This patch creates the l4_cfg and l4_wkup interconnects for OMAP4, and moves some of the generic peripherals under it. System control module support is added to the device tree also, and the existing SCM related functionality is moved under it.

This patch creates an l4_wkup interconnect for AM43xx, and moves some of the generic peripherals under it. System control module nodes are moved under this new interconnect also, and the SCM clock layout is changed to use the renamed SCM nodea as the clock provider.

Pinmux node should be a reference to the base one, not a complete re-write of it. Having the node like this also prevents modifying the node layout in the base am4372.dtsi file, which is needed for control module changes. Signed-off-by: NTero Kristo <t-kristo@ti.com>

Control module driver needs to support syscon for register accesses, as the DT hierarchy for control module driver is going to be changed. All the control module related features will be moved under control module node, including clocks, pinctrl, and generic configuration register access. Temporary iomap is still provided very early in the boot for access while syscon is not yet ready. Signed-off-by: NTero Kristo <t-kristo@ti.com>

The compatible DT node is now passed with the prm init, so there is no need to do node matching here again. Added a new flag to the init data also, to detect default IRQ support for OMAP4. Also, any booting omap4 DT setup always has a PRM node, so there is no need to check against the special case where it would be missing. Signed-off-by: NTero Kristo <t-kristo@ti.com>

There is no need to provide the control module base address through a low-level API from the low-level IO init, as this information is available through DT. This patch adds a new API to initialize the control module though, but mostly makes the old API obsolete. The old API can be completely removed once OMAP3 is made DT only.

Splits the clock provider init out of the PRM driver and moves it to clock driver. This is needed so that once the PRCM drivers are separated, they can logically just access the clock driver not needing to go through common PRM code. This would be wrong in the case of control module for example. Signed-off-by: NTero Kristo <t-kristo@ti.com>

Convert the following where appropriate: (1) S_ISLNK(dentry->d_inode) to d_is_symlink(dentry). (2) S_ISREG(dentry->d_inode) to d_is_reg(dentry). (3) S_ISDIR(dentry->d_inode) to d_is_dir(dentry). This is actually more complicated than it appears as some calls should be converted to d_can_lookup() instead. The difference is whether the directory in question is a real dir with a ->lookup op or whether it's a fake dir with a ->d_automount op. In some circumstances, we can subsume checks for dentry->d_inode not being NULL into this, provided we the code isn't in a filesystem that expects d_inode to be NULL if the dirent really *is* negative (ie. if we're going to use d_inode() rather than d_backing_inode() to get the inode pointer). Note that the dentry type field may be set to something other than DCACHE_MISS_TYPE when d_inode is NULL in the case of unionmount, where the VFS manages the fall-through from a negative dentry to a lower layer. In such a case, the dentry type of the negative union dentry is set to the same as the type of the lower dentry. However, if you know d_inode is not NULL at the call site, then you can use the d_is_xxx() functions even in a filesystem. There is one further complication: a 0,0 chardev dentry may be labelled DCACHE_WHITEOUT_TYPE rather than DCACHE_SPECIAL_TYPE. Strictly, this was intended for special directory entry types that don't have attached inodes. The following perl+coccinelle script was used: use strict; my @callers; open($fd, 'git grep -l \'S_IS[A-Z].*->d_inode\' |') || die "Can't grep for S_ISDIR and co. callers"; @callers = <$fd>; close($fd); unless (@callers) { print "No matches\n"; exit(0); } my @cocci = ( '@@', 'expression E;', '@@', '', '- S_ISLNK(E->d_inode->i_mode)', '+ d_is_symlink(E)', '', '@@', 'expression E;', '@@', '', '- S_ISDIR(E->d_inode->i_mode)', '+ d_is_dir(E)', '', '@@', 'expression E;', '@@', '', '- S_ISREG(E->d_inode->i_mode)', '+ d_is_reg(E)' ); my $coccifile = "tmp.sp.cocci"; open($fd, ">$coccifile") || die $coccifile; print($fd "$_\n") || die $coccifile foreach (@cocci); close($fd); foreach my $file (@callers) { chomp $file; print "Processing ", $file, "\n"; system("spatch", "--sp-file", $coccifile, $file, "--in-place", "--no-show-diff") == 0 || die "spatch failed"; } [AV: overlayfs parts skipped] Signed-off-by: NDavid Howells <dhowells@redhat.com> Signed-off-by: NAl Viro <viro@zeniv.linux.org.uk>

In commit c441d4a5 ("MIPS: mm: Only build one microassembler that is suitable"), the Makefile at arch/mips/mm was rewritten to only build the "right" microassembler file, depending on whether CONFIG_CPU_MICROMIPS is set or not. In the files, however, there are still preprocessor definitions depending on CONFIG_CPU_MICROMIPS. The #ifdef around them can now never evaluate to true, so let's remove them altogether. This inconsistency was found using the undertaker-checkpatch tool. Signed-off-by: NAndreas Ruprecht <rupran@einserver.de> Reviewed-by: NMaciej W.
