Rusty Russell 90ab5ee941 module_param: make bool parameters really bool (drivers & misc)
module_param(bool) used to counter-intuitively take an int.  In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.

It's time to remove the int/unsigned int option.  For this version
it'll simply give a warning, but it'll break next kernel version.

Shaohui Xie 3abc1e8042 mmc: sdhci: restore the enabled dma when do reset all
If dma is enabled, it'll be cleared when reset all is performed, this can
be observed on some platforms, such as P2041 which has a version 2.3
controller, but platform like P4080 which has a version 2.2 controller,
does not suffer this, so we will check if the dma is enabled, we should
restore it after reset all.

Lars-Peter Clausen 6601056a96 mmc: Remove redundant spi driver bus initialization
In ancient times it was necessary to manually initialize the bus field of an
spi_driver to spi_bus_type. These days this is done in spi_driver_register(),
so we can drop the manual assignment.

The patch was generated using the following coccinelle semantic patch:
// <smpl>
@@
identifier _driver;
@@
struct spi_driver _driver = {
	.driver = {
-		.bus = &spi_bus_type,
	},
};

Giuseppe CAVALLARO df16219f36 mmc: debugfs: expose the SDCLK frq in sys ios
This patch is to expose the actual SDCLK frequency in
/sys/kernel/debug/mmcX/ios entry.

For example, if the max clk for a normal speed card is 20MHz this
is reported in /sys/kernel/debug/mmcX/ios.  Unfortunately the actual
SDCLK frequency (i.e. Baseclock / divisor) is not reported at all:
for example, in that case, on Arasan HC, it should be 48/4=12 (MHz).
