2021-08-06mmc: sdhci: Change prototype of set_delay to return errorsAshok Reddy Soma
set_delay() has return type as void. If there are any errors while setting tapdelay's it won't be able to return them. Change the prototype of set_delay() in sdhci_ops structure and return the errors from wherever it is called.

- SPI-NOR fix (Big Meng) - XMC XM25QH64C flash (Reto Schneider)
2021-08-03mtd: spi-nor: Mask out fast read if not requested in DTBin Meng
The DT bindings of "jedec,spi-nor" [1] defines "m25p,fast-read" property to indicate that "fast read" opcode can be used to read data from the chip instead of the usual "read" opcode. If this property is not present in DT, mask out fast read in spi_nor_init_params(). This change mirrors the same logic in spi_nor_info_init_params() in drivers/mtd/spi-nor/core.c in the Linux kernel v5.14-rc3.

ICH controller can only transfer a small number of bytes at once. Before commit 43c145b8b3ee, the logic happens to make sure data.nbytes is limited to slave->max_write_size but after commit 43c145b8b3ee data.nbytes is no longer limited because slave->max_read_size is not initialized with a valid number.

2021-08-01video: Add simple driver for ST-Ericsson MCDE with pre-configured displayStephan Gerhold
The U-Boot port for ST-Ericsson Ux500 is currently only used on the "stemmy" board, where U-Boot runs after firmware that already sets up a boot splash screen. This means that the display is already on and we can just continue using it for U-Boot. Add a simple driver that simplifies this by reading the display configuration (e.g. screen size, bpp) from the hardware registers. It also checks the configured "source synchronization" - for some displays (usually DSI command mode displays) we need to explicitly trigger a software sync. This is done through the video_sync() callback that triggers the sync and wait for completion.

2021-07-31arm64: a37xx: pinctrl: Correct PWM pins definitionsMarek Behún
The PWM pins on North Bridge on Armada 37xx can be configured into PWM or GPIO functions. When in PWM function, each pin can also be configured to drive low on 0 and tri-state on 1 (LED mode). The current definitions handle this by declaring two pin groups for each pin: - group "pwmN" with functions "pwm" and "gpio" - group "ledN_od" ("od" for open drain) with functions "led" and "gpio" This is semantically incorrect. The correct definition for each pin should be one group with three functions: "pwm", "led" and "gpio". Change the "pwmN" groups to support "led" function. Remove "ledN_od" groups. This cannot break backwards compatibility with older device trees: no device tree uses it since there is no PWM driver for this SOC yet. Also "ledN_od" groups are not even documented.

2021-07-30mmc: arm_pl180_mmci: Don't bind to all arm, primecell devicesStephan Gerhold
The arm,primecell compatible is used for lots of different types of devices, e.g. I2C, SPI, coresight, ... We really should not bind the MMC driver to all of them. Looking through the device trees in U-Boot there seems to be always a second compatible string for the pl180 device, either arm,pl180 (already listed) or arm,pl18x. Add the "arm,pl18x" compatible to the list but remove the generic "arm,primecell". Note that on Linux these compatibles cannot be found in drivers because AMBA/primecell devices are matched based on their peripheral ID instead of the compatible.
