The conversion to per bus type registration functions means we don't need to do module_get()s to hold the bus types in memory (their users will link to them) so we removed all those calls. This left module_put() calls in the cleanup paths which aren't needed and which cause unbalanced puts if we ever try to unload anything.

Factor out the register read/write code to use the register map API. We still need some wm831x specific code and locking in place to check that the user key is handled correctly but only on the write side, reads are not affected by the key.

It is useful for the register cache code to be able to specify the default values for the device registers. The major use is when restoring the register cache after suspend, knowing the register defaults allows us to skip registers that are at their default values when we resume which can be a substantial win on larger modern devices. For some devices (mostly older ones) the hardware does not support readback so the only way we can know the values is from code and so initializing the cache with default values makes it much easier for drivers work with read/modify/write updates.

Let userspace know what the access map for the device is. This is helpful for verifying that the access map is correctly configured and could also be useful for programs that try to work with the data. File format is: register: R W V P where R, W, V and P are 'y' or 'n' showing readable, writable, volatile and precious respectively. Signed-off-by: NMark Brown <broonie@opensource.wolfsonmicro.com>

CONFIG_REGMAP_I2C/SPI are set to m when selected by a tristate config option that's set to m. The regmap modules don't specify a license, so fail to link to regmap_init at load time, since that is EXPORT_SYMBOL_GPL. Fix this by specifying a license for the regmap modules.

Copy over the read parts of the ASoC debugfs implementation into regmap, allowing users to see what the register values the device has are at runtime. The implementation, especially the support for seeking, is mostly due to Dimitris Papastamos' work in ASoC. Signed-off-by: NMark Brown <broonie@opensource.wolfsonmicro.com>

Trace single register reads and writes, plus start/stop tracepoints for the actual I/O to see where we're spending time. This makes it easy to have always on logging without overwhelming the logs and also lets us take advantage of all the context and time information that the trace subsystem collects for us. We don't currently trace register values for bulk operations as this would add complexity and overhead parsing the cooked data that's being worked with.

When doing a single register write we use work_buf for both the register and the value with the buffer formatted for sending directly to the device so we can just do a write() directly. This saves allocating a temporary buffer if we can't do gather writes and is likely to be faster than doing a gather write. Signed-off-by: NMark Brown <broonie@opensource.wolfsonmicro.com>

Some devices are sensitive to reads on their registers, especially for things like clear on read interrupt status registers. Avoid creating problems with these with things like debugfs by allowing drivers to tell the core about them. If a register is marked as precious then the core will not internally generate any reads of it. Signed-off-by: NMark Brown <broonie@opensource.wolfsonmicro.com>

This is currently unused but we need to know which registers exist and their properties in order to implement diagnostics like register map dumps and the cache features. We use callbacks partly because properties can vary at runtime (eg, through access locks on registers) and partly because big switch statements are a good compromise between readable code and small data size for providing information on big register maps.

Commit d006199e72a9 ("serial: sh-sci: Regtype probing doesn't need to be fatal.") made sci_init_single() return when sci_probe_regmap() succeeds, although it should return when sci_probe_regmap() fails. This causes systems using the serial sh-sci driver to crash during boot. Fix the problem by using the right return condition. Signed-off-by: NRafael J.

Since commit 1eb19a12 ("lib/sha1: use the git implementation of SHA-1"), the ARM SHA1 routines no longer work. The reason? They depended on the larger 320-byte workspace, and now the sha1 workspace is just 16 words (64 bytes). So the assembly version would overwrite the stack randomly. The optimized asm version is also probably slower than the new improved C version, so there's no reason to keep it around. At least that was the case in git, where what appears to be the same assembly language version was removed two years ago because the optimized C BLK_SHA1 code was faster.
