2022-03-16rockchip: sdhci: Add HS400 Enhanced Strobe support for RK3568Alper Nebi Yasak
On RK3568, a register bit must be set to enable Enhanced Strobe. However, it appears that the address of this register may differ from vendor to vendor and should be read from the underlying MMC IP. Let the Rockchip SDHCI driver read this address and set the relevant bit when Enhanced Strobe configuration is requested. The IP uses a custom mode select value (0x7) for HS400, use that instead of the common but non-standard SDHCI_CTRL_HS400 value (0x5). Also add some necessary DLL_STRBIN and DLL_TXCLK configuration for HS400. Additionally, a bit signifying that the connected hardware is an eMMC chip must be set to enable Data Strobe for HS400 and HS400ES modes. Also make the driver set this bit as appropriate. This is partly ported from Linux's Synopsys DWC MSHC driver which happens to be the underlying IP. (drivers/mmc/host/sdhci-of-dwcmshc.c in Linux tree).

On RK3399, a register bit must be set to enable Enhanced Strobe. Let the Rockchip SDHCI driver set it when Enhanced Strobe configuration is requested. However, having it set makes the lower-speed modes stop working and makes reinitialization fail, so let it be unset as needed in set_control_reg().

2022-03-16mmc: xenon_sdhci: remove wait_dat0 SDHCI OPRobert Marko
Generic SDHCI driver received support for checking the busy status by polling the DAT[0] level instead of waiting for the worst MMC switch time. Unfortunately, it appears that this does not work for Xenon controllers despite being a part of the standard SDHCI registers and the Armada 3720 datasheet itself telling that BIT(20) is useful for detecting the DAT[0] busy signal. I have tried increasing the timeout value, but I have newer managed to catch DAT_LEVEL bits change from 0 at all. This issue appears to hit most if not all SoC-s supported by Xenon driver, at least A3720, A8040 and CN9130 have non working eMMC currently. So, until a better solution is found drop the wait_dat0 OP for Xenon. I was able to only test it on A3720, but it should work for others as well.

2022-03-16mmc: fsl_esdhc_imx: use VENDORSPEC_FRC_SDCLK_ON when necessaryHaibo Chen
After commit f132aab40327 ("Revert "mmc: fsl_esdhc_imx: use VENDORSPEC_FRC_SDCLK_ON to control card clock output""), it involve issue in mmc_switch_voltage(), because of the special design of usdhc. For FSL_USDHC, it do not implement VENDORSPEC_CKEN/PEREN/HCKEN/IPGEN, these are reserved bits(Though RM contain the definition of these bits, but actually internal IC logic do not implement, already confirm with IC team). Instead, use VENDORSPEC_FRC_SDCLK_ON to gate on/off the card clock output. Here is the definition of this bit in RM: [8] FRC_SDCLK_ON Force CLK output active Do not set this bit to 1 unless it is necessary. Also, make sure that this bit is cleared when uSDHC’s clock is about to be changed (frequency change, clock source change, or delay chain tuning). 0b - CLK active or inactive is fully controlled by the hardware. 1b - Force CLK active In default, the FRC_SDCLK_ON is 0. This means, when there is no command or data transfer on bus, hardware will gate off the card clock. But in some case, we need the card clock keep on. Take IO voltage 1.8v switch as example, after IO voltage change to 1.8v, spec require gate off the card clock for 5ms, and gate on the clock back, once detect the card clock on, then the card will draw the dat0 to high immediately. If there is not clock gate off/on behavior, some card will keep the dat0 to low level. This is the reason we fail in mmc_switch_voltage(). To fix this issue, and concern that this is only the fsl usdhc hardware design limitation, set the bit FRC_SDCLK_ON in the beginning of the wait_dat0() and clear it in the end. To make sure the 1.8v IO voltage switch process align with SD specification. For standard tuning process, usdhc specification also require the card clock keep on, so also add these behavior in fsl_esdhc_execute_tuning().

2022-03-15spi: dw: Actually mask interruptsSean Anderson
The designware spi driver unconditionally uses polling. The comment to spi_hw_init() also states that the function should disable interrupts. According to the DesignWare DW_apb_ssi Databook, value 0xff in IMR enables all interrupts. Since we want to mask all interrupts write 0x0 instead. On the canaan k210 board, pressing the reset button twice to reset the board will run u-boot. If u-boot boots Linux without having SPI interrupts masked, Linux will hang as soon as interrupts are enabled, because of an interrupt storm. Properly masking the SPI interrupts in u-boot allows us to successfully boot Linux, even after resetting the board.

