| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some devices have multiple separate register regions. Logically, one regmap would be created per region. One issue that prevents this is that each instance will attempt to create the same debugfs files. Avoid this by allowing regmaps to be named, and use the name to construct the debugfs directory name.

It has the following features and limitations: * Registers themselves may be 8, 16, 32, or 64-bit. 64-bit is only supported on 64-bit platforms. * Register offsets are limited to precisely 32-bit. * IO is performed using readl/writel, with no provision for using the __raw_readl or readl_relaxed variants.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some bus types have very fast IO.

| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The only context needed by I2C and SPI bus definitions is the device itself; this can be converted to an i2c_client or spi_device in order to perform IO on the device. However, other bus types may need more context in order to perform IO. Enable this by having regmap_init accept a bus_context parameter, and pass this to all bus callbacks. The existing callbacks simply pass the struct device here. Future bus types may pass something else.

Support such updates by allowing drivers to register update sets with the core. These updates will be written to the device immediately and will also be rewritten when the cache is synced. The assumption is that the reason for resyncing the cache will always be that the device has been powered off. If this turns out to not be the case then a separate operation can be provided. Currently the implementation only allows a single set of updates to be specified for a device, this could be extended in future. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

This worked in the past, because registers without a explicit default were assumed to have a default value of 0. This was changed in commit b03622a8 ("regmap: Ensure rbtree syncs registers set to zero properly"). As a result registers, which have a raw default value of 0 are now assumed to have no default. This again can result in unnecessary writes when syncing the cache. It will also result in unnecessary reads for e.g. the first update operation. In the case where readback is not possible this will even let the update operation fail, if the register has not been written to before. So this patch removes the check. Instead it adds a check to ignore raw defaults for registers which are volatile, since those registers are not cached.
