2022-10-05T02:12:16Z

Pull regmap updates from Mark Brown: "This has been a busy release for regmap with one thing and other, there's been an especially large interest in MMIO regmaps for some reason. The bulk of the changes are cleanups but there are several user visible changes too: - Support for I/O ports in regmap-mmio - Support for accelerated noinc operations in regmap-mmio - Support for tracing the register values in bulk operations" * tag 'regmap-v6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap: regmap: mmio: replace return 0 with break in switch statement regmap: spi-avmm: Use swabXX_array() helpers regmap: mmio: Use swabXX_array() helpers swab: Add array operations regmap: trace: Remove unneeded blank lines regmap: trace: Remove explicit castings regmap: trace: Remove useless check for NULL for bulk ops regmap: mmio: Fix rebase error regmap: check right noinc bounds in debug print regmap: introduce value tracing for regmap bulk operations regmap/hexagon: Properly fix the generic IO helpers regmap: mmio: Support accelerared noinc operations regmap: Support accelerated noinc operations regmap: Make use of get_unaligned_be24(), put_unaligned_be24() regmap: mmio: Fix MMIO accessors to avoid talking to IO port regmap: mmio: Introduce IO accessors that can talk to IO port regmap: mmio: Get rid of broken 64-bit IO regmap: mmio: Remove mmio_relaxed member from context

regmap: mmio: replace return 0 with break in switch statement

2022-09-22T11:33:18Z

Variable min_stride is assigned a value that is never read, fix this by replacing the return 0 with a break statement. This also makes the case statement consistent with the other cases in the switch statement.

regmap: spi-avmm: Use swabXX_array() helpers

2022-09-07T11:42:27Z

Since we have a few helpers to swab elements of a given size in an array use them instead of open coded variants. Signed-off-by: Andy Shevchenko Reviewed-by: Linus Walleij Link: https://lore.kernel.org/r/20220831212744.56435-3-andriy.shevchenko@linux.intel.com Signed-off-by: Mark Brown

regmap: trace: Remove useless check for NULL for bulk ops

2022-09-05T12:09:43Z

If the buffer pointer is NULL we already are in troubles since regmap bulk API expects caller to provide valid parameters, it dereferences that without any checks before we call for traces. Moreover, the current code will print garbage in the case of buffer is NULL and length is not 0.

regmap: check right noinc bounds in debug print

2022-08-23T16:47:16Z

We were using the wrong bound in the debug prints: this needs to be the number of elements, not the number of bytes, since we're indexing into an element-size typed array.

regmap: introduce value tracing for regmap bulk operations

2022-08-23T12:04:55Z

Currently, only one-register io operations support tracepoints with value logging. For the regmap bulk operations developer can view hw_start/hw_done tracepoints with starting reg number and registers count to be reading or writing. This patch injects tracepoints with dumping registers values in the hex format to regmap bulk reading and writing.
