commit c51d0ac59f ("mtd: nand: Move Samsung specific init/detection
logic in nand_samsung.c") introduced a regression for Samsung SLC NAND
chips. Prior to this commit chip->bits_per_cell was initialized by calling
nand_get_bits_per_cell() before using nand_is_slc().
With the offending commit this call is skipped, leaving
chip->bits_per_cell cleared to zero when the manufacturer specific
'.detect' function calls nand_is_slc() which in turn interprets
bits_per_cell != 1 as indication for an MLC chip.
The effect is that e.g. a K9F1G08U0F NAND chip is falsely detected as
MLC NAND with 4KiB page size rather than SLC with 2KiB page size.
Add a call to nand_get_bits_per_cell() before calling the .detect hook
function in nand_manufacturer_detect(), so that the nand_is_slc()
calls in the manufacturer specific code will return correct results.

commit 1b7bde6d65 ("net: fec: implement rx_copybreak to improve rx performance")
introduced a regression for i.MX28. The swap_buffer() function doing
the endian conversion of the received data on i.MX28 may access memory
beyond the actual packet size in the DMA buffer. fec_enet_copybreak()
does not copy those bytes, so that the last bytes of a packet may be
filled with invalid data after swapping.
This will likely lead to checksum errors on received packets.
E.g. when trying to mount an NFS rootfs:
UDP: bad checksum. From 192.168.1.225:111 to 192.168.100.73:44662 ulen 36

Fix this by using the _cansleep() variant of gpio_get_value().

When trying to use the matrix-keypad driver with GPIO drivers that
require nested irq handlers (e.g. I2C GPIO adapters like PCA9554),
request_irq() fails because the GPIO driver requires a threaded
interrupt handler.
Use request_any_context_irq() to be able to use any GPIO driver as
keypad driver.

commit 257462dbf3 ("pwm-backlight: switch to gpiod interface")
introduced a regression leading to acquiring a bogus GPIO-0 when
configured from DT without an 'enable-gpios' property.
The driver will happily accept the 0 initialized 'enable_gpio' member
of the struct platform_pwm_backlight_data as valid gpio number, and
request this GPIO as enable pin. In case of multiple driver instances,
the second will fail to register with the error message:
pwm-backlight backlight1.23: failed to request GPIO#0: -16
Fix this by setting enable_gpio in the pdata struct to -EINVAL.

With a flash-based BBT there is no reason to move the Factory Bad
Block Marker from the data area buffer (to where it is mapped by the
GPMI NAND controller) to the OOB buffer. Thus, make this feature
configurable via DT. This is required for the Ka-Ro electronics
platforms.
In the original code 'this->swap_block_mark' was synonymous with
'!GPMI_IS_MX23()', so use the latter at the relevant places.

This patch adds support for the Ka-Ro electronics GmbH TX6 modules.
There are five distinct module types with either i.MX6Q or i.MX6DL and
LVDS or LCD display interface and one DTS file for a complete system
with an i.MX6DL based TX6 module and a baseboard mounted on the back
of a display (imx6dl-tx6dl-comtft.dts).

commit 943c13971c "usb: musb: dsps: implement ->set_mode()"
should have made it possible to use the driver with boards that have
the USBID pin unconnected. This doesn't actually work, since the
driver uses the wrong base address to access the mode register.
Furthermore it uses different base addresses in different places to
access the same register (phy_utmi).
