regmap: Allow buses to provide a custom update_bits() operation Some buses provide a native _update_bits() operation which for uncached registers is faster than doing a read/modify/write cycle as it is a single bus transaction. Add support for implementing this to regmap. # gpg: Signature made Tue 06 Oct 2015 16:21:47 BST using RSA key ID 5D5487D0 # gpg: Oops: keyid_from_fingerprint: no pubkey # gpg: Oops: keyid_from_fingerprint: no pubkey # gpg: key 00000000 occurs more than once in the trustdb # gpg: key 16005C11: no public key for trusted key - skipped # gpg: key 16005C11 marked as ultimately trusted # gpg: Good signature from "Mark Brown " # gpg: aka "Mark Brown " # gpg: aka "Mark Brown " # gpg: aka "Mark Brown " # gpg: aka "Mark Brown " # gpg: aka "Mark Brown "

regmap: Allow installing custom reg_update_bits function

2015-10-06T15:12:34Z

This commit allows installing a custom reg_update_bits function for cases where the hardware provides a mechanism to set or clear register bits without a read/modify/write cycle. Such is the case with the Microchip ENCX24J600. If a custom reg_update_bits function is provided, it will only be used against volatile registers. Signed-off-by: Jon Ringle Signed-off-by: Mark Brown

regmap: irq: add support for chips who have separate unmask registers

2015-09-17T10:46:09Z

Some chips have separate unmask registers from mask registers for some consideration of concurrency SMP write performance. And this patch adds a flag for it. An user will be CSR SiRFSoC ARM chips. Signed-off-by: Guo Zeng Signed-off-by: Barry Song Signed-off-by: Mark Brown

regmap: regmap max_raw_read/write getter functions

2015-08-30T09:19:22Z

Add functions to access the maximum size we can read/write using regmap_raw_read/write(). This helps drivers that need to know how much they can write with the raw functions without problems. There are some devices (e.g. bmc150) that have fifos as registers which need to be read in specific chunks otherwise samples are dropped. Signed-off-by: Markus Pargmann Signed-off-by: Mark Brown

regmap: Introduce max_raw_read/write for regmap_bulk_read/write

2015-08-30T09:19:22Z

There are some buses which have a limit on the maximum number of bytes that can be send/received. An example for this is I2C_FUNC_SMBUS_I2C_BLOCK which does not support any reads/writes of more than 32 bytes. The regmap_bulk operations should still be able to utilize the full 32 bytes in this case. Signed-off-by: Markus Pargmann Signed-off-by: Mark Brown
