2019-10-15dm: core: device: switch off power domain after device removalAnatolij Gustschin
The power domain associated with a device is enabled when probing, but currently the domain remains enabled when the device is removed. Some boards started to disable power domains for selected devices via custom board_quiesce_devices(), but it doesn't work in many cases, i. e. because devices still can be accessed later in .remove() callback on behalf of dm_remove_devices_flags(). Utilize the DM core to power off the device power domain, but add a device flag to be able to selectively let the power domain enabled after device removal. This might be required for devices that must remain enabled when booting OS, i. e. serial console for debug output, etc. Signed-off-by: Anatolij Gustschin <agust@denx.de> Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com> Reviewed-by: Simon Glass <sjg@chromium.org>

2019-10-15dm: core: Allow for not controlling the power-domain by DM frameworkLokesh Vutla
In some remoteproc cases, enabling the power domain of the core will start running the core. In such cases image should be loaded before enabling the power domain. But the current DM framework enables the power-domain by default during probe. This is causing the remotecore to start and crash as there is no valid image loaded. In order to avoid this introduce a DM flag that doesn't allow for enabling/disabling the power-domain by DM framework.

2019-10-15dm: pinctrl: introduce PINCONF_RECURSIVE optionPatrick Delaunay
In the Linux pinctrl binding, the pin configuration nodes don't need to be direct children of the pin controller device (may be grandchildren for example). This behavior is managed with the pinconfig u-class which recursively bind all the sub-node of the pin controller. But for some binding (when pin configuration is only children of pin controller) that is not necessary. U-Boot can save memory and reduce the number of pinconf instance when this feature is deactivated (for arch stm32mp for example for SPL). This patch allows to control this feature with a new option CONFIG_PINCONF_RECURSIVE when it is possible for each individual pin controller device.

2019-10-11spi: bcm63xx_hsspi: Continue init when using no reset and fixed-clock.Kursad Oney
The Broadcom ARM implementations do not yet have a clock framework so one can use a fixed clock as the root clock of the hsspi block. The fixed clock does not have an "enable" routine, since it's always enabled. So when we hit this issue, getting an ENOSYS return, do not bail but continue initialization. Similarly the block might already have been out of reset, say, when we are booting from a SPI device. So if the reset signal is not configured in the device tree, do not bail out and instead skip deasserting the reset.

2019-10-10mmc: add a driver callback for power-cycleYann Gautier
Some MMC peripherals require specific power cycle sequence, where some registers need to be written between the regulator is turned off and then back on. This is the case for the MMC IP embedded in STM32MP1 SoC. In STM32MP157 reference manual [1], the power cycle sequence is: 1. Reset the SDMMC with the RCC.SDMMCxRST register bit. This will reset the SDMMC to the reset state and the CPSM and DPSM to the Idle state. 2. Disable the Vcc power to the card. 3. Set the SDMMC in power-cycle state. This will make that the SDMMC_D[7:0], SDMMC_CMD and SDMMC_CK are driven low, to prevent the card from being supplied through the signal lines. 4. After minimum 1ms enable the Vcc power to the card. 5. After the power ramp period set the SDMMC to the power-off state for minimum 1ms. The SDMMC_D[7:0], SDMMC_CMD and SDMMC_CK are set to drive “1”. 6. After the 1ms delay set the SDMMC to power-on state in which the SDMMC_CK clock will be enabled. 7. After 74 SDMMC_CK cycles the first command can be sent to the card. The step 3. cannot be handled by the current framework implementation. A new callback (host_power_cycle) is created, and called in mmc_power_cycle(), after mmc_power_off(). The incorrect power cycle sequence has shown some boot failures on STM32MP1 with some SD-cards, especially on cold boots when the input frequency is low (<= 25MHz). Those failures are no more seen with this correct power cycle sequence. [1] https://www.st.com/resource/en/reference_manual/DM00327659.pdf Signed-off-by: Yann Gautier <yann.gautier@st.com>

2019-10-10spl: dm_mmc: Initialize only the required mmc deviceLokesh Vutla
In SPL, all the available mmc devices gets initialized during boot. This might not work in cases where clocks are not available for certain mmc devices(other than boot device) and the support for enabling device might not be ready. Texas Instruments' K3 J721E device having a central system controller (dmsc) is one such example falling in this category. Below is the sequence for the failing scenario: - ROM comes up in SD mode and loads SPL by just initialing SD card. - SPL loads dmsc firmware from SD Card. Since ROM has enabled SD, SPL need not enable the SD, just need to re initialize the card. But SPL is trying to initialize other MMC instances which are in disabled state. Since dmsc firmware is not yet available, devices cannot be enabled. So in SPL, initialize only the mmc device that is needed.
