[PATCH 1/2] mmc: add support for H/W clock gating of SD controller This code extends software clock gating in the MMC layer by adding the ability to indicate that the SD controller supports hardware clock gating. Hardware clock gating is enabled by setting the MMC capability MMC_CAP_HW_CLOCK_GATING in the SD driver. eg: host->mmc->caps |= MMC_CAP_HW_CLOCK_GATING The approach follows the suggestion of Nico Pitre. SD/MMC/eMMC cards use dynamic clocks SDIO uses continuous clocks to properly detect SDIO card interrupts The code has been tested using marvell linux and linux-next for MMP2. The Marvell pxa controllers support H/W clock gating. [PATCH 2/2] sdhci: sdhci-pxa: add support for hardware clock gating callback enable controller caps to support h/w clock gating-- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
