warning.
[07/12]: Initialize current_limit to 0 to avoid compiler warning.
[07/12]: Remove usage of get_max_current_180() and replace this
with MMC_CAP_MAX_CURRENT_*.
[07/12]: Set the current limit even for the default current limit
of 200mA.
[07/12]: Set the current limit only for SDR50, SDR104, and DDR50
UHS-I modes, otherwise set the default current limit.
[08/12]: Change mmc_*_ultrahighspeed() to mmc_sd_*_uhs().
[09/12]: Re-read Host Control 2 register before clearing
*_TUNED_CLK and *_EXEC_TUNING.
[09/12]: Make sdhci_execute_tuning() return 'int' rather than
'void' so that we can check for error conditions during
tuning failure.
[09/12]: Make sure to return 0 for controllers which provide
support for retuning even if tuning fails. For other
controllers, return error code.
[10/12]: Disable using Preset Value when a new card is inserted,
and enable its use only after a successfull UHS-I
initializaton.
[12/12]: Remove sdhci_start_retuning_timer() completely, and start
the re-tuning timer from within sdhci_execute_tuning()
the very first time it is executed.
V2
----
[01/12]: Make saved_abort_cmd part of struct sdhci_host rather
than global variable.
[01/12]: Clear SDHCI_USE_SDMA _iff_ SDHCI_USE_ADMA is set.
[01/12]: Set either Auto CMD23 or Auto CMD12, but not both, in
the Transfer Mode register.
[02/12]: Check host controller version before reading
SDHCI_CAPABILITIES_1.
[02/12]: Remove spinlock from sdhci_start_signal_voltage_switch
and use usleep_range() rather than mdelay().
[02/12]: Set S18R in OCR to 1 for all UHS-I modes.
[02/12]: NULL pointer check for start_signal_voltage_switch().
[02/12]: Set MMC_CAP_UHS_SDR50 if MMC_CAP_UHS_SDR104 is set.
[06/12]: Add checking for SDR25 in sd_set_bus_speed_mode().
[09/12]: Remove checking for MMC_SEND_TUNING_BLOCK within
sdhci_set_transfer_mode(), since cmd.data is set to
NULL inside sdhci_execute_tuning().
[11/12]: Correctly set clk to SDHCI_PROG_CLOCK_MODE when host
controller supports Programmable Clock Mode.
V1
----
The patches below add support for Host Controller v3.00 as per the
spec v3.00. It also adds support for UHS-I cards as per Physical
Layer Specification v3.01.
Thanks for review.
