linux-toradex.git/drivers/serial, branch v2.6.33.2 Linux kernel for Apalis and Colibri modules serial: imx: fix NULL dereference Oops when pdata == NULL 2010-03-15T16:06:27+00:00 Baruch Siach baruch@tkos.co.il 2009-12-22T00:26:46+00:00 401c1e931d0f19af9eb25a310e1aeb187d03526d commit bbcd18d1b37413d25eaf4580682b1b8e4a09ff5e upstream. The platform code doesn't have to provide platform data to get sensible default behaviour from the imx serial driver. This patch does not handle NULL dereference in the IrDA case, which still requires a valid platform data pointer (in imx_startup()/imx_shutdown()), since I don't know whether there is a sensible default behaviour, or should the operation just fail cleanly.

commit bbcd18d1b37413d25eaf4580682b1b8e4a09ff5e upstream.

The platform code doesn't have to provide platform data to get sensible
default behaviour from the imx serial driver.

This patch does not handle NULL dereference in the IrDA case, which still
requires a valid platform data pointer (in imx_startup()/imx_shutdown()),
since I don't know whether there is a sensible default behaviour, or
should the operation just fail cleanly.

manipulate the handshake lines in order to control the radio modem's

Discovered in parallel with more testing and analysis by Kees Schoenmakers
as follows:

I ran into an NetMos 9835 serial pci board which behaves a little
different than the standard.  This type of expansion board is very common.

"Standard" 8250 compatible devices clear the 'UART_LST_TEMT" bit together
with the "UART_LSR_THRE" bit when writing data to the device.

The NetMos device does it slightly different

I believe that the TEMT bit is coupled to the shift register.  The problem
is that after writing data to the device and very quickly after that one
does call serial8250_tx_empty, it returns the wrong information.

My patch makes the test more robust (and solves the problem) and it does
not affect the already correct devices.

Alan:

  We may yet need to quirk this but now we know which chips we have a
  way to do that should we find this breaks some other 8250 clone with
  dodgy THRE.

Perform a tricky suspend/resume even with no_console_suspend.

With no_console_suspend, kernel skips serial port suspend/resume and the
serial hardware may remain in undefined state after resume. It actually
happens on devices that don't have BIOS that handle serial
initialization. It makes impossible to use serial console after resume.

Devices affected by this problem include:
Sharp Zaurus devices
Several PXA based ARM embedded boards

The patch does:
- Save the hardware state
- Perform buffer flush in time of its suspend call
- Tell the driver that port is suspended
- But still accept new data
- And keep console hardware in state that allows to send them

It allows to capture late console messages without breaking console
after resume.

This is just a resend of a patch discussed in these threads, as the
patch was not yet applied.

serial: 8250_pnp: use wildcard for serial Wacom tablets 2010-01-20T23:03:27+00:00 Matthew Garrett mjg@redhat.com 2009-12-09T20:31:37+00:00 6d34855d9aa281f72c533ecb827405139d1b0fe9 Wacom claims that the WACF namespace will always be devoted to serial Wacom tablets. Remove the existing entries and add a wildcard to avoid having to update the kernel every time they add a new device.