2022-03-14rockchip: sdhci: Fix RK3399 eMMC PHY power cyclingAlper Nebi Yasak
The Rockchip RK3399 eMMC PHY has to be power-cycled while changing its clock speed to some higher speeds. This is dependent on the desired SDHCI clock speed, and it looks like the PHY should be powered off while setting the SDHCI clock in these cases. Commit ac804143cfd1 ("mmc: rockchip_sdhci: add phy and clock config for rk3399") attempts to do this in the set_ios_post() hook by setting the SDHCI clock once more while the PHY is turned off/on as necessary, as the SDHCI framework does not provide a way to override how it sets its clock. However, the commit breaks reinitializing the eMMC on a few boards including chromebook_kevin and reportedly ROCKPro64. This patch reworks the power cycling to utilize the SDHCI framework slightly better (using the set_control_reg() hook to power off the PHY and set_ios_post() hook to power it back on) which happens to fix the issue, at least on a chromebook_kevin.

Ethernet phy like dp83867 is using strapping resistors to setup PHY address. On Xilinx boards strapping is setup on wires which are connected to SOC where internal pull ups/downs influnce phy address. That's why there is a need to setup pins properly (via pinctrl driver for example) and then perform phy reset. I can be workarounded by reset gpio done for mdio bus but this is not working properly when multiply phys sitting on the same bus. That's why it needs to be done via ethernet-phy-id driver where dt binding has gpio reset per phy.

2022-03-08drivers: serial: Make sure we really return a serial deviceMark Kettenis
The stdout-path property in the device tree does not necessarily point at a serial device. On machines such as the Apple M1 laptops where the serial port isn't easy to access and users expect to see console output on the integrated display stdout-path may point at the device tree node for the framebuffer for example. If stdout-path does not point at a node for a serial device, the serial_check_stdout() will not find a bound device and will drop down into code that attempts to use lists_bind_fdt() to bind a device anyway. However, that fallback code does not check that the uclass of the device is UCLASS_SERIAL. So if stdout-path points at the framebuffer instead of the serial device it will return a UCLASS_VIDEO device. Since the code that calls this function expects the returned device to be a UCLASS_SERIAL device, U-Boot will crash as soon as it attempts to send output to the console. Add a check here to verify that the uclass of the bound device really is UCLASS_SERIAL. If it isn't, serial_check_stdout() will return an error and serial_find_console_or_panic() will use the serial device with sequence number 0 as the console and all is fine.

2022-03-08watchdog: rti_wdt: Add 10% safety margin to clock frequencyJan Kiszka
When running against RC_OSC_32k, the watchdog may suffer from running faster than expected, expiring earlier. The Linux kernel adds a 10% margin to the timeout calculation by slowing down the read clock rate accordingly. Do the same here, also to have comparable preset values for both drivers. Along this, fix the name of the local var holding to frequency - in Hz, not kHz. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Stefan Roese <sr@denx.de>
2022-03-08watchdog: armada_37xx: Probe driver also when watchdog is already runningPali Rohár
If Armada 37xx watchdog is started before U-Boot then CNTR_CTRL_ACTIVE bit is set, U-Boot armada-37xx-wdt.c driver fails to initialize and so U-Boot is unable to use or kick this watchdog. Do not check for CNTR_CTRL_ACTIVE bit and always initialize watchdog. Same behavior is implemented in Linux kernel driver. This change allows to activate watchdog in firmware which loads U-Boot.

Since commit 492ee6b8d0e7 ("watchdog: wdt-uclass.c: handle all DM watchdogs in watchdog_reset()"), all the watchdog are started when the config WATCHDOG_AUTOSTART. To avoid a binary choice none/all, a property u-boot,noautostart may be added in the watchdog node of the u-boot device tree to not autostart this watchdog.

The Aspeed GPIO driver supports the GPIO controllers found in the AST2400, AST2500 and AST2600 BMC SoCs. The implementation is a cut-down copy of the upstream Linux kernel driver, adapted for u-boot. Signed-off-by: Andrew Jeffery <andrew@aj.id.au>
2022-03-07arm: mmc: Add "ti, am335-sdhci" compatible for TI's omap_hsmmc driverLukasz Majewski
In the Linux kernel (v5.16) for this SoC there are two separate drivers - namely sdhci-omap.c and omap_hsmmc.c which have separate set of compatibles. The U-Boot's drivers/mmc/omap_hsmmc.c driver supports both eMMC and SD devices - hence the compatible for SDHCI can be added. After this change the am335x DTS description can be easier ported from Linux kernel. Signed-off-by: Lukasz Majewski <lukma@denx.de> Reviewed-by: Jaehoon Chung <jh80.chung@samsung.com>
