* | | mmc: sdhci-pxav3: Remove checks for optional core clock in error/remove pathJisheng Zhang2015-01-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 63589e92c2d9 ("clk: Ignore error and NULL pointers passed to clk_{unprepare, disable}()") allows NULL or error pointer to be passed unconditionally. This patch is to simplify probe error and remove code paths. However, we reserve the core clock checks in runtime suspend/resume code because we want a little smaller latency.

The fix enables the clock twice, once by clk_prepare_enable() and another by pm_runtime_get_sync(), meaning that the clock will never be gated at runtime PM suspend. I observed the power consumption regression on Marvell BG2Q SoCs. In fact, the fix is not correct. There still be a very small window during which a runtime suspend might somehow occur after pm_runtime_enable() but before pm_runtime_get_sync(). This patch fixes all of the two problems by just incrementing the usage counter before pm_runtime_enable(). It also adjust the order of disabling runtime pm and storing the usage count in the error path to handle clock gating properly.

The page addresses are aligned to (align_sz), either for 4 or 8 bytes alignment, so that the aligned word resides wholly within a single page and can't cross the page boundary. So, the bounce buffer can't cross the page boundary too. That's why the warnings are never hit, and can be safely removed.

This change affects the Exynos variant, since it's the only one which support the dw_mmc's ->execute_tuning() callback. It's seems like dw_mmc internal logic expects failed data transfers to be ended using a stop command. Let the tuning requests also fall into this category, since there are data transfer involved.
