Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/geert/linux-m68k

Pull m68k update from Geert Uytterhoeven.

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/geert/linux-m68k:
  m68k: Remove inline strlen() implementation
  m68k/atari: USB - add platform devices for EtherNAT/NetUSBee ISP1160 HCD
  m68k: Implement ndelay() based on the existing udelay() logic
  m68k/atari: EtherNAT - add interrupt chip definition for CPLD interrupts
  m68k/atari: EtherNEC - add platform device support
  m68k/atari: EtherNAT - platform device and IRQ support code
  m68k/atari: use dedicated irq_chip for timer D interrupts
  m68k/atari: ROM port ISA adapter support
  m68k: Add missing cmpxchg64() if CONFIG_RMW_INSNS=y

help
This option enables support for the ROM port ISA adapter used to
operate ISA cards on Atari. Only 8 bit cards are supported, and
no interrupt lines are connected.
The only driver currently using this adapter is the EtherNEC
driver for RTL8019AS based NE2000 compatible network cards.

Say Y to include support for the EtherNEC network adapter for the
ROM port. The driver works by polling instead of interrupts, so it
is quite slow.
This driver also suppports the ethernet part of the NetUSBee ROM
port combined Ethernet/USB adapter.
To compile the actual ethernet driver, choose Y or M in for the NE2000

/*
* Atari ROM port (cartridge port) ISA adapter, used for the EtherNEC NE2000
* network card driver.
* The ISA adapter connects address lines A9-A13 to ISA address lines A0-A4,
* and hardwires the rest of the ISA addresses for a base address of 0x300.
*
* Data lines D8-D15 are connected to ISA data lines D0-D7 for reading.
* For writes, address lines A1-A8 are latched to ISA data lines D0-D7
* (meaning the bit pattern on A1-A8 can be read back as byte).
*
* Read and write operations are distinguished by the base address used:
* reads are from the ROM A side range, writes are through the B side range
* addresses (A side base + 0x10000).
*
* Reads and writes are byte only.
*
* 16 bit reads and writes are necessary for the NetUSBee adapter's USB
* chipset - 16 bit words are read straight off the ROM port while 16 bit
* reads are split into two byte writes. The low byte is latched to the
* NetUSBee buffer by a read from the _read_ window (with the data pattern
* asserted as A1-A8 address pattern). The high byte is then written to the
* write range as usual, completing the write cycle.
