Config registers provide a more uniform approach to handling irq type registers. They are essentially an extension of the virtual registers used by the qcom-pm8008 driver. Config registers can be represented as a 2D array: config_base[0] reg0,0 reg0,1 reg0,2 reg0,3 config_base[1] reg1,0 reg1,1 reg1,2 reg1,3 config_base[2] reg2,0 reg2,1 reg2,2 reg2,3 There are 'num_config_bases' base registers, each of which is used to address 'num_config_regs' registers. The addresses are calculated in the same way as for other bases. It is assumed that an irq's type is controlled by one column of registers; that column is identified by the irq's 'type_reg_offset'. The set_type_config() callback is responsible for updating the config register contents. It receives an array of buffers (each represents a row of registers) and the index of the column to update, along with the 'struct regmap_irq' description and requested irq type. Buffered values are written to registers in regmap_irq_sync_unlock(). Note that the entire register contents are overwritten, which is a minor change in behavior from type registers via 'type_base'.

Commit a71411db ("regmap: irq: add chip option mask_writeonly") introduced the mask_writeonly option, but it isn't used now and it appears it's never been used by any in-tree drivers. The motivation for the option is mentioned in the commit message, Some irq controllers have writeonly/multipurpose register layouts. In those cases we read invalid data back. [...] The option causes mask register updates to use regmap_write_bits() instead of regmap_update_bits(). However, regmap_write_bits() doesn't solve the reading invalid data problem. It's still a read-modify-write op like regmap_update_bits(). The difference is that 'update bits' will only write the new value if it is different from the current value, while 'write bits' will write the new value unconditionally, even if it's the same as the current value. This seems like a bit of a specialized use case and probably isn't that useful for regmap-irq, so let's just remove the option and go back to using an 'update bits' op for the mask registers. We can always add the option back if some driver ends up needing it in the future. Signed-off-by:

regmap_irq_update_bits() is misnamed and should only be used for updating mask registers, since it checks the mask_writeonly flag. However, it was also used for updating wake and type registers. It's safe to replace these uses with regmap_update_bits() because there are no users of the mask_writeonly flag. Signed-off-by:

Check types_supported instead of checking type_rising/falling_val when using type_in_mask interrupts. This makes the intent clearer and allows a type_in_mask irq to support level or edge triggers, rather than only edge triggers. Update the documentation and comments to reflect the new behavior. This shouldn't affect existing drivers, because if they didn't set types_supported properly the type buffer wouldn't be updated. Signed-off-by:

For devices with no cache it can make sense to use cache only mode as a mechanism for trapping writes to hardware which is inaccessible but since no cache is equivalent to cache bypass we force such devices into bypass mode. This means that our check that bypass and cache only mode aren't both enabled simultanously is less sensible for devices without a cache so relax it. Signed-off-by:

There are some functions that were missed by commit d77e7456 ("regmap: Add bulk read/write callbacks into regmap_config") when support to define bulk read/write callbacks in regmap_config was introduced. The regmap_bulk_write() and regmap_noinc_write() functions weren't changed to use the added map->write instead of the map->bus->write handler. Also, the regmap_can_raw_write() was not modified to take map->write into account. So will only return true if a bus with a .write callback is set.

Before adding support to define bulk read/write callbacks in regmap_config by the commit d77e7456 ("regmap: Add bulk read/write callbacks into regmap_config"), the regmap_noinc_read() function returned an errno early a map->bus->read callback wasn't set. But that commit dropped the check and now a call to _regmap_raw_read() is attempted even when bulk read operations are not supported. That function checks for map->read anyways but there's no point to continue if the read can't succeed. Also is a fragile assumption to make so is better to make it fail earlier.

We have set/clear/test operations for regmap, but not for regmap_field yet. So let's introduce regmap_field helpers too. In many instances regmap_field_update_bits() is used for simple bit setting and clearing. In these cases the last argument is redundant and we can hide it with a static inline function. This adds three new helpers for simple bit operations: set_bits, clear_bits and test_bits (the last one defined as a regular function). Signed-off-by:

The bluetooth code uses our bitmap infrastructure for the two bits (!) of connection setup flags, and in the process causes odd problems when it converts between a bitmap and just the regular values of said bits. It's completely pointless to do things like bitmap_to_arr32() to convert a bitmap into a u32. It shoudln't have been a bitmap in the first place. The reason to use bitmaps is if you have arbitrary number of bits you want to manage (not two!), or if you rely on the atomicity guarantees of the bitmap setting and clearing. The code could use an "atomic_t" and use "atomic_or/andnot()" to set and clear the bit values, but considering that it then copies the bitmaps around with "bitmap_to_arr32()" and friends, there clearly cannot be a lot of atomicity requirements. So just use a regular integer. In the process, this avoids the warnings about erroneous use of bitmap_from_u64() which were triggered on 32-bit architectures when conversion from a u64 would access two words (and, surprise, surprise, only one word is needed - and indeed overkill - for a 2-bit bitmap). That was always problematic, but the compiler seems to notice it and warn about the invalid pattern only after commit 0a97953f ("lib: add bitmap_{from,to}_arr64") changed the exact implementation details of 'bitmap_from_u64()', as reported by Sudip Mukherjee and Stephen Rothwell.

Pull mount handling updates from Al Viro: "Cleanups (and one fix) around struct mount handling. The fix is usermode_driver.c one - once you've done kern_mount(), you must kern_unmount(); simple mntput() will end up with a leak. Several failure exits in there messed up that way... In practice you won't hit those particular failure exits without fault injection, though" * tag 'pull-18-rc1-work.mount' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: move mount-related externs from fs.h to mount.h blob_to_mnt(): kern_unmount() is needed to undo kern_mount() m->mnt_root->d_inode->i_sb is a weird way to spell m->mnt_sb... linux/mount.h: trim includes uninline may_mount() and don't opencode it in fspick(2)/fsopen(2)
