* remove mentionings of devfs in documentationAdrian Bunk2006-10-035-12/+5
| | | | | | | | | Now that devfs is removed, there's no longer any need to document how to do this or that with devfs. This patch includes some improvements by Joe Perches. Signed-off-by: Adrian Bunk <bunk@stusta.de>

| * [ARM] 3848/1: pxafb: Add option of fixing video modes and spitz QVGA mode ↵Richard Purdie2006-10-022-32/+78
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | support Add the ability to have pxafb use only certain fixed video modes (selected on a per platform basis). This is useful on production hardware such as the Zaurus cxx00 models where the valid modes are known in advance and any other modes could result in hardware damage. Following this, add support for the cxx00 QVGA mode. Mode information is passed to the lcd_power call to allowing the panel drivers to configure the display hardware accordingly (corgi_lcd already contains the functionality for the cxx00 panel). This mirrors the setup already used by w100fb. Signed-off-by: Richard Purdie <rpurdie@rpsys.net> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| * | [SERIAL] add PNP IDs for FPI based touchscreensMatthew Garrett2006-10-011-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Compaq TC1000 and Fujitsu Stylistic range of tablet machines use touchscreens from FPI. These are implemented as serial interfaces, generally exposed in the ACPIPNP information on the system. This patch adds them to the 8250_pnp driver tables, avoiding the need to mess around with setserial to set them up. I haven't been able to confirm what FUJ02B5, FUJ02BA and FUJ02BB are. FUJ02B1 refers to the controller for the system hotkeys. FUJ02BC appears to be the last in the range - after this, they moved to Wacom-based systems.

| * | [SERIAL] Fix oops when removing suspended serial portRussell King2006-10-011-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A serial card might have been removed when the system is resumed. This results in a suspended port being shut down, which results in the ports shutdown method being called twice in a row. This causes BUGs. Avoid this by tracking the suspended state separately from the initialised state. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | asm/serial.h is supposed to contain the definitions for the architecture specific 8250 ports for the 8250 driver. It may also define BASE_BAUD, but this is the base baud for the architecture specific ports _only_. Therefore, nothing other than the 8250 driver should be including this header file. In order to move towards this goal, here is a patch which removes some of the more obvious incorrect includes of the file.

It's been in the linux-omap tree for some time and with it applied to a vanilla Linus git tree the serial console on the Amstrad Delta (which is OMAP1510 based and whose initial bootloader runs at 115200) works fine (it doesn't without it).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the existing code, Nokia only make single-port cards, but are detected as multi-port cards. Handle this in roughly the same way via the config quirk - forcing it to be a real single port card (info->multi=0) changes the way we allocate the IO memory, which might stop the card working.

Now, with QE on the pipeline, and to make DTS descriptions more clear, fs_no features relevant SoC part number, with additional field to describe the SoC type. Another reason for that is now not only fs_enet is going to utilize those stuff. There might be UART, HLDC, and even USB, so to prevent confusion and be ready for upcoming OF_device transfer, fs_enet and cpm_uart drivers were updated in that concern, as well as the relevant DTS.

This is more like the 2.4 legacy stuff, and is at least confusing and unclear now. To keep the world comfortable, a new mechanism is introduced: before accessing specific immr register/register set, one needs to map it, using cpm2_map(<reg>), for instance, access to CPM command register will look like volatile cpm_cpm2_t *cp = cpm2_map(im_cpm); keeping the code clear, yet without "already defined somewhere" cpm2_immr. So far, unmapping code is not implemented, but it's not a big deal to add it, if the whole idea makes sense. Signed-off-by: Vitaly Bordug <vbordug@ru.mvista.com>

This need no longer exists, but we still have an arbitrary limit. So remove MAX_MD_DEVS and allow as many devices as we can fit into the 'minor' part of a device number. Also remove some useless noise at init time (which reports MAX_MD_DEVS) and remove MD_THREAD_NAME_MAX which hasn't been used for a while.

This uses the same mechanisms as 'resync' and so reports in the kernel logs that a resync is being started. This understandably confuses/worries people. Also the text in /proc/mdstat suggests a 'resync' is happen when it is just a check. This patch changes those messages to be more specific about what is happening.

This patch adds the appropriate functions which just check the 'congested' status of all active members (with appropriate locking). raid1 read_balance should be modified to prefer devices where bdi_read_congested returns false. Then we could use the '&' branch rather than the '|' branch. However that should would need some benchmarking first to make sure it is actually a good idea.
