2020-05-29mmc: sdhci-of-arasan: Add support for Intel Keem BayWan Ahmad Zainie
Intel Keem Bay SoC eMMC/SD/SDIO controller is based on Arasan SD 3.0 / eMMC 5.1 host controller IP. However, it does not support 64-bit access as its AXI interface has 32-bit address ports.

2020-05-29mmc: sdhci-cadence: fix PHY writeVladimir Kondratiev
Accordingly to Cadence documentation, PHY write procedure is: 1. Software sets the PHY Register Address (HRS04[5:0]) and the PHY Write Data (HRS04[15:8]) fields. 2. Software sets the PHY Write Transaction Request (HRS04[24]) field to 1. 3. Software waits as the PHY Write Transaction Acknowledge (HRS04[26]) field is equal to 0. 4. Hardware performs the write transaction to PHY register where HRS04[15:8] is a data written to register under HRS04[5:0] address. 5. Hardware sets the PHY Transaction Acknowledge (HRS04[26]) to 1 when transaction is completed. 6. Software clears the PHY Write Transaction Request (HRS04[24]) to 1 after noticing that the PHY Write Transaction Acknowledge (HRS04[26]) field is equal to 1. 7. Software waits for the PHY Acknowledge Register (HRS04[26]) field is equal to 0. Add missing steps 3 and 7. Lack of these steps causes integrity errors detested by hardware.

2020-05-29mmc: sdio: Fix Cypress SDIO IDs macros in common include filePali Rohár
All macro names for SDIO device IDs are prefixed by vendor name to which device ID belongs. So for consistency add Broadcom string vendor prefix to all Cypress macro names as they belong to SDIO Broadcom vendor ID. Change also Cypress 43012 value from decimal do hexadecimal notation to be consistent with all other values.

dwc3_meson_g12a_usb2_init_phy() crashes with NULL pointer on an SM1 board (which uses the same USB setup as G12A) dereference as reported by the Kernel CI bot. This is because of the following call flow: dwc3_meson_g12a_probe priv->drvdata->setup_regmaps dwc3_meson_g12a_setup_regmaps priv->usb2_ports is still 0 so priv->u2p_regmap[i] will be NULL dwc3_meson_g12a_get_phys initializes priv->usb2_ports priv->drvdata->usb_init dwc3_meson_g12a_usb_init dwc3_meson_g12a_usb_init_glue dwc3_meson_g12a_usb2_init priv->drvdata->usb2_init_phy dwc3_meson_g12a_usb2_init_phy dereferences priv->u2p_regmap[i] Call priv->drvdata->setup_regmaps only after dwc3_meson_g12a_get_phys so priv->usb2_ports is initialized and the regmaps will be set up correctly. This fixes the NULL dereference later on.

2020-05-29opp: core: add regulators enable and disableKamil Konieczny
Add enable regulators to dev_pm_opp_set_regulators() and disable regulators to dev_pm_opp_put_regulators(). Even if bootloader leaves regulators enabled, they should be enabled in kernel in order to increase the reference count.

2020-05-29cpufreq: dt: Add support for interconnect bandwidth scalingGeorgi Djakov
In addition to clocks and regulators, some devices can scale the bandwidth of their on-chip interconnect - for example between CPU and DDR memory. Add support for that, so that platforms which support it can make use of it.

2020-05-29opp: Add sanity checks in _read_opp_key()Georgi Djakov
When we read the OPP keys, it would be nice to do some sanity checks of the values we get from DT and see if they match with the information that is populated in the OPP table. Let's pass a pointer of the table, so that we can do some validation.

2020-05-28clk: mediatek: assign the initial value to clk_init_data of mtk_muxWeiyi Lu
When some new clock supports are introduced, e.g. [1] it might lead to an error although it should be NULL because clk_init_data is on the stack and it might have random values if using without initialization. Add the missing initial value to clk_init_data.
