* tty/serial: at91: remove unused open/close hooksRichard Genoud2014-02-28
| | | | | | | | | commit 95e629b761ce36996d1befe2824d5346b5a220b9 removed the use of board specific hooks in serial_at91.h, so now, the open/close hook are just dead code. Signed-off-by: Richard Genoud <richard.genoud@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

* tty: Set correct tty name in 'active' sysfs attributeHannes Reinecke2014-02-28
| | | | | | | | | | | | | | | | | | | | | | | | The 'active' sysfs attribute should refer to the currently active tty devices the console is running on, not the currently active console. The console structure doesn't refer to any device in sysfs, only the tty the console is running on has. So we need to print out the tty names in 'active', not the console names. There is one special-case, which is tty0. If the console is directed to it, we want 'tty0' to show up in the file, so user-space knows that the messages get forwarded to the active VT. The ->device() callback would resolve tty0, though. Hence, treat it special and don't call into the VT layer to resolve it (plymouth is known to depend on it).

* tty: Fix low_latency BUGPeter Hurley2014-02-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The user-settable knob, low_latency, has been the source of several BUG reports which stem from flush_to_ldisc() running in interrupt context. Since 3.12, which added several sleeping locks (termios_rwsem and buf->lock) to the input processing path, the frequency of these BUG reports has increased. Note that changes in 3.12 did not introduce this regression; sleeping locks were first added to the input processing path with the removal of the BKL from N_TTY in commit a88a69c91256418c5907c2f1f8a0ec0a36f9e6cc, 'n_tty: Fix loss of echoed characters and remove bkl from n_tty' and later in commit 38db89799bdf11625a831c5af33938dcb11908b6, 'tty: throttling race fix'. Since those changes, executing flush_to_ldisc() in interrupt_context (ie, low_latency set), is unsafe. However, since most devices do not validate if the low_latency setting is appropriate for the context (process or interrupt) in which they receive data, some reports are due to misconfiguration. Further, serial dma devices for which dma fails, resort to interrupt receiving as a backup without resetting low_latency. Historically, low_latency was used to force wake-up the reading process rather than wait for the next scheduler tick. The effect was to trim multiple milliseconds of latency from when the process would receive new data. Recent tests [1] have shown that the reading process now receives data with only 10's of microseconds latency without low_latency set. Remove the low_latency rx steering from tty_flip_buffer_push(); however, leave the knob as an optional hint to drivers that can tune their rx fifos and such like. Cleanup stale code comments regarding low_latency.

* vt: detect and ignore OSC codes.Adam Borowski2014-02-28
| | | | | | | | | | | | | | | | | | | | | | These can be used to send commands consisting of an arbitrary string to the terminal, most often used to set a terminal's window title or to redefine the colour palette. Our console doesn't use OSC, unlike everything else, which can lead to junk being displayed if a process sends such a code unconditionally. The rules for termination follow established practice rather than Ecma-48. Ecma-48 requires the string to use only byte values 0x08..0x0D and 0x20..0x7E, terminated with either ESC \ or 0x9C. This would disallow using 8-bit characters, which are reasonable for example in window titles. A widespread idiom is to terminate with 0x07. The behaviour for other control characters differs between terminal emulators, I followed libvte and xterm: * 0x07 and ESC anything terminate * nothing else terminates, all 8-bit values including 0x9C are considered a part of the string Signed-off-by: Adam Borowski <kilobyte@angband.pl> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

However this does not happen if generic MTD_NAND framework is built as module (CONFIG_MTD_NAND=m). Therefore, when MTD/NAND and MTD/NAND/OMAP2 modules are loaded, they are unable to find any matching platform_device and remain un-binded. This causes on board NAND flash to remain un-detected.

There is code in the regulator core to deal with situations where no regulator is specified and provide a dummy, but that works on DT-based boards only. The situation can be remedied by adding a dummy regulator during board initialization.

What the bug is: There is a problem caused by an invalid calculation of n_voltages in the driver. This n_voltages value has the potential to be different for each regulator. The value for linear_min_sel is set as DA9063_V##regl_name# which can be different depending upon the regulator. This is chosen according to the following definitions in the DA9063 registers.h file: DA9063_VLDO1_BIAS 0 DA9063_VLDO2_BIAS 0 DA9063_VLDO3_BIAS 0 DA9063_VLDO4_BIAS 0 DA9063_VLDO5_BIAS 2 DA9063_VLDO6_BIAS 2 DA9063_VLDO7_BIAS 2 DA9063_VLDO8_BIAS 2 DA9063_VLDO9_BIAS 3 DA9063_VLDO10_BIAS 2 DA9063_VLDO11_BIAS 2 The calculation for n_voltages is valid for LDOs whose BIAS value is zero but this is not correct for those LDOs which have a non-zero value. What the fix is: In order to take into account the non-zero linear_min_sel value which is set for the regulators LDO5, LDO6, LDO7, LDO8, LDO9, LDO10 and LDO11, the calculation for n_voltages should take into account the missing term defined by DA9063_V##regl_name#. This will in turn allow the core constraints calculation to set the maximum voltage limits correctly and therefore allow users to apply the maximum expected voltage to all of the LDOs.
