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, }, }; // </smpl> Signed-off-by: NLars-Peter Clausen <lars@metafoo.de> Signed-off-by: NChris Ball <cjb@laptop.org>

由 Giuseppe CAVALLARO 提交于
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).

When we can't configure the dma channel we want to fall back to PIO. We do this by setting host->do_dma to zero. This does not work as do_dma is used to see whether dma can be used for the current transfer. Instead, we have to set host->dma to NULL.

In dw_mmc 2.40a spec, Data register's offset is changed. Before we used Data register offset 0x100. but if somebody uses a 2.40a controller, we must use 0x200 for Data register.

This patch adds support for the power off notify feature, available in eMMC 4.5 devices. If the host has support for this feature, then the mmc core will notify the device by setting the POWER_OFF_NOTIFICATION byte in the extended csd register with a value of 1 (POWER_ON). For suspend mode short timeout is used, whereas for the normal poweroff long timeout is used.

Ths patch allows runtime PM for sdhci-pci, runtime suspending after inactivity of 50ms and ensuring runtime resume before SDHC registers are accessed. During runtime suspend, interrupts are masked. The host controller state is restored at runtime resume. For Medfield, the host controller's card detect mechanism is supplanted by an always-on GPIO which provides for card detect wake-up.
