* mmc: sdhci-of-dwcmshc: Re-enable support for the BlueField-3 SoCLiming Sun2022-08-151-2/+14
| | | | | | | | | | | | | | | | | | The commit 08f3dff799d4 (mmc: sdhci-of-dwcmshc: add rockchip platform support") introduces the use of_device_get_match_data() to check for some chips. Unfortunately, it also breaks the BlueField-3 FW, which uses ACPI. To fix the problem, let's add the ACPI match data and the corresponding quirks to re-enable the support for the BlueField-3 SoC.

* mmc: mtk-sd: Clear interrupts when cqe off/disableWenbin Mei2022-08-151-0/+6
| | | | | | | | | | | | | | | | | Currently we don't clear MSDC interrupts when cqe off/disable, which led to the data complete interrupt will be reserved for the next command. If the next command with data transfer after cqe off/disable, we process the CMD ready interrupt and trigger DMA start for data, but the data complete interrupt is already exists, then SW assume that the data transfer is complete, SW will trigger DMA stop, but the data may not be transmitted yet or is transmitting, so we may encounter the following error: mtk-msdc 11230000.mmc: CMD bus busy detected.

This feature requires SDIO device support async IRQ function. With this feature, SDIO host can be awakened by SDIO card in suspend state, without additional pin. MSDC driver will time-share the SDIO DAT1 pin. During suspend, MSDC turn off clock and switch SDIO DAT1 pin to GPIO mode. And during resume, switch GPIO function back to DAT1 mode then turn on clock. Some device tree property should be added or modified in MSDC node to support SDIO eint IRQ. Pinctrls "state_eint" is mandatory. Since this feature depends on asynchronous interrupts, "wakeup-source", "keep-power-in-suspend" and "cap-sdio-irq" flags are necessary, and the interrupts list should be extended(the interrupt named with sdio_wakeup): &mmcX { ... interrupt-names = "msdc", "sdio_wakeup"; interrupts-extended = <...>, <&pio xxx IRQ_TYPE_LEVEL_LOW>; ... pinctrl-names = "default", "state_uhs", "state_eint"; ... pinctrl-2 = <&mmc2_pins_eint>; ... cap-sdio-irq; keep-power-in-suspend; wakeup-source; ... }; Co-developed-by: Yong Mao <yong.mao@mediatek.com> Signed-off-by: Yong Mao <yong.mao@mediatek.com> Reviewed-by: Chaotian Jing <chaotian.jing@mediatek.com> Reviewed-by: AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com> Reviewed-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Axe Yang <axe.yang@mediatek.com> Link: https://lore.kernel.org/r/20220726062842.18846-4-axe.yang@mediatek.com Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>

Revert "mmc: sdhci-msm: Add SoC specific compatibles" This reverts commit 466614a9765c6fb67e1464d0a3f1261db903834b. The oldest commit 466614a9765c ("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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 72116B0 has improved SDIO controllers that allow the max clock rate to be increased from a max of 100MHz to a max of 150MHz. The driver will need to get the clock and increase it's default rate and override the caps register, that still indicates a max of 100MHz. The new clock will be named "sdio_freq" in the DT node's "clock-names" list. The driver will use a DT property, "clock-frequency", to enable this functionality and will get the actual rate in MHz from the property to allow various speeds to be requested.
