[PATCH v2 5/5] mmc: dw_mmc: Set timeout to max upon resume

2013-07-09 Thread Doug Anderson
The TMOUT register is initted to 0x at probe time but isn't initted after suspend/resume. Add an init of this value. No problems were observed without this (it will also get initted in __dw_mci_start_request if there is data to send), but it makes the register dump before and after

[PATCH v2 1/5] mmc: dw_mmc: Invalidate cache of current_speed after suspend/resume

2013-07-09 Thread Doug Anderson
The dw_mmc driver keeps a cache of the current slot-clock in order to avoid doing a whole lot of work every time set_ios() is called. However, after suspend/resume the register values are bogus so we need to ensure that the cached value is invalidated. In many cases we got by without this since

[PATCH v2 4/5] mmc: dw_mmc: Always setup the bus after suspend/resume

2013-07-09 Thread Doug Anderson
After suspend/resume all of the dw_mmc registers are reset to defaults. We restore most of them, but specifically don't setup the clock registers after resume unless we've got a powered card. Things still work because the core will eventually call set_ios() and we'll set things up. There

This series of patches addresses some suspend/resume problems with dw_mmc on exynos platforms. Since suspend/resume is not fully working on ToT Linux (3.10) on exynos5250-snow, this series was tested against the current ToT ChromeOS 3.8 tree. I have confirmed basic booting and eMMC / SD card

On some devices (like exynos5420) the dw_mmc controller may be in a strange state after we wake up from sleep. Add callbacks to allow for dealing with these quirks. We use the _noirq versions of the callbacks since in the case of exynos5420 the strange state caused interrupts to fire so we need
