regmap-irq: Remove unused mask_invert flag

mask_invert is deprecated and no longer used; it can now be removed. Signed-off-by: Aidan MacDonald Link: https://lore.kernel.org/r/20230216223200.150679-2-aidanmacdonald.0x0@gmail.com Signed-off-by: Mark Brown

regmap: Reorder fields in 'struct regmap_bus' to save some memory

2023-02-14T13:25:22+00:00

Group some bool variables to reduce hole and avoid padding. On x86_64, this shrinks the size from 136 to 128 bytes. As an example: $ size drivers/base/regmap/regmap-fsi.o (Before) text data bss dec hex filename 4837 136 0 4973 136d drivers/base/regmap/regmap-fsi.o $ size drivers/base/regmap/regmap-fsi.o (After) text data bss dec hex filename 4701 136 0 4837 12e5 drivers/base/regmap/regmap-fsi.o Signed-off-by: Christophe JAILLET Link: https://lore.kernel.org/r/077ca39622c8870a3ea932298a9cec34f7a8295a.1676363976.git.christophe.jaillet@wanadoo.fr Signed-off-by: Mark Brown

regmap: Rework regmap_mdio_c45_{read|write} for new C45 API.

2023-01-16T13:16:09+00:00

The MDIO subsystem is getting rid of MII_ADDR_C45 and thus also encoding associated encoding of the C45 device address and register address into one value. regmap-mdio also uses this encoding for the C45 bus. Move to the new C45 helpers for MDIO access and provide regmap-mdio helper macros.

regmap-irq: Add handle_mask_sync() callback

2022-12-09T17:39:33+00:00

Provide a public callback handle_mask_sync() that drivers can use when they have more complex IRQ masking logic. The default implementation is regmap_irq_handle_mask_sync(), used if the chip doesn't provide its own callback.

fsi: Add regmap and refactor sbefifo

2022-11-25T21:26:29+00:00

Merge series from Eddie James : The SBEFIFO hardware can now be attached over a new I2C endpoint interface called the I2C Responder (I2CR). In order to use the existing SBEFIFO driver, add a regmap driver for the FSI bus and an endpoint driver for the I2CR. Then, refactor the SBEFIFO and OCC drivers to clean up and use the new regmap driver or the I2CR interface. This branch just has the regmap change so it can be shared with the FSI code.

regmap: add regmap_might_sleep()

2022-11-22T12:23:17+00:00

With the dawn of MMIO gpio-regmap users, it is desirable to let gpio-regmap ask the regmap if it might sleep during an access so it can pass that information to gpiochip. Add a new regmap_might_sleep() to query the regmap. Signed-off-by: Michael Walle Link: https://lore.kernel.org/r/20221121150843.1562603-1-michael@walle.cc Signed-off-by: Mark Brown

regmap: Support accelerated noinc operations

2022-08-17T12:00:31+00:00

Several architectures have accelerated operations for MMIO operations writing to a single register, such as writesb, writesw, writesl, writesq, readsb, readsw, readsl and readsq but regmap currently cannot use them because we have no hooks for providing an accelerated noinc back-end for MMIO. Solve this by providing reg_[read/write]_noinc callbacks for the bus abstraction, so that the regmap-mmio bus can use this. Currently I do not see a need to support this for custom regmaps so it is only added to the bus. Callbacks are passed a void * with the array of values and a count which is the number of items of the byte chunk size for the specific register width.

regmap: mmio: Introduce IO accessors that can talk to IO port

2022-08-15T00:20:10+00:00

Some users may use regmap MMIO for IO ports, and this can be done by assigning ioreadXX()/iowriteXX() and their Big Endian counterparts to the regmap context. Add IO port support with a corresponding flag added. While doing that, make sure that user won't select relaxed MMIO access along with IO port because the latter have no relaxed variants.
