* ARM: config: sort select statements alphanumericallyRussell King2012-10-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As suggested by Andrew Morton: This is a pet peeve of mine. Any time there's a long list of items (header file inclusions, kconfig entries, array initalisers, etc) and someone wants to add a new item, they *always* go and stick it at the end of the list. Guys, don't do this. Either put the new item into a randomly-chosen position or, probably better, alphanumerically sort the list. lets sort all our select statements alphanumerically. This commit was created by the following perl: while (<>) { while (/\\\s*$/) { $_ .= <>; } undef %selects if /^\s*config\s+/; if (/^\s+select\s+(\w+).*/) { if (defined($selects{$1})) { if ($selects{$1} eq $_) { print STDERR "Warning: removing duplicated $1 entry\n"; } else { print STDERR "Error: $1 differently selected\n". "\tOld: $selects{$1}\n". "\tNew: $_\n"; exit 1; } } $selects{$1} = $_; next; } if (%selects and (/^\s*$/ or /^\s+help/ or /^\s+---help---/ or /^endif/ or /^endchoice/)) { foreach $k (sort (keys %selects)) { print "$selects{$k}"; } undef %selects; } print; } if (%selects) { foreach $k (sort (keys %selects)) { print "$selects{$k}"; } } It found two duplicates: Warning: removing duplicated S5P_SETUP_MIPIPHY entry Warning: removing duplicated HARDIRQS_SW_RESEND entry and they are identical duplicates, hence the shrinkage in the diffstat of two lines. We have four testers reporting success of this change (Tony, Stephen, Linus and Sekhar.)

Drivers are also gradually getting Device Tree and IRQ domain support.

| * | spi/pl022: adopt pinctrl supportPatrice Chotard2012-09-201-3/+0
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Amend the PL022 pin controller to optionally take a pin control handle and set the state of the pins to "default" on boot and runtime resume, and to "sleep" at runtime suspend. This way we will dynamically save power on the SPI busses, for example some electronic designs may be able to ground the pins when unused instead of pull-up. Some pin controllers may want to set the pins as wake-up sources when sleeping. Effect on platforms using the PL022 driver: - If the platform does not use pin control - no semantic effect, the pinctrl stubs will kick in and resolve the situation. - Platforms using this driver and have pin control but no function defined for the PL022 need to either supply a "default" function in their map or enable pinctrl dummies so the driver is satisfied. - Platforms using this driver with hogs for setting up the PL022 pin control - stop using hogs to take the pl022 pin control handle, let the driver handle this. I'be looked at some platforms that may be affected: - SPEAr: appears to define the proper functions in their device trees and not hogging them, so things should be smooth, the driver will simply start to take its pins. - Ux500: the proper function is defined and will be taken properly by the driver. New sleep states introduced by a separate patch to ux500 but no regression, since the default state is sufficient. - U300: old hog deleted as part of this patch. - LPC32xx: does not appear to be using pinctrl. - ARM Integrator IMPD1, RealView & Versatile: does not use pinctrl.

This model will also better suit pinconf programming, which doesn't have a concept of "disable". The special-case hogging feature of pin controllers is re-written to use the regular APIs instead of special-case code. Hence, the pinmux-hogs debugfs file is removed; see the top-level pinctrl-handles files for equivalent data.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pinctrl_register_mappings() already requires that every mapping table entry have a non-NULL name field. Logically, this makes sense too; drivers should always request a specific named state so they know what they're getting. Relying on getting the first mentioned state in the mapping table is error-prone, and a nasty special case to implement, given that a given the mapping table may define multiple states for a device. Remove a small part of the documentation that talked about optionally requesting a specific state; it's mandatory now.

Update PIN_MAP_* macros to use this state name, instead of requiring the user to pass a state name in. With this change, hog entries in the mapping table are defined as those with state name PINCTRL_STATE_DEFAULT, i.e. all entries have the same name. This interacts badly with the nested iteration over mapping table entries in pinctrl_hog_maps() and pinctrl_hog_map() which would now attempt to claim each hog mapping table entry multiple times. Replacing the custom hog code with a simple pinctrl_get()/pinctrl_enable(). Update documentation and mapping tables to use this.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes a deep copy of the pinmux function map instead of keeping the copy supplied from the platform around. This makes it possible to tag the platforms map with __initdata as is also done as part of this patch. Rationale: a certain target platform (PXA) has numerous pinmux maps, many of which will be lying around unused after boot in a multi-platform binary. Instead, deep-copy the one we're going to use and tag them all __initdata so they go away after boot. ChangeLog v1->v2: - Fixup the deep copy, missed a few items on the struct, plus mark bool member non-const since we're making runtime copies if this stuff now. ChangeLog v2->v3: - Make a shallow copy (just copy the array of map structs) as Arnd noticed, string constants never get discarded by the kernel anyway, so these pointers may be safely copied over.
