If wakeup-source flag is set in host dts node, parse EAI information from SDIO CCCR interrupt externsion segment for in-band wakeup. If async interrupt is supported by SDIO card then enable it and set enable_async_irq flag in sdio_cccr structure to 1. The parse flow is implemented in sdio_read_cccr(). Reviewed-by:

Extend interrupts and pinctrls for SDIO wakeup interrupt feature. This feature allow SDIO devices alarm asynchronous interrupt to host even when host stop providing clock to SDIO card. An extra wakeup interrupt and pinctrl states for SDIO DAT1 pin state switching are required in this scenario. Reviewed-by:

This reverts three commits: 1. Revert "mmc: sdhci-msm: Add compatible string check for sdx65" This reverts commit 95370684. 2. Revert "mmc: sdhci-msm: Add compatible string check for sm8150" This reverts commit 5acd6adb. 3. Revert "mmc: sdhci-msm: Add SoC specific compatibles" This reverts commit 466614a9. The oldest commit 466614a9 ("mmc: sdhci-msm: Add SoC specific compatibles") did not specify what benefits such multiple compatibles bring, therefore assume there is none. On the other hand such approach brings a lot of churn to driver maintenance by expecting commit for every new compatible, even though it is already covered by the fallback. There is really no sense in duplicating of_device_id for each variant, which is already covered by generic compatible fallback qcom,sdhci-msm-v4 or qcom,sdhci-msm-v5. Signed-off-by:

The entries in arrays must have fixed order, so the bindings and Linux driver expecting various combinations of 'reg' addresses was never actually conforming to guidelines. The 'core' reg entry is valid only for SDCC v4 and lower, so disallow it in SDCC v5. SDCC v4 supports CQE and ICE, so allow them, even though the qcom,sdhci-msm-v4 compatible is used also for earlier SoCs with SDCC v2 or v3, so it is not entirely accurate. Signed-off-by:

We need runtime PM enabled early in probe before sdhci_setup_host() for sdhci_omap_set_capabilities(). But on the first runtime resume we must not call sdhci_runtime_resume_host() as sdhci_setup_host() has not been called yet. Let's check for an initialized controller like we already do for context restore to fix a lockdep warning. Fixes: f433e8aa ("mmc: sdhci-omap: Implement PM runtime functions") Reported-by:

Convert the Samsung SoC SDHCI Controller bindings to DT schema. The original bindings were quite old and incomplete, so add during conversion typical (already used) properties like reg, clocks, interrupts. The bindings were not precising the clocks, although the upstream DTS and Linux driver were expecting bus clocks in certain patterns in any order. Document the status quo even though it is not a proper approach for bindings. Signed-off-by:

If we reset because of an error, we need to preserve values for the clock frequency. Otherwise, glitches may be seen on the bus. To achieve that, we introduce a 'preserve' parameter to the reset function and the IP core specific reset callbacks to handle everything accordingly. Reported-by:

Some functions of the bitmap API take advantage of the fact that a bitmap is an array of long. So, to make sure this assertion is correct, allocate bitmaps with bitmap_zalloc() instead of kzalloc()+hand-computed number of bytes. While at it, also use bitmap_free() instead of kfree() to keep the semantic. Fixes: 0ab30494 ("memstick: add support for legacy memorysticks") Signed-off-by:

Due to flaws in hardware design, GL9763E takes long time to exit from L1 state. The I/O performance will suffer severe impact if it often enter and exit L1 state during I/O requests. To improve I/O read/write performance and take battery life into account, let's turn on GL9763E L1 negotiation before entering runtime suspend and turn off GL9763E L1 negotiation while executing runtime resume. That is to say, GL9763E will not enter L1 state when executing I/O requests and enter L1 state when PCIe bus idle. Signed-off-by:
