regmap: regcache-rbtree: Clean new present bits on present bitmap resize

2015-07-29T14:10:13Z

When inserting a new register into a block, the present bit map size is increased using krealloc. krealloc does not clear the additionally allocated memory, leaving it filled with random values. Result is that some registers are considered cached even though this is not the case. Fix the problem by clearing the additionally allocated memory. Also, if the bitmap size does not increase, do not reallocate the bitmap at all to reduce overhead.

regmap: Fix possible shift overflow in regmap_field_init()

2015-06-16T11:58:22Z

The way the mask is generated in regmap_field_init() is wrong. Indeed, a field initialized with msb = 31 and lsb = 0 provokes a shift overflow while calculating the mask field. On some 32 bits architectures, such as x86, the generated mask is 0, instead of the expected 0xffffffff. This patch uses GENMASK() to fix the problem, as this macro is already safe regarding shift overflow. Signed-off-by: Maxime Coquelin Signed-off-by: Mark Brown Cc: stable@vger.kernel.org

regmap: Fix regmap_bulk_read in BE mode

2015-06-15T15:02:16Z

In big endian mode regmap_bulk_read gives incorrect data for byte reads. This is because memcpy of a single byte from an address after full word read gives different results when endianness differs. ie. we get little-end in LE and big-end in BE.

regmap: kill off set_irq_flags usage

2015-06-09T19:08:57Z

set_irq_flags is ARM specific with custom flags which have genirq equivalents. Convert drivers to use the genirq interfaces directly, so we can kill off set_irq_flags. The translation of flags is as follows: IRQF_VALID -> !IRQ_NOREQUEST IRQF_PROBE -> !IRQ_NOPROBE IRQF_NOAUTOEN -> IRQ_NOAUTOEN For IRQs managed by an irqdomain, the irqdomain core code handles clearing and setting IRQ_NOREQUEST already, so there is no need to do this in .map() functions and we can simply remove the set_irq_flags calls. Some users also set IRQ_NOPROBE and this has been maintained although it is not clear that is really needed. There appears to be a great deal of blind copy and paste of this code.

regmap: Introduce regmap_get_reg_stride

2015-05-22T11:19:21Z

This patch introduces regmap_get_reg_stride() function which would be used by the infrastructures like nvmem framework built on top of regmap. Mostly this function would be used for sanity checks on inputs within such infrastructure. Signed-off-by: Srinivas Kandagatla Signed-off-by: Mark Brown
