regmap: spmi: Fix regmap_spmi_ext_read in multi-byte case

2016-05-19T00:06:48Z

commit dec8e8f6e6504aa3496c0f7cc10c756bb0e10f44 upstream. Specifically for the case of reads that use the Extended Register Read Long command, a multi-byte read operation is broken up into 8-byte chunks. However the call to spmi_ext_register_readl() is incorrectly passing 'val_size', which if greater than 8 will always fail. The argument should instead be 'len'.

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

debugfs: Pass bool pointer to debugfs_create_bool()

2015-10-04T10:36:07Z

Its a bit odd that debugfs_create_bool() takes 'u32 *' as an argument, when all it needs is a boolean pointer. It would be better to update this API to make it accept 'bool *' instead, as that will make it more consistent and often more convenient. Over that bool takes just a byte. That required updates to all user sites as well, in the same commit updating the API. regmap core was also using debugfs_{read|write}_file_bool(), directly and variable types were updated for that to be bool as well.

regmap: debugfs: simplify regmap_reg_ranges_read_file() slightly

2015-09-30T19:31:16Z

By printing the newline character to entry, we can avoid accounting for it manually in several places. Signed-off-by: Rasmus Villemoes Signed-off-by: Mark Brown

regmap: debugfs: use memcpy instead of snprintf

2015-09-30T19:31:16Z

Since we know the length of entry and that there's room enough in the output buffer, using memcpy instead of snprintf is simpler and cheaper. Signed-off-by: Rasmus Villemoes Signed-off-by: Mark Brown

regmap: debugfs: use snprintf return value in regmap_reg_ranges_read_file()

2015-09-30T19:31:15Z

Calling strlen() no less than three times on entry is silly. Since we're formatting into a buffer with plenty of room, there's no chance of truncation, so snprintf() has actually returned the value we want, meaning we don't even have to call strlen once.
