584abc3775 tty: sdio_uart: Switch to the open/close helpers
Gets us proper tty semantics, removes some code and fixes up a few corner
case races (hangup during open etc)

0a68f64feb sdio_uart: Move the open lock
When we move to the tty_port logic the port mutex will protect open v close
v hangup. Move to this first in the existing open code so we have a bisection
point.

530646f469 sdio_uart: refcount the tty objects
The tty can go away underneath us, so we must refcount it. Do the naïve
implementation initially. We will worry about startup shortly.

b5849b1a82 sdio_uart: use tty_port
Add a tty_port object to the sdio uart. For the moment just begin using the
tty field of the port, as this is the critical one to clean up.

e707c35cbb tty_port: Move hupcl handling
Move the HUCPL handling from the end of close_port_start to the beginning
of close_port_end. What this actually does is change the ordering from

	port shutdown
	port->dtr_rts

to

	port->dtr_rts
	port shutdown

Some hardware drops the physical connection on shutdown so we must perform
the port operations before the shutdown.

68cb4f8e24 Serial: Do not read IIR in serial8250_start_tx when UART_BUG_TXEN
Do not read IIR in serial8250_start_tx when UART_BUG_TXEN

Reading the IIR clears some oustanding interrupts so it is not safe.
Instead, simply transmit immediately if the buffer is empty without
regard to IIR.

c934878cc0 Serial: pxa: work around Errata #75
Intel(R) PXA27x Processor Family Specification Update (Nov 2005)
says:

  E75. UART: Baud rate may not be programmed correctly on
       back-to-back writes.

  Problem:
  When programming the Divisor Latch registers, Low and High (DLL and
  DLH), with back-to-back writes, the second register write may not
  take effect. The result is an incorrect baud rate.

  Workaround:
  After programming the first Divisor Latch register, read and verify
  it before programming the second Divisor Latch register.

This was hit when changing the baud rate from 115200 to 9600 while
receiving characters at 9600 Bd.

And fixed indention of some comments nearby.

79a56ed0e1 nvram: Fix missing smp_lock.h in nvram
The bkl has been removed from nvram_llseek() and smp_lock.h was removed
because another patch in the same tree zapped the remaining usage of bkl
in the same file.  But this patch must have been excluded later, then we
still need the smp_lock.h headers for the bkl use in nvram_open().

This fixes the following build error:

  drivers/char/nvram.c: In function ‘nvram_open’:
  drivers/char/nvram.c:332: erreur: implicit declaration of function ‘lock_kernel’
  drivers/char/nvram.c:339: erreur: implicit declaration of function ‘unlock_kernel’
  make[2]: *** [drivers/char/nvram.o] Erreur 1
  make[1]: *** [drivers/char] Erreur 2
  make: *** [drivers] Erreur 2

Add support for the Analog Devices ADT7476 chip. This chip is largely
compatible with the ADT7473 and ADT7475, with additional features.
In particular, it has 5 voltage inputs instead of 2, and VID input
pins.

ebfaf1fbb6 hwmon: (adt7475) Voltage attenuators can be bypassed
It is possible to bypass the voltage attenuators on the +2.5V, Vccp,
+5V and +12V voltage monitoring inputs. This is useful to connect
other voltage channels than the ones the monitoring chip was
originally designed for. When this feature is enabled, we must not
include the scaling factors in our computations.
