2015-03-31ARM: OMAP4+: PRM: determine prm_device_inst based on DT compatibilityTero Kristo5-18/+42
PRM device instance offset is now provided through the prm_init_data. This gets rid of some cpu_is_X / soc_is_X calls from PRM core code, preparing for PRM to be its own separate driver. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-03-31ARM: OMAP2+: PRM: move SoC specific init calls within a generic APITero Kristo15-39/+90
This gets rid of need for some exported driver APIs, and simplifies the initialization of the PRM driver. Done in preparation to make PRM a separate driver. The init data is now also passed to the SoC specific implementations, allowing future expansion to add feature flags etc. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-03-27ARM: OMAP2+: control: determine control module base address from DTTero Kristo5-30/+61
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. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-03-27ARM: OMAP2+: PRM: determine PRM base address from device treeTero Kristo7-20/+52
There is no need to provide the PRM base address through a low-level API from the low-level IO init, as this information is available through DT. Re-routed the parsing function to be called from the PRM drivers also to simplify the implementation under io.c. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-03-27ARM: OMAP2+: CM: determine CM base address from device treeTero Kristo9-19/+81
There is no need to provide the CM base address through a low-level API from the low-level IO init, as this information is available through DT. Re-routed the parsing function to be called from the CM drivers also to simplify the implementation under io.c. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-03-27ARM: OMAP2+: PRCM: split PRCM module init to their own driver filesTero Kristo6-21/+106
Splits the clock related provider module inits under their own driver files. Previously this was done for all modules under the common PRM driver. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-03-27ARM: OMAP2+: clock: move clock provider infrastructure to clock driverTero Kristo3-44/+75
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: Tero Kristo <t-kristo@ti.com>
2015-03-25ARM: OMAP2+: PRCM: add support for static clock memmap indicesTero Kristo2-29/+58
All clock provider related drivers will now register their iomaps with a static index. This makes it easier to split up the individual drivers to their own files in subsequent patches. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-03-25ARM: OMAP4: PRM: move omap4xxx_prm_init earlier in init orderTero Kristo1-1/+1
OMAP4 has different ordering of PRM and CM init calls in the early init. Re-oder these accordingly for OMAP4 also. This is needed so that we can do some optimizations in the following patches for the PRCM init. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-03-25ARM: OMAP4+: CM: move omap_cm_base_init under OMAP4 CM driverTero Kristo3-6/+3
There is no need to call this separately from io.c, rather this can be done commonly under the CM driver. Also, this patch makes the API static, as it is no longer used outside the driver file. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-03-25ARM: OMAP4+: PRM: move omap_prm_base_init under OMAP4 PRM driverTero Kristo2-4/+2
There is no need to call this separately from io.c, rather this can be done commonly under the PRM driver. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-03-25ARM: OMAP3+: PRM: add common APIs for prm_vp_check/clear_txdoneTero Kristo9-25/+60
PRM driver now only exports a generic API for clearing / checking VP txdone status. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-03-25ARM: OMAP2+: PRM: add generic API for clear_mod_irqsTero Kristo8-28/+47
OMAP2/3 now use generic API for the prm_clear_mod_irqs, the SoC specific implementation details are provided through prm_ll_data. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-03-25ARM: OMAP3: PRM: invert the wkst_mask for the prm_clear_mod_irqsTero Kristo3-14/+14
This makes the API the same as used with OMAP2, and makes it possible to implement a generic driver API for the functionality. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-03-25ARM: OMAP2+: PRCM: rename of_prcm_init to omap_prcm_initTero Kristo3-3/+9
This avoids conflicts in the global namespace, and is more descriptive of the purpose anyway. Signed-off-by: Tero Kristo <t-kristo@ti.com>

2015-02-22VFS: (Scripted) Convert S_ISLNK/DIR/REG(dentry->d_inode) to d_is_*(dentry)David Howells1-1/+1
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: David Howells <dhowells@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2015-02-20MIPS: ip22-gio: Remove legacy suspend/resume supportLars-Peter Clausen2-26/+0
There are currently no gio device drivers that implement suspend/resume and this patch removes the bus specific legacy suspend and resume callbacks. This will allow us to eventually remove struct bus_type legacy suspend and resume support altogether. gio device drivers wanting to implement suspend and resume can use dev PM ops which will work out of the box without further modifications necessary.

2015-02-20MIPS: Alchemy: Fix cpu clock calculationManuel Lauss1-0/+2
The current code uses bits 0-6 of the sys_cpupll register to calculate core clock speed. However this is only valid on Au1300, on all earlier models the hardware only uses bits 0-5 to generate core clock. This fixes clock calculation on the MTX1 (Au1500), where bit 6 of cpupll is set as well, which ultimately lead the code to calculate a bogus cpu core clock and also uart base clock down the line.
